Did I buy it as a project off tm?

There have been two 'project' nc30s on trademe lately. I guess he is asking if you picked up one of them

[Icemaestro]

Yup, just being nosey :-)
*and a bit miffed I didn't get one for my 1$ initial bid ;-) haha*

Ahh ok nah didn't get it off trademe. There was one on there with a set of tzr forks and certified not long ago I was keen on though, forgot to log on the day it closed is that the one you meant? In palmy

[Icemaestro]

Ahh..I rode that certed one...tbh up close it was an average job with rust and spray can paint everywhere, leaking fork seals etc, and the fairing kit on it didn't fit properly, hence probably why it had been pulled apart for a track bike.

You didn't get the one that came with a whole spare set of fairings and tank did you?:-p

Nope was that another trademe one? Well I'm kind of glad I steered clear of that one then! The forks practically won me over. Old style forks are my only complaint about the vtr

Hey guys could one of you viffer experts please give me some advice on how to sort out my nc30?

Just got it as a project bike to keep while I sell my other vfr, but it seems to have a problem at high rpm. Runs beautifully right up to 12thousand or so then suddenly starts surging quite badly as if starving for fuel? I just cleaned the carbs and found a sticky slide, got that working freely again, adjusted the throttle positions on the rear 2 and it ran noticeably better, but hasn't fixed the misfire at all! My co worker, an ex bike mechanic, says it sounds like it could be electrical since it's such a sudden, very pronounced problem, but can't say without checking it out himself. Being that it's running like it's starving for fuel, and it's had an aftermarket exhaust and velocity stacks I'm inclined to think that the last owner might have messed with the tuning of the carbs and made a hash up of it. Could someone please tell me to a good place to start looking when I get the chance? I've read that the vacuum set up can cause fueling issues after long periods at high rpm, but the issue starts from the moment you wind it up to 12 thousand whether I've been riding it hard for an hour, or just pulled out of the driveway. Sorry for the long post but I've got a big Easter weekend ride coming up with a couple 600s and a litre bike, so I'll need everything the little 400s got!

Almost forgot; after the surging, it backfires quite badly when backing off the throttle... Another clue it's probably a carb issue, maybe?

It sounds like it's an early model ('89 or 90), which had small 110 main jets front and rear. When I got my '89 NC30 it had a Remus can on it and behaved just as you've described. Chuck a pair of 118 size jets in the front carbs and 120's in the rears, get the carbs balanced and the idle mixtures adjusted, and enjoy

Well you're right about the current jet sizes in it so I might have to give that a try!


Buuuut I don't have the gauges for that. How much did it run you to get them balanced?

[more_fasterer]

Only $50, cos I had a mate do it. While you've got the carbs apart I recommend adding another 0.5mm shim under each of the needles, and drilling out the holes in the slide pistons to 2.5mm. I found these worked well to smooth out the fuelling around the 6-7k rpm area. http://www.akhara.com/nc30/nc30hrccarb/

Haha that one snuck past my daily emails due to the fact its over my price range by a little ;-). Maybe I show the wife that and she'd be more keen on letting me get an rvf;-)

[sil3nt]

Not impressed with the damage to fairing.

[Icemaestro]

I know! what a muppet (whoever it was who did that). though the temptation to blast on it would be massive, and at the end of the day, these things are meant to be enjoyed...however one would think that with a 25-40k bike you would spend a grand on some track stuff to put on it when you did go for a ride/track day..

Here is a video of me and a mate on his Aprilia RS125 at taupo on Friday

Lol, good little battle going on. Loved when he gave you the fingers passing him on the straights. Cool telemetry on the video too
