1974 ts185. Runs well. Carb is slowly leaking red fluid when bike is off. Crank case appears to be leaking oil when not running. Also owner i bought it from was completely bypassing the oil injection system. Left a cut cable cap on the oil pump and just added premix to run the bike. Supposedly the oil pump works but i do not know how to test this. Will bypassing this system damage my engine? Any thoughts on the leaks?
Thanks Ryan.

I think they have the suzuki cci oil system
running premix doesn't cut it as oil is feed to bottom end and top .

Best best way to test ya oil pump is to take it off and use a drill to spin it and see if oil is pumping
I have just been thru this as my oil pump failed due to a blockage and ceased engine.
in my case i completely disassembled the pump and washed it out with kerosene.
I found some silicone like substance which i guess was water mixed with oil ?? .

Also note to test your oil lines are not blocked

Also note there is a purge bolt at bottom of pump to purge air from the system

Also note that the amount of oil is more from the top end out let than the bottom

See below link for oil pump test its for a jet ski but the idea is the same .
The link

See below link to service manual

Hi Ryan, welcome to VJMOG. There's been quite a few discussions here about the TS185 and a couple threads about the oil system specifically. If you look in the "Suzuki" section, I'm sure that you'll find some helpful information. Here's one that may help you http://vjmog.com/ftopic-11812-days0-orderasc-0.html and another on how I verified the pump operation http://vjmog.com/ftopic-11029-days0-orderasc-105.html . Keep us posted on your progress.

......Paul

Short answers:

You cannot run premix alone in Suzuki with CCI. Unless modifications are mare to the crankshaft, the bottom end will not be oiled.

Never blow compressed air through the oil lines. It will damage the check valves in the lines.

Red fluid leaking from carb when engine off? Gasoline and two much red two stroke oil or too much fuel fuel stabilizer?...... Idunno

Thanks for all the help guys. I have so far gotten the oil injection pump and lines off. The lines appear to be intact and the mechanics of the pump seem to be inact as well. How would you guys suggest i clean the oil injection lines if compressed air is not an option? Is there anything i should clean the oil injection pump with since i have it off. Also do you guys know or prefer any two stroke engine oil? Is there a preferred brand?

The good news is that the inside of the lines are likely very clean (unlike what the outside of the lines may look like), for they were filled with oil and sealed at both ends (check valve at the engine side, pump at the other). So other than purging the decade(s) old oil out of them, they shouldn't need additional cleaning.

The feed line (tank to pump) does not have a check valve. So you will want to drain that, and the tank, and clean. Your favorite solvent and air dry is sufficient for that task.

What I have done in the past (on a T500, for reference) is to remove the pump, connect the lines to the tank and the pump (with the engine connections removed), and drive the pump with a drill. Check for proper rotation. Set the pump arm for full throttle (more oil flow). This should push oil through the lines.

Sometimes oil wishes to only go through one end (cylinder end) and not the other (bottom end). I've then capped off the end that is flowing, using an appropriate sized bolt/nut, to get oil flowing out the other. It moves a really small amount of oit, so takes a little time.

As for oil, any 2-stroke oil which says it is for injection is OK. One trick is that you can switch from BelRay oil (which is blue) to Silkolene (red). You can then see the oil moving through the lines once everything is reassembled.

What Conner said. Here's a little more, ........ You can use an oil squirt gun can to flush out the lines. http://www.vjmog.com/ftopict-4171-squirt.html

Also, you can enter keyword CCI into the VJMOG search engine for more info.

my lack of knowledge on cci oil pump system is why I came to this forum in the first place
I pulled the pump to bits and flashed everything with kerosene thats when i found the snoot like substance which caused my blockage.

I used a straw from a kitchen spray and wipe bottle to blow air with my mouth from the carb end and some of the snoot came out the banjo end to.

if you got your line off I cant see why you cant run a bit of kero down them to clean them
I would note the check valve thing the others talk about
Makes me wonder if I should have been able to blow air through in the direction i did on my 73 suzuki a50ll?.
rebuilt top end yesterday and running in all seems normal
