Yerf Dog Spiderbox manual
 

I just purchased a spiderbox and need a service manual, does anybody know where I could purchase one

Not sure anybody sells one but you google it you can find it online for free. I can't post the link here or I would

I’ve tried with no success I’ll try again thanks

Is there something in particular your needing to find? The original yerfdog service manual pertained mostly to the motor it's self with very little info on the chassis. It listed part numbers for chassis components but these numbers are obsolete. The motor is a standard 157QMJ so any service manual pertaining to the gy6 150 cc will cover it. A forum supporting vender, Buggy Depot carries some chassis upgrades along with all motor parts. BMI karts bought out the remaining yerfdog inventory when the company folded so they have some OEM chassis parts but when their inventory is depleted, it's history.
There are a lot of yerfdog owners on this forum with tons of experience so if you have any questions these folks will help.

I'll say I have only dealt with BMI once and they burned me. I'd also suggest Buggy Depot for good parts.

I'm looking for a wiring diagram, some of wires have been cut. I need to fix the wiring to see if it'll start.

There is a size limit for uploads, send me an email address and I'll forward.

I downloaded it from one of the suppliers, I'm thinking CHP?
