Hayabusa engine surge after bike wash or raining

[remmp-it]

Need help here.. I owned a 2005 hayabusa. Usually after i wash my bike or during rainy days my bike engine will haf this surge feeling. Could it be water sip thru the tank? Or water sip thru the plug cap? When its hot weather the bike wil be ok. Anyone had this problem wit their hayabusa?

Check plug caps lor. You already say hot weather no problem means should not be water in tank as it will be affected in any weather if water contamination.

When u lift up ur tank, there's a rubber piece beneath it. Should be that rubber piece nv cover properly. Water seep onto the plug coil when washing or raining. Hayabusa's coil is on the plug itself. I've kena this 2 times already. Bike will be jerky. Like riding horse. I went to bike shop to change to a new rubber mat and solve everything. And dun forget to check the coils, u might need to change that. I've already change my coils 2 times.
