NEW 45 engine

[ALLAN YUEN]

Look list part no clip holding replacement top hex screw at front housing with two bearings then Choice two different optional : flywheel DD or gear drive

 

[normlee]

There is no clip holding the bearing in the housing, push on it if you want to.

Are you saying this engine is ok for collet drive?

 

[Timbo Whalen]

I talked Tony Australia about 91 m-line it can use both collet and square. Not arrive new CMB45 M-line yet because factory workers delay from Covid-19

45 will run collet, too.... Tony will have them in mid November...

This was from Oct 9th-

 

[Timbo Whalen]

Are you saying this engine is ok for collet drive?

Yes.... direct drive....

Dad and I just ordered 1 each. Looking forward to seeing this thing go. We've got the 91 M-Lines and fell in love with the 45 the moment we saw it.

 

[timothy johnson]

So with all this is there going to be a M 1 kit available for us to purchase for the gold head 45 rs?

 

[dr gary turner]

[timothy johnson]

Thanks Doc, all we need now is some races.

Jake I wonder that did you see disassemble front housing for CMB 45 M-line. Which one cage bearing or needle bearing onto the front housing near cone with flywheel ? Can you show us picture of your motor open ? Thanks

 

[Alan Elzer]

So what's the difference in the motors from gold head to m 1

 

[Buckshot]

Took mine apart for the first time last night, you can push on the crank.

 

[dr gary turner]

Alan if it is like my 21 M1
Dish piston and turbo head

 

[ALLAN YUEN]

Show any pictures of crank????

 

[Alan Elzer]

Whats that mean (push on the crank)?

[David Bryant]

There is no clip holding the bearing in the housing, push on it if you want to

similiar issue as on CMB 27 Alpha-EVO engines ? (must run square drive)

 

[Alan Elzer]

Is that a bad thing

 

[David Bryant]

Is that a bad thing

I don't like it. But using a square drive remedies the situation (by allowing the flex shaft to "float" within the coupler, and not push up against the crankshaft, transferring the torque to the rear rotor assy)

 

[dr gary turner]

I like the 91 M1 motor
I ran a pair in a twin at Brandon this year
Out of the box the performance was quite good.

There is 91 M1 and 91 Inline. The 91 inline appears to have the M1 features

 

[Alan Elzer]

So on the 45 M1 any difference in p/sleeve or porting & timing numbers from gold head
