SafetyBob Posted June 20, 2021 Report Share Posted June 20, 2021 Gents, I was just gifted for fathers day, a CJ OHV engine and transmission. I have not seen much info anywhere on these OHV models.. Anyone have any idea where to look or have any of the Nipper faithful tried to insert one of these gems into a MT-11 or MT-16. Might be a fun winter project to get another bike rolling from the parts stash. Is there a service manual for this jewel available online? Sorry for the banter...

Scott E Posted June 22, 2021 Report Share Posted June 22, 2021 Here's an online parts manual for side valve and overhead valve CJ motorcycles. Parts are also available from the same site. http://sidecarpro.com/Parts_manual.html Quote Link to comment Share on other sites More sharing options...
propwash Posted June 22, 2021 Report Share Posted June 22, 2021 I believe the engine and tranny will bolt in. You may have to monkey with the drive shaft length if the engine/tranny combo are longer or shorter than the original setup. Keep us posted.

arbalest Posted July 14, 2021 Report Share Posted July 14, 2021 The motor is WAAAY better than ANY OHV Dnepr motor. Electric start with over running clutch ( can't hurt anything by hitting the start button with the engine running). The Dnepr transmission is better, but the whole thing bolts in. Using the Dnepr transmission means no driveshaft issues. You just need to find a button for the starter. Quote Link to comment Share on other sites More sharing options...
SafetyBob Posted July 18, 2021 Author Report Share Posted July 18, 2021 Sweet. At first blush, the casting quality is much poorer than my Dnepr's . I would offer the quality/fit/finish overall seems to be less than my early KMZ engines and tranny's. I will have to see how it holds up to pulling a MT-11 rig around. The electric starter holds some glamour to me as I age... My goal was/is to have a backup powerplant for when I can't get KMZ bits anymore. Right now I have stock of OEM pistons, heads and ring sets to last me and some friends for a few years. Again, the jury is out for a year or so till I can bang it around ... I really doubt a Chinese copy of a KMZ reverse engineered BMW will give the service that my KMZ power plants have. The KMZ engines have treated me well... If they just had a reliable E-start.... For those folks that have texted with questions; my little fleet is doing fine; only have one URAL now, the rest are KMZ. I am looking to add a PATROL or GEAR UP in a year or so. I feel that I will need electric start machines in a few years to keep this hobby going into my golden years. The oppressive heat here in the South is playing heck on boiling the crap gas out of the K-65s and Pekars on the Nippers. Its just to hot to putt around at low speed and expect the engine to cool properly...Reliable, hot re-starts take several kicks to roll them over after putting around. Hope everyone is doing well.. Can't wait until winter... Stay Safe, SB#3 Quote Link to comment Share on other sites More sharing options...
