A few tips needed with my B-max4

[CODMAN]

Hi guys, this is the first (of what will probably be many) requests for advice on my B-max factory team build. I've got 2 questions for the moment:

1- How tight does the motor bracket screw (the one with the spring on it) have to be to keep the motor from slipping free? Do I need to crank it down? Or just slightly tight?

2- Diff shimming... Ok, I've read through the posts here about it and am still wondering a few things. There is talk about an alternative method for shimming found in the manual, but in my manual (the factory team) there is no mention of how to shim! They just give the recommended numbers of shims... that's it. So is there an alternative way to shim it? So far, the manual settings (1x12mm shim on each side, and 2x8mm shims on the small crown and shaft) seem comparable to how I used to shim my B44. That is Slightly tight with a bit of binding. The gears would then bed in after a run or two. Do the Yokomo gears do this (they are a different plastic than associated)? Should I trust my experience and do it this way (which is what my gut feeling tells me)? Or try to shim it free.. The last time I shimmed new diff gears free in my B44, I toasted them in 2 runs!


Any input would be appreciated on these subjects!

Cheers!
