I can't believe it lasted this long either! Big thumbs up to the designers of the chassis, but we all have known this for a long time, that's why this buggy has warranted the modifications of those that own them. As I stated before- weight capacity played a big role in the failure ,of course dropping off a huge hill wasn't anticipated by the designers either. The swing arm didn't sustain any damage that I can see, I'm guessing that a more expensive set of shocks could have held the carnage off a little longer, but it was just a matter of time. I'll rebuild it and put the fun machine back out in the trails. Of course I'll be looking to beef up the materials.

My Blade has had no cracks and has been driven in areas I thought I'd never get back to camp in one piece. Weather a HH or Carter or Kinroad everyone I ride with who have those buggies have all welded the carrier many times. I am a huge believer in shocks which these buggies lack. I have the Works shocks on mine and believe is the reason my frame has not cracked. Not to mention the better handling and ride by 300%.

I figured I'd take a few more pic's of the spiderbox with everything removed to show the damage better. This is one of the only areas on the buggy that didn't/hasn't needed some modification. These bars that are bent should be straight!! You can see how bad they are if you line them up with the rear rack. The fun begins now that it's disassembled, it will be an easy enough fix as it turns out. If I feel up to it I may make a new swingarm too since this one has had many mod's done to it since it's original installation (2011) with the Honda TRX200SX replacement in leu of the Howhit GY6 150(which is still a great engine). I'm still very happy with the decision to do the engine swap, as it fit's so well. I'm still in awe with how much power these little engines have and the reliability of them. I wish they weren't so HARD to find these days @ an affordable price so others could have the choice on an alternative power plant for these buggies and other kart projects. I'm sure everyone on this forum knows it's my powerplant of choice!!

I got it back together with an improvement.The play time was short lived though-RAIN. I had the original roll cage from the Spiderbox laying around and figured it could be used for something so I built well needed nerf bars and rear fenders that may last awhile when loaded with mud. They bolt on and are incredibly stout! I've always been concerned about the kids snapping/bending a rear tire when navigating between some off the trees as the front is narrower than the rear. Sorry about the pic's in night vision- tried to get pic's before the buggy got muddy.

Looks good, nice job.

Stopped raining! I took it for a short cruise to test the repair to the rear of the chassis, I also added some other curved supports at the top rear bar behind the seats to hopefully re-enforce/transfer the load from the shocks. I put a new set of Harley (sportster) shocks I got in a trade on the rear to see how they perform-seems cushy with good stability when turning hard. Time/abuse will tell! The nerf bars definitely made the whole buggy seem more solid. I'll shoot some video of my daughter running it thru the paces for confirmation of not bottoming out or lifting of the rear wheels and stability of the rear fenders.

Well my daughter decided to over drive the Spiderbox a little:rofl: She forgot she didn't have a passenger as a counter weight. No harm done.

I take it she was OK? I just picked up a new toy, a 2008 Jolaris. It is a Joyner 250cc with a Polaris 500 HO engine bored and stroked making it a 600+cc . Haven't driven it much but it is a beast.I just need some bigger brakes since the braking is lacking. Had it to just about 60 mph but had to let off w cause it got squirrely.

She's fine- it just freaked her out! That Jolaris sounds like a monster and deserves some drive time & a good shake down from a work-a-holic, take a minute with this nice weather and go have some fun.
My daughter was cheezing when she got to take the Spiderbox out for a speed run on the street(no traffic-no school) with the GPS- she got it up to 50mph before she ran out of street and squawled the tires, so it will probably go a couple of mph's more with a longer run. She had just shifted into 5th before sliding to a stop- she doesn't get to go on the street very often where it's smooth and flat. More fun to be had now that we'll have some dry weather for a change!
Thanx for the compliment EVILWS6

I'm in Fl. by Tampa. I have a running yerfdog spiderbox all original. I would like to clean up the wiring a little before I try to sell it. Do you have any pics of the original howit wiring by chance?

metalstudman1 04-05-2020 06:48 PM

I'm actually the worst person to ask since mine hasn't had a GY6 in it for years. Possibly someone else on the forum could help- try making a new post asking for pic's of the stock wiring. Sorry I couldn't be of more help

SYCARMS 04-18-2020 05:04 PM

A wire schematic for the yerf has been posted on here in the past. Try doing a search
