Rode the bike two weekends back and all was good. Was a bit rushed when I got home so bike went straight into the garage without a wash.
Following weekend went to ride and it started ok but only ran for max 2min then died, very unusual. Tried to kick it after that and a couple of times it spluttered but died straight away.

Checked fuel and airfilter, all ok. Didnt check spark.

This week I pulled the carb and cleaned thoroughly. Spark plug looks good, was a little wet. Put it all back together and fired up.
It started second kick but again, only ran for 30secs then died. I tried a few more times and once or twice it turned over but died instantly......so in other words no change from the first time this happened.

I am going to buy a new spark plug to eliminate that but I have had one opinion so far. Before I post that I would like to hear some others, please comment
