Hi Stu,

I'm wondering if you could have disturbed the ignition sensor on the LHS front of the bike?

Failing that, try undoing the changes you made, new components can be faulty from new, perhaps change one item at a time.

Good luck

Did you gap the plugs correctly? The gap needs to be bigger than standard plugs! You may not be getting a good enough spark.

Gap for iridium plugs should be 0.9mm, compared to 0.6mm for standard.

HTH!
