Thinking about these piston and rings for the rebuild. Anyone have any info on these! Thanks! http://cgi.ebay.com/ebaymotors/YAMAHA-YFZ-...sspagenameZWDVW

If I force the new seal in with some silicone, do you think it will hold? I am sure that someone has fixed this problem before.

I finally dragged the Shee out of hibernation and was trying to get her back to normal when I noticed I was leaking oil from the shifter seal. I buy a new seal, pull the old one, and try to install the new one when I see that the metal lip that the seal sets in is oblonged!! It looks like the chain must have been hitting on it over a long period and has cause the hole to warp! Is there any way to fix this. If I force the seal in it will tear it and will leave some gaps due to the out of round shape. Has this happened to anyone else??

If I can help keep mine and your families safe, I will go back for tour #3 if need be!! Scouts Out!!

Is he still around? What about IRideA250R? That was another reason that I shyed away from the HQ.

NYUK, It has been awhile! I just finished my 2nd tour in Iraq and that has hindered the Banshee riding or any riding at all. I will be home for a while and getting the Shee back up to par is one of my goals!

I am finally breaking the shee back out of her hibernation. Anyway, here is my crazy issue with here. I think I might have a coil problem, but wanted to check with you guys to see what you have to say before I buy a new coil. Bike starts and idles fine. It will take off good then sounds and feels like it falls off to 1 cylinder. I can pull the left cylinder plug wire off the spark plug and it dies. I replace that one and start back up and pull the right plug off and she runs but you can tell it is on 1 cylinder. ***Kicker*** I swap the plug wires and perform the same test and both cylinders die. Where as the other way the right cylinder would stay running. Should the engine die if one of the plugwires are pulled? I know this is crazy, but I am stumped!

12 Years now and I love it! If your scared say it!! 29N10, 35N20, 79T40, and 19D40 SCOUTS OUT, HOOOAH!! ^ ^ ^ Tell me what it is????

Dealer is full of shit. I know that they make a 22.5! I am not for sure if anything smaller. Mike

I have ran the Moto-fast 2 into 1 pipe for several years now and itis the best pipe for lowend XC/MX style riding you can get. Pipe with shaved head will give a lot of "pop" down low. Mike

I always wet my shee down, then soap down, then spray Fantastic on everything, let stand for 1-2 mins then take a scrub brush and use in circular motion. Cleans all the dirt out of the cracks and crevics. Then spary Tire Shine on the plastic and WD-40 on the motor.

Not trying to be a smartass, but dam it guys....LISTEN Right plug is """BONE DRY & WHITE"""" how in the hell can a bad coil or plug cap cause a fucking lean condition?????? I am not trying to start a pissing contest and I appreciate the help so far , but if you have no clue what in the hell your talking about then don't post shit in guessing what you have read before on another post and try to get your post count higher! rebelbanshee2, I have all the TORS disconnected. I can put either plug wire on the right cylinder and shee will idle fine and will run if the "LEFT" plug wire is pulled. It just goes lean under a load. My question now is has anyone ever had the crank center bearings/seal cause a problem like this. Thanks,Mike

Both side of the coil are firing. I asked the Yamaha shop and they said that 1 lead was the dominant ground source for the coil and thay is why it acted funny by switching the plug wires around. While there I also asked my buddy the service manager to explain where he is getting the center crank seal from. So he pulled a service manual and showed me that between the center journals where the center bearing is that it is sealed between the cranks. He said he that he couldn't remember if it was an actual "removable seal" or a machined seal. Then another mechanic chimed in and said that it was machined onto the crank between the center bearings and if it was bad it would cause a lean cylinder. SO they both agreed that while the right cylinder is pressurizing on combustion stroke and the left cylinder is vacuuming on the intake stroke, it is pulling the fuel charge from the right cylinder and burning it in the left cylinder I also removed the complete intake system. I replaced reed cage gaskets, triple checked carb & reed boots, borrowed some new take off carbs from a buddy and replaced my carbs. Removed the tank cleaned the petcock, pickup hoses that go in the tank, cleaned the tank with fresh fuel, and replaced all of the fuel lines. Still the bike idles fine and when I put it under load it drops off the right cylinder and the plug is completely white with no signs of fuel! So I guess I am off to tear her down and replace the crank. It is the original 99 crank. SO I guess it is due to be replaced. Where do you recommend getting a crank from? TIA MIKE

OK, Now it gets even better.!!! I can switch the plug wires and the right cylinder still runs lean!! Well, this morning I pulled the left plug cap off the shee while running and it kept running on the right cylinder. Then I replaced the left cap and pulled the right plug cap off while running and shee died!! So I switched the plug wires to the opposite cylinder and the reverse of the above happened!!! I know the wire is getting spark because it bit me real good. The plug wire that is closest to engine is the one that killls the engine. What in the @$$@# is causing this? I have never seen anything so f-ed up before! Thanks for helping guys!! BenBB, I have tried everything except the leak down test ( i am in the process of getting a tester together). I don't think that the carbs are the problem (never know for sure) because I have cleaned them very extensively and my shee idles fine and pulls out OK, just when it gets under a heavy load is when it drops the right cylinder. No popping or anything, just loss of power and the right plug always showing very lean. As far as head gasket I am running a cool head and I have checked the coolant and it is full. B370, No both cylinders are hitting, just the right one falls of under load. I have some used tops that I was given that i am going to try today. The bike never sets more than 2-3 weeks with out a least being started and rode around my yard for a few minutes TIA,Mike
