NC30/35

[Indiana Jones]

The whole motor is unpainted alloy.
It was my buddys VFR. When he had it,he took a test ride on his mates low mileage RVF and proceeded to wreck the water pump when the chain came off.
Sale had been agreed to a 3rd party when the shit hit the fan,so a swift motor swap was carried out with the agreement of the buyer for a reduced price.
The water pump was repaired,the motor was freshened up with new rings and valves.
The CDI is riveted together with 2 plugs.
It's VFR electrics for sure.

I really wouldn't worry about it, the RVF is probably better gearing for the road (lower 1st), slightly lighter internals and the VFR is/was more powerful so you're not likely to be losing any advantage other than missing out on the minor extra midrange (but minor lack of top end) you'd get with a full RVF setup.

Thing is, it's a race bike.
I want the best setup available.
I need that midrange.

If your racing it Rvf engines make the most power....simples

Rvf engine, vfr gearbox and nc30 carbs is probably the best combination for track speed and top end horsepower.

I wouldn't worry too much about the cdi mismatch to the rvf engine, get an ignitech adjustable cdi and it'll be a good un!!

Or better still junk the loom and build up a race one, dead easy

How sure are you it is an NC35 motor?

Looks like just replacement clutch and genny covers to me?

is the whole motor unpainted? Cannot tell from the youtube..

Thats why I asked for the engine number :D My train of thought

Nah, straight swap apart from the electrics, only difference is the middle of the V hole isn't used and isn't tapped on the NC35, you need to tap it if you want to fit the engine properly (or just not use that bolt).

Druid

Ah its just tapping the hole. Useful info

So, by my reckoning, to get the full potential from my RVF motor,I need the loom,CDI,pick ups and rev meter?
I'm sure the RVF motor running with the VFR ignition is not great? Can anyone supply some information as to what the effect of this would be?
What differences I would see with the matching loom?

Can anyone point me in the right direction for parts?

I've already PM'd abrmoto,so if anyone has any RVF electrics laying around,let me know.

You keep on about Full potential. What were saying is that if it doesn't already have the the pickups already it wont' run at all. Unless its an NC30 engine If you change the loom you can use the NC35 CDI but you'll need the rev counter. You may as well just get a programmable ignition if you want 'full potential' :)

I thought my posts were clear.
It's a race bike with an RVF motor and VFR carbs.
The RVF motor works with the VFR loom because the VFR pickups are installed? Correct?
Are you saying that I have the RVF pickup already?
Thr RVF motor has different cams,compression,intakes to the VFR.
To the best of my knowlege, because of the different engine config,the ignition map for the VFR will work,
but won't be matched to the RVF motor.
I have the ideal package apart from the fact that I have an NC35 engine that thinks it's an NC30.
I need a loom to connect the correct CDI,pickup and rev meter to?
I was under the inpression that it would only run if the VFR pickups were installed with the VFR loom?
It's not a road bike,it's a pure race bike, I couldn't give 2 hoots about the road setup.

[quote="viper_biker"]An NC35 motor and MC30 loom/CDI shouldn't work together, unless its had VFR pick-ups fitted to it. If you can put up a pic of the motor, CDI and the bit of the loom that connects to the CDI then that will tell all.

This is what I'm going by.

[CMSMJ1]

If you have a VFR CDI then you must have the VFR pickups installed too.

You cannto fit the RVF CDI to it and plug'n'play. You need to stop worrying about it so much - if you are concerned, then buy an ignitech programmable CDI and get that setup properly.

The engines aren't that much different IMO and you'd be better fitting an NC30 gearbox to it if you were extremely serious.
