Compare the engine specs, the yfz is a much more aggressive build than the raptor. Much higher compression, mean cam timings, and a dohc setup just to list a few. The raptor is and always has been a cruiser/trail machine and not so much a racer. The raptor is held back a lot more than the yfz.

No, there are no battery issues with the yamaha raptor. There have been some one-way problems but it seems to be a hit and miss thing, also the 04 model supposedly had some changes to it.

if you ask the people that have problems is because they probably only turn on their quad every year for thanksgiving. but you can use a batery tender that keeps your batery alive, its around 30 bucks on ebay.

Battery Tenders are about 15 bucks at WALMART[img]i/expressions/face-icon-small-wink.gif[/img] Everybody should own one!! they work.


Maddogg is right, The 450 is sold in a much higher state of tune, then the Rappy. The potential for the rappy is WAY HIGH. But if you want a good quad that has all the motor work done for you, then the 450 is better deal. IMO.






Bigger.

uh, all 660 raptors come with the SAME exhaust/intake setup. [img]i/expressions/face-icon-small-confused.gif[/img]
Uh no....They might look the same on the outside but its fact that there is indeed a california model, Yamaha had to make the california model even more corked to abide by california's strict pollution laws for the green sticker. The california model makes anywhere from 2-4 less horsepower than the raptors sold in other states.

The model #'s are as follows:

5LP1-All models except California
5LP3- California only

the cali models are more "choked" via a more restrictive exhaust, to keep polution down.

Yes its true some local dynos are showing 45-50 horsepower on california raptors with full airbox pro flow/noss machine/ or sixt sixt adapter airfilters and full exhaust systems. Dynos from trinity racing and power pros to be exact

I also see you didnt even try to reply with a comeback to the california raptor subject. It has been nice owning you

Wow, you must be Einstien. No CA models? Hmmm, then why does Alan Knowles from CT state that their test quad that only made 36 hp stock was a CA model and then after their pipe/filter/jet mods, it makes almost 50 hp? Go to their website and look at the Raptor section - you'll find it at ctracing.com.

If you are going to make some sort of statement dissing another person on this board, or come back with some remark about their age, then please back it up with some verifiable data. Just stating that there is or isn't something, or other simple opinion won't cut it.

Otherwise, it appears that you may be the one that really doesn't know what you're talking about or that you are not as experienced or as old as you pretend to be...

So who do you own??? Yeah, that's what I thought...
