wesw Posted October 19, 2008 Report Share Posted October 19, 2008 your bog could be from lack of fuel. stock cylinder jugs that ive seen or played with a 45 pilot was awfully lean a cub i could see but stock jugs. but it could be your electrical stuff also. sounds like a pain in the ass for sure.

jbooker82 Posted October 20, 2008 Report Share Posted October 20, 2008 If the other stator didnt fix it I would say your rich. Ripping down the road real quick doenst really get everything warmed up. Trail riding puts more of a load on it and it warms up. Less air because it is warmed up with the same amount of fuel. It warms up and richens up.

Badapwned Posted October 23, 2008 Report Share Posted October 23, 2008 Same exact shit happend to mine. What I found out was the spark was dieng, I was getting intermittent spark just like you suspect. I think I fixed it last night, when I get home from work I am going to take it for a test ride. Im pretty sure the problem came from where the wiring harness was spliced together on my bike. I will let you know how it goes. Quote Link to comment Share on other sites More sharing options...

AKheathen Posted October 29, 2008 Report Share Posted October 29, 2008 are your plugs wet, or do they look wet? sounds like glazing. i only experienced this prob once on my 583 rotax. i had just adjusted the timing plate fore higher rpm power aand took the air box off to let it breathe, then adjusted the carbs. ran great, and god awfull power(intake sounded sweet too) but i rode a little bit and then did a couple of hundred yard pulls (got up to 80, then stopped to turn around) then it bogged out and barely ran whn i took off. i was running br9 denso iridium plugs, and then went through my ngk spares. just kept torching them untill i went in and baught some br10 gold pilladium and never had a problem since. try wiping the plugs off with a dry q-tip and if they don't come dry, switch to a hotter plug. br8 ---> br9 ex.

Badapwned Posted October 29, 2008 Report Share Posted October 29, 2008 oh yah if your worried about your air screws, adj. the slide stop screws a little. Is this the same as the air screw or no? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted October 29, 2008 Report Share Posted October 29, 2008 oh yah if your worried about your air screws, adj. the slide stop screws a little. WHAT???? The slide stop screws adjust the idle speed and have nothing to do with the air/fuel mixture from the air screw...or did I read that wrong??

AKheathen Posted October 29, 2008 Report Share Posted October 29, 2008 WHAT????The slide stop screws adjust the idle speed and have nothing to do with the air/fuel mixture from the air screw...or did I read that wrong?? actually, they both do. the air screws adjust the mixture up to 1/8 throttle, thus controlling the idle speed too, but if it seems to run good in that range, i wouldn't worry about it. thats why i said IF your worried about it. half a turn out is a little rich Quote Link to comment Share on other sites More sharing options...

I agree it works until 1/8 throttle. But...once the mixture is correct, then you set the appropriate idle speed (1400 to 1800 RPM). When the mixture screw is set correctly, you will get your highest idle, but then you adjust the idle screw to the appropriate RPMs. From what you wrote (or how I read it) you're telling him to set the idle speed screw for the mixture....like I said, how I read it. That is incorrect...if that is what you're saying.... Sorry if I'm misquoting or misunderstanding what you're typing. Quote Link to comment Share on other sites More sharing options...
rtcc Posted October 29, 2008 Report Share Posted October 29, 2008 I have been having similar problems for awhile now. Only it would only break up in the low and mid throttle. I have finally narrowed everything down and it was just over heating. I was never spitting any fluid out of the overflow or anything. I changed over everything electrical and even poured water over the CDI and coil when it would act up and in never changed it. Finally just switched to engine ice and it has stopped except one time when it overflowed cause I was stuck in a deep hole in the dunes. So a bigger radiator is in my plans before next summer and it should take care of everything. Quote Link to comment Share on other sites More sharing options...
thepandaman987 Posted October 29, 2008 Report Share Posted October 29, 2008 i had this problem, the bike ran great for half hour, started bogging and eventually died for good. I had thought it was getting a weak spark so i put hotter plugs in but didnt help. Went through everything and found out the wires connecting to the key switch had come apart from bouncing around too much, hope i could help cause i know how much not being able to ride sucks Quote Link to comment Share on other sites More sharing options...

And...let me know when you're ready for that oversized radiator... Quote Link to comment Share on other sites More sharing options...
rtcc Posted October 29, 2008 Report Share Posted October 29, 2008 Two things...Are you sure the impeller is working? And...let me know when you're ready for that oversized radiator... Well I am in the middle or replacing my clutch right now and so I checked the impeller yesterday and all is good. Gears look good and impeller turns fine and everything. I can see the fluid moving in the radiator while it is running as well. I think my stock radiator might have too many rock chips. I have been through everything else, and it runs fine now with the engine ice. and yeah I will be getting ahold of you soon for that radiator.
