1972 ts185?s - Horizons Unlimited

**gildomilo** · #1 10 Oct 2006

I believe I just bought a 1972 TS185. Somewhere through it's life the lights and everything was removed from the body. I'm using it mostly as a dirtbike, so that's no worries. What is a concern is the gear box lube. How much oil should be used? Is 20w40 a good choice? Also it seems that the previous owners removed the oil injection system. Maybe I can get a used one somewhere and install that at a later time?

Any suggestions on adjusting the carb?

Finally, the gearbox drain plug is stripped. Can I retap it to a larger size without too much harm? It currently seals, but doesn't tighten up, so I'm not that concerned.

Thanks,
Gil

Hi Gil. I will send you a private message. I am sure we don't need to bore too many people with a lot of TS techie stuff.

I also just picked up a '72 ts185.

I have pretty much the same questions as Gil did. How much oil and what kind do I use for the gear box, also mine has the oil injection system removed as well. Do you know what ratio the gas to oil mixture should be at?

And any advice on carburetor adjustment would be great as well.

Thanks in advance!!

My TS185 is a 1974 and is running 30W oil in the crankcase. To fill to the correct level: take out the small bolt (has a phillips slot) on the forward righthand case. Add oil to the engine. When the oil starts to drain out the forward bolt hole the level is correct. Replace bolt. I pulled my oil injection pump and pre-mix the oil/fuel at 32:1. It runs fine on this but smokes a slightly. Tapping the drain plug hole is very possible. Find a buddy with the tools up and go for it!

The Suzuki TS range, like most Suzuki two-strokes uses their CCI system. Unlike most two-strokes, you CAN'T run premix for any length of time without destroying the left side crank bearings and the big end bearings. These are feed by the oil pump directly, making the Suzuki cranks very strong and with a long life. Serious modification is needed before you can run pre-mix.
