Keep off 4/4bttwc head shim
I'm running both engines with 41033/41032/41031/41021+2096, is it possible to run 0.6mm or 0.7mm head shim to gain more bottom, always on c5gtn plug, please advise. Thanks in advance

i usually run the .80mm until engine "drops its nuts" then go down to .70mm running 30% nitro on all my FUSION X engines which are pretty standard old 16.26 x 16.80 bore x stroke combo .. they run awesome

you can run .60mm shimming on head button if you want .... i wouldnt recommend it with 30% fuel or on a newer high compression engine but on 25% or less and well broke in ... should be good

.70mm is perfect for 30% on the fusion x engines with head button 28028 after the "DIN's" ...
.60mm shimming is pretty tight quarters for 30% ... at .50mm the piston will hit the squish band area of the combustion chamber if there is any slop in the rod
hope this helps
Merry Christmas to all.... and a prosperous new year

i request my engines to be shimmed at .80mm from novarossi .. two x .30mm and two x .10mm .. this way you can remove a .10mm after a while ... still use 30% fuel

Hi Monty
Got great deal on a Brand New Bonito.
Looking to put in a MP9 /Truggy
What is the best pipe/header and clutch of this motor?
And any other tips for shimming etc.
Many Thanks
Tom
