Well the jetting seemed close when I got the shee, but now I have to bore it .080 over which is 66mm. Should I go up 1 jet size for every .020 over? Total setup is toomey t5's, ported cylinders, trinity 38mm airstriker 2 into 1 intake with no air box, bored .080 over, stock head milled down .030, +4 timing, and at sea level. Currently it has a 165 main jet and a 65 pilot, I just don't want to fire up a fresh rebuild and be lean. Also does anyone know of a thumb throttle set up that will connect with the 38mm airstriker, can't stand the twist throttle going threw bumpy trails.

I tried using the pinned jetting topic for some reference, but it doesn't tell anything about engine size, which kinda makes it useless. There are some guys that have engine info in there signature, but most do not. It is a great idea to have something like this pinned, but need more info for it to be usefull.

It sucks, the guy I got it from said he had to rebuild the motor and replace the right cylinder, I figured eveything would be fixed and good to go. Turns out the right rod bearing at the crank went, he must have just rebuilt the top end and didn't even consider to check the rods. So now I am rebuilding a motor that supposably has about 20 hours on it, at least this time I will no it is done right. The local guy that is going to be boring my cylinders confirmed that the reason for the engine damage was due to a rod bearing. He said that once the bearings got free they got sucked up and most of it got blown out the exhaust. He said I was lucky to be able to reuse my cylinders and casings. He said a .060 bore should be what I need, which takes it to .080 over now. Does anyone have a clue of about how much my jetting would go up by, by going .060 over?? Jetting was a 165 main jet with a 65 pilot jet, it never ran hot and plugs always looked good.

Well my right rod bearing at the crank went and now need to rebuild! Plan on getting new rods, bearings and seals. So my question is, can a home mechanic disassemble the stock crank and replace the parts?

I need to bore my cylinders and was just wondering what is the maximum safe size bore, they are currently .020 over? I have seen some pistons that are .100 over but seems there would not be much sleeve left.

Well checked the compression and the left jug was good but the right jug had no compression at all!

well I went for another ride today and shee kept stalling. I would pull the carb and remove the pilot just to find it clogged. After about the fourth time stalling due to clogged jets, a buddy of mine gave me a new inline fuel filter to use. Ran great for about 15 minutes and then stalled again, pulled the pilot jet and it was still clogged. While I was removing the carb I noticed that the new filter had already trapped a lot of stuff, could not believe all the trash in it, more then I would like to talk about. I finally got the POS out of the jet and I believe it was acting like a flap. fuel flow would push the debri over the jet hole and then I would blow in the other direction and it would appear to be clear but the fuel would just push it back and clog the jet again in just a few minutes. Unfortunetly I think it was too late, right jug was missing, sputtering, back firing, and sounded awful. I am going to check the compression later tonight with a friend. Will a filter mess up the fuel mix? If not I do believe the clogged jet caused the engine to run lean, on top of junk being thrown in the cylinders, leading to engine damage! Previous owner gave me a set of Vito's 65.92mm pistons and 1 set of rings, but I can't find another set of rings anywhere. I am just wanting to locate parts just in case. Thanks!!

That is the same carb I have on my intake and it runs great. Mine seems to load up on the lower rpm's and I have a couple smaller pilot jets on the way. What size pilot jet do you run with? I am sure there have been a lot of debates about the single carb versus the dual carbs, but for now shee runs great and will probably stay with the 2 into 1. If I would have gotten a shee with the stock dual carbs, I would have kept the duals. I have no plans for the shee, but I am not wanting a monster, I mainly trail ride. This isn't my first quad and I have found myself before chasing more power and still craving more power, it never ended. Only to reach a point and realize that it isn't a trail quad any more.

Thanks for the info, I am much relieved that it is not the motor. Although I have thought about just getting a gasket kit and taking off the top end just to see the condition of the pistons, rings, and cylinder walls.

turns out the nut for the stator has backed off and the key was at the bottom of the cover.

I fired up the shee and let it warm up, then putted around for about 10 minutes. started riding good for about 2 minutes and then It just died with a little back pressure sound, never did that before. Shee did not want to fire back up and I could tell that something was wrong by the way the kick starter felt, sometimes it would give a little kick back from the kick starter and sounded kinda like something was rubbing. I figured I blew a ring or something but, I recently got the shee and have not had any problems, last owner told me there was maybe 20 hours on the top end. I will probably start tearing the top end down tomorrow, just wondering if anybody has any input as to what might be wrong!

I took the carb off and measured it, it is a 38mm with a 165 main and a 65 pilot with an open air filter at sea level. Plugs look good but seems to bog down a little when pegging it at low speed, once the rpm's are up it rips. wondering if I should go with a bigger pilot needle. Any help on the jetting would be appreciated! I examined the carb boot good and does not leak, but that is first on my list.

Hello, just picked up an 06 banshee and had some questions. The seller told me it has been bored .20 over, ported cylinders, and a stage 4, 40mm 2 into 1 intake. I have looked and looked, but I have not found a 40mm 2 into 1 kit. I have noticed that the kits come with k&n filters and mine has a foam uni filter. I am just wanting to find out what size carb I have, because I need a new carb boot and would like to know what size carb is on there. Also is Trinity stuff garbage?? This kit is a little over 1 year old and the boot is dry rotted badly, but my buddies stock carb boots are about 10 years old and still look good. Found 1 boot on ebay but not for a 40mm and it was $75, I thought that price is outrageous for a boot that only lasted about 1 year. I am new to the banshee side and just wanted some advice on these parts, thanks!!
