knight_ripper Posted July 13, 2007 Report Share Posted July 13, 2007 some history. Bike ran killer, for the past 3 yrs. Last race I blew out two reeds on the V-Force 2 system. On right side carb. Wouldnt run....took me out of the race. In same race my frame broke in two places after the IMS oversized tank mounts busted on one side. I said fuk it and kept going....thats when one side of the steering frame broke...then on last lap other side broke. then the reeds went. I had slowed considerably after the frame broke...I thought I was having an overheating problem...but turned out to be the reeds. It was in the 100's out in the desert that day...I was on mile 90-105 when shee broke. only 30 miles to go. SUX. got home, took off air filter, only 1 reed found (dont know what happened to the other one). Found 1 reed in my carb completely verticle holding up the slide (open). Replaced with V-Force 3's. 5 months and a new 06 Honda/ALBA built 450r later (racing only) . Now the shee is trail/dune only. I finally got around to messing with it the other day. first thing I emptied out the gas. Filled with good stuff. Changed spark plugs. Changed fuel filter. Put on the new reeds. took her for a spin. Shee ran for about 15 minutes real stong. i liked the new sound from the V-3's. then bam....I was downshifting ... turning a corner. when I came out I gassed it and she started sputtering, backfiring, and wanting to cut out (but not dying). took it back....cleaned out both carbs. started her up....shee idles....shee runs thru all gears 0-1/4 throttle. but the second you gas it....sputter sputter pop pop. If you massage the throttle.....wam shee takes off almost throwing me off the back. and sputters almost instantly. then gas it agian....seems like it has some throttle in there ... but not enough to get her going. did compression test.....120 PSI per cylindar. any ideas? Im thinking needle jet. I called v-force....they said the same thing. but they also said that the system shouldnt require any jetting. specially going from 2's to 3's. HEEELLLLPPPP.

knight_ripper Posted July 13, 2007 Author Report Share Posted July 13, 2007 I have advanced my RS stator to +4. I wonder if changing the timing will affect the sputtering and backfiring. hmmmm. Quote Link to comment Share on other sites More sharing options...
RIPRuck Posted July 13, 2007 Report Share Posted July 13, 2007 Bring the timing back to where it was at and see how it runs.. What oil ratio are you running? Dont know why advancing your timing would make it run like that as myself and others are running @ +4 also. Sounds like its starving for fuel! Good luck... BTW.. Nice banshee!! How did it do against all the other quads (4 strokes) in your races, are you running a stock stroke and are the cylinders ported? I love hearing about banshees still racing at the tracks! Good luck with the new one. Quote Link to comment Share on other sites More sharing options...
knight_ripper Posted July 13, 2007 Author Report Share Posted July 13, 2007 In the desert shee is the fastest around. I would pass 4 strokes in 6th gear on straightaways....but they would always catch up in the rocky sections and turns. same with MX. kicks ass when your on the throttle. nothing can touch it. but once you get into tight turns the 4 pokes would pass me by. I have never taken worse than a 3rd place finish. been racing 5 years. Also with the 5.6 gallon tank I would pass peps in their pits. I loved the distance that tank can take me. over 100 miles.....Id always fill up round the 90 mile markers. Also....i stoped racing her cuz its just too tiring compared to the 450r. the banshee is a rocket. constant pull on my arms and body would tire me out. specially on the track. cuz it has such thrust. now on my 4 poke I can race all day. well almost...hehe. but really, the power ban is spread over the whole gear versus....wham power....like the banshee.. Also...the turning. with newer bikes your looking at todays geometry. versus a banshee's ... which is what? 1986 geometry. so with the new 4 poke I can ride longer, with less body fatigue, and with this thing built by ALBA and Honda....it keeps up if not passes every quad out there. no porting or polishing on either vehicle. the 450r was Wayne Matlock's '06 vegas to reno bike. He is honda's pro rider. It was built by honda's guys and pimped out by ALBA. wayne and a guy from honda dialed in the suspension and I have to say its the most plush ive ever riden. NO BODY ROLL. It was put in ALBA's showroom right after he took 1st place in that race. just waiting for meh. lol I picked it up with all the trimmings at a great deal. its a smokin ride. after riding my shee for so long... I couldnt go to a stock bike. the 4 stroke I got had to be off the charts...and this bad boy is just that. ive had 2 races on her so far....I took 2nd in my first race and 1st in my second race. vegas to reno is in a month and were entering it. fingers crossed for another first place finish.

wesw Posted July 14, 2007 Report Share Posted July 14, 2007 are the slides in correctly the cut towards teh filters, also you might swap out that rs stator with a known one many are having problems with them. Quote Link to comment Share on other sites More sharing options...
knight_ripper Posted July 14, 2007 Author Report Share Posted July 14, 2007 three part question. any chance carb's outta sync would cause this reaction? I know my right one is just a pubic hair before the left. You can see the white in the one window and not the other...a little more throttle and the line is at the top of the right carb window and the left is at the bottom of the window. is that accurate enough...or should I sync them. second question....how do I raise and lower the slides to sync them? no tors...just caps on top carbs. third question...if my needle is the problem....which way do I move the needle to lean her out. reading all the threads on here...Im thinking Im too rich. which is causing the bogging, sputtering, and backfiring. move them up or down? im thinking moving them up will richen the carb mixture...and moving it down will lean the mixture.

knight_ripper Posted July 14, 2007 Author Report Share Posted July 14, 2007 i read about that slide issue. I will check them tonight when I get home, to verify that they arent backwards.. they should be right. I always take them off one at a time to keep them straight...but ya never know. also....rs stator....ricky stator stator. well known stator. i brought up the +4 advance, cuz I read where some people advanced it too much and got backfiring and so forth.

wesw Posted July 14, 2007 Report Share Posted July 14, 2007 usually backfire is a sign of lean. what do your plugs look like black or white?? i was suggesting you just swap out a stator to see if yours is working correctly, also your wood riff key is on teh crank and fly wheel.

knight_ripper Posted July 14, 2007 Author Report Share Posted July 14, 2007 oh great now im really confused. lol. on the backfiring thing. Is there a difference between a backfire and a poping. I want to record my quad running and get it on here for the pro's to listen to. carb's never have been my strong suit. i was noticing yesterday .. .that my left plug is half black and half milky...and the right plug is black as black gets. thats why I was lookin at the carb sync. I guess I could have an air leak too. weird that sitting for a few months would do this. I thought it was the V-force 3's. but im starting to doubt that. I still have my stock stator. changing it out wont be an issue. jsut have to take her apart again. thanks for the help bro. Quote Link to comment Share on other sites More sharing options...
