Ok Guys,first thing is he won his class both motos....awesome.... Second thing is, his DRR didn't do well, I need some help, after practice, we went to his backup quad, his modded Predator 50, it ran awesome, now back to his DRR50, Tuesday he practiced for 30 minutes and it ran flawlessly, today during practice, it wouldn't even pull the hills and seemed not to rev hardley at all, also it seems that once in a while it acts like it jumps a tooth or something, it must be internal as the chain and sprockets are fine, we have a Keihen PE20 carb with a Uni filter on it and are about 1600 feet above sea level, I just don't understand how it can run great one day and 4or 5 days later it runs terrible, any help will be greatly appreciated.How hard is it to change the internal gear to a hardened one, maybe that is the jumping, I am not sure..By the way, he had a blast and is hooked, his trophy is almost as big as he is....Thanks Guys......

what type of clutch components are you running? the torsion springs and rollers in some batches have worn very fast and caused these issues before(ie worn torsion or flat spotted rollers), The gear jumping is probably the tranny if your rider has landed on the gas a few times. They don't "jump" teeth though, they are just kicking past where a tooth has broken off and will break off the other teeth. The hardended gear won't keep them from breaking if they land on the gas, there are a few options for this though. I am just guessing here from your explanation,but you can PM me if you need more direct help.

similiar thing happened to us 2 weeks ago.. it wound up that the air filter
was not sealed right and sucked air in to the carb making it bog on the bottom end...

Thanks Jim, I will check that as well,I pulled all the clutches apart and found nothing, so I am kinda at a loss, I will try everything that anyone suggests at this point, I am thinking carb,but open to other thoughts as well.Kurt
