This may be the wrong way to word it but.....

I want to make my '03 YZ450F have a more CRF450R like powerband. I rode a fellow TT'ers '03 CRF450R this past saturday and I really liked the powerband on it. My bike will happily break the rear tire loose at 1/4 throttle and his bike will just grip and pull. He said that my bike would act the same if I just got a flywheel weight. So, I want to know how much I should add. All your help is appreciated!

A flywheel weight is key for every 03 was under weighted from yami period....

You will get all kinds of answers to which weight....

Fox MX only 4-8oz ..... DRD, GYTR, Stealthy, ZipTY all of them sell them

I settled for a 5oz GYTR - works great. :excuseme: ain't no CRF.....the power is more linear on the CRF and harder hitting on the YZF

Goto to the Yamaha site to GYTR section, they got flywheels for $100, and you can put the stock one back on when you need less weight

Two things:

The 8oz Dr. D flywheel (you can exchange it anytime for a lighter one, but trust me on this. it won't be a bit slower on the straights)

A Power Bomb header.

Then run your buddy's CRF out of a loose corner and see what happens.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I could use some feedback, My son is getting into off road riding so I have starting getting back into it as well.  We mostly do trail riding but did some MX track riding last year and he loved it andso did I.  I have a 2003 TTR 225, it's nice that it has an electric start but the suspension is too soft and it doesn't have enough power for my liking.  When I was riding the MX track I was having issues bottoming out on the larger jumps.  I want to change to a more off-road capable bike.   I won't ride it much and don't want to spend a lot of money, I think I prefer a 2 stroke, when I was younger, in 1990, I raced an 89 RM250 and loved it.  I am looking at a 96 RMX 250  and a 98 YZ400F, both bikes look to be in good condition and around a thousand dollars.  I like the RMX because I think kicking a 2 stroke 250 should be easier than a 4 stroke 400 and the simplicity of the 2 stroke engine.  The 400 sounds good because of the low end torque I assume it has but the cost of rebuilding the 4 stroke if needed worries me and I have heard they are hard to start. Should the RMX be decent for an occasional trip to an MX park?  Any thoughts on these two bikes?

      Brand new, still in the packaging Lexx end cap fits the stock muffler of 2006 & 2007 YZ450f and 06-13 YZ250f. Comes with a forest service approved spark arrestor and two different size tips. Don't spend hundreds of dollars on a slip on, this tip can be quiet and forest legal or loud and make power! Also a note for WR450 guys: get this tip and find a used 06/07 YZ muffler, fits directly on 09-15 WR450. $80 shipped free to the lower 48. PM, call or text 406-223-8789

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator work? Anything else I should know? Any help would be appreciated. Thank you.
