dieselhead Posted January 23, 2011 Report Share Posted January 23, 2011 just did a topend on the wifes bike , having trouble with it starting when its cold had this problem before the build i have to kick the shit out of it and it will start then die then git it started again and its a struggle to keep running . I have not done anything to engine asfare as mods that would affect jetting ,bore is stock with stock head only mod is timming plate slides are timed , pilot is stock main is 300 and needles clips are one down from center also has t5s p,s once the thing is warm its fine Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted January 23, 2011 Report Share Posted January 23, 2011 First off, I would clean the carbs. Second, you need 27.5 pilots in there with aftermarket pipes. Chances are it's not getting nearly enough fuel upon startup. Do that stuff first and then report back. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted January 23, 2011 Report Share Posted January 23, 2011 No two motors are the same. It's obviously a fuel delivery problem. The pilot is too small. Quote Link to comment Share on other sites More sharing options...
06specialedition Posted January 23, 2011 Report Share Posted January 23, 2011 Is the choke tube in between the carbs? That gets people alot....and half the time your bike will barley run or not even start. Quote Link to comment Share on other sites More sharing options...
bonerific250 Posted January 23, 2011 Report Share Posted January 23, 2011 another common problem is the float bowls being switched to a different carb, make sure the bowl with the brass ball on the front is on the left carb. i've had this problem it was a bitch to start and to keep it running.

sleeper06 Posted January 24, 2011 Report Share Posted January 24, 2011 Whats your compression,if its stock bore did you hone before you put new pistons in,If so whats the piston to cylinder clearance,wisecos run .003,stock pistons run much looser,you might have a clearance issue Quote Link to comment Share on other sites More sharing options...

bonerific250 Posted January 25, 2011 Report Share Posted January 25, 2011 (edited) The bowl with the brass ball in it is the choke jet. when you pull out on the choke plunger it crates vaccum and pulls gas up and threw carbs by-passing the pilot and main jets. the ball for me anyway, is just a quicker reference to what bowl went where.if you take the bowls back off and look inside both you will see a small jet. who wants to strain their eyes. Glad I could help. Edited January 25, 2011 by bonerific250 Quote Link to comment Share on other sites More sharing options...

01blackshee Posted January 26, 2011 Report Share Posted January 26, 2011 thanks, she is booonerific. Toomey reccommends for the needles to be on the 4th setting.. and to use STOCK 25 pilots.. and depending on ur elevation on the main jet. they reccommend a 280 main from sea level up to 2500ft higher elevation they reccommend bigger jets.. I installed 27.5s and it ran like shit.... as locogoat stated above. every bike is different..!! Jus need to figure out what works best with your bike.. http://www.toomey.com/html/t5-inst.htm.... check this page out.. i did what they said and it runs like a champ now!!
