yerf dog suspension modifacation
im improving upon a yerf dog 3202, i belive.i have built a daul wishbone suspension for the front which is not from a spderbox and giving myself some more ground clearance in the front i still need to get shocks for it if anyone has suggestions on what to use and where to get them.i have also streched the already rebuilt rear end for the 11hp with hydralic disk brake and have a 32mm mikuni carb.have it apart for these mods so i am going to spray it with an alk-200 epoxy paint navy blue.i would also like some bucket seats that would be cool.

looking good, keep the pics coming. I'm slowly working along the same lines. Are you increasing the width with the new front end? I'm considering going wider (the arms i'm making are 11.5 without the heim ends,--8 inch wide rims that are pretty deeply backspaced) but final width can be set by the chassis mounts. Both metalstudman and speedshopmike are using shocks from here--low cost-- dimensionally abouthe same as stock, if you want longer, then it's e-bay/craigslist time for used ATV ones if you don't have anyone locally and want to keep to a tight budget.

gas tank
i used a tank from an air compressor that burned up and cut the top off the old gas tank made some relief cuts,cut a hole in the new tank and welded the cap base on added a little body filler and it is ready to smooth weld on to the dog and paint.

I love how projects look soooo good right after fresh paint!! too bad if you drive it much it looses it's luster appearance wise to quickly. Can't wait to see it.

It looks great- I'm glad to see someone else over builds their parts- you'll never have a problem with the A-arm supports or the shock mounts- nice tank!!

Nice, I like the blue, a different shade than most. quick question for you though; do you have enough clearance between the back frame rail and the engine? I made a little header for my 6.5 and even after re-cutting it and angling it further downward, it hits that tube on the hard shots. there's about 6 inches between it and the rail-- i never thought it'd compress that far, but it does. I do see that you changed the rear shock locations.

good eyes x, the frame will be up higher when i get the shocks on. i just had it sitting there to show you guys what it will look like. i have a header as well but i wanna angle it back more and would like to build a muffler cuase it is reeeaaaly loud. so if you guys have any ideas for a muffler i would love to hear them. and thanks for the positive feed back.

you could get a higher power rated lawnmower "can" style muffler at your local hardware store, hell depot etc. look on the back of the package and it will tell what engine/hp it's for. probably around 10 bucks. the ones for the larger engines have 1 inch pipe thread openings. as
long as it's pretty far back in the system, it shouldn't restrict it too badly.

Looks great- I'm going to be technical about something as well. Yes your rear shock mount does need a gusset or two like x-bird suggested, IMO I think you're going to have a bad day when you hit a couple of bumps and your Heims are in a bind due to the fact they are max'd out sitting still, you need to have them level with the ground or nuetral when you're seated in it, right now they're pointing down and the when the front end recoils from a bounce it's going to snap/bend them.I can't see from the pic if you have the spacer tapered @ the Heim-Loved your A-arm build and I think your width looks right for the frame size

If he does have an issue with the heims, would the misalignment spacer help with that? I was looking at those the other day, it look like the spacers make it so the ball continues outside the joint to increase the amount of angular travel.

You have it right about the mis-alignment spacer- usually you use a larger Heim with the mis-alignment spacer to reduce the bolt size to gain full travel of the ball. The only issue I have is that all these little parts -bigger Heim,cone spacers,bung & mis-aligment spacers make just one ball joint about $30. a piece!(without the bolt/fastner)+ fabrication time, most standard ball joints are in the $20. range. No doubt that it's the most durable way to go assuming you buy a GOOD QUALITY Heim. A Heim bends realitively easily if it gets max'd out, so it's critical to have the ball central/nuetral to the outer case to minumize failure.

evey thing works fine. i have done many mini truck/low rider suspensions with hydraulics and air ride. those parts are just what i had on hand and i am not working right now so i cant spend any money on it. i am how ever building a rack and pinion cause the steering was the only thing that did have a problem. the linkage was not inline with the a-arms so it was pulling the passenger side wheel in when the a-arms were move up.

i'm outta work too!
let's have a keg party. my buddy told me to call it Funemployment, lol.  as long as your heims aren't at their travel limit when the suspension is topped or bottomed out they'll be fine. to help avoid bumpsteer, try to get your rack's pivot points even with the pivots of the a-arms and the tie rods and arms parallel. often it's easier to raise or lower the outer tie rod mounting height on the spindle to get there given there isnt much room for the rack itself. have you driven it yet? how's it feel?

it was almolst maxed out due to really stiff shocks.put another set on and it helped quite a bit.did not drive it yet, i will be done with the steering in a day or two. have to fab every thing and make some adjustments to the spindles. i must have had tunnel vision on the a-arms. what a bone head! oh ya and gusset the shock mounts, just wanted to see paint on it. i do have more though.

hey, that's pretty cool!
it should turn on a dime and give change. dont think i've ever seen a diff with an axial input. did you peek inside by any chance? does it have a planetary gearset? thx for the info

yes i did have it apart. at one point i only had 2 support bearings and it cuased some damage to some bronze bearings between the axel and they are replacable. and it does have a planetary set up.

a question-answerer on the page said it's a limited slip, not an open.
any truth to that? are there any worm gears inside it? (like a torsen or tru-trac car diff)?

I ran one of these way back when- it's a true differential, no limited slip, just a plain set of planetaries.Turn one wheel forward and the other turns opposite equally. The down fall of these units is that any hard off-road play causes the bolts to stretch and get loose & waller out the aluminum casing- also as jetasen74 stated that you have to have a VERY rigid bearing carrier to keep it from having wobble issues. Placement of the sprocket either has to go right at the posi unit or have bearing on both sides of it. This unit is ideal for a street kart that has really wide tires and a very short wheel base, allows for sharper turns with less wheel scrub.

dont laugh to hard at my pipe, and green is the only high heat paint i had
i dont think i will have another prob with the axel, i already did by not having enough support. i made sure it would not happen again. on another subject i built an exhuast pipe that i coppied the in side off of a motorcycle pipe

Your pipe looks fine(green isn't my color either!!) You may find that the all thread won't survive though- exhaust always needs to be supported from the engine- the two seperate parts moving differently will make something break,leak or stay loose. I lived this issue with many exhaust mod's and pipe failures/cracks or constant leaks- and broke exhaust studs.

say whats the big ideal.
 i have no clue where it came from. i think it was here when i moved in last year,are ya buyin that? thanks for the pos. feed back, it makes a guy feel good about his work. and thanks fof the fender idea, i have a 55gal drum left over from my mosquito business i gave up due to my distance from most of mt customers and had a realy slow 2 seasons. i just dont think its worth the time and money. i build,install, and service stationary mosquito misting systems. i did it for 5 years but no one is buyin any more and it seems to be a big hassel due to b**chin customer that want more for there money, (AND I AM HALF THE PRICE OF MY COMPEDITERS WITH PROMT SERVICE.THOSE JACK A**ES DONT EVEN SHOW UP MOST OF THE TIME) or they screw up the system and not fess up then it comes out of my pocket. any way sorry about that just venting. thanks again for the pos. feed back.

well good morning all. i had quite the morning,the neighbor woke us up around 5 frigin 30 cuase he or some a**hole that was riding his a** ran over his dog. good dog too. dobby (the dog) is in my shed until he gets home from work and we will bury him. it is not going to be fun as we live on a giant rock. it took me 45 min to dig a hole for my bunny (10 year old cat).
any way, back to the subject at hand. i am goin to put the yerf dog back together and if i have time cut out the fenders.wish me luck!

ok i almost have it put together, i gotta put on drivers side steering rod. had one on there and rolled it out to test steering and the drivers side (inside) hiem joint looked like it broke but it only had a few threads on it. i do have another, thank the lord. on a positive note it is very easy to turn the wheel, unlike it was the way before.

sorry about the dog, that always sucks.
i cant take fender credit; i got the idea from someone who used the same tub but made brackets and mounted them flange out. he has a page up somewhere and his look better. i went flange in so's i could use nice cheap zipties and i also figured having the flexible portion out in the impact zone made more sense. beware, the plastic gets pretty brittle with cooler temps.

well guys i took it for a test drive (but had to clean carb and make some adjustments), and with the new 10 tooth sprocket it is a big dif. it spins the tires in dirt or gravel and hauls a**. the new steering will take some getting use to. you have to turn the wheel more but is alot more stable. oh ya i almost killed myself part of the brake likage broke and i was doin about 30 easy had to pull in ditch and let the leafs stop me. but other than that it was a great ride.

ok if it is turned all of the way to one side it takes just about 1 and a 1/4 turnes to turn all of the way to the other. i would be greatfull to any suggestions you may have.i do have a grant gt steering wheel that has a larger od than the stock dog wheel. also i read yourpost about the clone choke sitch. mine did the same before i put on the mikuni carb. which realy woke it up.

if i'm gittin' it right, you wanna speed up your steering ratio so it's less turns lock to lock and more responsive?
only way i can think of w/o changing the pinion in the rack (or the entire r&p for another) (good luck there) is to move the tie rod/spindle pivot points inboard from where they are now. if it were me, i'd give it a few days of driving to see if you don't come to like the current setup; it should be much less twitchy than stock. that larger steer wheel isn't helping, but you know that already. the choke thing on mine isnt a problem, it just seems weird. soon as it fires i flip it off and it's all good.

ok it is realy smooth but like you said it is not as twitchy, i will take your advice and drive it for a few days and who knows i may like it. and if not i will move them in until i can afford a spider box rack and pinion. thank you sir.

Just for info.'s sake- my spiderbox rack with the added grooves is 1-1/4 turns too!!! IMO it's not too much- and I second the GOOD LUCK comment on finding something faster without paying well over a hundred bucks for the unit + connectors for the arms. I'd like to see your steering set-up too.

Just an idea for that exhaust. Why not add a bracket from the middle of the pipe, 45 degrees down to a bolt on the engine. That all thread won't hold up long. Remember triangles build strength.

i know it looks rough but it works realy well, turning the wheel is very easy and smooth un like the previous setup. the previuosnset up was fubard and the kingpin was bent all to heck. the rack and pinion was from an old drill press. the casing was cast so i built a box around it and a little at a time i welded them together, i heated up the cast berfore hand.both of my neighbors are wicked welders and they said as long as the cast is not too cold when welding it will do fine. and as for the brake linkage i am gonna gusset them to avoid this problem in the future.

I can verify your rack works as that's what I used on the 440 2-stroke Frankenbuggy!!!(Mine looks a little different though!) Nice work, glad it performed for you. It's a good pat on the back when it goes down the trail on it's own power and get's you back again!!

thanks, and it does make a guy feel pretty good when all of the hard work and advice from guys like you pays off. i am going to try a hill i had trouble with today before i regeared it. it is a step hill and you cant get a run at it, but the hill stands in the way of some potentially new trails.i think it is a dry (small)lake bed.

just saw your other vid on your s10.
i parted out my v8 s10 a few years ago. still have lots of good stuff left for sale. harwood 'glass cowl hood, real nice door panels, tilt column for floor shift, brand new in box tailgate, don hardy tri-Y headers (best fit of any header you can get for a v8 s truck), a 2 into 1 into 2 exhaust system in great shape using a big flowmaster and stainless flex couplers, custom aftermarket seat brackets, lots and lots more i cant think of at the moment. i also have a Syclone that's for sale, btw.

well i took the dog on some more trails with a few deep ruts that always have water in them, so i decided to brave them and went for it. it did great the water was almost to my bum.i need to do some thing different with the seating arrangment,need to make or come up with an idea for bucket seats like the spiderbox.

A pair of buckets is on my wish list too. I figure an extra lower frame bar from the mid-point of the floor widening out to about the middle of the rear tire hooked to an upper bar from the corner of the bar that the steering is mounted to would give enough room to make them work.

 i think with a bucket it repostion me and give a little more leg room. plus it would look cool as heck.
