A little BD present to myself. Picked up a ‘72 Yamaha R5 (RD350) for $120 from Johnny’s Vintage MC Akron. Mostly they specialize in KZ900 restorations. Got a few pics of the shop and the really rough R5. It looked like it was laying on its left side in a field for many years. As it turns out, it was used in the Kamikaze Jumps in Ashland, OH and pulled from the bottom of the lake after it was jumped! The goal is to ride it before summer. Either this or the KZ750B, another vintage project. Will update!

Update on one of the barn find Z50’s (1984) it was in far worse shape than the ‘78. It was missing exhaust, all bodywork, fenders, gas tank, seat, carb, controls, even handlebars and top triple clamp was missing. Transmission was locked up. All electrical was missing, rims were rusted completely through, tires dry rotted. Chain seized and sprockets trashed. I’ve had fun putting Amazon parts on it (throttle, grips, kill switch, carb, air filter, fenders & gas tank. Seat was from Glens surplus. Iron pony for the chain & sprockets, tires, and OEM gaskets. The 1978 was 99% complete. It was missing the lights, and a few brake parts. The tubes held air and it just needed a carb clean and piston / cylinder and it’s done. If you look carefully you’ll see in the background the new project a 1998 Z50! Picked it up in Amherst last Tuesday, was excited to meet another collector and he threw in a lifetime supply of parts, even a Chinese quad and a w**d eater (was doing some spring cleaning). Last fall when I rode the ‘78 for the first time I enjoyed the challenge of the 50cc (not a lot of power but manageable with gear selection and RPM’s) once I got “adult” handlebars on it, then I could actually steer it and son of a nutcracker that was so much fun on my minibike track in the woods!!! Looking forward to mid-Ohio vintage weekend this year, my goal is to have 4 pit bikes ready for that event. Not to race but to just ride around non-stop and have fun with friends.

More “FUN” projects! Old man Ben picked up this once fully chromed but now rusty minibike with a mint condition seat! We’re going to install a Robin OHV slant cylinder engine, fired it on carb clean. We ordered a new carb, old one was pretty bad. Should be riding it by next week. And for the red Z50…. After installing 5 different coils I finally realized that points must have their own coil, I installed one from a similar model (CT70) and solved that mystery. It now runs, but wouldn’t go into gear. Pulled the engine and took the clutch cover off thinking it was shift detent. Detent was fine, but The shift drum was frozen. On the left side case there’s a rubber plug. Under that plug is a bolt and washer that goes into the drum. The rubber plug had allowed water in and rusted the washer and bolt to the drum. Removed & cleaned now it shifts nice snd smooth. Sadly I’ll be waiting on the clutch cover gasket now. The gas tank, fenders, carb, air filter, brake cable, grips, twist grip & cable, kill switch, steering nut all were Amazon parts! The seat and rear shocks were Glens Surplus parts. Handlebars off an old Kawasaki street bike. Handlebar clamps off a Honda ATV. (Stock bars on this ‘84 model are not adjustable and impossible to steer with) exhaust is a GP style Z50 exhaust I had laying around (not good for off road no ground clearance) Bill at B&B gave me the stock seat and shocks which will end up on it eventually. Seat will need completely redone and I fear that the rear shocks might be too soft. I want the two Z50’s I have to be pretty close to the same so it will be a friend challenge bike on my minibike track in the woods. Maybe Lap times 😅 or a hill climb bike for Jamie’s broke-foot impossible hill climb 😂 possibilities are endless. Ultimately seeing all the thousands of people at Mid-Ohio on minibikes inspired me so here we go we no longer have to be spectators we can be participants. Z50’s are a challenge to ride - lack of power makes gear selection priority! If there’s a hill you better have a game plan!

BARN FINDS!!! 1978 Z50 (near complete) 1984 Z50 (engine wheels frame) and a 1959 CT50(I think it’s a CT)
1959 missing valve cover and kick shaft broken off, rims rusted through it’s in real bad shape.
1978 Z50 chain froze, missing front brake parts, points not opening (no spark) and someone mushroomed the end of the crank trying to get the rotor off without the puller, low compression, carb gummed up but clean tank, rear brake frozen, tires flat.
1984 Z50 besides the missing parts, rims rusted through, super low compression 50PSI, and trans seems funky may be mis-adjusted clutch or something.

1959 being sold for parts. 1978 everting has been fixed & replaced, it’s all there now, and the cylinder/piston is on order. 1984 is now a parts bike.
