Powerseal does beautiful work as well.

Heres where the bike is at

Yes it's in my kitchen & yes its a work in progress. You can see the tank on it at this point but the shrouds still need to be attached.

The 91 jug needed some port work to smooth out the powervalve area & the powervalves had to be relieved as I went 2mm overbore

You can see the rechambered head above as well & below here you can see how the everthing is flush when the valves are open, they were 1/4 inch deep before the work.

The RMX is know for having excellent fuel economy due to such a small exhaust window, you can kind of see it here when the powervalves arent open
