spark plugs

NGK are as good as anything and better than most. Does your bike still have the Air Injection system still in place? If you remove the tank (unnecessary for plugs alone) you could remove the AI system at the same time.

 

To put it simply, you need to remove all the plumbing and tell the ECU that your bike no longer has AI. To do the latter download a free program called TuneECU and purchase an OBD (OnBoard Diagnostic) cable. I got mine from here:

Hang on there matey, are we still talking about the AI system? Sounds like you could be referring to the O² sensors in the exhaust manifolds ?

 

I would stick to NGK or Bosch, both have been good for me on all sorts of bikes

Hi and welcome - stick with NGK plugs they work fine.

 

yup TTP tunes require the o2 sensors to be removed, these are attached to the exhaust down pipes not the cylinder head, just saying as there seems to be a bit od confusion.
