When changing the exhaust, I reckon I should re-jet the bike, what have you others done?

Any systems that are preferred value/output wise.

Or maybe someone who has a complete front half of the std. system? :)

Hi, i've just fitted a cut standard system with a dual port blue flame can and left everything else standard exept for the hrc fuel tap mod and it goes quite well, no flat spots at all! :D

Did you check the plugs?

Yeah i changed the plugs at the same time, why?

My questions was ment like this, have you checked the plugs after fitting the exhaust to check that it is not too lean or rich?

No, it rides fine so i think they will be o.k, but now you've said it i might go out and have a look at one.

Are fouled plugs the only way you can find out if it's running to lean?

when i got my first nc30 it had a standard system cut with a jap home market can,standard jetting,it ran great,got it up jetted to 120/122 and it pulled better from light etc but when i finally got it dynoed the operater said it was very very rich,and put it back to standard....again it ran brilliant if a little weak pulling away from lights...

just whatever you can get,i have seen and heard of jap aftermarket systems like ethos,tsr,beet,yamamoto going for in and around 150 but i have also seen the flip side and seen systems go for £500+,i still think so lovely sounds and performance can be got from just a standard system cut with a can,but the jap ones are usually lighter and give better powers,but weigh up are you going to notice 2bhp and be happy spending an extra £150 to get it ?

good call,take off the standard uncut system and buy one thats already cut and bop a can on there,happy days....the cut system you buy you could always replace the rusty old coolars for some s/s ones so they never rot away again
