Thats interesting.. my XL3 and XXL3's came with 0.3mm head shim. XL3 is rad, but I have high hopes for the XXL3. Larger crank bore than the XL3, maybe after Nigel breaks in my XXL3 while I am in colorado for some "personal" business we can do some side by side testing of the XL3 vs XXL3. Two NT1's and Two maxs lol.. good times

also the XL3 and XXL3 come shimmed for up to 25% nitro. 30% add a 0.1mm shim etc. Or you can do the old offroad trick, add 0.2-0.3mm of shim to take the power down a bit and add more when it starts getting soft. obviously tune and plug will be different.

Cheers,

Patrick

anyone have any advice if the head clearance is safe with the XXL3? a .1 shim as standard seems a bit low to me.

i know that headshims has to do with heat, % of nitro, sea elevation and a whole heap of other things, but any advice?

i'm thinking to stick to .3mm shims just to be safe. anyone played around with putting shims under the sleeve to changing the timing?
and if your seriously thinking of playing with crank timing by shimming start with an engine that sucks lol. IMO.

cheers,

All .12 Nova Rossi engines, including the MAX and JP comes shimmed for 16% nitro fuel, which is .3mm, it's an aluminum shim.

So its safe to say .4mm would be correct for 20%?

If you want to be sure check the squish by putting a piece of solder between the piston and headbutton, a safe squish for a nova engine is 0.5-0.6mm any lower than that and you have a high change for detonation.

I would check it first before running the engine, despite people overhere saying it's safe with .1 mm
If the engine is new, first heat the engine and then give it a full rotation with the piece of solder in place.
