Re: Adding compression

I know I am putting a little life into a dead thread but I think I have just pissed myself with laughter

Anyone know if Kydan smashed valves, smashed into a tree or turn the 600 motor into a rocket ship and smash into the moon?

Re: Adding compression

Building a 600 = baaadd idea....you'll need boost, and that's not a fun road to go down, trust me. You really have no idea what you're headed for.(it starts with holed pistons, and ends with picking the rest out of your oil pan)

Then after all the money you dumped into it, you realized you could have just bought a FZ1 or whatever the fuck.

Just buy a second or third bike, like a sane person!

Im a machinist with access to any type of equipment I'd need, and if I wanted to I could bore the cylinders, deck the head for added compression etc. Im not wanting to go that far right now, but what I am interested in is porting the head(if that even needs to be done) and especially using a thinner gasket for higher compression. What I'd like to know is will using a thinner gasket cause interference between valves/piston/head and require further modification?

Will using a TRE with the added compression lead to detonation or will the ECU be able to retard the timing properly regardless of the compression?

If anyone has any suggestions as to other mods I should do while the engine is apart feel free to educate me, Im new here in the gixxer world.

Thanks!
Take it apart and measure the clearances. Don't waste your time asking on forums as people don't know the answers to these questions.

Porting - good luck. Very easy to loose power. I've tested loads of heads that were modified and made substantially worse than stock from both porting and/or valve job even from big name shops.

Don't chase compression, waste of time.

Detonation on a 600? Never seen it myself.

Fit adjustable cam sprockets and time it up, way way more power in that than compression. Stock timing figures are a bag of wank.

This is an old post, but I like reading what Tim Radley says. He does great portwork.... and has good advice

I will say though, that I'm american, and dont speak british, but I'm pretty sure that "bag of wank" = not good..... haha

Re: Adding compression

Ok, to answer OP's question (or 1 of them I think).
1.Get head off motor
2.Put Plastigauge or playdough or similar on piston
3.Replace head with gasket and tension.
4.turn motor over gently by hand
5.Remove head and measure thickness of afforementioned goo squished into valve pockets of piston.
That is your valve to head clearance.

Also a good idea which I've done with my 2 strokes is to use solder (like lead soldering solder for electical soldering solder) to measure squish clearance.
with head on:
1. remove spark plug
2. place solder in combustion chamber so it is hanging from plug hole and protruding into squish area of chamber (look up what squish area of chamber is, or ask that bloke above, his definitions are difinitively difinitive)
3. turn motor over gently by hand
4. remove solder and measure thinkness
that is your squish clearance.

On 2strokes this needs to be about 0.8mm or a wee smidge more for real high revving motors. Not sure what it should be on these motors.

If your expensive race-built motor has pistons kissing the head when assembled. Get another expensive race-built engine builder to expensively build your expensive race-built motor as it WILL explode in a spectacular and amusing fashion upon running.


just remembered i'm reading an old thread so talking to myself.

Re: Adding compression

There's no replacement for displacement. If you wanna really delve into something worthwhile and see huge power gains I would sell the 600 and buy a busa. I kinda skimmed through the posts but a single turbo is most effective within the 1500cc to 3000cc range. Depending on the size of the cylinders. On a 600cc (150cc per cylinder) the turbo lag would be a huge issue.

Not really... I have ridden turbo 600s, turbo 1000s, and turbo busas, and all spool very quickly and are fun as hell to ride. While the market isn't really there for a turbo 600, it can and has been done with good results. Turbo sizing is important to prevent massive lag, but I can tell you that the snail on @oldgixxer's turbo busa is the size of a small child, lol...
