The classes I picked have been keeping me up at night - really, riding a 125 is what was kind of eating at me. 

I am not a small guy.  I am 6 feet tall and weigh 290 fully loaded to race.  I bent fork tubes and foot peg mounts last year from some of the awkward/hard landings I took.  Going into this I knew that the 125 was going to take a beating, but the bike I am building has the large RM shock and the 43 mm forks.  However, the little 125 cc motor was was going to be the ‘weak’ link.

The motor is no longer a concern.  I bought a complete 1979 PE175 motor that will bolt right into my 1980 RM250 frame.  This will give me a couple of advantages - mainly 50cc more in the motor, and all on a frame that I am already comfortable with!  This is also going to cut down on the fool around I have to complete to have a race ready bike for the end of March 2010!

I will post pictures soon of this PEM when I can!
