I have heard of sheeve upgrades and upgraded CDI boxes, these are both supposed to be fairly simple.

The CDI box is simply plug and go, the sheeve involves an install.

Well on my 450 this is what I have done to it.
1. cdi
2. jet kit
3. utv crap sheave
4. fmf exhaust

But if you are look for 50 mph speeds out of the 450 forget it. It will not go that fast. My right now will do about 43 mph. But I still need get the carb tuned better and my it will go a little faster. The only thing is do expect to 660 or 700 speed out of the 450 because it won't happen.

Here a link to a thread that I have listed all my mods in.

Hope this helps you.

I have a 450 too. I had the Yamaha dealer put in a different ignition modual (chip), that made a pretty good improvement.

Almost all stock bikes, quads, and Rhinos need to be pretty choked up to pass EPA standards. To get the full potential, you need to let more air in, more air out and then ballance the gas to suit.

Be careful with aftermarket exhausts. You may end up with lots of added noise and not so much added power.

I would stick to the simple things and get some modest increases. If you have lots of money and need a big gain, then trade it in on something with a bigger motor.

Like the old hotrodders say, there is no substitute for cubic inches.

From what I understand, it will take a cam and piston to make a SIGNIFICANT difference. Improvements with a sheave and CDI are minor simply because the 450 doesn't have the power to hit the current rev limit hard -- so moving it up, or allowing the belt to ride higher on a machined sheave won't do a whole lot.

But, add a piston and cam and you'll see a noticeable difference, and those will allow the increased rev limit of a CDI to work for you, while pushing the belt up that sheave. Note, though, that you'll have to run premium gas if you go with a higher compression piston...

Bottom line is that it's going to cost you some $$...

Were all just stating the fact that it is impossible for a little baby 450 to hit 72 "MPH" with nothing other then a few lil bolt ons..... .. feel free to email me your video of you doing 72mph and I will gladly admit being wrong. But until then if you wanna hang with the big dogs. You have to quit pissing with the puppies :) my email.. [email protected]
