newbie with nc30 issues

You mentioned full throttle and only goes to 1000rpm.

Have you had it over this at any point, and if so.. how did you get it there?
If it's by adjusting the choke for example, could it maybe be a stuck throttle cable / linkage?

I'm also a bit of a newbie... so not sure if this helps much...

thanks for reply
no the throttle is fine moves freely
guy i bought bike from has a complete bike that he is giving to me so i can swap bits over he said i can have it as long as he has bits like forks wheels swingarm race exhaust to sell on

does anyone think it could be pick ups ????

Hiya, have you turned the tickover up? 1000 sounds very low. You may find that when its up at about 1400 its a lot better.

[mikevo]

have adjusted idle up now at 1200 ish still no difference

so when you open the throttle does the engine bog down and die as though its trying to pick up and get going? or does it just stay as it is at1200rpm with no change at all.

If its the first then its down to the carbs and fuel system.
Check the simple things first, are the carbs drawing fuel okay, check the vacuum pipe is operating correctly and has no kinks, next that the fuel line has nothing in it and the diaphragm on the petcock is operating with no splits. You could drop the whole fuel tap out to check the tubing hasnt been blocked by crap in the tank.

If okay move inwards, check the air filter is not clogged up and the box is seated on the carb rubbers correctly to keep pressure up.

If all okay move down to the carbs, first check the cables in case the choke mechanism is holding the slides open this causing slight hesitation on pickup.
If all good then i'm afraid off with the carbs, check the float chambers are clean and the floats are moving freely, as your there check the needles and jets are clear(and a good size for your setup) and the slides are moving freely.

If not this then as you've started on the electrical just move from the obvious (plugs and lead) outwards, it could be worth checking the reg/rec as the joints and conections on these can rot and leave you a lose wire there.

Possible it could be the coils but unlike them to go at the same time unless there is a grounding fault somehwhere.

Good luck and at the end of the day your getting to check the bike over very well

[mikevo]

carbs were cleaned by me and also more fully cleaned by a bike mec ,couldnt fix it
new plugs tried other coils i have etc
been given the other bike which cant get running (if i could get that to run i can theink about swapping things over

[Cammo]

Mate your best bet would probably be to take it to someone who knows these bikes well.

[mikevo]

thats all very well but it been to a bike mec and he cant fix it either and the missus is killing me for wasteing money on it when could have bought a running mot one for what i have spent on this one already ,may just sell it cheap and move on as it doing my heads in now
if it isnt fixed by end of weekend thats what will happen

[VFR..Al]

I would take the carbs off the other bike and try them on it.....that should in theory rule out the fuel problem

well heres a update
tried another cdi started up did exactly same and i thought sod it change the re/rect and restarted and for first time in ages it actually reved so tried old one again stopped reving thought great fixed it ,put new one back and it wont rev
wiggled around with wires to cdi and works to a fashion , so have now changed the whole loom (thats fun lol)and start first time and reved but was late so couldnt give it a good rev

1 question if you rev on spot should it rev out cleanly ??

2 has anyone got a picture of how all the airbox intake flaps and stuff sit
