Hi all,

While waiting for some spare parts, the carbs are finished. So it was time to try and to start the engine.

Finally alive after 2016.  8)

The muffler will be replaced with the marving one, since I cannot find the OEM exhaust for now. This is the one that it came with, and is used just for starting the engine.

Best regards,
Kristijan

Well things are finally coming to an end....

The bike is complete, registered and ridden for a 2000km now.

Here's picture today from Dubrovnik, some 600km away from home.



washed after the trip:



Now it's time to make a first service(oil, filters, lube everything...) and fine tune it.(some jetting problems, some tacho and speedo issues)

Best regards,
Kristijan

Why is the fuel line routed like that?

Slightly overlong pipe needs the heat protecting coil spring on it.

I don't know, it seems like the most logical route?

what would be the correct route?

Ted, you're right, the spring is missing, I'm still searching for it. I need to leave something for the winter service  ;D

I think your route is close but due to to the excess length of the pipe it's a tad higher on the carb top. If you fit the  spring in the future it will reveal the required length.

Yeah, I'll try to get the spring.

Thanks on the input.  ;)
