I have used a couple of there ring sets, also there inlet rubbers. Good gear and the Gurls blouse guys like them. There oversize piston and ring sets are good prices if your bores are worn.

cruzinimage.net there in Japan but cost and postage is good.

About 7/8 out from lightly all way in, carefully as they snap the point off. A colortune is very helpfull to get idle mix right.

I would agree with the vacuum pipe from carb 3 to fuel tap also. Block that pipe and turn tap to prime to see if it runs on 4 cylinders. Don't leave tap on prime without engine running. Check the tap works as it should and shuts off with engine off.

I had a similar issue, when I removed the switch the brass disc was broken. Fitted a different one and all good. I do have a low pressure guage that connects to the oil gallery on right bottom of cylinders.

I have one of those systems on my GS1000, been on 2 years and no issues. I got mine from Aliexpress.

That's the salty monk conversion. Same calipers I have on my gs1000, but with bracket on inside of fork.

Yes brackets made by myself. Adapter with Kwak caliper carrier.

I also fitted another set with SV650 calipers on my GS850.

Fireblade discs and Kwak calipers can be made to fit.
