... does anybody think it could have somethign to due with the oil breather line to the carb. i know on my bike after riding for awhile the oil starts building up on the filter then starts dripping down. possibly could be gettign somewhere it shouldnt. is there any way to prevent this or reroute the line somewhere else
I added another line where the plug is on the cam cover (opposite the gen) and ran a hose down under the engine. The oil mist blows out there instead of into the air cleaner. As Jason's Sporty said, could be an electrical problem, but unless it's been changed, you should have electronic ignition, not points. I doubt the oil blowby is causing your problem, unless someone has plumbed the hose into the carb mouth - but then you'd probably see some smoke if it was bad enough to cause bad running.
I never wanted a Harley, but I always wanted a Sportster.
If it ain't broke, don't fix it (especially if you don't know what you're doing). Most Sportster problems are owner-induced.
