I have looked at the cheap operators manual and model spec sheet that came with my machine and I can't find the peak RPM range for my stock 2003 800 EFI Artioc Cat engine. I have kept my stock mountain clutch wieght in the the machine and when I travel at low elevations - I don't want to over rev the engine. I was told that too much RPM's over will blow the crank real easy. I went to Argyl MS and they tried to look it up and they couldn't find any info. Any Advice ?
