Look at the diagrams or take one apart, it is very obvious that disconnecting the injection will lead to failure of the bearings.
Copy all. Vtwin was asking about his 'little M31' two-stroke, saying it was strictly pre-mix. If his M31 is supposed to be a CCI system, then by all means, he should be using the pump.

Thanks GP. Really seems like it's just not enough oil to lube bearings in pre mix, but they've been like that for years, so I guess it works.

It's actually more about shielding of the bearings.

Suzuki copied SAAB's oil injection concept for the Sport, Shrike, and Monte Carlo 850 cc engines, all of which have an oil injection system that forces oil directly into the main crank bearings and the cylinder walls. To keep the oil in there from getting too diluted, they also had some extensive stamped metal shielding that covered the main bearings and crankwheels. The upside of all this complexity is that the cranks on these Suzukis are "stuffed", which in laymen's terms means that all the lower end open space is reduced to a minimum and this makes for more efficient transfer scavenging.

Jenna,

I had a TS185, too... my first bike. It was a '71. Then I had a string of Suzuki two-strokes after that. Learned to soup them up quite a bit... they were over-engineered and came with a 12,000 mile warranty, so you could really work on them with a die-grinder. Used to replace the head gasket with tin foil, file 5mm off the piston intake skirt, port and polish the cylinder, put on a Bassani pipe and almost double the horsepower. Of course, that wasn't too hard, since, stock, it only had 11 hp!

Also installed "long travel " shocks from Curnutt, in California, and put preload spacers and heavier oil in the front forks. Geared way down, it was a pretty good mountain climber.

Later, my father got one, and we souped it up some as well. Wish I still had one.

Enjoy!

Jenna, we added a 2nd Bultaco to our house hold. When are we starting a gang and tearing up urban trails?

Jenna, glad you fixed all your issues. I am going through all this with my two little Suzuki smokers. Takes for ever to start my little K11p and my M31 only really started and ran once since Jan 1st.

Hi, a month since the last post but I'll give it a go.
I recently bought a TS250 1981. Runs great but I have a leak coming from where the neutral switch cover should be. I am going to get a cover for it but I was wondering should it leak with no cover? The seal is strange as it has a metal ring around the shaft and then rubber. The cover that I will get has an o ring so is it this that is supposed to seal it?

I have attached a pic of the shaft and seal.

Thanks very much for any help.

John

Yes the covers had o-rings that sealed them, they will leak with no cover or if it gets cracked.

I know I suck. Just drug a SL350 home and a R90 S, so I've got my hands full. I will be getting back to the TS soon, I promise.
