    compression values

    Part of it could your compression gauge. I've got a nice cheap one that works great but always reads ~30% low. As long as I don't mind doing a little math in my head it works fine. I've retested it against high dollar compression gauges over the years, and it seems to be staying pretty...

    Where the H3ll is the cam chain adjustment?

    Take a look at: http://ep.yimg.com/ip/I/dratv_2058_87337615 some have a locking screw (like on the other Hondas you mentioned) and some just have spring tension. The plunger and spring are under the cockeyed plug on the bottom left side of the engine cases. The straight plug on the right is...

    Stripped Spark Plug Helicoil?

    It's a 10 x 1mm pitch. If you've got a competent dealer near by it might be cheaper to have them install it instead of buying the kit, but if you can find a kit, installing Helicoils isn't too tough a job. I think the part number for the 10 x 1 spark plug kit is 5523-10. -kevin

    Clutch problems

    If the RPMs drop off when you pull the clutch lever in, it seems like it must be because something is putting an abnormal load on the crankshaft. Does it happen in neutral as well as in gear? I think the first thing I'd check is the bearing in the middle of the clutch cover. Apart from that...

    72 CT90 restomod help

    Std bore on CT90s is 50mm (1.9685") Std piston-to-cylinder clearance is 0.01-0.04mm (0.0004-0.0016") Yes, that's 4 to 16 ten-thousandths of an inch, or roughly half a thou to a thou and a half. Compared to most other internal combustion engines they're tight little buggers. If you buy a...

    guide seals?

    On CTs, they only had a seal on the exhaust valves up through '79, but they added a seal on the intake valves in '80. They're not quite as critical on little horizontal engines as they are on big vertical engines. (or American V8s) I've seen plenty of 50/70s that got put together without the...

    Exhaust question Need quick answer before i order!

    It'll probably fit, after a fashion, but since it's for XR/CRF50s it's probably going to be a little bit short. And, that nice round can is going to be next to the shock, so it's going to stick out in space a ways. Still, if you love a challenge and are confident in your fabricating skills, go...

    Now at Canadian tire

    Great price, . . . if it's a decent little bike. I hope they're offering it in different colors, tho'. -kevin

    fuse

    I wouldn't be too worried about using a 10A fuse with that harness. The alternative is to install a smaller fuse, like a 5A and give it a try. If it works then stick with the 5A fuse otherwise jump up to a larger one. -kevin

    He can borrow mine, . . . the one that has a few "quirks." (It's the natural motorcycle, . . . the closest thing to walking!)

    fuse

    The 12V electric start Honda C70s used a 10A fuse, if that helps. The main reason the fuse is there is so your wires don't turn into fuses. I suppose it wouldn't be too tough to figure your full current load and base the fuse size on that, but as long as none of the wires are smaller than...

    It's a deal. I'll bring a bunch of my favorite Red Angus ribeye steaks while I'm at it, . . . or maybe some good ol' southern barbeque. I dunno about saving the world, but we all know the secret to making it a better place - now all we have to do is convince all of the world leaders to get...

    please help, electrical question

    If there wasn't any "custom wiring" the rectifier will isolate the battery from the stator, protecting it from damage. It should just blow your bulbs. -kevin

    Y'know, I really don't know about that one. However, my daughters assure me that "anal-retentive" does have a hyphen. That's not fair, though, . . . their mother coaches them to say things like that. <HA>

    Sorry, . . . slow response - The boss called Sunday after lunch and all I can say is Fuchsstadt is lovely this time of year. (The one near Hammelburg, . . . yeah, that's Hammelburg, Germany. And who would have ever guessed that there'd be more than one Fuchsstadt??) Being there for a mere 36...
