Gemeiner Posted May 23, 2015 Report Share Posted May 23, 2015 hey guys, ive been noticing a strange buzzing sound when im off the throttle sometimes. one time my fuel line popped off and my engine was making that sound. but its only when im off the throttle and coasting usually. sometimes it gets kinda loud but if I shift up and lower the rpms a lot, it usually goes away. but my rpms weren't abnormally high when it did that. just kinda makes a bzzzzzzzz sound. Is my pilot too lean or something? the next size up (30) seems too big and I cant start my bike with it. I cleaned it up a lot with the air screw but its still there. kinda strange.

98_sheester Posted May 23, 2015 Report Share Posted May 23, 2015 Kick it over and press on your lower exhaust springs they might just be vibrating against the pipe Quote Link to comment Share on other sites More sharing options...

hoppedupandcutdown Posted May 23, 2015 Report Share Posted May 23, 2015 sounds like you have something vibrating loose and sucking air. Carb top maybe? Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted May 23, 2015 Author Report Share Posted May 23, 2015 the whole motor sounds like hair clippers when it does it. it goes bzzzzzzz bzzzzzzzzzzzzzz. kinda strange. worried ill damage it haha Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted May 23, 2015 Author Report Share Posted May 23, 2015 ya possibly an air leak huh Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted May 23, 2015 Author Report Share Posted May 23, 2015 the choke tube btw the carbs is kinda short. maybe I should get a longer piece. might not be on enough. Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted May 24, 2015 Author Report Share Posted May 24, 2015 longer tube didn't work. I don't think I have an air leak. ill have to spritz water or something and see. it seems to do it when I let off the throttle and coast or if I give it a little gas but don't hit the powerband. that's what made me thing pilot jet, but the next size up seemed too big. when I rode it just now, it started doing it the worst its ever done before, and I completely lost power, just bzzzzzz every time I gave it gas. It slowed down then it died. could it be the CDI? I have no experience there.. I thought it was dead but I was able to start it again.

hoppedupandcutdown Posted May 24, 2015 Report Share Posted May 24, 2015 I'm gonna go out on a limb here and say not fuel line, not pilot, not CDI, look things over real good for something vibrating loose. I had a flywheel nut back off a hit the aluminum stator cover a make a strange noise, didn't run it long though. Quote Link to comment Share on other sites More sharing options...

Gemeiner Posted May 24, 2015 Author Report Share Posted May 24, 2015 ok ill look everything over. hopefully ill find something. just sounds exactly the same as if you run it with the fuel off and it eventually runs out of fuel. same noise. couldn't be the fuel line, youre right. because it only does it if im off throttle. but the fact that I can go full bore for long durations means its getting fuel. the fact that it does it only when im off throttle or around 1/4 kinda makes me think that the pilot might be off. idk lol. it kinda idles high and fast too idk if its related. weird though.

do-work-son Posted May 24, 2015 Report Share Posted May 24, 2015 Maybe broke a cracked reed? Quote Link to comment Share on other sites More sharing options...
Gemeiner Posted May 28, 2015 Author Report Share Posted May 28, 2015 you know what? I think its my carb needles. I think theyre too lean. that's why it does is when I let off the throttle. I might have put them up a notch when I rejetted and I also went down a jet size.... stupid of me, I should've played it safe and gone rich. means itd be plugging the pilot too much when im cruising.
