I have a 02 426 with Rekluse clutch 158 mj and stock pj, air screw out 2 turns and when I go down steep hills in gear it will stall. I have also done the BK Mod and run a PowerNow. The installed gap in OK on the Rekluse. I ride at 1500 feet up to 4800 feet. I have turned up the idle and it will still stall. If I turn up the idle too high then the bike will go down hill a little faster than I want it too. Do I have a clutch issue or a carb issue? Thanks for any advice.
