Thanks looker,any idea on some ceramic bearing kits & seal? Make a difference Worth doing the rebuild ?

From what I understand, ceramic bearing are not good to use on engine crank shafts.
I would suggest new Zenoah bearings, and stock seals.

Ceramic bearings are over rated and are high maintenance.

Have read sufficient horror failures from other setups using them.

Just installed the 29cc head kit and the difference is like night and day!! I love it!

Did I read that right?

This is a direct bolt-on upgrade for the 2-bolt engines that come stock on HPI Baja, Losi 5ive, Losi Desert Buggy XL (DBXL)...

Yes. 2 bolt is correct.
