I picked up this little TS90 the other day for $300. It was an Offer up sale local to me. To be honest there was more rust on it than the picture seem to indicate but after meeting the seller I thought I would just get it. He was a real nice guy who told me he would sell me his little TS50 when he was ready.

Suprisingly this little bike starts and runs solid with no abnormal engine sounds....ie.... bearings, pins, etc. I used my remote testing/tuning gas tank and it ran nice. It was a little hard idling but the carb just needs a good cleaning. The forks are shot and the rear shocks are frozen in place. It will need things here and there but at this time that is all I'm going to do to it......get it running and reliable and functioning properly. I purchased it with a "bill of sale" only but that doesn't scare me any more. As long as the bike is out of the dmv system (which this one is) I have a guy who can get all the paperwork for it with no hassle.

I bought this with the intention of taking this along with my Yamaha 90 on the RV so me and my wife can use them, etc. Based on some preliminary inspection and browsing ebay I'm assuming I will probably need another $500 to $700 additionally in parts and stuff to get it reliable. So after $1000 in total....plus I'm guessing $150 in dmv fees for a total of around $1200 I will have a reliable little bike that still looks like a rusty pile of crap. And if in the future I decide to do a "kinda" restoration...since there is so much chrome on this bike....it would probably be an additional $1200.....for a grand total of $2400. For now all of this is just math.

The inside of the tank may require a lining but I'll know better after a good cleaning. On the plus side the tank kinda has that iron head "turtle tank" look to it.

I have a shop manual for that bike if you need any info on it.
Thank you for that. Maybe you could give me some carb numbers like jet sizes, how many turns out, etc.

Good to hear that.

The guy has a nice little 50 with appropriate aged patina on it. That little one would be perfect for my wife.

So my next step is to clean out the carb and the entire fuel system...lines, petcock, tank, filter, etc. I can't get into the tank right away but it doesn't look like the nightmare tank off the FZR. Looks like a mixture of some varnish, sludge and rust.....hopefully more of everything else than rust. Even so a liner may be in its future.

My 2nd bike was a TS90 with factory 110 kit it used a half moon rotary valve and was a rocket but never could get it set up right it would eat pistons regularly 15-20 hour was all it was good for. KEEP IT STOCK. keep the oil pump and keep mixing some in the tank too.

Sound advice...

It will remain stock......with the exception of the cat rear tailight....like right out of a 70s J.C. Whitney catalog that my wife wanted. So far counting that and a clean set of shocks and forks I'm around $110 in parts.

Received the shocks from ebay. They were very clean. Installed they look out of place around all that rust.

Took some items off so I could get a good clean with a power washer. Still a lot of rust on stuff though that will never come off. I have a better view of the wiring harness now that the oil/dirt is gone.

I've spent nearly $170 on parts so far.

I really didn't want to paint anything as it would stand way out right next to everything else dirty and rusty but a couple of heavily rusted areas I needed to "rattle can" them. The original filters are non-existent so I used 2 layers of the uni foam.....one oiled and one not.....just like my HT-1.

So things are getting greased up and serviced and cleaned up. Kick start lever was cleaned and greased with new rubber installed..

The biggest modification this bike will see is the cat tail light.

Working on the carb slowly while waiting for the new throttle cable.

Funny how gunked up this carb was it still managed to run fairly well......although it idled erratically.

Wow.......I lost an entire page in this thread. Oh well

Cleaned the carb and installed new lines, cables and replaced the old dug out fasteners with new ones.

I've been trying to look up parts from my usual joints (Chaparral & Bikebandit) but both places have no reference of the model for years 71 & 72. All the little rubber pieces disintegrated when I disassembled the petcock. The only thing that kinda looks similar is the valve from the TS50.......same years.

Contact Sudco They may be able to help you. They might be able to cross reference an equivalent kit, or adapt another petcock.
