Picked up a Spiderbox a few months ago and am doing a 420cc swap on it. My kids have Go Karts and I wanted one that I could ride around in with my youngest daughter so her and I are building this one for us. Sons is a Streaker 8 and my oldest daughter has the Yerf-dog 3002. Cut up the Swing arm. The 150cc engine that came with it was is bad shape and the 420cc was on sale. Going to go with a heavier shock in the rear if anyone has suggestions on what a good shock for the rear is that will give me some extra lift would be awesome. I did a quick mockup of the engine yesterday and today I tore down the front bulkhead to get ready for all the new BDX parts that I ordered. Getting the works. going with a 22X11-8's in the rear and a 19x7-8's in the front. Also getting the Steering rack sent out for extra teeth cut into the rack from buggy depot.

This Go Karts for My 6 year old and me to keep up with my older 2 kids, She wants to paint it red with flames(we'll see how that goes). I'm just enjoying building something playing with the welder.

parts on order are:
Deluxe Flexpruf Steel Step-Down Axle - 1" to 3/4" (Standard) Size*: 42''
#40 Sprocket 60T with 1" bore

Cool build, wonder how that 420 will perform.

Fink · #3 02-17-2018, 09:50 PM

I have high hopes for it. Not looking to a speed machine. Pit vehicle for when we go to the track and something that can pull my dads mustang around the track during test and tunes. Just waiting on some warmer weather so I can start working in the garage again.

Got back from vacation and cranked away all day on the swing arm while I'm waiting on parts from BDX and Gopowersports. Made some pretty good progress and am happy with the results so far. Can't wait to finish this one up because I think my next buggy is going to have a motorcycle engine. 250 ninja or a GS500. Having a blast fabricating this stuff

Fink · #5 03-01-2018, 06:46 AM

Got the swing arm 90% completed. Got new bearings from Gopowersports and 2 pillow bearings for supporting the middle of the axle under the engine. New brake master cylinder supply line are ready to install. New wheels and tires are arriving today. The Rears are only temporary because I'm going to a larger size, I got 18x9.5x8's rears and fronts of 19x8x7 new setup will be 22x10x10 and 19x8x7. Old new fronts will go on my daughters Kart. Which I'm still trying to upgrade to another spiderbox or hammerhead 150. really not a fan of the 3002 model.

I also posted up a weld picture because... Why not. I paid $78 for this welder from Harbor freight and for a complete welding noob I think I'm doing pretty dam good. Although Before my construction accident I welded plastic pipe so I'm not a complete noob.

Fink · #6 03-01-2018, 05:17 PM

Got the tires in today. The Rears are alot smaller than I thought they would be so I'm probably going to swap them on my sons go kart and get a set of 22x10x10s. Just waiting on the BDX front end stuff and I finish this puppy up. Going to weld in gussets and paint the frame this sunday.

Fink · #7 03-07-2018, 04:45 PM

Got an update on my front end and I can't wait to install this monster.

Fink · #8 03-29-2018, 02:43 PM

quick up date. Got the BDX front end installed. Just waiting on the Wheel spacers and modified Steering rack and the front end will be done. In other news I Modified my sons 3002 from a 2 seater to a 1 seater.

Fink · #9 05-17-2018, 08:02 PM

The 420 performs amazing for the record. Got a ton done just needs paint now. Had it out in the mud and offroading. It's a blast.

Helmet is here, and I installed 4 point harnesses. Thanks for your concern and its been fixed. You don't sound Offensive you sound like someone that cares and we need more of that in today's society so thank you. Next time you see a video you will see me with a helmet and a harness

Fink · #12 05-21-2018, 08:03 AM

Added Harnesses and welded in the brackets. Started slowly painting what I could before i have to tear it apart to get everything painted. Then I have to tear down the Hammerhead and strip and paint that.

OLDKID · #13 05-21-2018, 08:33 PM

Bad To The Bone !

Fink · #14 05-21-2018, 08:58 PM

Getting there. Can't wait to be done with Paint.

Fink · #15 05-23-2018, 08:09 AM

Paint is done!... For one of them now I get to pain the Hammerhead which looks Infinitly harder with all the wiring harnesses and cables.

Daughter is happy though

Fink · #16 05-23-2018, 01:48 PM

Nearly 6 months later it’s complete for my first build. Learning welding in the fly and not knowing anything about Go Karts I’d say I did alright. And am now addicted.

Fink · #17 05-23-2018, 01:55 PM

Before December 8th 2017

After May 23rd 2018

Very nice! How does this animal perform?
Does it have some low end torque?
What is your estimated top speed?
I'm re building a busted spiderbox and using the same gears and tires.

Fink · #19 07-11-2018, 05:53 PM

Lots of low end torque great for hills and mud. Flat out it does about 33-35mph. The upgraded steering rack makes it much more manageable for tighter turns.

That sound pretty good, I wouldnt want to go much faster than that. Where did. You get an upgraded steering rack? I was thinking of having some more grooves cut in at a machine shop.
