I put some NGK iridium plugs into day and it was an instant improvement.
I had the original plugs from new in there and according to the maintenance schedule they are still good till the 48000klm service.
Im currently at 34000klms.
My bike has been stalling 3-4 times when cold for the 1st minute without any thottle ,when its warm its ok.
The bike started up cold ,stalled once and was ok ,so there was an improvement there.
The other area where it has improved ,is when you are coasting at under 2000rpm in low gears.
Before ,it was running slightly uneven and sometimes hesitated when twisting the throttle.
Now the delivery is much smoother.
Its going in for a dyno in the next week or so and Im hoping to get the cold start perfect.
