if you do that, you will want to keep your gearing as the motor will pull at a higher rpm than what you currently have, so say right now your pulls from 4-10k rpm shears will pull from 6-12k for example not actual numbers. so you will need to keep the gearing to get out of the hole and it will top out at a higher rpm.

Did you finish the race on a wheelie? ;-)

4 snow are working pretty good....In the snow....

i have the 15-41 setup and it pulls hard but still has enough low end for some trail riding.

Anyone running the Elka linkage with a longer shock made by a different manufacturer or is it a proprietary combination? I called and talked with Wayne at PEP and he didn't have any specs on building a shock for that link. I Like the idea of more travel but not interested in running an Elka shock. Curious if anyone has had one built.

Ive ran r50 forever. Im a fan of all klotz oils. From my experience most of the time build up comes from poorly tuned motors.

AND for the record bub. Pulled head off and obvious compression leak into coolant port was found. On left cylinder. After further inspection, cylinder head itself was flat, except for a small raised portion right between a coolant passage and the combustion chamber. Half ass machine shop in town. SO in other words, if the piston is above all the ports in the cylinder, and the rings are healthy to pass a leakdown test, then the pressure will infact stay held in the cooling system. Bought a cool head. Problem solved

15/39. If you hunt real hard you may find a 38 rear for the 6 bolt style. Any more top end then that and you'll have to try a 16/41. Can't really see the typical 4mil wanting to really pull a 16 tooth front though but it's probably doable.

congrats rob u won didnt u?

there should be a 45* angle at the top of the head stud holes, 1mm (1/32" or so) deep if the top of the threads just ends with a jagged type burr the torque from the nut could pull the top surface up and create a leak.
