nc30 fueling issues

[marcus57]

Have a strange issue with my type 8 , chasing Ricky when leaving cosford yesterday the bike just gave up on me.

Considering i had been traveling at decent speed on the way up there with no issues it seemed odd.

I was in 6th gear just over 10k rpm and it died , wouldn't rev and sounded like it had dropped to 3 cylinders , gave it a couple of mins to idle and all was good. It also happened to me again on the way home but when i stay bellow 10k rpm it is fine and runs lovely .

Also at lower rpm's the throttle is very snatchy , the bike did have an ignitech fitted and has a full micron so i assume the carbs have been played with.

Im guessing that im going to take them off but what sort of settings should it be running .

I had that on my Seed, check the carbs but mine was the rubber flap was missing, fitted it and it sorted it instantly.

I will have a look for the flap , never thought about that.

I hope it aint the carbs as i really cant be bothered to strip them.

Well I suspect you will have to if it was running a full micron. Unless you put the micron back on. But to be honest it's easier to set the carbs to exhaust.

the micron is still on it , just the ignitech that i removed , i didnt think that would affect how the carbs had been jetted for the system.

Or they have just plonked the micron on and not touched the carbs?

[marcus57]

considering the other bits and bobs that were fitted to the bike and the bloke i bought it from seemed quite swithched on i would assume that it had been done.

I have a standard system to go on at some point so theres no point in setteing the carbs for the micron if its coming off at some point .

Just found this from the advert when i bought it.

' Carbs fitted with RO replica needles and various Honda cottage cheese screws replaced with stainless allen screws. '

[ibby4585]

RO replica needles what are they? Lol .

Get them apart for a quick clean and set up and get them back on. Check the rubber flap whilst they are off too

[marcus57]

Well it's got a rubber flap so it must be carb related .
