Bri894 Posted December 28, 2009 Report Posted December 28, 2009 Can any of you guys help me. I bought a 99 Banshee in May (stock except for Toomey T-6 with jet kit). It's been running strong up until a few weeks ago. I put new plugs in it already. I run 93 octane gas w/maxima K-2 oil mix. It use to start on 2 to 3 kicks. It now takes about 6 to 10 kicks to start and it runs rough and stalls out when I put it into gear. I have to really lay on the throttle to keep it running. Any help? I don't really have anywhere to take it except the stealership which I don't want to do. Quote

GNR101 Posted December 28, 2009 Report Posted December 28, 2009 the tube between the carbs is inplace? check your compression and your sure the carb jets and veins are clean.. not just look it Quote
ELKARACING_SHEE Posted December 29, 2009 Report Posted December 29, 2009 well what i can tell you is that, if it starts in 6 to 10 kicks, you must have an air leak, you said that it ran strong, so there could not be any bad adjustments from the carbs. it would be better to check the compression, because the compression tells you where to start. If you have good compression then its an air leak somewhere, if you have bad compression then its time for a new top end Quote

If you have good compression then its an air leak somewhere, if you have bad compression then its time for a new top end Sorry it took me a couple of days. I had to borrow a compression gauge. I got 90 pounds from both cylinders. I also threw in 2 new plugs (NGK) and drained the tank and made 2 new gallons of 93 octane gas/oil mix. It's still doing the same thing. Quote

I did take me 6 or 7 kicks to start it. It is 35 deg where I live but I keep my bike in the garage . Quote
2/2 many banshees Posted January 1, 2010 Report Posted January 1, 2010 (edited) Sounds like a jetting thing. Where do you live and where did you get the bike from? What do you have in it for jets? What kind of intake set up? What does it have for carbs. Edited January 1, 2010 by 2/2 many banshees Quote
98_shee Posted January 1, 2010 Report Posted January 1, 2010 hmm looks like you got plenty of compression, i mean your only 5 psi off of a brand new top end, it must be an air leak, does it still start hard? Compression on a stock bike should be around 120, not 95. I did take me 6 or 7 kicks to start it. It is 35 deg where I live but I keep my bike in the garage . Did you do the compression test on a warm motor, with the carbs wide open and kick it till the needle stoped moving (normally 10-15 kicks)? Has the temp droped since the last time you rode it? You may be lean on the pilot trying going up a size on it and see if it helps. What is your current jetting, elevation, temp? Is there any other mods beside's pipes, stock filter? Quote

I did warm the motor up before I tested it and put a little pre mix in the plug hole before it kicked it. I kicked it about 1o times. The last time I rode it was in West Va, it was about 50 deg. It started running rough the next time it rode it, it was about 35 deg in NJ. It has Toomey T-6 pipes with the jet kit, uni filter and a boost bottle. That's the way I bought it. Quote
98_shee Posted January 1, 2010 Report Posted January 1, 2010 What kind of comp tester did you use, what size jets are in it now, whats your elevation? You may just be lean on the pilot. Quote
Bri894 Posted January 1, 2010 Author Report Posted January 1, 2010 What kind of comp tester did you use, what size jets are in it now, whats your elevation? You may just be lean on the pilot. I used a MAC tester ( I borrowed it from my boy who works for a Ford dealership). I don't know the jet size. I think it came with the exaust. The guy I bought it from had the bike for 5 years and he bought it from the original owner. The Toomey pipe was on it when I got it. My elevation is probably sea level. Quote
