last week my bike started to bog down and want to die during the first 1/8-1/4 turn of the throttle.. ive had similar problems which turned out to be gummed up carbs causing ristricted movement of the needle piston.
so i pulled the cards and gave them a good cleaning a few days ago.. problem still there!
so then i tried manually opening each carb to see if both sides of the engine were running the same..
the right side sounds and runs excellent.. but when i lift up on the left side throttle attachment, it sounds horrible. if i lift up very slowly it doesnt really studder, but doesnt sound good.. if i lift up fast itll really bog down and the engine will shut off..
i adjusted timing two weeks ago so i dont think that is the problem, although it could be if something migrated. i do not currently have a timing gun to check..
now to my suspicion... me and a buddy rebuilt the top end two weeks ago which has lead to a pretty nasty oil leak.. it is leaking out from where the points attach to the engine.. he seems to think that the leak is due to a bad cam seal..
i dont know if a bad cam seal on the left side could lead to piss-poor performance on that side as well.. but it is the only thing i can think of..
does anybody have any ideas?
