.....a waste. that's all been done before but with a 340 kit and even with porting which you don't mention, the bike didn't make over 26 horsepower.
if you do a search, the whole writeup is posted here somewhere. anytime the KLX is mentioned with the adjective "beast", it's pretty funny. now a KLX450, that's a beast. but 26 horse? come on......

with the extra dough you've invested in all your parts, you could've bought a Husqvarna TE250 which would kill your little project- stock.

 

What I choose to do to my bike is not a "waste" if I am happy with it, and what I choose to call it is too. All the extra horsepower with no added weight, in my book, is worth it, so I will continue on with my "waste" of time and effort.

 

can you plate a TE husqvarna?

 

I wear pink knickers IG. wanna f wid me sounds like you couldn't tune a corn hole to a good Obama Debate.

 

Yes you can plate a husky te. I wish I boughyt that instead of the bmw I need the 6th gear, that's why I'm selling it.

 

Don't waste bandwidth trying to reply to mister 'gotta have the last word no matter how I sound.'

If he would have done the search he recommended to you, the ported 331 (not 340) made just over 27hp, not the less than 26hp that IG claims. The man's not even good at reading posts much less modding bikes.

I'd say your setup is good for about 28hp if jetted properly. You'd probably have to go to bigger valves, do some port work and reshape he chamber to get it into the 30's though. Definitely share the results once you get the dyno run.

In stock form, the KLX's air induction is optimized for about 315cc. In fact, one of my buds recently got just shy of 31hp with the Yosh cams, 315cc kit and CVK carb jetted with a 132 main. When you get beyond 315cc without doing valve, head and port work, you start having to deal with changes in the swirl and tumble of the A/F mixture, so the bike becomes less efficient at higher RPM. Your 350cc torque curve will be stronger, start earlier and be more flat than the 315 though.

 

Opps by the way I don't think I'd ever use the term monster and klx 250 together. Now cr 500 or kx 500 those are monsters. Lol

 

No agument there!

 

Yes, that's exactly what we are seeing so far. I love the way the engine hits early with the torque, and pretty much holds strong from there, and signs off early. As I mentioned, it fits the bill perfectly for my uses. Revving the thing to 9 or 10K rpm doesn't fit into my riding. I love a good tractor engine, and an early shifting technique. YMMV.

Bill and I will always strive to only present the facts.

A debate on "maximum performance" just isn't part of my thread. There's dozens of threads that discussion fits into much better. Why these threads always seem to take that turn is baffling. I suppose some are just tuned to that song, I don't know.
Real world results will be forthcoming soon. I plan to ride the dickens out of it this weekend in the Hills.

 

Hee, Hee. A trials bike with Gonads, Well done gentlemen four stroke machines baffle the average gentry. We are in a weird time Trials ? dont even think about it Kinda like yoga with heavier wieght and smooth cream being forced down yer throught.
