<< Hey fellas I've got my turbo R1 one on the rode, but it hesitates at
 around 8-grand and wont pull any higher while under boost.  I brought it
 into the garage and revved the motor the way they do it on the dyno, and
 I noticed that it would rev to about 10-grand and then drop to 8-grand
 again. I also noticed that the temperature climbed faster than usual so
 I turn it off. The bike came with 130 mains however I installed 140s.
 About 6 months ago I think I read shammars message stating that his bike
 or someone he knew had 180s. What do you fellas think. >>

Did you use an Air/Fuel gauge?
My bike came stock with 190 mains.After the headwork and misc. stuff we ended 
up at 215 mains.Now with the turbo and 950cc kit I am at 230 mains but I dont 
think that the jetting is correct it should be much lower.
The bike running hot could be an indicator of both the bike being too lean or 
too rich.I spoke to Mark Moisan once and he said that the R1 turbo does run 
hotter then usual.
Best bet if you dont have the Air/Fuel ratio gauge is to either install one 
or find a dyno shop with an EGA.
