nc 30 not running very well

[Cammo]

started taking the cars apart and all just full of crap, cleaned all of that away and found in the front a 115 main jet and 35 piolt jet, in the rear is a 118 main and a 35 piolt is this right???

That's correct. Standard jetting for a late model nc30. Going to 118 front and 120 rear would suit your can better.

A very good chance all that crud is casuing dramas!

ok mate thanx, where can i get the jets from?

[Cammo]

Any Keihin dealer will have them, or most dyno places.

Rick Oliver is a member on here (look him up) and can also supply what you need at a good price.

While you have the carbs off, good time to check that the pilot screws are set right. They should be all set at 2 turns out (standard setting), most peeps set them at 2.25 turns out to suit an aftermarket pipe.

just got the carbs done and put them back on went round the block and the bike ran worse that before (same sort of thing but much worse) cleaned everything out, the only thing i ain't done is the plugs because thay ain't turned up, any one think this will help???

[Cammo]

Check that the carbs are seated properly, good chance an air leak is responsible.

I use a torch and inspect them carefully. You could also spray wd40 around the base of the carbs, if it has an air leak the revs will rise.

hi all put some new plugs in and run lots better but still not right, still sort of misfires, no air leaks or anything, getting the carbs syncronised at the weekend hope that helps, if not on the dyno

Did you clean out the pilot jets so you can just about see daylight through them ?

I normally use a single strand of fine wire.

cleaned everything took me ages,

[Sligeach]

any chance that you cleaned them meticilously, then put the same petrol in and that is wherein the problem lies? is the bike kept outside not under a cover? has it been sat up previous to you have it?

[dalby1988]

it is kept in my garage and the person that had it before me said he it was sat for 3yrs,
