Title: 125 B motor tranny oil capacity?
Post by: bentrims on September 27, 2006, 12:40:49 AM
Easy question for most of you; How many cc's of tranny oil to refill a B motor?
Thank you,
TomB.

700cc [^].  Didn't you read the letter from Master Doug??  Doug actually likes his riders to read his letters;).  Give me a call when you have a minute.

Thanks Ron,
I know its in a file somewhere and remember Doug telling me most people overfill and get leaking from the shift seal. This was easier than trying to find where I put it.[:p]

One more thing;

My Sachs came yesterday and it is an "A" motor freshly rebuilt (claimed). How different is it than a B?

Tom,, an "A" motor has heavier crankwheels and milder porting, to put it briefly. They work great in trials bikes.

The "A" motor may be the best true vintage "woods" motor ever built.  I love the one in my Berkie.

Thanks for the info guys;

Hmmm, I hoped to turn this into another high rpm MX motor. Do you foresee problems? Should I save it and look for another B?

Past experiment stories greatly appreciated.

Tom,
  Lew is correct on the flywheel weight and size.  It has less of a stuffing effect that a B, B (GS), and a D (which could also be a GS), but that also makes it better, in my opinion, for oiling.  And once you get mass moving on a small bore the bigger flywheel really makes it nicer to go into turns in a higher gear with great RPM momentum.  Is the engine a 5 or 6 speed?

Maybe after the 8 motos[xx(] it gets hammered on this weekend at Moberly a tear down will be in order.

Remember it is a Six Moto Penton.  Don't be hurting my sweetheart.  I see it every year in Texas.
