February 16, 200818 yr can any one help i have a 2007 Cabestany Replica, it is hunting when ticking over and will then stop, when reved from ticking over it pinks a bit, above 1/4 throttle it is running OK
February 16, 200818 yr Ah the caby rep and carb probs, try cleaning the pilot jet (and main whilst your at it) or go a size larger on the pilot and check your float height Edited February 16, 200818 yr by The Addict
February 16, 200818 yr Have you got the correct fuel in?Normal unleaded can cause pinking,also a dodgy plug can sometimes cause this.Change the plug and check the fuel octane. As for the tick over,i would give the carb a good clean.The shercos are a bit prone to getting crap in the air filter.I have an 04,filter alway gets mucky.
February 16, 200818 yr Author Ah the caby rep and carb probs, try cleaning the pilot jet (main whilst your at it) or go a size larger on the pilot and check your float height Thanks for your reply i have cleaned the carb thre times with an air line, what size of pilot would you use and how do you check the float height
February 17, 200818 yr Not sure what the Caby came with, but usually around 40-45 on the pilot jet I would think. Ask Addict what he was running? Be sure the fuel tank is venting properly, there is no water condensation in it, the bowl vent is clear(side of carb) and not only clean the jet, but remove mix screw and blow through low speed passages as these must be perfectly clean! Hope that helps!
February 17, 200818 yr what size of pilot would you use and how do you check the float height The absolute size doesn't matter. One size up from what you have in the carb already should fix it. An engine that surges is typically running a bit lean. Fairly common on a properly jetted bike once the weather gets colder. I try to carry +/- two sizes of main and pilot jets in my tool box. Just ordered a set for the new Beta since I have Mikuni jets in the toolbox but none for the Keihin. A good $12 investment.
February 17, 200818 yr While you have the carb off check that the breather hose on the exhaust side of the carb is in good shape as it can get close to the hot exhaust if the carb is twisted a little. Better yet drill out (carefully) the same vent on the near side of the carb, but attach a short hose as the vent is horizontal and easy to get c**p in the carb without the hose fitted.
February 17, 200818 yr Author thankyou for your replys today i changed the pilot jet from a 42 to a 45 and it has helped i was going to buy a 48 and try it
February 18, 200818 yr i have fitted new plug and using 97 octane fuel The minimun octane is 98,In my experiance,lower octanes dont always make older bikes pink,but new engines benefit more from the correct octane.The higher the octane,the less chance of the engine pinking.You can 99 now i think.
