Something different here (MT250 inside)
« on: Nov 23, 2012, 13:28:11 »
So I'e been interested in cafe racers and vintage bike about as long as I've loved classic Japanese cars. So I finally ran across a cheap enough old Honda that I thought was interesting. It is a 1973 MT250 Elsinore (wait, a 2-stroke enduro?). I figure since I've never rode a bike before it would be a good project and since its small and light, a good learning bike.

Anyway the plans for it are as follows:
- Get it running
- Convert to 12v
- Get a title
- Lower it/repaint/different tank, seat, front fender (ditch the rear fender completely)
- Paint it (the tank/battery cover/front fender) red with a shit ton of flake
- Clubman bars (don't want to commit to full clip-ons because I'm a big puss, etc etc.


Not what you'd expect for a cafe project! I figure it should be a cool project for my first bike.

I like low things haha. See my car:



Anyway I got it running last night (for the first time since the 80's!) the thing runs perfect, I didn't have to touch the carb aside from cleaning it, but the clutch kinda sticks and it slips bad. Second gear is destroyed also. But I didn't crash into anything and it starts up first kick! Still needing a new ignition/key and battery and everything should work properly. Today I'll tear into the clutch and see if I can't get it to grab all the way. I found a new gearset and that should be here next week

Well the clutch lever was sticking so I pulled it out, turns out pieces of second gear had wedged themselves against it, so tomorrow I will crack the engine open and clean it all out really good and just look at all the internals. So because of that I will strip the whole thing and paint the frame with some semi-gloss black. Maybe strip the tank and hit it with some red. Definitely clean the rust off of the wheels while I'm at it.

While you've got the engine apart it wouldn't hurt to replace all internal seals.

I don't know anything about the Elsinore, but it's a two-stroke and Steve McQueen rode one:



That's good enough for me!

I cracked that engine open and decided it wasn't worth the money in a new clutch gearset, gasket set, and bearings, as well as the machine shop work it would take to get the broken teeth out of the clutch lever hole and I found a running engine on eBay for just under $300 that I could just drop in. I also started stripping the frame of rust to prep it for paint. my real concern with the whole thing is making a new exhaust. I want it to make power in the middle of the rev range since it will be used around town at speeds under 70mph. I saw this kit online at AJS Motorcycles that is a weld your own deal and I could tack on a megaphone because I just love old Japanese bikes with a megaphone on them.



In my mind no Japanese bike looks complete without them. I also found a little motorcycle salvage yard down the street where I can get a front fender as well as a nice-looking megaphone.

The real problem still remains at getting a title by springtime next year.

I realize you may have been joking there, but a bike is not a car and as much as cars handle better when lowered, bikes don't.

And it's a two stroke so it needs a tuned pipe to work.  With a megaphone I'll be able to hear you from several states away but the bike will be barely able to get out of its own way.

Cool bike BTW.

I'd suggest get a title first and then make a decent tracker or retro MX or retro Motard type bike.  It's a light, fiesty 2 smoke and the world needs more of them running and scaring dogs children and old ladies. :-)

With a megaphone exhaust on a stroker you're just converting fuel into noise without horsepower.

Even if it is just tacked onto the end of a tuned pipe? I understand I can't just have a straight pipe hanging off the exhaust port and expect to make power at all, but there is no way to have a megaphone on a 2-stroke? I do still have the stock exhaust which worked fine I just want that megaphone on there so bad lol.

Anyway I got a lot of the rust knocked off of the frame and I painted it and the swingarm. Next up is to clean off the forks.





Also I want to lower the bike a hair so I can reach the ground comfortably when I come to a stop, I'm a short guy! I'm not looking to put the frame an inch off the ground, just bring it down some so I'm not stretching to reach the ground when I sit on it. I'm just switching out the rear shocks to around a 12" eye-to-eye instead of a 14 1/2" shock.

'fraid not.  You could add a small trumpet to the end of the muffler just to make an obnoxious noise I suppose, but it would sound awful.


I hear you on the seat height.  That's a heck of a difference in shock length though.  Try trimming some foam out of the seat and say 13" or 13.5" shocks.  As long as you can get one set of toes down, you will be OK.  I can't get both feet down flat on a lot of bikes - especially if the seat is wide.
