How well do the stock carbs feed all that additional space? Do the YZF450 front shocks bolt onto stock A-arms or do you have to buy aftermarket?

PM sent, do you have a phone # I can contact you at?

Just wanted a second opinion from you guys before I take the bike in. I took the carbs off twice and cleaned them, replaced all jets (stock sizes), cleaned the whole fuel system out, replaced with 93 octane & Klotz. The thing will fire up with starting fluid, and will run if you keep giving it gas. It will die on idle. I tried all adjustments on the carbs and I cannot get the thing to idle. Also, if you give it alot of throttle it will hesitate and then rev to the moon. I wanted to refreshen it anyways and figured I'd take it to someone who knew what they were doing, as I have limited experience with twin cylinder two strokes. I will try the skull suggestion, sounds pretty sweet...

Sounds like a great starting point, Thanks for the advise. Like I said, I don;t need a full out race machine but I gotta be able to keep up with the new 4 strokers. I'm at about 600' elevation.

Good feedback, thanks. I guess $1500 would be a budget to stick to (engine only). If I spend more than that, I might as well just sell this thing and buy a newer 450R.....

What brand components? What size cylinder? What size / brand cyl head? Any other small cheap mods that work well together as a package? I have already upgraded the rear tires to Knarly's with a wider stance in the rear. I am most concerned with letting this guy build up the motor and drivetrain right now. Something like A-arms and shocks I can do myself. I just want an expert to be building up the engine because he knows all the tricks, what runs good, what combos to use, and hopefully it doesn't grenade the first time out. I am willing to spend some cash on this, however, ideally I would throw $1000 at this right off the bat. If it takes more, I'm willing to spend. I cannot justinfy pissing money away just to freshen this thing up. Now, if it takes money to go scary fast, that's another story, one that I'm willing to spend so more coin on. I forgot to mention, I am intrigued by big displacement Banshees. What is the ideal cc to go big that still retains some manners? I am more interested in total "power under the curve" vs. top end output (Top end HP #s are only good for bragging rights if you ask me).

Pic from a few years ago when the TRX was stock. We were pretty even drag racing, depending on who hooked up first:

Here's the lowdown: I'm taking my bike to have it rebuilt / modded. It is a low hour '97 Banshee that I let sit for two years (I've owned it since 2006). I went through the bike and cannot get the thing to run. A combination of frustration and wanting to have it done the right way, I'm taking it to someone who has built quite a few of these things. I have to try to keep up with a friend who's on a TRX450R modded that he races. So, I'm going to modify the piss out of this thing. What are some good options to make this thing a beast all around? I will be trail riding at Wayne National Forest in OH or Hatfield McCoy in WV. I'm not going to race this thing but I want it to be fast and reliable. I want to be able to jump on the thing and go without having to wrench on it every other weekend. It needs to be pretty bulletproof. I would rather sacrifice HP for longetivity. This bike is 100% stock. I plan to spend most of the money on the engine and full exhaust. What is a realistic budget to add some serious HP with a full engine rebuild? What size motor would you suggest? What are some things to avoid? Thanks for all feedback.

Thanks guys, I appreciate the help, BTW, is it possible to pull the shift rod out of the case while the trans is still assembled?

The shifter seal is leaking bad on the 'shee. The previous owner said he punctured the seal and dug it out, then pushed the new one into place. Is this possible? Is it necessary to remove the tranny, crack the case, and remove the shifter shaft to replace the seal?

Yeah, both cylinders work fine. It sounds healthy, and fires up just fine. The bike only has about 150 hours on it.

Ever since I got the bike I have to wind the piss out of the motor to go anywhere. I cannot let the clutch out at low revs because it will fall on its face. If you do get the bike to move from a stand still in 1st gear, it won't go anywhere until it hits the powerband/or is almost to the top of the rev limit (I have the throttle buried the whole time). To go anywhere, you have to rev the pee out of it and pretty much dump the clutch and take off, but you quickly run out of revs and have to shift. I know this is a two stroke with a pretty mean powerband but this doesn't seem normal. Can this be a Reed Valve issue? Is this common to anyone else? The bike is a '99 Banshee stock. Brand new clutch, jet needle clip set to 3 (factory setting), stock jets, stock spark plugs. Thanks.
