JERKHEAD Posted March 1, 2004 Report Share Posted March 1, 2004 just installed a 28mm bored to 30mm - its already been pre jetted with a 155 main and the clip for the jet needle is on the 3rd slot ( i'm at sea level if it helps) and on top of the that i installed boyesen power reeds (which told me to go to the 4th slot to make it richer)... problems is - when i start the shee in full choke she she idles awsomely, but when i clsoe the chokes it dies... but it never dies when i give it a lil bit of throttle... what should i do? go richer on the needle one slot??? or.... thanks guys...

H300F Posted March 1, 2004 Report Share Posted March 1, 2004 i would check to see that your pilots arent to small. Quote Link to comment Share on other sites More sharing options...
Big Blue Posted March 1, 2004 Report Share Posted March 1, 2004 is your idle set? do you have your slides set right? Quote Link to comment Share on other sites More sharing options...
sredish Posted March 1, 2004 Report Share Posted March 1, 2004 i would check to see that your pilots arent to small. First, make sure your needle is 3rd clip from the top/blunt end. That'll help your idle a bunch. Then, get a pilot in there so shee'll idle and then get your main set. Once your main is set, then concentrate on dialing in the pilot. Don't worry about getting the pilot perfect yet, you just want it to run so you do a main jet check. Quote Link to comment Share on other sites More sharing options...
JERKHEAD Posted March 1, 2004 Author Report Share Posted March 1, 2004 it idles fine when the choke is full but stahls when i close the choke... yes both carbs are sync perfectly... im gonna go a slot richer on the needle , to see if that wrks today...

If it doesn't idle well, your pilot is probably too lean. go up on the pilot till it will idle, then finish the main and then get back to the pilot. What floats, I've heard that the float bowls in the wrong carb can have idle problems as well. Good luck and let us know. Scott Quote Link to comment Share on other sites More sharing options...
williebiv Posted March 1, 2004 Report Share Posted March 1, 2004 Your bike setup sounds alot like mine. My carbs 28's tapered to 30's went on last year. I ended up going up one size on the pilots and richened up the needles one clip. The mains have ended up at 175 may be alittle rich for you but close. If you just put them on you will have to dial up the idle screws until you get a good idle. Quote Link to comment Share on other sites More sharing options...
JERKHEAD Posted March 2, 2004 Author Report Share Posted March 2, 2004 alright guys... took the shee out for a run today and got her to idle - thanks to you guys... boy does shee pull hard and strong - what a freqin difference!!! new problem... when im on full throttle on sixth gear it pulls then tends to slow down then pick up again (like it hit its peak or something)... is this also a part of my jetting??? thanks guys for the help again...

If so, how were they colored, if pretty dark thats alright, unless you have some bogging at full throttle, then your machine may be telling you its a tad too much fuel. Check the plug and if its pretty dark, back the mains off on more size and the bog should disappear. After you got the main fixed up did you have to play with the pilot? What main and pilot size did you end up at? Quote Link to comment Share on other sites More sharing options...
