post number 137
OH SHIT! I fired up the sears around three oclock today and it ran so great. I blipped the throttle and my oil pump drive belt flun off. I retarded the spark and killed it as quickly as I could andshut it down. Ray noticed that my primary chain didn't line up with my clutch. I put the bike on the lift pulled the chain and pulled my sprocket out like this! Man oh man this is unfortunate. Apparantly we picked the wrong metal for the sprocket shaft and pulled the threads. Luckily my cases are not damaged and I have a couple spare motors. I am going to convert it back to a stock set up and run it with total loss oiling for the run. between designing prototyping and brain storming our team probably have 12oo hours invested into converting the spacke motor to pressurized oiling. I am not giving up on a recirculating oil system but rather just putting it on hold till this winter
here is the keyway for the sprocket shaft. I think that I am going to try having some one piece flywheels made up this winter to avoid any problems like this. it is very unfortunate and the timing couldnt be much worse, I am just thankful that I have the spare parts to get it running again. This motor sounded unbelievably good before it let loose. I wish I would have recorded it so you could hear it too! I cant wait to have the stroker motor set up again.
here is the bottom end coming apart
pinion flywheel off, check out the sprocket hole lol.
there is the nut and some metal shavings in the bottom end. eak. It would be pretty easy to get discouraged or upset by this, but there are a lot of positives, 1. This happened at the shop 2, I have a week to put it back together and ride it 3. It didn't happen on national television 4. My cases are not damaged. 5. it happened on a thursday and I was able to find pistons and rings in time to get them overnighted to our shop and not have to wait until monday for motor parts. Etc etc
I am sure there are more, but they escape me right now. It will all work out and I will have my cannonballer bike. Wish me luck I need it more than ever.
