bansheerilla Posted October 9, 2009 Report Share Posted October 9, 2009 just rebuild the motor got some port work done and hard to start the bike have to kick it for like 20min and it will start if i put starter fluid to the carbs it starts right up though. Also when i ride it when i hit the throttle all the way to take off it sputters alot and i hold it for a while while it sputters all of a sudden it just takes off and its all good from there go through the gears fine but when i come to the stop and try it again it does the same thing whats the problem im running 330 mains and 30 pilot and stock needles on the middle slot. NEEED HELLLLP. Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted October 10, 2009 Report Share Posted October 10, 2009 We need more info, such as mods, elevation, and temperature. It's lean, and that's why it's hard to start. How many turns open are the air mixture screws? Quote Link to comment Share on other sites More sharing options...
pr0blumz Posted October 10, 2009 Report Share Posted October 10, 2009 Did you connect the choketube between the two carbs? Quote Link to comment Share on other sites More sharing options...

RippinShee Posted October 13, 2009 Report Share Posted October 13, 2009 Sounds like youre pretty rich man. Do some playing around. 27.5 Pilots should be all you need period there. Try dropping the main one size, and leaning the needle clip on position also. Quote Link to comment Share on other sites More sharing options...
potpye Posted October 13, 2009 Report Share Posted October 13, 2009 I would clean the carbs with Break Cleaner and then blow out every whole and opening with air. Do the float bowls have fuel in them? It sounds like you are not getting fuel. I would run the following: 300 Mains 27.5 Pilot 2 Turns on the Air screws Set the needles to the middle position to start with. You definitely want to make sure the carbs are in sync.

Ive tried pretty much everything ive cleaned it all out took all parts aparrt and cleaned them out i have 320 mains after trying a couple others thats not the problem i think its the pilot jets need to be bigger im waiting on some bigger ones in the mail right now. imn going to try that and get back ill let every one know if thats the problem in case someonme else has this problem.

dajogejr Posted October 15, 2009 Report Share Posted October 15, 2009 If you just put it back together, do a compression test AND a leak down test. All the jetting and electrical advice in the world means nothing until both of these are done. Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted October 19, 2009 Report Share Posted October 19, 2009 Also make sure the bowls didnt get switched from side to side as they ARE different. The one with the lil bb at the bottom goes on the choke knob side! Quote Link to comment Share on other sites More sharing options...
donkeypuncher Posted October 19, 2009 Report Share Posted October 19, 2009 i have 30 pilots and 320mains and i tried the screws turn half one one in a half two and two in a half and still the same im 42ft above sea level and the temp is about 70 degrees still need to know what your mods are?(pipes, filter(s), reeds, timing, cool/milled head...etc..) as potpye said, make sure your carbs are synced. the problem you are having sounds similar to that of others that just had theyre cylinders ported and it turned out to be carbs that werent 100% synced.
