Hi all. I have a 1998 Fazer which I have owned since 2012. It's a weekend pleasure bike with only 37K on the clock and looked after.

I took her out this weekend, started with no issues and ran as she always does however after about 30 minutes of riding it felt as if she was bogging down and juddering at low speed/revs.

I managed to get home and turned the engine off but when I came back to the bike to restart and move it into the garage it just struggled like nobodies business. It was as if it was fuel starved cranking over, ticking at very low revs before cuttting out quickly.

About 12-18 months ago I had the fuel tank repaired because of a mystery leak that occurred after it had been in a local garage for MOT/service and seals.

Could this be a potential breather pipe issue or does it sound more complicated?

Thanks
