blaster2006 Posted February 7, 2009 Report Posted February 7, 2009 (edited) Just recently installed my mods, (K&N filter, pipes, 280 mains, and turned air screw 1 turn out). it ran fine etc, plugs SEEM fine, if im off jetting im sure its just by a VERY little bit, and if something im guessing im abit rich. but anyway, bike runs fine etc, but today, i raced another banshee for fun, and this is what happened. i launched from 2nd gear (i had a perfect launch), accelerated fast enough to go into 3rd (like i always do, always shift at the same time etc), but this time with my mods, when i hit 3rd, and pushed the throttle to full immediately ( like i do when racing ofc), for 1.00 sec exactly, the bike would NOT pull... loose power completely then after 1 sec it pulls again and shifts through the rest of the gears fine... i dont think its from lean jetting, but what i could say is my reeds are bad, and the petals have never been changed since the previous owner i bought it from had it, its a 06 banshee with stock reed cage and petals. and when i tore my shee apart when installing mods, my mechanic wanted to check the reeds, before he pulled them out, he did "his test" to see if the reeds are good. we took the carb off the intake, and then he put his hand over the intake and blocked it completely, he then gave it a few kicks, and then he said he could feel air blowing against his hand which meant i had bad reads (i noticed before he kicked it that he put the key switch on "on") and he said that since he felt air push against his hands from the intake boot, when he kicked it, that it means ive got bad reeds. so could this problem be from bad reeds, the not so quick response or pull. whatever it is. note: this did not happen when my bike was stock, also this does not happen if i cruise... it only happens when i race ( and i think it only happens on a slippery road with some sand and rocks (rocky sand), im pretty sure on road if i race launch from 2nd and shift to third it pulls instantly... i will check again on that tommorow Edited February 7, 2009 by blaster2006 Quote
VWMIKE Posted February 7, 2009 Report Posted February 7, 2009 Bigger main jets! I know you think your rich enough, probably are down low, but bet your lean up top! Quote
blaster2006 Posted February 7, 2009 Author Report Posted February 7, 2009 Bigger main jets! I know you think your rich enough, probably are down low, but bet your lean up top! yeah, but i dont think it would make the problem how i listed... Quote
sleeper06 Posted February 7, 2009 Report Posted February 7, 2009 (edited) What position is your needle in,sounds to me like thats your issue,if its pulling good up top yuor main jet is fine,I would try richening your needle a liitle bit at a time,if it gets worse go the other way,are u running stock pilot jets,if so i would jump up 27.5 pilots and give it a try. A good set of reeds make a world of diffrence on a basically stock bike Just saw your running pods,might need to go up to a 290 or 300 main, your temp will make dif to rite now its 20 deg by me i would go with the 300 cold wheather still sounds like main is close try needles Edited February 7, 2009 by sleeper06 Quote
mazuullaa Posted February 7, 2009 Report Posted February 7, 2009 I would try a larger main jet first alot of people with your mods are in the 310-330 range. It is easy think you have the right jets but you should do a plug chop that is a good way to know. Quote
Rodneya Posted February 7, 2009 Report Posted February 7, 2009 You are running lean. Reeds will always have some blow-by, that is why there is a crossover tube. Why do you waste money on a mechanic if you are asking for advice here. HQ members give advice for owners who want to do their repairs and mods themselves. If you are using a mechanic you should trust him and if you cant, get rid of him. Quote
harbinger of death Posted February 7, 2009 Report Posted February 7, 2009 did it do that just the one time? or is it every time? seems to me that if it was not jetted right it would be in all top gears. I see by your picture you still have the stock carb tops, is the tors still hooked up? did it seem like it lost spark for 1 second and then refired? and either stop paying your mechanic or stop asking questions on here every damn day.

I saw your other post about the coolant overflow, what your mechanic don't know about that, or what's wrong with your bike now? I say your just wasting your money with him, I just got my shee like 3 months ago and did not know anything about them and I have learned alot about the bike thanks to the guys here cause there's alot of guys here that know what they're doing and don't mind to give you advice and try to help you out.

RollinRhino Posted February 7, 2009 Report Posted February 7, 2009 (edited) Someone offered me good money for my 28s so I let it go. (I hope he doesn't renig because I went through the trouble of putting my 26s back on) Anyway......You shouldn't be running stock reeds on larger pipes. You really need to allow as much flow in to get the most from the exhaust. Get some pro reeds and keep the stock blocks for starters. You'll feel that thing wake up. I am running 280s on mine and its almost right. The needles are too rich though so I have to fool around with that part. The point is that it is useless to fool with it letting the stock reed setup choke that motor. Edited February 7, 2009 by RollinRhino Quote
blaster2006 Posted February 8, 2009 Author Report Posted February 8, 2009 look, i dont pay my mechanic, he helps me for free as a good friend, i just tipped him once for the job where he cleaned my carbs and put my pipes/ filters on, thats it. i gave him $20 for that, other than that for the little things etc he does for me, i dont pay him, so why not have him help me. i agree with that i have to move the needle up 1 notch ( lower the clip notch 1 time, so pointy part moves up abit). its just the bad response i got atm which is annoying.. got delays alot.. noticing it more and more i drive it.. it pulls when i gas it top after some time but it pulls way harder when i actually wait for it to respond from the massive delay, when it was stock it had better response.. but not as much power as it has now when i actually give it time to respond Quote
dave5.0 Posted February 8, 2009 Report Posted February 8, 2009 I ran stock type reeds in a few bikes and never had any problem with them. Is it crazy hot where you live? When my bike was stock and it was hot 90+ with 80% hum I remember running like a 320-330 main. I think I ran some needles that came from Vito's so god only knows what they were. Have you ever jetted your bike all the way through? Sounds like you ride pretty much like the rest of us. Alot of playing and play racing. You would probalby be happy with the max power at the safest jetting possible so you don't have to worry about burning it down when you hold it wide open. I've been told by a few builders the best way to do that is start at the bottom and work your way up. If you know all this already I won't bore you with it. If not let me know and I'll continue.

duner Posted February 9, 2009 Report Posted February 9, 2009 Your guys test was spot on. The reeds should not let air blow back into the carbs. I think you are correct for letting him help. Quote

I think you are correct for letting him help. great that i know this, i knew hes an OKAY mechanic . like i said my problem is RESPONSE.. but once it has time to respond its powerful. in my opinion, im thinking ill need to richen the needle and move it up ( move the clip down 1 notch), and the V-force reeds to top it off, will make my response MUCH better hopefully?

quikshee Posted February 11, 2009 Report Posted February 11, 2009 To me it sounds like your mains are a bit to small. 1/4 to 3/4 throttle is controlled by the needle, WOT is controlled by the main jets. I'm running pods,pipes,ported stock cages w/boyesen reeds and i'm running 320 mains 3rd clip 27.5 pilots and a tad lean on top because of the temps here, but I havent had a chance to get her out this winter. Aftermarket reeds will make a big difference on your throttle response for sure, my ported stockers made a noticable difference. VF3's I would imagine are better ten fold. Quote

VF3's I would imagine are better ten fold. funny, just installed V-force 3 reeds, the power gain was MUCH less than i expected. something very hard to notice. i could not notice any power gains in any area thats weird. maybe the fact that i bought a used set, but the reed petals looked mint on the mand they had low hours Quote
