kwakman:
im not particularly up on suspension stuff but remember if you have a lengthened swinger,it acts as a longer lever so shock spring imo would need beefing up a bit.

You can put 4.25x18 sun rim on a K5 with no mods at all just shorter spokes , you can run the 5x18 excel on the K5 with an extended swingarm with a few mods, its what I run on the drag K5. You need to cut off an old spocket to use as a spacer to bring your spocket out for clearance from the side of the tire this will require yamaha sprocket bolts. then you need to mod the wheel spacers to move the rim to offset the rim to the brake side a quarter of an inch. the 5 inch rims put a whole lot of tire on the ground. the terra-flex is a little heavier tire if your interested in trying one I have 2 that are like new , they didn't work for drag racing my brother found out .CBX

Also remember swingarm arm angle will affect the torque the motor has on tire. Just think about the angle you have going up the hill on the swingarm.

Yeah, maybe if your swing arm is wider than stock, All my swing arms are the same width as the stock swingarm, meaning there is no way you could add a sprocket width and clear, but I will keep that in mind if I ever want to go with a wider wheel. I use 530 chain on my bigger bikes, those that would use the widest wheel.

There is a balance between the traction and length, you can go more aggressive on the tire, and will have to go longer to keep a balance on the front end, shorter and a less aggressive tire will accomplish the same thing as a aggressive tire and length, the key is to know where that balance is. it does change from hill to hill and from morning to afternoon, you just gotta keep up with the hill.

Kaw Rider, thinking about the angle of my swingarm to the ground? You think its better to be parralel to the ground or to always stay above parralel. I would think swingarm getting flat would take away from force applied to the ground, but think the sag settings set all of that up. Am I missing something there?
  I saw plenty of Terra flex tires on Hillclimbers. They are usually on big bikes. I don't think they work as well on 500's as a typical nobb. Its a very aggressive tread pattern and very heavy. It was too much traction for my buddies 750 triple, so I definately don't need that on my 500. Thanks for the offer, Cbx.
  I found out that the longest I can be, Don. The axle has to be inside of the tip of rear fender. I'm able to get out even with the rear '93 Fender mod with this new set-up for the 600cc Class. Looks like I'll be racin the fastest guys and the conditions of the hill. With Stewart Power and the new Stretchers getting set-up, I am graduating to the Insane Racing. Most Fast Times of the Day come from the 600cc Class. Alot of guys thought I was nuts Hillclimbing a stock length 500, wait till they see me on this Green Rocket.

If you noticed my brake line stretched out, I am going to get a green Brake line and install the chain today. I hope that the racing season goes as smooth as the build went for this bike. No stressin' when you do your homework. Thanks for all of the help guys, direct and indirect advice as well.
