If you've owned a tdm this one should be easy. Wrap the coils and leads in sa tape. If you have COP's then they are likely shorting to the head and need replacing.
i wouldnt be suprised if its just your ht leads shorting outmy old chop was missing a rubber cap and started to run like sh*t in the rain and when i went to play with the plugs i got a bit of a shock.if its fine again tommorow remove each boot and put a smear of silicone around the lead and slide back onto the cap and it will seal it and stop any more water ingress
Sa is self amalgamating tape.Cop is coil on plug
i just lick my fingers and dab the downpipes, spraying water is the safest option thoughi do it quickly and i have asbestos hands (only fairys and millennials use moisturiser lol)
Update! After a bit of drying in the Mediterranean sun, bike now seems to be running as normal again, more than likely it was caused by water around the plugs/cables....
OP said his TDM would also run rough after washing. As someone who has previously owned a TDM I was wondering - how did he tell the difference?Sorry - couldn't resist...
The Fazer is still a bit rough from time to time, will give it new NGK caps and cut 10mm from the leads this weekend and check the drain holes. Might go overboard and do coils+regulator since I'm already messing around with it. Got a pic of it from last weekend as well:
SnipGreat action shot! Bike looks v.nice!
Spiffs bike is going to run lumpy, it's a foccing black one.
