Laverda Dave:
Welcome to my VFR400 NC30 thread.

I was gifted this bike by an old work friend last year when she emigrated to Aus. Now the Honda TL125S has departed it is the NC’s turn on the workbench.

This is going to be an occasional thread as I know it’s not a sohc :o and shouldn’t really be here but as its winter and we all get bored and look for projects to follow I thought I’d start this thread.

So, what am I going to do with this NC? Well, I don’t fancy doing a full restoration as it will become a money pit so the idea is to undertake a sympathetic restoration and get it back on the road for the summer.

First thing to do was to strip the fairing off to see what I have got. There are signs of gravel rash to both fairing lowers and although the paint and fairing is original there is a fair bit of pink going on and it looks like a 90’s shell suit so I am thinking of a respray in the original UK NC30 colour scheme (think mini RC30). The bike is filthy below the fairing and all the alloy is corroded as are the fork bottoms and the upper and lower yokes. The frame looks good with no obvious dents, twists or gravel rash. The wheels look ok from 50ft but are full of chips to the rims.

I’m going to attempt to start the engine but will first check the bores with my bore scope and I’ll whip the cam covers off and add some oil to the cams etc. I’ve had to buy a new battery, I think the reg/rec had cooked the old one, it looked like a waffle.

I don’t know how true the mileage is at 18,000 as the speedo is mainly in MPH with KPH as a secondary scale. Considering this is a 1992 model, I’m thinking the speedo was maybe changed when it arrived in the UK? If there are any experts out there on these bikes please let me know.

I am thinking of draining the coolant and replacing it with a litre of central heating cleaner, running the engine up and leaving it for a couple of days to clean the water jackets etc before draining it out and maybe repeating the process. I know these engines fur up if the coolant isn’t replaced with the correct type. Is what I am proposing wise or will it end in disaster, has anyone ever tried it? I know RRC on YouTube restored a NC and he used this method but it was on a stripped motor, my idea is to use it as a cleaning/flushing agent on a complete motor?

I’ll update the thread when I get it started.

Me too!
Looks like most of the lightly corroded bits - brake unions and the like will respond well to a rub with ACF50 or Bilt Hamber Dynax.  Most of the materials in central heating systems are in the bike as well - I would give that a go and see what comes out on the first flush.  Ash might know better.  Pete Hamber at Bilt Hamber might have some sensible advice and suitable product - he's an industrial chemist and knows his stuff.
Another great project for us all to view instead of Strictly come Baking on Ice!
