I took may bike out last week for a little ride. On the way home it started to rain quite heavy. When i got round the corner from home the bike seemed to lose power and sound a very deep/dull sound! The revs were dropping and it cut out a few times.
I got it home and assumed it was the rain as i have no fender extender (i read about a common problem on here). I put the bike in the garden and covered in the view to having a look some time this week.
Anyway i got it out yesterday and it is still the same, if it was the rain then this would have dried out by now so i am now worried.
Does anyone have any idea ?
