yeah i know i wish i had a choice, but it was either buy 290 jets for $13 plus 310s for $13 or the Jet kit for $30 which includes what sizes i listed i got. 280 -300 - 320 one of those three will be far better than what im running 270s. im guessing 300 will be my sweet spot. but i did read going from a very low humidity to a high humidity will yield 0-2 smaller mains. going from a desert to a humid wisconsin. im assuming ill have to compensate for that. i will find out once im able to run them and chop the plugs.

just to be clear he was jetted for 3300-3500ASL 
i will be jetting for 900-1200ASL
also,, id bet he threw smaller jetting on to compensate for the heat too, it gets well above 90F in the desert. we barely ever hit 90F in our summers. So ill have to adjust for that too.

well guys i got my kit and filter in the mail today. and installed them within 30 minutes after my shift. took a few kick to get the fuel pumping in the system, bottom line, i had no idea how strong these things idle, i cannot wait to feel it on the move...one thing i noticed, i defintately had the slides put in backwards, interestingly i put them back just as i disasembled them? they were backwards from day 1 i got it... i swapped springs from the carbs to see the slides drop CUT OUT facing me/ air filters...only way theyd go. so happy to accomplish this simple and stupid task. put 27.5 jets and 300 mains in. possibly a little rich but alot better than 25 and 270...and wrong facing slides... still waiting on the new petcock and clymers manual, you guys made it possible to do the jetting without the manual, which my impulse thanks you for (,sheester_98 especially.) this weekend i plan to clean and oil my pod filters, reinstall a new petcock, and with any luck find a tail light bulb/ or assembly in town. i also measured my carb to reed port. im not sure how to measure it, but i took inside, outside, and mid diameters. inside: 1 1/18th" outside 1 1/2" mid 1 1/4". the circumference of the port on the carb is 4 1/2".
any help on the carb measurements would be gratefully accepeted. i know to convert to MM, after i get the answer how to measure carbs ill be in business. thanks all.

ok after a google search with banshee HQ i see to measure the inside diameter, or AIR flow. which im at 1 /18" or 28.575MM. i measured with a tailors tape measure, not calipers, im asumming im running 28mm mikuni in that case being not as persise as ideal.

for sure i plan on bring it out to my rentts house in the country asap, once off work. im tellin you man, it is smackin on idle.the confidence that comes with a smooth reliable idle is insanley better than running off tune. like said, 300 might be ric, but already with the set up i put up seems stupidly stronger than before. we will see

Could be some 28mm carbs but i know stock is 26mm and they coukd have had the stockers shaved to a 28mm but not sure. But hopefully you can get out and ride that hog soon

just fyi, the carbs look unmachined, measured both without any sign of machining. hell, that could be the point of shaving carbs, alas im asumming they are factory 28mm at this point, i did not mis-measure.

Well if you know know then id go with it lol but did the shee idle nicely for you

yeah man haha it felt good knowing its right where it needs to be, carb slides were backwards since day one some how. probably explains why i couldnt kick it over without throttle before haha

but ahh hey guys my petcock came today, my manual did not. point being, i need some knowledge. limitied smoke comes out on idle, yet starts and idles great. i can confirm that there is NO gasket between the bowl and the housing in the carbs. why is there no gasket when i read that there should be...the imprints of an older carb even show that a gasket used to be there...should i get some gaskets in there if i suspect an air leak?

ok i got my cylmer manual, replaced tail light bulb, cleaned and recharged my pod filters, stopped the fuel petcock dripping leak. just cleaned it, now i have an extra petcock laying around. still need to plug chop but i know im not lean anymore.

 

i bought an actron compression tester, i tried reading up about my silly quesiton im about to ask, dont blast me, but im having trouble simply screwing the extended 14mm tube into the clyinder. just dont see how anyone has enough room to spin the thick rubber tube 20 times inbetween the chassis and head?

Take your tank off lol

haha fair enough. pretty funny i just had the tank drained today, i didnt think to drain it before cleaning the petcock, turns out that was a terrible idea.
