i have installed the 17011 front bearing on pretty much every engine out there for guys , most comments are my engine has never ran this good and held its tune this good after the installation

yes the 6.3mm part is only the inner race

Hehe. I guess its: why is it a good thing NOT to run the LSN rich?

You will see everytime you break an engine in with excessively rich low speed needle you will blow out the front brng

Oil builds up in crankcase , when crankcase gets pressurized due to increased rpm the oil goes out through front bearing when crankcase is on sealed pulse of the loop

Kills the front bearing, and contrary to belief, it overheats the engine.
Engine will come in at 130c, because you're fat on bottom you're hammering the throttle all the time.

Looking for a bit of advice, been in nitro a long time, ran Werks mostly. I decided to try the Mugen Beat BT5 as ive always wanted to try novarossi. I followed my normal break-in procedure, Heat cycle, with good results. I have less than 1 gallon and very low compression when cold, like wont hold itself up sideways when holding the flywheel. I pulled the filter and had a bit of dust on the top edge of the venturi but nothing seemed to be inside. I pulled the carb and the backplate at the track and everything looks fine with no signs of dirt getting in... I also just recently had issues with random shutting off and troubles with my idle once warm. Tried new plugs, checked fuel line and gaskets, clutch is good also. I am assuming something must have gotten in for this low of compression with less than a gallon, I guess I am just looking for opinions on whether to rebuild such a cheap motor or simply write it off and just get another?? I haven't pulled the P/S so I cant say to what condition they are in so This might be a bit premature, just a little bummed on the new motor.

Sounds like you may have gotten some dirt or dust inside. I would pull the P/S and send it over to Ray at Rayaracing.com for a cleaning and resize.

You will have to break it in again but its worth the $25. Make sure your pre heating for break in and taking piston to bottom of stroke when cooling.

Ya know, totally forgot about re-pinching, never had to send one off but its pretty cheap to give it a shot.
