Thanks for the info..it is very ...very , hard to tell from a photo on ebay, however now that I know what to look for there does appear to be a difference in the mc 16 and 18 fuel tanks...the front seems a little elongated and almost pointed..I am lucky enough to have one, but would like to go a step better....
Have been buying parts from anywhere and everywhere I can get them... and just purchased the rare and discontinued 10mm OEM crank seal..the small one was easy to come by and I had already gotten one , but bought both as a package $ 200 USD..Yike ! I love this bike
Previous crank discussions were extremely useful while I was sifting through the adverts for a crank and more recently a case as well. The case was ever so slightly damaged in the engine failure , but it was scored right in the most critical seal retaining groove. Rather than risk another failure ..after I managed to purchase a serviceable mc16 crank , I decide to replace the case set. I am sure I have a positive lead on the proper case and will find out soon enough..will keep you posted on the progress.
