Fixed. The mass cable from the cdi was chafed by the frame. Found it with measuring and wiggle. All good now.

Cleaned the carb again today. Checked also float height measured 6 with the tube and 25,5 on the bowl. Still running shit. Pulled the sparkplug and that’s a bit black, seems a bit rich. Played a bit with the pilot screw 3 turn out now and running much better.

Didn’t went out for a run, but could ...

Here’s a video. At the end it happens.

The carb is overhauled by Motoritz and went perfect for the first 200km. However I checked the float level and the choke. There’s is a fixed choke installed and that also was ok for 200km. Could it be the advanced system which is behind the lh case? Or a loose nut on the rh side?

Hi guys,

It seems I’m having some issues with my stock 1vj.

The engine had some maintenance, new piston, headbolt repair due to the std issues and the head is overhauld. Anyway it ran fine for about 200km and suddenly at a nice afternoon start it starts to splutter. I’ve checked everything, well ...

I had the same. After polishing the screw, tightened even more, checked it all. Finally there was a small hair crack inside the float chamber were the screw enters, so it kept poring out. Probably over tightened several times….

Wilbers is as best as Ohlins mate.

Found the leak….headgasket

So I’m able to source a 34K03 cilinder, which is improved, more cooling fins and deeper threads. Before I buy, can anyone confirm it will fit the 1vj cranks and the 1VJ head?

Cheers

Picture?

Found the oil leak….gearbox is broken in half, don’t now how….

Exhaust is still leaking with new studs and new gasket, damn bike.
