I'm thinking about getting ceramic bearings for my TM728, but I can't find the exact diamensions of the bearings.

Your help will be appreciated.

Ceramic bearings for these type of engines is overdoing it, better spend your money on a TM928 and you will notice the difference.

I have about 1 gallon on my TM 728, and the front bearing is leaking a lot of fuel. The engine has been running between 200-220* since breakin. Some people I know say it's normal, others say it's bad. As far as I can tell, w/o removing the flywheel, the sheild is intact. Should I replace the bearing(s)? Is seepage normal? When I finish running one tank of fuel, there is a line of fuel that has been sprayed on the pipe from the spinning flywheel... I think the seepage is a little excessive.

If I need to replace the bearings, I would like to get ceramic ones... But I will need the exact dimensions for the bearings.
