okay i have an 03 440ex w/ hotcam, magnum revbox, duncan fatboy4 exhaust, edelbrock qwiksilver carb, k&N airfliter.
the bike has been cutting out at high revs after a while like it was leaning out or about to be out of gas. this has happened for the past month or so. well now all of a sudden it cuts in and out with lean pop and studders at just above 1/8 throttle same symptoms as before at high rev. but if i let it idle and buid up fuel itll be okay until i rev it out to 4th or 5th gear depending on how long it idles.
ive tried every setting on my carb lean to rich and tried the stock cdi box, new fuel after thorough cleansing and inspection of carb, petcock, tank, air filter, intake boots, new plug, oil&filter change, but still the same results.
obviously its leaning out but richening the carb doesnt help, too rich it barely even runs at all, when i go lean it runs better but pipes glow and it still cuts in the same fashion after revving it out a while. the needle in the carb is 25 e and i run about 7 clicks from lean and the bike was 3 clicks away from lean when i got it.
the only thing ive done to the bike is add rev box gas and oil. so there is nothing i did to mess it up other than maybe ride it hard.
after 3 6-8 hour night of tuning and plug readings still no fix.
does anyone know of issues with the edelbrock quicksilver that causes this, i dont seem to succking air cause it does it with air filter on or off. the bike has always been fine until last month it started cutting out at high revs. ive always been mechanically inclined and all the people i know including some experts just say its too lean but thats not the case with carb setting.
i checked vavles and they seem to be within range. like i said the bike will be fine when i start it and put it or cruise it but when i get out on it its like the carb drains itself for gas but the fuel line never emptys or show signs of fuel being needed.
im clueless at this point please help me
