1973 XL175 Vitamin C Hell Ride
« on: Mar 15, 2014, 22:14:43 »
I was looking for a small, vintage and street-able dirt bike when this thing kind'a fell into my lap.



It's still up in the air as to what I'll do with it, but for now I'll just see what I can do to get it running. The first order of business is to deal with the kick starter shaft. They commonly broke at the set screw groove.  A donor in Charleston came available on eBay, so the wife and I took the kid for the day to get the bike, see the aquarium and get some good Charleston vittles.  I payed $100 for the donor bike, which seems like a steal considering kick starter shafts are often $150 when they rarely come up on eBay.

I started tearing down the good bike's engine to pull the broken kick starter shaft.  According to the Honda Service Manual, you have to completely tear down the top end and pull the top case off of the bottom case, and transmission, to get to the shaft.  I recall a conversation with Murray(cxman) where he said you flip the engine and pull the bottom case off.  For some reason I went by the service manual procedure, which is essentially a complete teardown.  I suspect the conflict in approaches has something to do with how the transmission is set in the case and how it meets up with the engine.  As I got it tore down to the point where I pulled the cam (valve springs were next), it occurred to me:  I really never intended to tear this thing completely down (not now at least).  Also, the parts bike engine will turn over.  Why not try to use the parts bike engine in this frame?  Genius, right?  So, now to pulling the parts bike engine.  If there's anyone out there that knows this bike, and knows if pulling the bottom case off the engine while leaving the top end in tact will work to get to the kick starter shaft, please let me know.  Otherwise, it's strictly by the book... at least for now.

Pulled the motor from the donor bike.  Took the side covers off.  15 case bolts (8 on top, 7 on bottom) later, a couple taps with the sledge and wedge, and she cracked right open to reveal the glorious kickstarter shaft.  It really was that easy.  No idea why the fuck the Honda Service Manual tells you to completely tear it down. 



On a side note: I must remind myself next time I buy a donor bike mostly for engine parts, to take the engine out first before I have bright ideas that involve taking the front end off the bike.  Moving an otherwise complete bike around with no front end sucks.
