Not too sure about the OS engine, Nova engine is something like 4.29mm I think. If the crankpin is worn, your engine may keep eating plugs, like what I had recently. Try turning the flywheel and check the freeplay to TDC. What I normally do is apply some oil on the gap (where the conrod meets the crankpin and see "how much" bubble it creates.

-- so "how much" bubble is considered ok?

Yea I may have to check that. I got it past that 75% throttle thing. So by checking the bearings im mostly checking for play right.

Just in case you guys in Europe and the UK are wondering. The OS MAX .12 TZ(P) 3 port Part no 11373 is 100% BRCA and EFRA legal. 7.0mm crank bore with an unbroken crank exit

OS only make one version so no matter where you buy it in the world it will be OK. I just got one and its pretty fast. More power than the Mega i would say

For $185.00 its a real bargain!!

Cheers

Default FS: OS TR R Spec with spare threaded shaft

hey guys
im selling an os tr r spec 3 port turbo
has had about 2 gallons of fuel in awesome condition and compresson on this engine is so tight, never pinched or squeezed liner.

however one slight problem, one of the heat sink bolts into the crankcase is threaded i have replaced the 3 other screws with bigger screws for added durability.

engine has the orignal sg shaft for use with on road cars and also a threaded shaft so you can use this on trucks.

i am selling this for $100us

pics available please email at [email protected]

Thankyou
