How many race mods should I do??
I am planning on racing at Atco MX in NJ this Spring with my 9 year old son in the CVT Prod 70 & 90cc classes and my inquiry is this: He has ridden his DRR DRX 90 "limited" version quad for one season at MX tracks and ridden 2 years on another machine prior to that. My question is how much motor mods should I do in the first year of racing. Should I have porting done to the "stock" cylinder & head, tune the clutch a little more, maybe the DRR pipe, maybe change carbs or do I go ahead and get an aftermarket cylinder & head, pipe, full clutch prep, electrics etc.?? The machines will be stock length Elkas (full tuneability) so we have a good degree of tuning the chassis.
My thought is to do some small things initially, see if he likes the racing, and let him grow into the speed until such time he needs "more speed"? Or do I spend the addt. $$ right out of the box?? One more consideration, I understand racing and the inherent costs associated with it and am willing to spend some, but I do have a budget in mind to some degree. IOW, need to spend the $$ most wisely considering it is year one in the racing scene. Any help is much appreciated.
