Is that thing heavy for you to lug around? I reckon I'd pull myself over if I tried to pick one of them from a wheel chair
I'm curious to see if the chassis holds up for you. I've heard people say that aluminium front arms don't give so it breaks the chassis if you hit something hard enough. Under the front skid is a couple of screws which form a perforated line to snap.
Of course, they might be just driving like dic...I mean like me.
What clutch are you running? If you don't have one get a ceramic clutch. They are expensive but they last that much longer so the cost works out abuot the same in the long run. The advantages are not having to change the clutch so often and when it does die it is much less likely to overheat the shaft and bearings. I say this because a stroked motor with pipes is going to be a lot of grunt and you will go through the clutches fairly quickly.
