Does the 550 share the same coils as the 400&750? Only asking as the 550 has developed a massive flat spot right up to 3500rpm and was hunting at tick over today when ridding in the rain.I have a spare set of pattern coils I could try so it would be rude not to try them.
On mine the rain was getting in between the HT leads and the coil. Tried sealing them but it didn't last
