98_sheester Posted May 3, 2015 Report Share Posted May 3, 2015 Yes you should have got 290s and 310s but the higher you go up if its about 1700-2000ft you need to drop a main and if you go down it should be a size bigger Quote Link to comment Share on other sites More sharing options...
yzf2yfz Posted May 3, 2015 Author Report Share Posted May 3, 2015 (edited) 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 900-1200ASLalso,, 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. Edited May 3, 2015 by yzf2yfz Quote Link to comment Share on other sites More sharing options...
yzf2yfz Posted May 5, 2015 Author Report Share Posted May 5, 2015 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.

yzf2yfz Posted May 6, 2015 Author Report Share Posted May 6, 2015 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.

98_sheester Posted May 6, 2015 Report Share Posted May 6, 2015 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 Quote Link to comment Share on other sites More sharing options...
yzf2yfz Posted May 6, 2015 Author Report Share Posted May 6, 2015 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 Quote Link to comment Share on other sites More sharing options...

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.

yzf2yfz Posted May 6, 2015 Author Report Share Posted May 6, 2015 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 Quote Link to comment Share on other sites More sharing options...
yzf2yfz Posted May 6, 2015 Author Report Share Posted May 6, 2015 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?

bendog Posted May 7, 2015 Report Share Posted May 7, 2015 Get gaskets! Wont leak air into there. Likely will leak fuel out of there though. Quote Link to comment Share on other sites More sharing options...
yzf2yfz Posted May 10, 2015 Author Report Share Posted May 10, 2015 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?
