Dinner Posted September 8, 2006 Report Share Posted September 8, 2006 I would say you are lean if the choke has no effect pulled out. What do your plugs look like, and does it get easy? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 8, 2006 Report Share Posted September 8, 2006 How about a compression test. Lower compression will make it hard to start cold...but it could still run good once warmed up... You should never need the choke to start it once it's warmed up... Your jettin sounds about right on the main, and stock needle clip (middle on stock needles) and stock pilots (25s) should be fine as well... Also...fresh gas? Fresh plugs? Clean air filter? Cleaned out carbs?.... Just a few things to think about.... Quote Link to comment Share on other sites More sharing options...

nicktoney Posted September 9, 2006 Author Report Share Posted September 9, 2006 well the bike starts no problem when its hot, just a BITCH when cold... carbs are new and just cleaned... ill check the plugs and such later on tonight though... ahhh gas is fresh too.. it really screams when its hot though... but i thought that if you could ride it hot and put the choke on, and it didnt bog or spit, that your jetting was off? mine screams like normal no matter what the choke position once its hot... hmmm Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 10, 2006 Report Share Posted September 10, 2006 How about a compression test. Lower compression will make it hard to start cold...but it could still run good once warmed up... That's great....I understand the carbs are cleaned, fresh gas, etc. How about that compression check???? You'd be wise to do that now...rather than later. If it's low, you can probably just put a fresh top end on and be done with it. Wait for it to blow up from being worn out...it's a whole new checkbook... I'd bet it's low compression...period.

nicktoney Posted September 11, 2006 Author Report Share Posted September 11, 2006 well, see the thing is, i dont personally own a compression tester, and my buddy is bringing me his at the end of the week.. i actually think its carb related becuase here is what ive done since its been running like this. i got a tors eliminator... ordered everything from the same local guy. gave him my carbs to tap and thread. in the process, my carb cap threads were smashed when i got them returned so the new caps didnt thread on. i ordered some used, yet in great shape stock carbs from a member on here, and when igot them i cleaned them, hooked the new cable up, synced the carbs and replaced the jets with what was running perfect before.... then when i went to kick it over, it was sitting in the garage all night in the cold... got to about 50ish... still cold, the next morning, didnt want to kick over, not matter how far out the choke was... finally after a shit ton of kicking, it fired up.... ran great.... now, after ive ran it, and its even remotely still warm (not hot) its one kick and it starts... only COLD starts and its shit. and when im WOT with choke "on" i get no spit or sputter. which leads me to believe my top end is fine... i will however check my compression as soon as i get the tester... if my idle screws that are drilled into these "used" carbs arent setup very well, will it not start when its cold? could my slides be set down in too far according to the cable?

dajogejr Posted September 11, 2006 Report Share Posted September 11, 2006 That can easily be checked by holding the throttle open a little...just to idle it. The jetting can't be that far off it if starts and runs GREAT once it is warmed up. If your friend shows up with a cheapy type compression tester, you need to either buy a good one, or take it to a dealer and let them test it.... Wait....you have the choke on in WOT??? Cold or warm? And it runs fine? Stop riding the bike....and check compression as soon as you can. You should also check while you're waiting the pickup gap on the flywheel....just for giggles. You've already ruled out fresh gas and plugs... Your jetting is fine...or good enough for it to run AND start cold.... Quote Link to comment Share on other sites More sharing options...
ohiobanshee Posted September 11, 2006 Report Share Posted September 11, 2006 Going up to a 27.5 pilot would probibly help cold starts. Quote Link to comment Share on other sites More sharing options...
nicktoney Posted September 11, 2006 Author Report Share Posted September 11, 2006 yeh, see thats what made me wonder? all this started happening after i swapped carbs and took the tors off.. the first time after i did it all it was hard to start cold.. my buddy has a snapon tester... annnnnnd yeh, i did that choke test... i was told if you pulled the choke out after it was hot and it ran fine, jetting was too lean... and if it spit it wasnt lean... i havent been riding it, so thats not an issue... yes ill compression test, but im confused because it all happened immediately after tors removal and different carbs. coincodence? maybe?

jlsparky7 Posted September 12, 2006 Report Share Posted September 12, 2006 Try turning your air screw in a turn or 2 Quote Link to comment Share on other sites More sharing options...
ALTVATER Posted September 12, 2006 Report Share Posted September 12, 2006 i need help figuring out what size jets i should have in my bike. i have a 99 banshee with a top end, pulling i think 349cc or 350cc. i have a cool head with 21 domes and boost bootle. also K&N with v-force 3s and toomey 6's. i just got it and it had 230s, i was wondering if 320s r too big for my motor or if someone had a similar set up what they ran in theirs???

dajogejr Posted September 12, 2006 Report Share Posted September 12, 2006 Welcome to HQ... Do you have a K&N in the air box, with lid, without lid, pods???? They make the difference.... Quote Link to comment Share on other sites More sharing options...
ALTVATER Posted September 12, 2006 Report Share Posted September 12, 2006 I have my K&N in my air box but i run no lid. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 12, 2006 Report Share Posted September 12, 2006 Alt... If you at or near sea level, and run in the 65 to 90 degree temps, throw a 280 main in there... 230 is too lean with T6 pipes and no air lid.... Quote Link to comment Share on other sites More sharing options...
