I love the old Motosport. Honda has never built a better looking bike IMHO.

Howdy all!

I just bought a couple bushel baskets full of parts that are supposed to be a 1974 XL 125. The engine is half in a cardboard box and the other half is in a beer flat. 4K on the odometer and valves at least look good. The engine had set and the piston froze in the bore but looks like it should clean up OK.

The parts are in pretty good shape, and I've been mulling around about what to do with it, either a full resto job or just make it into a nice little bike and I believe the "nice little bike" approach will get the nod. That way I can have my kids help me build it and then they can all learn to ride on it and I won't freak out when they run it into the bushes like I did when I was learning to ride.

Anyway, can I get some suggestions of places to order parts from nowadays? Mainly looking for engine partls like rings and points, but haven't done a complete inventory on it yet.

Thanks!

Parting out complete bike that was running. engine had some top end noise and smoked when first started; probably needs valve guides. everything else is in good to excellent condition. email me and i'll send pics and we can negotiate price.

Kind of a sad XL story, but here goes.

As a kid, there was a kid in the neighborhood who used to ride around with his dad. Kid on the XL125, dad on a XL250.

Fast forward a decade, that kid turned into my brother-in-law. The XL125 was in the garage...rarely used as it didn't run. He took it to several shops who said "...it'll be too expensive to fix it, we'll be happy to take it on trade..." He always brought it home.

After three kids with my sister, and just after moving into a new, larger house, he was killed in an auto accident.

A year later, my sister sent me a message and said "...can you take the Honda? The kids are crawling all over it and I just know someone is going to get hurt..." I drove my old '71 Dodge D100 and picked it up.

Not to go into details, but I bartered a deal with a local independent motorcycle shop to get the bike running. A week later it was thumping happily. 2200 original miles, a 100% original 1977 XL125.

It has been in my garage since. Every now and then I would take it out for an adventure, tossing the tag off my '66 BMW on it. Now NC makes having the wrong tag on a FELONY. I e-mailed my sister today... time to get papers for it. Hopefully she can surface a title...

Might be interested in the motor, where are you located?

1983 Honda XL600 engine with Wiseco high compression 102.4mm piston that had another 26 grams machined off the piston. CR was around 11:1 from memory. Cylinder head mods comprised of a port job from Ballard's XR's only. Camshaft is a White Bros track spec unit part no. WB1610. This cam necessitated the fitting of shortened bronze valve guides and stiffer R&D valve springs. Titanium spring retainers and new hard chromed intermediate rockers. Custom-made aluminium manifold for the two 34mm TM Mikuni flat slide carbs.

Ti-7Al-4Mo specification custom titanium con rod with increased the wall thickness at the little end to prevent the stretching problem experienced with the stock rod. The big end was fitted with a pressed in hardened and ground steel lining for the roller big end and an aluminium nickel bronze bush for the little end. The little end was honed to size and the rod polished and shot peened. Balance shaft removed and the balance factor of the crank maintained at 50% suited to the lighter rod and piston assembly. I've raced this bike a few times and vibes weren't a problem.

The exhaust configuration consisted of two separate 26" long 1.5" O.D. headers merging into a 2" O.D. collector and tailpipe. The engine produced 50 bhp at the rear wheel. Not big power but it was super reliable. I reckon that with a tuned megaphone exhaust and bigger carbs you'd definitely get more power out of it. A lot of supermono runners in the day would run 38-39mm twin carbs. The ignition is stock so there maybe more power with an aftermarket programmable unit perhaps? We ran it on Avgas 'cause you could and it smelled good!?

The chassis was TIG welded 1" O.D. x 1.6 mm Reynolds 531 tubing. This material was chosen for it's strength, ease of fabrication and resistance to fatigue properties. The forks are ZXR250 but not sure of the year model.
