Stinger Posted August 8, 2005 Report Share Posted August 8, 2005 My Shee was running great for a few months and then it slowly developed a small sputter/bog if I'm just cruising along at a low RPM and pin it (or give it any sudden throttle). It's not a bad bog, it's just enough to create a small hesitation before the tires start spinning. I wasn't worried about it until I got into a few situations where I needed power "right now" and got it a half a second too late because of the hesitation... My theory is that the warmer weather lately has caused it to run a bit rich and I need to take a bit of fuel out of that area of the carb. Problem is, I don't know if I need to mess with the needle, idle circuit, or what. I know it's not a main jet problem. I'm running the stock carbs, mods in sig... Any ideas?

reded Posted August 8, 2005 Report Share Posted August 8, 2005 Lean up your needle by moving the clip up one position. Also drain your float bowls, maybe theres a small bit of water in them due to condensation. Quote Link to comment Share on other sites More sharing options...
Yaxy Posted August 8, 2005 Report Share Posted August 8, 2005 When you say a sputter/bog what do you actually mean? I like to think of a sputter as a rich condition. A bog is more of a lean mixture problem. If a sputter I would say riase your needle one position. If a bog I would say turn in air screws all the way. If better you may have a dirty pilot jet.

Chris 402293[/snapback] I suppose a hesitation is the best description of it, basically it does "nothing" for a split second, then goes crazy as it should.

dajogejr Posted August 8, 2005 Report Share Posted August 8, 2005 Before I changed clip position, air screw or pilot...I'd take both carbs completely apart, clean the bejezus out of 'em...then freshly sync 'em back up. Might be a good time to make sure there is no gunk in the bottom of your tank, too. If it still hesitates...then...I'd start with the needle....it really depends on where the bog is...on the lower end of RPMs...probably just turn the air screw out 1/2 turn or so. (Less than 4K RPM) If more in the mid...4K to say about 6K or so....then, Needle clip. Good luck! Quote Link to comment Share on other sites More sharing options...
Yaxy Posted August 8, 2005 Report Share Posted August 8, 2005 If you have not cleaned your carb in a while, I would start there since the problem does not seem to be a recurring issue. Make sure all jets are removed and cleaned preferrably with an air compressor. Install, Sync carb cables and then your idle and see what happens. If still prominent then drop your needle one position. Chris Quote Link to comment Share on other sites More sharing options...
dajogejr Posted August 8, 2005 Report Share Posted August 8, 2005 I'd even go as far as stripping some thicker speaker wire, taking a strand and gently running it through the smaller holes in the carb and smaller jets..... Hell...if you're gonna do it...do it right!! Quote Link to comment Share on other sites More sharing options...
