Does anyone know if you can upgrade the 50 cc engine in the LB50 Chappy to the 80cc engine? My dealer doesn't seem to know either. I've got 78 LB50. I can see that the connecting rod is the same part number between the 50 and the 80, so I'm betting that it's just the bore that's different, but does anyone out there know? Thanks in advance...

I don't know if it's normal either, but my 78 LB50 works the exact same way. Just seems to "ooze" into 2nd gear. I'm going to guess that it's normal. I used to be around a 80 Chappy, and it was not like that. Sorry I can't be of much help here.
