Issues with TS 185

Hey guys,

I picked up a 72 Ts185 a few months ago and have been trying to get it into the best shape I can for a epic ride from Milwaukee to South America in January.
So far I have done a lot of work and thought I had it running good until a few days ago.

I took it on my first longer ride and it seemed to do great for an hour but after I stoppped, I coulden't get it to run. It would start and rev high then die and not work for an hour and then do the same thing. I had good spark, fuel and compression so I figured it was my carb.

I cleaned out the carb and it started right up, but would not run without the choke. I rode 10 min home with the choke on and the bike would die if i let off the throttle. Once home I tried playing the the fuel mixture and idle screws but it did not help and now the bike will not start again.

Other possible issues are:
That the copper ring between the engine and exhast is fried and leaking. Trying to track down a replacement.
The previous owner replaced the stock air filter with a cone one.

I would love some guidance and ideas!

DUDE. This is brilliant.

Well done in so far as you have the gumption to ride that bike to South America. I had one of those for a brief 6 months last year. I rode the hell out of it and sold it for the $500 I paid for it. I still have a '72 TC90 and TS400.

First off, that exhaust leak that you mentioned could very well be the stem of your problems. I had issues with my bike as well that seemed to clear up after replacing that copper seal, along with a good carb clean and fuel change. You may also have a crank seal leak, that could cause you some issues as well.

I'll leave the rest of the mechanical talk to the 2 stroke gurus out there.

Either way, I hope you enjoy getting 30 miles to the gallon on that beast. I remember hitting 72 mph on mine before I felt like I was killing it. If you can find an old TC185, you'd have a 5spd dual range transmission with an effective 10 gears. Good luck finding one of those however, as they are nearly impossible to locate.

Keep us updated on your adventures. I trust that you plan to carry a replacement of all of the major seals and gaskets for the bike? You'll need one of them eventually!

Thumbs up

As he posted also on the TS/TM/TC forum (Suzuki TS TC TM Forum • Portal ) I have replied over there. This forum started as there were so many posts here for advice on these great old bikes, and I have the privilege to be the Admin there.

However, any words of advice here will also be helpful to others reading this post, so feel free to post.

Cheers bloke
