How far are you from zip code 44325? I ride trails if I can go fast and they are nice and groomed and not muddy, I hate to get my shit dirty. I would rather go back and forth on a clean field then get all muddy. I mainly ride on the street or on backroads, train tracks, and old strip mines.

Here is a post I copied from planetsand. It is a post where calvin pollet (maker of the cheetah) is answering a question about cheetah bores. In the middles of the post you can see where he mentions how long a nikasil plated bore will last. And remember, how many times have you had to have your cylinders re honed because they wore out and lost compression. copied directly from www.planetsand.com {"It also depends on which piston you are running. Is it a 10 mill or a 14mill, because they take a different piston series, with different cam grinds on the O.D. I am surprised that Millennium would have set them up that tight for you! "Back in the day", (as us old guys like to say it....lol), I ran some Dyno tests on a 70mm bore engine.....and the best hp results were from a clearence of .008, (that's right...8 thousandths of an inch!!!), we used a set of .010 over rings, (filed on the endgaps), to tighten the seal back up....and that was the best performance we got out of it. It was VERY noisey....and I am not recommending it as what to run on a set of cylinder bores. I am just saying with a nicosil bore, there is going to be no wear on the bore for possibly a few years, but if you set it up that tight it will require a MAJOR breakin time for the pistons to establish the clearence they need, EVERYTIME you put new pistons in it. I personally think piston clearence is kind-of like the oil ratio that a person runs......on the oil issue nearly everyone I have talked to that has run dyno and race testing runs rich ratios on the oil to get the best performance, as rich as they can stand it in some cases.........clearence is the same way in my book, you want it as "loose" as you can stand it, don't set it up already worn out.....but, (especially if you have a bore that doesn't wear), why not set it up to get the best performance you can and put a set of rings in it a little more often if it needs it."}

the email is talking bout the big cheetahs, but it doesnt matter, the only dif between them is reed cage size and powervalves. Powervalves have little to no influence on peak hp numbers, they just give more bottom end.

Below is an email from Dan at patriot racing. Maintenece free implies that no bore or honing work is needed when the pistons and rings wear out like regular cast iron cylinders. With stock cylinders you have to get them bored to the next level and get them honed. I never said you can melt down the engine and just put it back together. If you are not confident on jetting or on how to assemble a motor then it would not be wise to drop 2 grand on a cheetah. When properly jetted and assembled the cheetah is just as reliable if not more and makes gobs more power than the the stock cylinders. There are also two facts to consider on your journey as to how fast you want to go. 1. to go fast, it costs money 2. fast things break These laws apply to any motorsports, ie. cars, bikes, atv's. If you have not convinced yourself of this yet, then you will be upset when they happen. If anyone has a planetsand account you can visit planetsand and the person who designed the cheetah is a moderator over there and a regular on the forums. His name is Calvin Pollet. There are a lot of post on PS about the cheetah and Calvin can answer any questions. Here is calvin's website for cheetah: http://www.cpindinc.com/products/Yamaha/Ch...heetah_Cub.html "The 421 is a really great motor. Reliability is very good. Definately not a tweaky motor. With any performance motor- it is a good idea to upgrade the radiator. Even with a hot rod stock motor they can start to get hot in some occasions. A larger radiator eliminates this issue. This motor should easily get 150 gallons of fuel thru it before needing to take a look at replacing the pistons. With a Nikasil plated bore, theres no machine work involved- just drop in new pistons." 421 Cheetah Cylinder & Head Pistons Intake V-Force Gasket kit Porting- both cylinder and case/tunnel Cylinder plating 4mm Stroker crank We can set you up to run pump gas in this motor. -Dan "Quality thru Performance, Performance thru Quality" www.patriotracing.net Phn: 253.826.4881

The only chains that have snapped on me in the past have been aftermarket chains with a clip type master link. The place that broke was the master link, I guess it has to do with the clip thing. If you have a D.I.D chain look at the instructions, it says "D.I.D. strongly recommends you to use a rivet type master link even when the clip type is available." Rrivet type is the endless chain, like a stock chain.

I just bought this one and it fits 15 no prob and I shaved a little bit and it fits my 16 now too. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...sspagename=WDVW

yeah same here, I have seen in magazine where they can get a busa into the high nines, but all the stock ones in my area run tens also, in the 1/4

with proper torque they shouldn't come loose, but trinity sells this thing that goes on top of your plugs and prevents them from backing out.

there are drag banshees that do 5.3 in the 1/8 at 130 mph. All the stock busas that I have seen run the 1/8 have been in the mid 6's. http://www.wickedatv.com/DUportal30/home/default.asp go there to see the video

detonation, possibly

hmm, would you seperate any thing, if so how much for the crank and carbs

yeah something like that, a detroit diesel two stroke has 23:1 cr

I dont know yet, I am playing around with the division alg and number principle

yeah its a math course its called Real Analysis, its a real pain in the ass. putting the opposite of what I want to prove first is called proof by contrapositve ,and with this question since what I have to prove is compound, it makes it messy to do it that way.

that much compression takes away from peak horsepower because it takes so much energy just to compress the mixture, but torque goes up. my friends volkswagon has a diesel engine in it, it only makes 95 hp but has 170 ft lbs of torque, the compression is insane on it.

yeah they blow, way too much thinking involved, this is the only one I cant get on my take home test. I searched everywhere

its an analysis question let a,b,c be integers, prove that if a divides (bc) then a divides b or a divides c. i cant get past the first step

is brooke her hq name or is that her real name?

any body? I have a question

wow, 15 passes, so you get about 1 1/2 miniutes of balls out riding time, then change the rings. How much power does it make and why do the rings wear so quickly.

when you say unreliable, what do you mean? Does it break down alot? does it run on race gas or alky?

drag only motor....... Im listening, tell me more

what is the x-3 and is it a bolt on or do I have to send my cases for trenching and what not? does it run on alky?
