Hi,
I was just going to put some washers under the needles on my nc30 but there are already some in there, should they be there as standard or has this mod already been done? I hope there not standard as it will save me taking the rest of the carbs to bits!
Many thanks

Ian

I am sure that the NC-30 is the same as the NC-35. Standard shims are .5mm. So you can either add an additional .5mm shim for a total of 1mm, OR remove the standard .5mm shim and add a 1mm shim instead.

I did not even have washers on my nc30 needles for some strange reason.

Did you look inside the slides? Sometimes they stick to the inside end of the slide so when you pull them out they are not attached to the needles. The ones that clip on are different, but these just slide on the needles.

where is the best place to get these washers?
I had some of the 0.5mm ones fitted when I got the bike.
Now I've fitted a yamamoto system it seems to bog down in the mid range slightly - will 1mm's worth of washers help?
Or is it a case for new jets and needles?!!

Not sure about a full system, the 1mm total shim is what seems recommended for a race can only with no air box changes.

Best place to get them is Mr. Rick Oliver.

Hi,

Cheers
