Here is the update. The fuel line was already very tight and it was chocking... probably happened when i installed the jack up kit and it moved a bit.

Also for anyone not from the UK interested in a jack up kit for our model i installed a V strom DL650 one. It was plug and play!

Could be a blocked tank breather. Open the fuel cap and try again. You will need two keys as you cannot remove the key while the cap is open. Is the pump clicking when you turn on the ignition or when the problem occurs?

Sadly the bike is already in the machanic so i cant do much. Your idea seems reasonable. Maybe the breather got stuck or so when i rise the bike.. The fuel pump clicks every time so i am sure it works.

I am asking for ideas so that i will be ready when he calls me back in case he tells me something extreme..

Hello, i have been silently reading many posts this past year since i bought my FZS600 and this forum really helped me a lot.
So i will try to describe my problem. I transformed an old but in good condition bike to a cafe racer. The bike had 40k KM on the clocks. I changed oil, sparkplugs etc. Did a complete service. The bike was working perfectly before and after the service, i even put some fuel cleaner suggested in this forum to clean the carbs even though they didnt have any problem. Then i synced the carbs myself.

I did 700KM since then without any problems. I only ride at weekends.


1 week ago i intalled some "dog bones" to make the bike higher up by 40mm. It transformed the bike riding wise. I did a quick 5 minute run around the block and was so happy. I am not sure if that did something to the bike but since then it all started.


Then at  night i decided to do a ride and after 1 km of riding my bike turned off at a traffic light. This never happened before... I quickly pressed the starter and it fired up ok. Then after 50 meter when i opened the throttle the bike was misbehaving. Like it was out of fuel or something even though it had half tank inside. I thought it will pass and after another 100 meter the bike cut off. like i turned the ignition off. Pressed the starter 20 times and the bike was not turning on. Waited 20 minutes trying to see if something was moved and i tried again.

The bike turned on ok and the throttle was responsive. Then after 100m it cut off again. And was not starting..
After many many attempts when it started i had to open full throttle with first gear and the bike was running at 10km like it only used 1 cylinder.. and when it reached 6k rpm it all cylinder fired up like crazy and then when i had to brake it turned off again.. and i had to do this 100 times until i got back home.

I visited a mechanic today but i m asking here if some of you have any ideas so i wont be ripped off.


Thanks and sorry for the long post.
