also it keeps wrecking clutch bearings within 15 minutes of run time and they are like bottom bearing is weled to the crankshaft .
this engine is really powerfull and absolutly flies but not sure what to do to get it better .
i know how to tune an engine reasnobly well and are stumped by it..
any help would be appreciated.
cheers

Hi Dave, I have this same engine (well the Team version) and I am also running the 9901 pipe with the 41029 manifold (Mugen version of the 41021) and running at 240 deg I am getting between 9-12 mins no problem. I am running a 1.0 clutch spring as with the 1.1 spring it was turning my clutch bell blue and killing my bearings also. On my MBX6 I am using the 13tooth clutch bell with the stock spur, be sure you are not running to crazy rich on the bottom as that would surely have you burning threw fuel like crazy.
