Problem with TS185

[Travsta]

Hello all,

I am a new member but have been reading your posts on this site about TS185s and they have been extremely helpful. I recently obtained a TS185 for $450AU and it runs a little rough so i'm trying to fix it up. I dont know a great deal about bikes so bare with me but i have been doing a lot of reading and have found out that these bikes are pretty tough!

Anyways, the bike runs OK after it starts however this takes a little bit of work. I thought it may have been the carby so i pulled that apart over the weekend and gave it a good clean with some carb cleaner but that didn't seem to make any difference. It seems to be a problem with the spark plug. I replaced it with a new one and it kicked over fine and i rode around on it for half the day but when i went to kick it over again the next day it wouldn't kick. After pulling the spark plug out it was black and covered in what looked like oil? I tried cleaning it but it didn't help. So i chucked a brand new spark plug in and it kicked over perfectly again? Does anyone have any suggestions of what it may be?

Also the bike is really really loud. It seems there is an exhaust leak at the front of the bike (i can feel air coming out of the motor when i place my hand near the front tyre). Is there some type of seal that connects the exhaust to the motor that i have to replace?

Any help you could give me would be greatly appreciated...

Thanks
Travis

Great bikes, I worked on a ton of them but they are no longer sold in the USA. Check one of the online parts books and see if you are missing any seals where the exhaust goes into the cylinder. The US bikes had a tricky little seal and as the bike wears it will blow out and make lots of noise. If you can find any of the bits put them in with a layer of high temp silicone and see if that helps. The bike will use plugs occasionaly but while you have the carb apart see what number is on the main jet and idle jet. They are the two removeable jets you see when you take the carb float bowl off. Check with local shops to see what is a proper size. Clean and oil your air filter to see if it is clogged. Also check your transmission oil level to see if you have the propper amount. Sometimes a oil seal will go out and you can suck trans oil into the engine causing plug fouling. Run a good grade of injector 2 stroke oil in the injector tank and go have fun.

Hi Trasta,
I don't know about your TS and you certainly should get the right manual, but you might like to take a look at this thread:-

'cos you say that you don't know much about bikes generally - I found it very useful for general advice; I wish I had had some of that advice before I started some jobs!!

BTW.

Cheers,

Thanks heaps for your replies.

I have managed to dig up some new seals that are located in between the exhaust and the motor so ill put them in over the weekend and see if it makes any difference. I'm assuming it should give me some more power as well...

Ive already put the carby back together but it was pretty easy to pull apart so i may check the jets to see what number they are over the weekend as well. Does anyone know off hand what they should be?

Thanks again for your help!

Good progress then! Go careful with the studs for the exhaust - you would not be the first to strip a thread or snap off one or more studs (more posts in here about how to deal with it when it happens!).

I suggest you do a search in here for workshop manuals - there may be one available electronically for your bike; even if there isn't one here, you may find one on the WWW.

Hi I live in Mexico where the TS185 is still available new. I bought one last year and have been happy with it. The main jet on the carb should be a 195. This only controls the mixture at full throttle though. Between the one quarter and three quarters open positions on the throttle the mixture is controlled by the needle jet. You can adjust this by removing it (just take the top of the carb off and pull out the barrel) and moving the clip on the top of the needle up (weaker mixture) or down (richer). At idle (closed throttle) the mixture is controlled by the air screw on the right hand side of the carb. Anticlockwise (weaker) clockwise (richer), but don't take it out more than three full turns . Here I live at an altitude of 500m the bike was running a bit rich at 4000 rpm so I moved the clip on the needle jet up one notch and now it is much better. I have big problems with this bike when I go up in the mountains here. Anything above 1000 mts (some are 2000 ) and it runs really rich and lacks power. Pretty nasty if you are off road on a steep incline I can tell you. I think it really needs a slightly smaller jet even at this altitude as I think it is running rich at full throttle. Haynes produce a workshop manual for this bike which is very detailed and parts are still produced. Good luck
