yes i used other egines from GR.
Rex 3/5port, novarrossi NSR 5, LS3 etc on..
But i did not try novarossi Plus, 353..
and i quess OS engine had more modified effect than novarrosi.
( this is my quess
OS normal 100% power -> GR modified 150% power
novarrosi normal 100% power -> GR modified 130% power.)
i showed RRR with os speed specII in last weekend.
But RRR did not catch me in top speed... (i used GR OS 12TZ 3port)
Is the crackshaft black coated?
-> yes.. But now.. only coating in crankshaft head by GR Racing
and.. the crankcase is os 5port crankcase (OS coated)[/QUOTE

i always used novarossi 2630 pipe (5mm)
and i tried GPX 6mm pipe in recent days.
But for too much torque.. i could not drive stable in corner out.
so i changed to 2630.. mild acceleration and awesome top speed was good!!

Mind you, once modded, it might be a different story - do you find these easy to tune? (OK, I know you'll be biased - you're sponsored by them
) so don't need to answer that.

Thanks Gansei, I'm tempted because its OS-based ... I like them because they're so easy to tune and just runs and runs.

enough mixture setup also is needed..
pls use 0.3mm head gasket in break-in course
and use 0.2mm head gasket in Fuel nitro 25~30
and use 0.1mm head gasket in Fuel nitro under 20%
i used GR OS TZ (0.1mm) in 2007 FEMCA..
