Right lads I’m at a cross roads and have a decision I need help with. The TS185 has a three bearing crank, the outside bearing is on the left hand side and it WAS lubricated directly by the oil pump which also mixed oil with the fuel. My intention was to swap to premix, purely so I never had to worry about the pump failing or mounting a separate oil tank. But if I do that this bearing won’t be lubricated and will seize. I’ve heard of people drilling through the cases beneath the barrel to tap into the gallery that would have lubricated from the pump and allowing fluid in that way.... but is that huckery and unreliable? I’ve had the barrel off to investigate and the piston, ring and bore look mint. Pics to follow. And then, opinions please ;) fletch has been making appearances at shed night and brought something along for show and tell.... a smaller bike, with a bigger engine!

The usual advice for Suzuki auto oil engines is to keep the standard setup in place for the reasons you’ve already mentioned. 

Some people have drilled the cases to get oil flow and I’ve heard of others manually lubricating the bearings with an oil can periodically... both those options seem more annoying than fitting an oil tank.

Spoke to Shaun about this. He has tickled many 185's. 

Has all the port timing for it, and the down low on the bearing lubrication. 

I'll bring it on thursday

I opted not to modify my motor and instead have simply re-installed it with fresh gaskets. I’ll worry about my oil setup once I’ve got her assembled; I’m really starting to fret about the looming Urewera trip and ensuring that she’s ready and reliable. I’d really like to be looking at a shakedown ride in the next couple of weeks, but there’s a lot left to do. Getting all the lights to work and secondering a legit plate will be two major hurdles. Repairing and installing the kick start and shifter will be bigger jobs as well. In the background I have sourced a replacement intake manifold from the local wreckers for $20 (win) and Dad Blackwood machined me a new rear shock pin to reduce the massive swing arm play. I’m also one weld away from having a functional exhaust system. Gotta maintain momentum otherwise I’ll have to ride, ‘gulp’, a normal bike...

So I had a conundrum with the shifter where I could run it back to front and it would work easy but the shift direction would be reversed (race shift) and I HATE race shift, so I opted to engineer a new shifter linkage, sources tie rod ends etc and then Dad Blackwood was like “why don’t you just pinch one from one of the spare bike frames lying around?” So we did, and with little modification, it fit like a glove. Thankyou FXR150 frame haha. Also repaired kick starter and locked in a lot of the wiring, just have to repair fairings and install an Oiler really and we’ll be rolling for Rego! Pics to come

We just cut the factory peg off it’s steel mount, drilled a hole through it and mounted an FXR foot peg equipped with its own shift and linkage which didn’t require any modification, they were even the same internal spline!

Rego day. I took it for my first ride this morning, no helmet, kicked it into gear and the clutch was stuck, sledged across Dads wet driveway with the front wheel locked and the back wheel spinning. It must have looked awesome haha.
