The MC-1 is suppose to be specifically formulated for vintage 2-stroke motorcycles. It sounds lean but MC-1 is formulated to be run at 50:1 and Bel-Ray recommends against running it any heavier. I haven't ridden the bike enough to formulate any kind of opinion yet.egawa+zbrykhttps://www.blogger.com/profile/15673821117250940790noreply@blogger.comtag:blogger.com,1999:blog-1527633089134060263.post-50500208458000324922012-10-05T13:10:57.541-07:002012-10-05T13:10:57.541-07:00What type of gear oil did you use in the engine ca...What type of gear oil did you use in the engine case? I've heard different opinions on the type/weight to use on these older engines. Modern oils have additives that improve lubricity that weren't avail in the 50's-60's, and could effect clutch function. As far as gas/oil mix, 32:1 synthetic would probably be safe. The original manual called for 20:1 !<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1527633089134060263.post-14257112809000115212012-10-04T16:25:32.128-07:002012-10-04T16:25:32.128-07:00Yes, it did not belong in a Csepel.

The original plates with cork were wore quite thin and I guess somebody used the bakelite plate as a spacer. I just got a new set of clutch plates in the mail today, so hopefully I'll have it back together in the next day or two.egawa+zbrykhttps://www.blogger.com/profile/15673821117250940790noreply@blogger.comtag:blogger.com,1999:blog-1527633089134060263.post-60006905944739549312012-10-04T12:36:10.705-07:002012-10-04T12:36:10.705-07:00The clutch material seems odd, they are made of co...The clutch material seems odd, they are made of cork on my '60 danuvia 125.<br />Anonymousnoreply@blogger.com
