I do have parts books and service manuals for the many models of Bultaco.  Suppose I could always scan a picture or two... or more, if needed.

Thanks for getting back bullylover, last night I put it back with 5&5, I didn’t have time to finish it but I’ll let you know what happens. 
    It definitely looks better and feels good.  

Doug, maybe a diagram of the clutch and mechanism would help especially with part numbers. My engine number is JM-199**** thanks for offering.  Mel. 

this is her.  
 

Melbutcher:

The latest parts book I have for the Sherpa T 350 is model 191.  I was hoping it showed more info (number of clutch pates), but I can post it if you're interested. I also have the model 203, but the Metralla could be slightly different in the clutch area.  Nice looking bike & MG.

Some clutch related pages from the service manual.

Thank you Doug. 
    Some priceless information here, I’m going to print it off and save it for myself. 
   I did put it all back together with 5 drive and 5 driven plates and lo and behold it runs around the yard beautifully, 

Mel.  

You're welcome, Mel. Glad to hear your bike is running great.
