ok so i didn't make it to the hills today, i rode to my brothers to pick him up turned the bike off and had a coffe, when i went to start the bike it only fired on 3 cyclinders. i thought shit ive created the same problem as glen with his zrx hahaha anyway i pulled it apart to check the plugs and it looks like number 1 has failed as it was looking all shit while the rest have burnt clean, i hadn't touched the carbs so it must be a dead plug.
went and got 4 new plugs and it fired on 4 straight away, went for a ride around the suberbs and then let it cool off to see if it was going to do it again and it didn't i repeated the suberb run a few times just to make sure as i wasn't in the mood to get stuck in the hills and so far all is good. just went up to kersbrook and back and will see if it goes sweet in the morning.
on a good note i got to check how the plugs were burning after the exhaust install and they look good an it's not leaning out at all.
seems to have a tone more torque as it just spins the wheel at will, an power wheelies are no probs,

i still want to get it dyno tuned so i can run the k&n filter aswell.
if these plugs hold up then this is the best mod i have done to it so far.
