Moderator Airhead Posted January 7, 2014 Moderator Share Posted January 7, 2014 one of the screw (the big one) is not to be set 1 1/2 turns out at all, that one is the throttle stop screw, you screw it in clockwise until you have a sensible idle rpm speed Link to comment Share on other sites More sharing options...

Moderator DirtyDT Posted January 8, 2014 Moderator Share Posted January 8, 2014 It is always hard to diagnose over the interweb so the most common issues are checked first and that allows everyone to know what has been checked. As with some of the suggestions so far, the normal cause of these symptoms is a blocked pilot jet. Have you checked that the pilot jet is the right size? I am guessing but have you cleaned the needle jet and set the float height correctly? As with airhead's comments, the mixture screw (normally small brass slotted) should be 1 1/2 turns out and the larger, often knarled screw should be turned in until you get a decent rollover. My comment on trying it with the fuel.cap off is because ; as it uses fuel, the tank needs to suck in air or you get a vacuum. So in order of things to try - in my opinion; Fuel cap off Take off the carb check the jets again for cleanliness and sizes and reassemble checking the float height. Ideally I would also carb clean all of the carb passageways by either using a carb cleaner or boiling in an old saucepan. I would also check the floats for holes. Reset the carb as per previous advice. If possible put a new spark plug in it and check the plug cap for tightness. Further to that I would also look at the airbox. Is it running a standard airbox and filter? Is the airbox clean? Is the filter clear and oiled? That should keep you busy for a while. Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 8, 2014 Author Share Posted January 8, 2014 Yeah i no what you mean its hard without seeing the problem but up to now The jet is defiantly clean iv blastedcarb cleaner through all holes were jets fit in the float has no holes init iv checked that and its fitted in correctly with the rocket valve so im assuming thats set correctly as i dnt no how to adjust it lol but the air filter is a pipercross filter though not a standard 1 this was in the bike wen i got it but i will clean it out and work through this list and get back to you cheers guys Link to comment Share on other sites More sharing options...

Hitchen187 Posted January 22, 2014 Author Share Posted January 22, 2014 Yeah i thought that also could it be a slight air leak were the accelerator cable screws into top of carb mine is a flat slide type Link to comment Share on other sites More sharing options...
dt502001 Posted January 22, 2014 Share Posted January 22, 2014 Ok your making this difficult you have to many different post about this running problem. Copy and past them all into 1 thread to follow and keep it as 1,trying to follow and narrow down the problem the way you jump around is like a retard in a room full of bouncey balls,oo look there's one oh a blue one no a red one, I like yellow??? Not saying your a retard but to fix a problem of any kind you need a methodic way of eliminating the varriables and come to a finnal conclusion.First you were on about reeds and now your jumping at straws about a leak in the top of the carb 3 Link to comment Share on other sites More sharing options...
