Anyone own a Yamaha Four Stroke?

[Gobes32]

Thanks guys. I was really worried about the valve aspect. The reason i am buying a 426 is due to the fact they represent good value and i really want a four stroke. I am riding track only because my brother is 13 and just received a KX 85. So until he is older and licensed then we are stuck to the motocross tracks. When i do buy the bike i am going to be very vigilant on the maintenance and it won't be revved very hard while i own it. :

Mate dont be worried about valve aspects at all chances are if you get a good cond bike you wont have to worry. Just maintain the basic oil and filters n blah blah and you will be sweet! I met a guy that has an 03 YZ426 the idiot hasnt changed the oil in 2 years and its still going fine. Just blows a tad of smoke. What a nob though. But shows how good they are.

KTM are as reliable as a lawn mower thats been throwen off a cliff. Wouldnt touch Suzuki or Kawasakis 4stroke stuff as they havnt long been into it. Where Yamaha and Honda know what they are doing.

Just remember you dont have to get a 426. a YZF-CRF-250F has more HP than my old XR400R.

Ride in the dirt befor you make up your mind. Because if you buy something thats to fast for you. Trees hurt. And they hurt alot. TRUST ME ive broken many bones on trees by riding bikes to powerful for me when i was younger.

Hope this helps.

Lol, a 426 has 2hp less than a 450, I wouldn't consider that a big differnce.

And as for crf is you're talking about the CRf-r you gotta be off your dial to touch one of those if you're not racing.

It's more about the delivery than the outright power that makes the 450 so much better. It's alot easier to rider a 450 quicker for longer than the 426.

426 to 450 is a big difference not only engine but all different seat/tank/plastics/suspension.
just try to get the newest bike you can or one thats done bugger all work.

My mate has one. Scares the living krap out of me everytime i ride it. Cruzin in top gear which is 5th and mid revs and open it up and the damn thing does wheelies on me

WR450's have the best spread of power if you are comparing it with the 426.

I have ridden WR400's, 426's and 450's and i can say that the 450 feels like a 4 stroke, unlike the snappy delivery of the 400 and 426.

I would LOVE a WR 450 but for the time being ( and budget ) I am sticking with a 2002 YZ 426. When me brother is older and able to get his licence we will do a bit of riding with the Otway Trail Riders Club. Can't wait. :

Does anyone know what a top end rebuild is worth? Just for interest sake?

[Gobes32]

Hey guys, I bought a bike today on ebay. Item no. 220085528562. Appreciate all the advice from you guys especially Thor who took the time to pm me, thanks heaps.

looks good from the pics mate.
top end rebuilds can vary in price its like how longs a peice of string...
valves are about $110 each x5, piston kit around 250$, cam chain $80(put one in as its most likely stuffed by now!) and then it depends what the cylinder is like cause they are plated and can't be honed (very much), cylinder is about $500
thats just a rough idea plus u have to get someone to do the work..
