If I were going 4T, it would have been the Beta.

I tried to kindle an affection for the 4-stroke but I couldn?t muster it.

I?ll look do to a video report in a couple of weeks.

No ride video yet. Head is at RK-Tek getting squished.

Rosin core measured at ~1.8mm.

As I was applying my race graphics I remembered I hadn?t checked the piston height in the barrel.

At BDC, the piston is flush with the exhaust port, while being a goodly bit above the intake port. Maybe a couple mm.

I'm going to squish my 250.. Maybe tuesday!

Are you keeping the port timing the same? Can you see how many gaskets they've stacked in under the jug?

I have no rationnale to alter the port timing.

The gasket appears to be a single, black (0.5mm) unit. No green showing.

Exhaust is perfect. What happens if I add thicker base gaskets to all of that?

You'd move the power curve up further.. and have an even bigger squish clearance.

I was just curious. TBH I haven't even really had a look over my new bike yet.

More top end, less bottom. You will be increasing the squish clearance on your new rk head as well.
