I know exactly what needs to be done, the reason why I did it, was to check how Sirio based set work in Nova case, but I use Nova based rod and it is 0.5 mm shorter then has to be. BTW All parts I am using is only made by me.

Higher all ports at the same time(not only exhaust height). I have tried this way before.

Considering the track for WC in Brazil, there are absolutely no compromise between both RPM (because of the long straight and high speed sweeper) and torque because of track elevation.

0.3 mm height change is 6 degree difference on 12 engine, it will not chnage a lot, it will defenetly add top speed in exchange of little bit bottom end-one of the modding for particular track (high flow tracks)

What about it's fuel mileage? Is it better or even worse when you do this type/style of shimming? Thx

i allso had the red silicone come out and sent the motor back to mugen usa and it took over 3 months to get it back, yes the motor screams and yes i put in the ceramics in myself,both front and rear,i don't recomend the fronts as they only last a few races,the older style cases with the large front bearings will last a long time,i have had them run all season with no problem

I agree with you. The front ceramic bearings seem to have problems. At least the Boca ones... Perhaps it has too tight tolerances. I don't know if the JP FX engines have BOTH ceramics for the front and rear. If they do, then they somehow perfected the art to put the front ceramic bearing without anybody complaning about bearing failure...

i have trashed more engines the front balls disintegrate and go thur the barrel and take the case , crank , piston and sleve. it only takes a second to happen and its gone. i also think that the mtx 3 shifts so violent that it help the front balls in any motor go away the new motors have the small front bearing and that is another problem
