FI bike cutting out

[BikerBoy]

Sounds like you've had water in your tank or in the fuel?

not that i know off,
could that cause the problem?
i recently put some fuel additive in the tank
about a week ago, but ive run a cpl more tanks
of fuel since, i could try and stick some metho in the tank.

just a thought mate. Water in the fuel would give you problems like you're having, but if you've already gone through a few tanks and also used a fuel additive.....safe to rule that one out.
