Low buck outlaw

Merry Christmas and be unsafe out there.

I’m now trying to hoard as much tecumseh 3hp-3.5hp stuff as I can. I’m waiting on a guy to let me know if he has any spare h30’s..

You see the shocks on the back of the free blue mini bike I posted about? Same shocks same made in Italy stamps and markings everything. I was able to pull the busted shock off the outlaw and replace it with the same exact shock absorber. You would never have known that shock was replaced if I didn’t say something.View attachment 130846

Hay, that blue one looks like my sears drover, even same colour

It’s probably a drover

Don’t peel off that sticker.. noted.

Makes it even better this is a low production straight bar ‘70

 

[Thepartsguy]

Down the rabbit hole 16 different models of mini bikes available from Michrina enterprises in 1969 and no mention of model changes for 1970. So 9,261 divided by 16 says there is about 578 of each individual model sold in 1970. Heck even if they only focused on 10 models in 1970 that would still be extremely low production numbers.

Thanks for the history lesson! There is a guy in the Gokart section that needs your help.

The h30 tecumseh on my chopper was built June 8, 1970.

That chopper frame is the absolute '70's bomb! I love that look, even though powerslides in that 3" of snow would be out of the question for me with my long legs, betting you have fun with doing that, the short footpegs allow for it. Here's a link with some minibike seats (12" and 19") that might interest you, keep you in the saddle better when it gets loose.............

Question: Does that motor mount with the rigid jackshaft attached have double sliders for adjusting both chains independently? That would be soooo helpful, and something I never see on gokarts. Never thought about it on minibikes.

The jack shaft is on it’s own plate. So both chains can be adjusted individually. You use the bolt through the jackshaft plate to push the engine away from the jackshaft setting the engine side chain tension. Then you slide the whole shebang engine/jackshaft and all forward setting the jackshaft to tire tension. First time I have seen anything like it either.

Awesome! I'm going to apply some brain thought to how that can be built into some of the gokarts seen on this forum. Where's my Tylenol?

I just found this picture on the oldminibikes forum. This is the jackshaft plate on my chopper. The engine plate welded to the bike itself also has sliders. If you could re-create these I’m sure people would want them for there Indian mini bikes specifically.

 

[madprofessor]

What in the world is that spike sticking out forward from the vertical plate all about? I can see it on the left side shot of your chopper also, but can't tell what I'm looking at.

 

[Denny]

That is the adjuster bolt. I can’t remember who, but that plate is still made.

That isn’t a spike it’s a long bolt and the plate is threaded. You tighten the bolt to push the engine away from the jackshaft to tighten the first chain. Then you slide the engine and jackshaft setup forward to tighten the second chain. The long bolt buts up against the oil drain bolt I’m guessing to keep everything tensioned. There is a nut that locks the bolt to the plate so it never unthreads away from the drain plug. If I wanted to I could take the jackshaft plate off turn the rear wheel around and just run a chain straight off the clutch to the wheel sprocket. I would still have the sliders on the engine mount.

Found these pictures on the internet they are not mine. But here is another ‘70 straight bar someone found in Michigan. The original Michrina enterprises tecumseh is gone and a second sprocket added so the brake stayed functional. Of course that means the jackshaft is gone.

 

[Denny]

I like your jackshaft set up better. But that bike is cleaner. Either way they are cool!

 

[madprofessor]

a second sprocket added so the brake stayed functional.

Are you saying a second sprocket is being used as a brake disc there? My current disc was $32, but that's not much more than a sprocket, geez.
Figured it for a scrub brake that was very common back then. Oh well, they did wear tires out, and any other type doesn't.

The factory brake used the factory tire sprocket as a disk brake. They removed the jackshaft so the chain would run to the tire sprocket directly off the clutch from the 5hp. they wanted to keep the brake so instead of removing the brake and flipping the rim they just added a sprocket to the other side of the tire.
