Any help would be nice... my bike recently is running really rough in low rpm but when you get up to last 5-6k it runs like normal. What should I do to fix this? in low rpm the engine just sounds like it is sputtering...

thanks

more background info needed... has the bike been sitting? sounds like carbs might need cleaned, and or syncronised. but it could be about a million things.

Clean the plugs and check that the plug "hat" and lead connections are ok. Sounds like it's running on 3 cylinders on low revs and the 4th join the rest as the revs go up. Easy to spot by checking if the exhaust down pipes all heat up as you start a cold engine and let it idle.

check the valve gap
synch the carbs
new plugs
weak battery, charge or replace it, tighten all terminals
air filter dirty, check, clean, replace it
