Hey guys.

Ok so I have a 21 that is relatively new, rebuilt about 1000km ago, and its just developed an issue over the last 2 rides.

I'll say first that I made a clerical error the other day and left the fuel tap on and the bike in the sun for a few hours. leading to much frustration from 2 wet plugs (same cylinder). and having to borrow a rather exxy iridium for the trip home (from a mates worked tz250).

Needless to say that since this occurred, the bike initially runs ok, but struggles at the powerband. 2 minutes further down the road and it wont run past 6k. it just bucks and misfires....

First thought was that the floats are now fubar, but turning the fuel off and running makes no difference (running oil injected). I have also tried a new battery. no change....

so. Im now leaving this to the learned masses. any ideas?

the struggling into higher revs makes me think fuel, but the misfiring makes me think electrical.
