Yamaha LS100

[malber]

I took a ride down Rt 28 yesterday after work. My planned destination (or excuse for the ride, take your pick) was to go to the Apple store in Salem to look at the new iPod nano and the iPhone. As I was riding down I passed a guy tooling around a parking lot on what I took to be a '70s Honda. So I took a couple of u-turns and pulled into the lot. Badge on the side of the bike's tank said "Yamaha." I was surprised and talked to the guy a bit. Turns out it was a 1972 LS100 two cylinder two-stroke. He's been working on it for the past 29 years. It only had 700 miles on it! When he got it it only had 500. It wasn't totally pristine and he went over a lot of what he had done to bring it back to working order. It was cool to see the XS1100's great-grandfather bike. But I'm bummed that I left my camera behind. Anyone else know much about this bike? I couldn't find anything on google.

I got lots of google hits, looks like there's a few parts available out there too. That one looks a lot like the little 200 SWMBO had as her first ride. Fun little bike, but certainly not something you'd want to go a great distance on.

They were called the twin jet. My buddy had one he and rode his when it worked and mine when mine was workin. I had a jawa 250 then. They both had a top speed of about 65 MPH. Sure brings back lots of memories. There is a guy out west trying to sell one on another forum that I frequent. At least I think it's another forum sometimes I do get mixed up, must be an age thing.

Spitten image of the one I had. Fun bike when your 17 and only push the scales at 150lbs. Was my first "real bike", a giant step up from my Suzuki 100. Actually put a set of "chambers" on it for a while, way to loud and moved the powerband to somewhere between 7200 and 7500 so I put the OEM stuff back on. Actually rode it from Albuquerque to Denver and back, big mistake but made it with no problems.

Wow! Talk about going down memory lane. My first bike was the YL1 vintage 1966. This was the younger sibling to the LS100. Great little bike and it felt a lot stronger than 9.5 hp.

My first bike was an RD125, 125cc twin two stroke, 74mph top end (going down hill). Awesome little bike, didn't know much about bikes back then but remember, changing-cleaning plugs every ride.

Had one of those Twin Jet 100s. It was my first real motorcycle. Bought it from a guy for $60. The jugs were off of it as he was doing a bore job and broke off the 2 center cylinder hold down studs. Buddies dad was a machinist and made me 2 of the proper length studs with 1/4-20 threads and Helacoiled the block for me. Man that was a fun machine to ride. Ended up selling it to a guy who needed a motor for his 125.
