Thread: 2005 RM250 help

Remove all Advertisements Put all the jetting back and bike still bogs I didnt actually go riding but worked on it at work(haha) and let it warm up for several minutes and rode it around the praking lot a bunch and when I let it idle all the way down and try to grab a handful major major bog, I think it might be worse with the richer jetting I put in it, 48 pilot, 172 main, 3rd clip on needle, air screw 1 1/2 out, and its about 60 here right...

I didn't have that problem when I put the hotrod crank in mine, it was really smooth. put a 50 and a 175 main and see what happens.

You mean to tell Me that You can't warm-up Your bike before You race.?......that Sucks.....My 04 just flutters until it warms up,,,,then it's perfect....Start's would be hard I bet....Maybe wrap an electric blanket around it ,,before the race........Just Kidding......good luck ........Dr.D.........
