TS185 questions

[SMOKEU]

I have just bought a 1970s TS185. It still has the factory oil injection system which is something I want to get rid of ASAP. There's a bottle just by the seat which contains 2 stroke oil, and then a hose connecting that bottle to the crank case. If I want to get rid of the oil injection, then is the simplest way to do it to just empty out all the oil from the container and then run it on pre mix? What fuelil ratio do I use? I was thinking I could disconnect the whole system, but then there would be a hole in the crank case where the oil feed hose goes so I will need to plug that.

Also, what gearbox oil should I use?

I have noticed that the bike also has 2 spark plugs, only 1 of which has a lead connected to it. Is this normal?

I have an old TF185 here that gets used as a hack,I just cut the hose and plugged it up and removed the bottle, Yep normal to have 2 spark plugs, I run mine at around 25/1 and it,s been going like that for years. Think I have clutch saver oil in it too, cant remember the brand though.

How well sealed does that hose have to be? I was thinking I could just cut it half way then double it over and tie it with a piece of wire or something.

I just cut it and shoved a bolt up it with a hose clip round it.What about the cable from the throttle to the pump/ or does your bike not have one?

From the hand throttle, there is a single cable. The cable then splits into 2 cables, 1 of which goes to the carby to control the throttle, the other enters the crank case directly next to where the oil feed goes.

Also, how do I check the gearbox oil level? I can see the filler cap but there's no dipstick or sight glass that I can see.

Maybe the dipstick has been broken off of your filler bung at some stage, As for the cable, I just put a cable from the throttle to the carby and did away with the one to the pump. It should have the oil capacity stamped on the casing somewhere.

Why the hell would you want to get rid of the oil injection

Apparently oil injection is prone to failure on old engines (this bike I have is in a rough condition and looks like it hasn't been maintained well) so I was thinking of running it on pre mix just to be safe so I KNOW that the engine is being properly lubed.

You know when the oil has stopped flowing ... no blue smoke.

You can remove the the suzuki CCI oil injection.... BUT
You HAVE to pull the motor apart to do it and drill a hole
in the left cank case at the bottom of the transfur port
channel .. the hole has to go though to the left mail berring.

If you take a look at the oil feed line to the motor you will see it
feeds in to the crank case though a banjo bolt.. then directly to the main berring
Then after the berring the over flow the mixes with the air in the crank case
to lube the big end & bore....( right main is lubed by the gear box oil)

Yamaha etc feed the oil directly to the intake port so just pre mix the fuel
and yer good to go.... But it don't work like that with suzuki...
You can just remove the pump on a suzuki & pre mix it.. it won't seize
but the left mains going to go in quick time...

OK I'll just leave the oil injection system in and use that, then I'll periodically check for blue smoke and a decrease in the oil level.

Now, for the gearbox. I had a look at the gearbox filler and it doesn't look like there ever was a dipstick under the gearbox oil filler cap. I can't see any obvious signs that it has broken off. Now 2 stroke bike gearboxes don't work on the same principle as car gearboxes where you just fill it right to the top, do they?

Just do a google search for the amount of oil it takes...
drain it / re fill...

It's leaking gearbox oil as there was a lot of oil build up around the bottom left of the engine. It's often quite hard to get the bike into 1st gear but the rest of the gears are fine and the bike rides well. I'll do a gearbox oil change ASAP before I even ride it again. I just downloaded a workshop manual for it so I'll have a look.

Can't complain too much since I only paid $340 for it. It'll make a good summer project to keep me out of trouble.

Below the gearbox filler cap you will see a 10mm head bolt with a phillips/cross head screw slot on it. Stand the bike upright and fill until the oil comes out this hole. A dead simple and foolproof method.
