    I plan to do a complete gear box rebuild next winter, but want to get parts on order before then. In particular, I need to order parts to fix the current problem which is:

    The kick start pawl is not (usually) engaging the first cog on the gear, resulting in a 2/3 stroke when kicking over. Obviously, the pawl and pawl spring should be renewed, but what else In the kick start assembly?

    I want to ride the Atlas thru the summer and fall, tackle the project in the cold months, (usually Dec to Jan here in Texas), and want to have the parts on hand. I already have Mick Hemmings layshaft bearing, and plan to order the bearing/bushing/seal kit.

    Does anyone think the first gear cogs may be worn, resulting in the kick start problem? Any other parts I should have on hand before opening up the GB?

    The pawls wear more than the inner teeth of 1st gear but you really have to take a look before deciding. If you opt to change 1st gear you could consider going over to the higher 'Daytona" ratio that RGM offers. I fitted this to my gear box and I am happy with the smaller gap between 1st and 2nd.

    I would also do the springs and the pin on the pawl.

    Rebuilt my box this winter after 40 plus years of use, you should be ok just changing the spring, pawl and pin, but until you open it up ?? Got my kit from Norvil. I had to shim up the end float on the kickstart as over 60 thou which i thought was a bit excessive for the layshaft superblend. 450 miles now and no problems.

    My Atlas is very happy with a 21 tooth GB sprocket. I used a 20 for years and glad I switched.
