I found CL3B an amazing engine in buggy but for truggy use its gets too hot as its right on the premium of its power.
Its very odd as it seems slow but its not its just the way it delivers the power
Anyone who has one running hot especially on 30% please check amount of head shims should be 0.8mm one of mine didnt have enough and whilst the motor is new an extra 0.1mm does no harm.
Another mod being done here is to fit a CL7B crankshaft to give more bottom end but with price of parts you might as well buy the 7B to start with.
The pipe supplied sounds great and mine run best on NR C6G plugs.

How many shims does it come with to get you to 0.8mm.
I've noticed a lot of variations in the amount of shims Sirio uses on their engines as well.
