Moderator Airhead Posted January 23, 2014 Moderator Share Posted January 23, 2014 Damnn this is an awkward bastard bike, yeah change the plug for a new one thats always a good bet. So it ran ok for a while...no probs at all? Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 Yeah had 3 or 4 short runs without cutting out and i was opening it up full revs the only slight issue was a high idle at 3-4k it cut out when i put choke on but i assumed that was normal with engine being warm but wen bike was idling high i tried to adjust the idle screw and it didnt really change much it was either high idle or wen i adjusted screw out at small alterations it just dropped to almost cutting out and i had to flick choke back on for a second for it to keep running if you understand what i mean iv just ordered a new standard air filter aswell just to eliminate that as an issue Link to comment Share on other sites More sharing options...
blackhat250 Posted January 24, 2014 Share Posted January 24, 2014 I take it that was the idle screw , you backed off" large knurled edge, not the air screw[ small cross head ] ? As the idle screw just raises and drops the slide. a small amount should not cause engine to die, Link to comment Share on other sites More sharing options...
dt502001 Posted January 24, 2014 Share Posted January 24, 2014 Now you have a air leak somewhere possible causes carb not tight ,reed valve not sealed,intake cracked, left crank seal. edit Or what blackhat said just read it. Link to comment Share on other sites More sharing options...

Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 I havent checked the security or condition of the expansion bottle that goes in the inlet manifold either so ill do that aswell Link to comment Share on other sites More sharing options...
blackhat250 Posted January 24, 2014 Share Posted January 24, 2014 Yeh" spray behind the flywheel with an excelarent . [ WD/ Brake cleaner/ carb cleaner/ ] while bikes running " if the seal is worn / hard. it will pull excelarent into crankcase, and revs will increase , was the bike unused for a spell , ? The other seal R/H. pulls gear oil thru [ when worn] and smokes heavily, Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 24, 2014 Author Share Posted January 24, 2014 Ok ill check that iv noticed that it looks asif its been spitting oil out of the exhaust maniflod and on to the numberplate at back you think this is crankcase seal issue then Link to comment Share on other sites More sharing options...
