i havent seen the 540 kit i thought they made 88mm bore piston kit and its a 523 cc

LA sleeve has a kit that goes to 89mm, which should give you a 535. You will have to have a cast iron sleeve installed, they run OK, not as well as some other setups, but good.

have bore replated not sleeved

there is a company has custom wiesco piston for the 540 kit.

this is the website I was looking at. has anyone tried them

Bigger is not always better. Having a well tuned 500cc KX will outrun a measily 540cc anyday. I've seen it a billion time.

thats right

 Put the monster on VP. Ask Hill Climb 147. He loves the stuff. It is great for race bikes, and requires very little set-up. Jetting is the change. There are a bunch of upgrades to make you scream.
 Are you talking about a dirt hillclimb or the road race? NAHA just raced here, in Indiana, and they had a 0-540 class. It was mostly 450's, and had a qualifier round. Only top ten went on to race.
 Either way, jetting, gearing, and tires are where its at. A kx 500 can be the fastest bike over most other cc's because of power to weight ratios and of course brutal kx power. The trick is getting the set-up correct.
 I thought the 540 kit was a stroker kit for the Cr 500. It has a short stroke so, I think, they put a kx crank(longer stroke) in it with plenty of mods to make it happen. I first heard about the 540 kit on here. It requires that you lose the powervalve. If you do that you might as well get a CR.

Forget that flywheel weight. That is to tame the power. So is the reed spacer. It helps control power to the back wheel. The weight can smooth out vibrations, but still slows it down, in my opinion of course.
 Wow, road race? maybe over sized rotors are something you might need. The k5 goes straight really well, but I think lacks in brakes and turning technology. Thats the benefit of the k5 on to 250 or 450 chasis mods. There are guys running the beast on the roads. See what Doordie or Stewart recommends.
 When you want some hill climb on dirt tips look me up or Hillclimb 147 is better yet. Plenty of go fast help on here, I'd only be worried about slowing down and turning especially 156 times.

You can do a 540 or for that matter a 560 without losing the powervalve, the 87-88 cylinder works well using a honda rod and piston and a cylinder spacer. motor builds loads of torque but doesn't rev as quick. You can do a 535 with out changing the Rod using a LA sleeve piston (89mm).

I agree with both Gowen and Stewart, a well tuned k5 with a few aftermarket parts can be a rocket. I have both a 535 and a 560, and frankly my stock bored 500 is easier to ride, the 535 is on nitrous so it has a cast iron sleeve (plated cylinder will not hold up to NOS), I use the 560 as a spare motor because the stock bored setup works really well.

For my .02 I would get my stock bored motor working well, such as a lectron, v force, PC exhaust, head and cylinder mods and maybe a crank balance.

  two stroke thoery says that the moter does best at 1.0 stroke to bore size i would work on known  power incress at 86 by 86 till iwas happy i had gotten all i could  before opening a can of worms  like the things that you would effect from stoke or bore incress

That's why I want to do a 88x88 mm engine. I think that's a great Idea but there are some thing that need to be addressed. Lots of welding needs to be done to make it dependable.
