Well I found a little gem, in my mind. It goes by the handle of 1969 Yamaha 100 L5-TA. It is an Enduro, and everything



works, lights, horn, speedo. Kinda unique and in gr8 condition. Has a 2 stroke engine with automatic lubrication done by



not mixing the fuel and gasoline, but rather via oil storage tank which through an oil pump injects oil into the engine



internally. Odometer show 2650 miles, which according to the PO is accurate, as it has been in his possesion for 24 years



and barely ever rode it. Prior to his ownership the Forestry Service had it for checking their towers, it replaced their



horses, barely for it is only 8hp.

$500.00 with $300 of new parts in boxes, so essentially $200 for a 41 year old runner.



A couple of pics HERE and Here. Mine is the burgundy version.

sweet,good luck mate,keep us posted,maybe a photo or two.....i dont think a 2 stroke engine will be held against you

i love those old 2strokes back when every bike was all character

they weren't fast but the looks made up for it

I just got back from putting the carbs that I rebuilt back on my buddy's 76 Suzuki GT 250. He has 3 GT 250's , a 76, 75, and a 73. Thay all run like bears and are more fun to ride than anything. We each take one and smoke up the roads. There is nothing like a 2 stroker!!



Like I told him, I might enjoy riding a brand new top of the line bike, but nothing makes me grin like riding one of his GT's!

I have been reading on other posts on other boards about guys and gals building/rebuilding/mod'ing small c.c. bikes. One guy posted his solo travels from Louisiana to Sturgis in 2009, riding a Honda CT70, complete with a larger tank on the back. He got as far as Nebraska before the engine started to crap out on him. A scooter dealer ended up helping him get a Lifan engine bolted in and back running to get him to Sturgis (he accepted a lift with another group of folks driving back past his home). And then there is the guy who rode a "postie" CT110 out of Australia thru Asia back to his home in England.



So, gotta say that even though they are small, these bikes are still cool to ride and I am always looking for a bargain to put in the garage, fix and ride!

At 6' 3" I find smaller bikes tough to get comfortable on. But man am I jealous. I think that bike sounds pretty cool. Good luck!

One of the amazing things about this bike I have found is, on E-Bay, there are 582 parts listed for sale for it. With



that I have found a couple of links to other sources of parts. I still get amazed daily by the info available online.

BTW when reading the "Users Guide" also found online, this bike uses straight 30 weight oil in the injection tank. I



don't even know if they still sell straight 30 anymore? I suppose 10W-30 would suffice.

Great little bike.I loved my old BSA Bantam 175 cc Two stroke.

You can get two stroke oil from lawn mower suppliers and some larger DIY stores and even Ebay but watch out for silly prices so shop around,

Remember that in a two-stroke engine the crankcase is part of the combustion cycle and pressurised so any leaks from crank case/gaskets will cause problems.

damn the takes me back to my 1969 yamaha ct-1 175 enduro also for the forestry use neat little bike what else was a neat idea is it had two spark plug locations just in case one fouled out you could switch the lead to the other plug and keep going when i first got mine it was a basket case from hell took 3 hours to put it together and ride able top speed around 60 but boy what a great hill climber kinda makes me upset that the person i bought it off of stole it from me.........



i also should of bought another one for 20 bucks.........oh well.......

Shep, thing is, this is not a fuel/oil mix like other 2 smokers, the oil from the oil resevoir tank, is injected directly



into the combustion chamber/cylinder for lubrication. The seperate pump runs off the engine through a reduction gear and



the amount injected is determined by engine speed and throttle position. I am still figuring this all out, but it does not



use the traditional 2 stroke oil, but a heavier 30 weight engine oil. Strange little bike....so far...but interesting



because it does not appear abused and is complete front to back.

That's even better.I'm sure any cheap 30w with the same specs as in the manual would do
