I did do some preliminary fitting of the radiator. I still like the idea of the radiator being "stealth" but sadly it's not going to happen. No matter how I move it around it still hits the top of the triple tree(when turning) and the lower plastics would also need to be heavily modified.







With the radiator that low, I could use the injection oil tank as the coolant reservoir. A win win.

I still have my original option to locate it over the front fairing.

I picked up some threaded rod couplers(fancy name for really long nuts)



I swapped them out from the "spike" nuts which actually came in handy when transferring the hole locations to the mount template .











The template is a tad oversize. I just wanted rough idea how hideous its going to look.

[ryan_ott]

If you paint it to match it shouldn’t look too bad. Well it’s the price you pay for speed.

I finished the cardboard template for the radiator mount. It isn't pretty, but I think it will be functional.







Radiator/reservoir installed and plumbed.














I didn't have much of a choice for the reservoir location, but think will work out. Had to fab up some copper fittings, getting a hose to bend that close was impossible.



I came up with a way to seal the connections.I did this on both fittings. Pressure tested to 5 psi without leaks.(played safe, did not want to blow up radiator)

plastic tubing/o-ring/plastic tubing/o-ring



And the location clears the re-installed turn signals. I didn't want to do away with the front fairing turn signals, but I don't want to cut up good plastics until I am satisfied with how well the engine runs.





I am also toying with the idea of adding a auxiliary cooling fan. I have this one from an old PC power supply.



And it's also lit, but think the po po will take issue with it being blue. The nice part, it only draws .3 Ma. Still looking for a larger version, and will be mounting it between the radiator and mount.




My next snags, the water pump & plumbing out of the cylinder head.

The water pump drive nut/pulley is the wrong pitch thread. My try to rethread it if its not hardened. Also need to fabricate a bracket for the pump too. Also toying with the idea of going with a electrical water pump instead.



The clearance between the seat tub and the coolant fitting on the head is close. Thinking of brazing a 90° copper fitting off the top and doing some plumbing so the coolant hose matches the same angle as the cylinder.

lol that shinny cooling fan looks awesome!

But wouldn't it make more sense to mount the fan on the back side of the radiator and draw air in through the radiator and through the fan and blow it out behind? Imagine blue light shinning behind the radiator!

I also wanted to have a more stealthy approach on the radiator but I also couldn't find a good spot so I was either going with a front position as yours or leg space area. Ended up sacrificing some of the leg space.

Yeah man that looks great. Everything neatly tucked away behind the front fairing is nice, but that big in your face radiator just shouts this thing has some power!

[90GTVert]

Neat setup. I like how reversible it is. I've got panels cut out and stuff like that and yours looks like if you wanted to go back to AC there'd be hardly a trace that it was ever LC. Nice work.

I mentioned in previous post that I would install the fan between the radiator and the mount(behind radiator). I just showed if in front for the "bling" factor. lol

Thanks.

Not sure where I am at power wise, but it does looks like its ready for the drag strip. I hope it doesn't draw to much "unwanted" attention.

Thats my plan. If it doesn't work out, I can always swap back to the polini corsa cyl and go back to the previous cosmedic look. Plus I really hate modding perfectly good plastics.

This is a peugeot cylinder on a kymco engine. Port timings are not ideal but do-able. It might not be a working setup. It starts, idles, revs up some, but wot it runs like crap. Then again I use a lot of 2t oil @ assemble and running it the basement does not score too may points with the wife. I want to get the cooling buttoned up while still in the basement, its cooler working there.

[gsx600racer]

I am a little closer with the cooling system. I got return from the cylinder to the radiator figured out.







I found a brass faucet adapter that matched the thread in the cylinder head. The hole thru it was a tad too small for a 1/2 copper elbow to fit in. The "street" version was too small. So I took the cutting wheel out of the tubing cutter and kept rolling the elbow end down till it fit into the faucet adapter. I lucked out.

This isn't pretty, but I think it will be functional. I wanted to aim it down more, but it would hit the head when I spun it on and off.

[gsx600racer]

I had a chance to "PRE" fit the water pump and hose routing. I am trying to come up with a bracket option that looks decent. I just wanted to see what it looked like installed.





I also picked up a plan "b" option. (Prius inverter cooler water pump)

[tsimi]

I use the same Prius pump on my LC build.
Man I'd love to get that plug you got on there. Mine didn't had one.

[oldgeek]

Looking good there man! I like the looks of the mech pump myself.

[ryan_ott]

Looks to be coming along nicely. Nice job
