Like I mentioned in a different thread I'm finally getting around to fixing my RC51 after the previous owner broke the drive chain and subsequently the case around the countershaft sprocket.
Historical perspective: When I bought the bike it was presented and sold to me in "mint" condition before I became a member of speedzilla. Who would think to strip off the bodywork for inspection before purchase? The damage would've been hard to notice anyway. I discovered I was ripped off when I went to replace the drive chain which had a dirt-bike master link on it. After I joined speedzilla and started asking for help, Roningsr put 2 and 2 together and realized the dude that ripped me off was a member here and had posted about his problems prior. I tried to prosecute the crook but was ultimately unsuccessful. Lets just say I discovered the difficulty of going after crooks in their home states, and to also never underestimate the willingness of local police to hassle outsiders to protect "family." After that the bike sat for a quite awhile until I learned how to weld aluminum, and I then got the idea to fix it as shown below.
Here is the first thread from before I was a member of this forum or even interested in buying an RC51.....where member rsxjosh broke his chain doing 75 mph.
Chain broke while riding. Clutch problems...
Then he posted this thread where he tried to dump the bike:
FS: 05 Rc51 (needs left crank case)
But then he disappeared. I now know that he cobbled it back together with some all thread barely engaging the remaining threads. It was totally unsafe.
Last night I finished the repair on the motor and thought you might like to see some pictures of how it came out. It's not super pretty, but I think it is a solid repair that is probably stronger than the original section damaged.
Unless you guys tell me it's a complete waste of time, while I have the motor out I'll probably check the valve clearances. Also I'm waiting for the pair blockoff plates I made to come back from the anodizer, but otherwise I can't wait to get my motor back in and RIDE the damn thing!
A special thanks goes to SubSailor. His suggestion to use TimeSerts instead of heli-coils was excellent, they work great! I measured out the holes/threads on an ebay case I have here and then decided to use the longest available 19mm (6mm x1.0) inserts to obtain the same thread engagement as Honda initially had. Something not possible with heli-coil!
Here's the before pics:
