Having the squish tight will help reduce detonation through better cooling of the piston crown. But you have to reduce the compression down to sensible levels. That will naturally cut into the squish area a bit and bring msv about right.

Clearly the piston crown should be parallel to the head. Wedged shape is not a tool required with a reasonable engine on OK fuel. And never a wedge closing in to the center.

and comparing fuels between straya and usa you have to remember we use RON as our standards and they use MON.

So, Rick?s 91MON is roughly equivalent to our 95RON, correct?

Something like that..

95RON is closer to 85–86MON... which is about 91 PON (Pump Octane Number)

Rick D - Dave at Two Stroke Performance has said with appropriate jetting, there?s no reason why my bike won?t run well on 91 octane fuel. I am lucky enough to have good 98 around the corner from my house, though..
Mine is an EC mate, i would like a GP but the deal i got on the EC was too good to pass up.

We also have the billet head available now for the 2018 and newer 250 and 300..

We completely re-configure the chamber.. We have done ALOT of testing with the Gas Gas and have got a chamber design that is woring very well. Compression ratios vary with elevation and octane.. We do NOT just have 1 chamber for everybody.. not the way we roll.. everyone is custom tailored for the application


Cost to rechamber i $150

Billet head is $325 and we only have a few in stock.

My bike is now fixed. I had the head cut by TSP (Australia) to lower squish to 1.35mm. I also had a closed-throttle lean condition caused by the slide being too high. This was throwing up red herrings regarding jetting & compression.

Running perfect.
