Go with the Yamaha. It will be much more reliable than the Polaris  

question? How hard is it to jet a yfz450? Also any comments on the jet kit? Another thing what about an exhaust which is the most recommended?  

personally i prefer Toomey exhaust, they send the jet kit needed along with detailed instructions on how to re-jet and re-tune the carb.

without this it can be a bear to re-jet if you haven't jetted a carb before.  

Thanks I was confused on that. Ive heard people tell me that yosh makes a great pipe and muffler. Just wanted to hear from an outside person. Question to the people I'm getting the yfz450, Now a friend of mine told me that his ltz400 (stock) can beat it. Is this true? Want everyones imput if possible.    

oh geeze, tell the guy that he is dreaming!!

my yamaha blaster 200cc outruns my friends ltz400.

no the yfz450 will make the ltz400 look like a pedal car.  

That is awesome cause this guy annoys me. He talks alot of crap. Can't wait to show him up!! Thanks I just can't believe he said that wow amazing how he believes that.  

shoot me a private message and i'll see what i can to help you tune that yamaha to peak factory performance.  

I actually wont have it til the end of this month. I had to lay away the remainder due to the fact I'm getting married in 2 weeks. So all my money went there. But after that I should have it in 2 1/2 weeks. The only downfall with me racing that guy is I have like 60 pounds on the guy. But if I tweak it a touch, pipe, jetting, better tires. That may make up the difference. Like I said the outlaw beat him at first. But in the top end he past me.  

he must have a 440 big bore kti in that thing.  the ltz400 is fairly strong, but even my yamaha blaster smoked his ltz400.  

Picked up my yfz450 3 days ago wow what power im really happy with the purchase. I have a quick question for the yamaha fans. I want to get my wife riding with me. But I was wondering the raptor 250 or 350. She has no idea how to use a clutch. She may not even like it. Is the 250 a big difference to the 350. I mean she will never ride fast so am i just better off with the 250? Also I hate that damn break in period i really want to open my new yfz450 up and it really wants to be! I just hate that break in period!!!  

I have a 2000 yamaha kodiak 400 automatic >it was running fine ,always cranks on first try.I cut it off the motor seemed to want to run on ,like dieseling . When I tried to crank it back it hit but want catch up . It is getting gas and seams to be firing .I don't know if it is firing constant .It will hit as long as starter button is pushed . Where do I start ?  

To wolf, I have a quick question about my 2008 yfz450. I was riding around and well i didn't notice it at first but the stock pipe was red hot. It was a night ride and it was red hot. Now I talked to the dealer I purchased it from and they told me that was normal being that its a high performance motor and all that compression coming out of the exhaust, causes it to burn up. Now that was the first time I ever noticed that. Just wanted to make sure that was normal. Is this true. I know that I have asked this next question but what is a good quiet exhaust to buy. Im not into loud because of the trails I'm on wont allow that. just want a performance pipe that isn't louder than the stock but adds to the performance of the quad. Please help for I'm an idiot when it comes to this stuff!
