Im running 32:1 and i have stock jets but i got a fmf powercore 2 silencer and i live in VA and it not really high elevation and the heat is mild it is around 80 in the summer but if i had an air leak like he said then where should i be looking for it at. BTW i have been having a problem getting my head pipe to stop leaking where it mounts up i have replaced the gasket but it still leaks from time to time.
And it really all started when i hit a mud hole because i hadnt been riding for no longer than 20 minutes and when i hit the water thats when all hell broke loose and i no that all my gaskets are good because i had to replace all of them because the person that had this atv before me apparently thought that gaskets werent needed and put that liquid gasket on everything.
