case stuffing..

concentrate more on port sizes, timings and geometry before worrying about crank stuffing. get more in with less turbulence and pressure.

personally im starting to contemplate unstuffing the thing by removing the weights altogether, and machining the excess away from round the crankpin to an old school T crank... thats just me.

jb weld seems to be the cheapest option. cheaper than 100+ a tin for real stuff.
 
If the engine is apart, then the most simple modification is to stuff the crankshaft counter weight holes with some light weight material as this will reduce crankcase volume; boosting crankcase pressure.

At this point in time i haven't had the need to find more power, with the R.S.E. reed valve intake satisfying my requirements for improved low and midrange engine torque.
