Yamaha FZR 600 buggy

[bullrider700]

I am thinking of buying this. Look pretty cool and have the right price?

Mint condition Gokart, it has all new parts and is VERY FAST!

Yamaha FZR600 engine (less than 2 hours on new engine)
Full Yoshimura exhaust including header
Vance and Hines racing CDI box
New clutch
New tires
New drive chain and sprockets
New brakes
Gauges
Built out of 1 1/4 inch DOM (roll cage metal tubing, STRONG)
New 5 point harness

It is ready to go, also i have a large amount of extra parts to go with it including (extra carbs, extra new clutch, extra engine with covers and all, extra starter, radiator dash, ect..)

$2500 OBO (Im getting it for $1900)

[bullrider700]

He also says he has the parts to put reverse on it but its going to take some creativity. What does he mean by creativity? hahaha

[bullrider700]

Also, any idea on how to make this a 2 seater?

[roysheepdog]

Why would someone build this and only ride it for two hours?
should be fun

[donrichard]

I can only imagine the rooster tail it makes .

[metalstudman1]

So bullrider700 did you buy it?
Got any other pic's?
The FZR600 is a great engine with lots of HP and parts are plentiful- but without reverse it's going to be a pain in the butt!!!!
Making this into a 2 seater will require "some fabricating"- moving the pedals, steering wheel, shifter, seat base, seat belts, ect.......

[bullrider700]

Yes I bought all of it for $1,900! Pretty sweet buggy! Going to weld a drive sprocket to a starter motor and put it on a lever that I'll be able to drop on the chain. What do y'all think of that idea? I'll post pics later

[metalstudman1]

Got any video? I'd love to see pic's from all angles of this buggy- The starter for reverse has been done before so it's a proven solution- the lever machanism sounds feasible!!

[bullrider700]

Ok I'll be back to my garage Thursday or Friday and I'll see if I can get some videos and pics posted for ya

[bullrider700]

If you would like any more pics let me know! Probably going to need help rigging this redneck reverse up, so if any of you have any opinions let me know.

[bullrider700]

I will also post a video of all around the buggy if you want when I get home Thursday or Friday.

[roysheepdog]

for reverse use a flex plate and starter from a 350 chevy.you can get a 13'' flex plate for under $50 new.

[bullrider700]

You dont think the starter from a FZR600 engine would work? I have read about the flex plate idea. Should I bolt the flex plate to my rear sprocket?

[metalstudman1]

I doubt the FZR starter will have enough torque- usually need a high torque one like for hot rods.Your trying to move several hundred pounds!!!!not 4 pistons!!!! They are pretty cheap (around$100.)use less voltage and withstand longer engagement cycles without burning up, also they provide a bolting flange where the FZR starter doesn't. Yes to the question about the flex plate, it can be bolted to the sprocket or stand alone with a stiff carrier.- you set it up just like it would be on the vehical, when powered up it engages till power is removed, usually a momentary button or switch.
Is the steering geared for quick ratio? How does it ride/handle?

[bullrider700]

I have not got to ride it very much so I am not sure on the handling. I work away from home and come back on the weekends, so Ill fully test it out this weekend for sure! Thanks for the starter info! The guy that sold it to me told me I would probably have to put a steering stabalizer on it because when it gets going fast you better hold on to the steering wheel tight haha. Was thinking about getting installing a rancho stabilizer shock

[bullrider700]

I kind of bought this buggy for a learning experience. I do not have any experirence with these things. Im a racing 4 wheeler guy. So any input would be appreciated!

[bullrider700]

Im also going to have to put a chain tensioner on it for off road use. the middle sprocket is bolted to the frame so the chain hops off the sprocket when it gets bumpy. know of a cheap place to get one that I could put this sprocket I have on?

[metalstudman1]

I just posted about this issue: http://www.buggymasters.com/forum/sh...ad.php?t=1602- Post #69 and a vid of it working- http://www.youtube.com/watch?v=d2z8ATY7vBE
This design has worked well so far- I've been unable to find a cheap tensioner!!!that does it's job in the rough. Your primary issue is different than mine- your chain get's slack as the swingarm moves. The swingarm arc of movement doesn't match the drive sprocket on the engines arc. The bolted sprocket at the bottom of the chassis needs to move with the chain under spring pressure. Figure out how to un-bolt it , give it a pivot movement with a spring holding pressure on the chain. Sorry this isn't really clear but it has a spring(upper left corner) hanging from above.

It appears they utilized the chain drive on the steering wheel to reduce the turning radius of the wheel- quick steer!!! The stabilizer if you could hook it up would only stiffen the wheel- make you use more effort,(you need a drag link for a stabilizer-you don't have one) since buggies are very light they react to bumps very differently than a car. Would love to see a video if you have the means to make one of this buggy on the move. This buggy looks good and well thought out- I'd like to see how the very short swingarm reacts on the bumps since it has no weight on it.

[roysheepdog]

I would like to see some good pic of the front end,wheels and how it all put together.Not knocking the buggy but by the way you said you have to hold on to the wheel tight, it may be built wrong.that is the hardest part of building a buggy(wheel and steering geometry)to get right.Many people build every thing well and get that part wrong.

Like stud man said with the chain the swing arm pivot is in the wrong place according to the sprocket.They have to pivot in the same place or it will never be right, chain tensioners with that much h.p dont last very long unless built very well.
One easy way to fix it so you can get some seat time until a better fix is limit straps to keep the swing arm from moving as much so the chain does not get loose.

With reverse a high torque starter would be best but ive seen a lot of part house starters work well.1975 SB chevy starter is still around $35
good luck

[bullrider700]

Ill post some more pics for you Roy on Thursday or Friday so you can tell me if there is something wrong with the steering. THANKS!

I was thinking about getting one of these for the tensioner. I guess Ill choose one once I gethome and see how its set up?

http://www.monstercraftsman.com/categories/Tensioners/

I will also take some video for you Stud. THANKS!

I have also done some reading on the reverse systems. I think Im going to try a diesel starter with a flexplate. I guess by bolting the flexplate to the rear sprocket it wont hurt the starter???

[bullrider700]

Also, If I was to buy a welder to work on buggies what would my cheapest route be?

[roysheepdog]

I havent seen the flexplate bolted to the sprocket.but if there is room for it i guess it would be ok, the starter needs room on both sides of the flexplate,I would use a weld on hub or something like that.
With a diesel starter you may have to have a flexplate from the same truck so the teeth line up.How big is that going to be?If its to big it will hit on every thing.
the sbc flexplate 153t is 12 3/4'' so it should be smaller than the sprocket.

As far as a welder,the cheep ones are not the way to go(imo).I have 20 years in fab work
and i would not even use one to tack with.A lot of people use the ones that dont use a gas shield and make it hold,but they are not rated for structural welding(it will say so on the wire role).When your life is being held by the weld,its worth a little extra money to get a better welder.
Ive seen welds break that were made by people that weld 65 hours a week and used $2500 welders.I would not trust my life on a cheep welder.just what ive seen and my opinion.

[bullrider700]

Thanks! I'll look into the starter and flexplate some more. Yeah I guess I'll just wait to get a welder until I start doing more major fab work. For now I'll just get a buddy to do the small things. My main concern right now is getting a good chain tensioner so I can get this thing off road!

[bullrider700]

Buggy runs great!!!! Had a lot of fun on it today! Nothing wrong with the steering at all! I'll post videos tomorrow or Monday!

[bullrider700]

I need to put that chain tensioner on it because the cahin came off while I was doing donuts!

[bullrider700]

http://www.monstercraftsman.com/categories/Tensioners/

Now that you can see how its set up. Which tensioner on the above link do you think I should order. Or is there another place to get one that anyone can recommend?

[roysheepdog]

i would the one with a sprocket.

[metalstudman1]

Will the bolt on one fit where the solid one that came with the buggy fit?

[bullrider700]

Im not sure I didnt mes with it last weekend. Im having a buddy go to my house tomorrow and tell me which one I should get, since Im out of town for work.

[bullrider700]

Does anyone know if putting a drive chain guide, like off of a dirt bike in my chain guard and running the chain through it would help? If so, do you know where I can get one that will hold up?

I'd think this one would work better than the 1st one you listed as the chain is long- He just needs to get it out where it can do some good.

[bullrider700]

http://hyperracing.com/pages/home/pr...product=08-800

or this?

[metalstudman1]

The one from Hyper works great, but the wheels wear really fast (they did for me on "my different type of buggy")

[BuggyMaster]

that is one hell of a good start for a fun toy. Just work the kinks out and you are good to go! I think I would definately have to find some way to make that a two seater!
