VFR NC30 Starting problem

[wernerweber]

Hi there, I am new to this forum and hope someone can help me.

I have a 1992 Honda VFR400 NC30. The bike is very well maintained but I am having what I believe could be an electrical problem, but I am not very technically minded and the support for these bikes in South Africa is limited.

The bike starts fine when it is cold, no need for choke or anything. After riding for a while then sometimes when I try and start it again, it just turns and turns but the bike does not start.

I fiddled around by the clucth (there is an electronic connection there) and then sometimes the bike would start but on other occasions it just turns and turns with no avail.

Has anyone had a similar problem?

Many thanks

Could the carbs be getting 'heat soaked' causing the fuel to evaporate in them when hot? Not sure what the solution would be if they are, perhaps some heat reflective foil between the engine and carbs. Rare for a simple electric problem to show up like this (OK cold/ bad hot). Is your choke operating ok, and importantly returning to the 'off' position fully? Here I mean the mechanism, not just the knob or lever.

I am not sure if it could be that. Because I've gone riding and let the bike cool for at least 2 hours before trying... then it won't start, but try the next morning and she's good to go.

I just read something about the kickstand being out etc before a bike would start... I've only recently started biking and not sure if the VFR has that requirement. I cannot remember if I've tried to start the bike with the stand up or down.

The NC30 doesn't have a side stand switch (that is why it has a little rubber tail - so if you ride off with it down in theory that will flick the stand up before you wipeout). So the bike should start and ride with the stand down. It won't start in gear however unless it's in Neutral or the clutch is pulled in. This is what the "electrical connection" at the clutch is for, it will prevent the bike turning over if it's loose.

I don't know if you try this already or not, but when I had a NC30 if it was still warm it wouldn't start without giving it quite a bit of throttle (Choke off). When Cold you didn't need to touch the throttle at all but the Choke was usually required.

I never really had that problem. The bike is in a pretty good condition and even on a cold start I've never had to use the choke. I'm gonna go experiment today a bit and see if I can get it happening consistently.

Thanks for all the advice thus far.
