Strange thing with my NC30

[arj127]

I was travelling along the motorway today for about 40km when my VFR400 started to run like it was firing on two cylinders and came to a stop not long after. After waiting maybe 10mins i fired it up and continued my journey. When i got home it started to do it again. Has anyone had similar problems? The tank vent is working. Not sure where to look at the moment.

Start with the real simple stuff...

Has it got plenty of oil and gas? Filters all unblocked? Jets in your carbs?

Ummm, Mini_me was having similar sort of problems. Not too sure if he has worked out what was causing them. Maybe flick him a PM to see if he has worked it out yet.

Hondas had electrical problems once upon a time. In the 80s i think.
It mite be your CDI thts the problem. Cousin had a similar problem on his NS250R. Intermittant then eventually died altogether. But you mite wana check for a blocked carb and spark plug and leads. Just remember start with the easiest and cheapest thing first and work your way through the components.

Check the coils.

I could almost guarantee it will be the rectifier/regulator. Hondas are notorious for it. Had them go on both my NC30 and my CBR600F2. First the engine starts to sputter then it wont even run, next you lose all electrics cause your battery aint getting charged anymore. I would suggest takin it into a bike shop to check it out before it conks out on you in the middle of nowhere.

Possibly the fuel tap. Used to get that sort of shit on my VFR. The diaphragm inside the tap was worn so the vacumm didn't open it anymore and it'd starve of fuel.

Will check the voltages tomorrow. Has clean air filter, new oil. Will chuck new plugs in and try again.

Follow my threads...

Hmm id start with saying it could be a lack of fuel. You'll be going along and it'll act like its running out of gas eh. Check fuel switch,filter and lines.
Your carburettor could also have some junk in it?

When the reg/rec went on mine IT JUST WENT=boom. I didn't get any warning just one day it decided to pack up Chucked in a nice big Yamaha one and its been all good since then

True dat, but I would be thinking that most of them would have been fixed by now? I dunno. might be a problem with the plugs and points. Had to ziptie one of the plugs down cause it's in need of a new point case thingee, stopped the missfiring.

From memory the BMW workshop manual advises that in the event of any irregular running first replace the fuel filter. It seems that in the majority of cases this will cure the problem. A relatively inexpensive place to start...

its a honda right??? yer.....you'll find that like most lawn mower engines they stop working for no reason at all....I usually find attacking my lawn mower with a axe and plenty of swear words.....if that fails.....throw a match in the petrol tank and fry some marshmellows

[IronicCapers]

mmmmmmmmmmmmmHH marshmellows. Watching a lawn mower burn is quite satisfying but after tht i realised i needed to buy a new 1

Bike shop certainly knows how to charge for them. Got the multimetre out. Battery showed healthy 12.98volts with engine off, then steadily increased to 18volts at two thousand revs. So i guess the reg/rec is stuffed after all. Anyone know where to get one at a reasonable price?????????
