xivlia's thread of nc30 problems and questions

[Jashdown]

yeah i know. but as i said. ive been taking things on and off at the same time. all teh bolts and shit got mixed up.. so i cant remember which bolts where going where. you se my point Jashdown? . even though im not that good at mechanical things. im pretty impressed with what ive done so far...all ive got left is 2 rear gaskets and that retarted rearset. and im getting the mechanic to fix them up for me as i cannot be bothered lol!

Ziplock sandwich bags are your friend! I've got my engine in pieces right now, if I didn't have sandwich bags, I would have no hope putting things back in the correct place.

You can do the job yourself, it just takes time and patience. Doing the work on your bike yourself is one of the best part of owning it, I believe. It's intimate time with your pride and joy :D do you really want someone elses hands on your own girl?

[xivlia]

haha :D well ive done all i could. its time to get some one qualified to do the last two things..

Also keep yoghurt pots, paper cups and take-away containers! Then you can write on the side or stick a label on.

more and more problems!! okay. so i was riding my bike today for a while. it works really well and runs smooth...i stopped at a set of lights. pulled the clutch in and waited. when it turned green i started moving away..but noticed revs where low...and there where no more gasket leak noise....i came to a conclusion that my rear cylinders arent working? its slow as hell now. this just happend randomly.. before the lights the bike was screaming like hell and pulling away soo quickly... not anymore...however, if i start speeding up faster and faster and around 7k rpm the rears starts to fire again and goes faster and faster. but when i slow down..the rears stop firing and only the front fire...ive done all the carbs stuff fine. the fueling is fine..hmm i wonder whats causing this

well if it's revving over 5500rpm then it isn't the electronic speedo restiction cutout so you can rule out the ignition box.

Either fuel air or spark, wires to the coil haven't come loose?

Why do you assume the rears? Is that just a totally random guess or based upon something.

[xivlia]

well its based on the fact that the rears where the ones without the gaskets. so it was making a wild noise...but now.. there is no noise.. only noise from the can and it sounds all smooth...but slow revs. so im assuming its the rears that have stopped. i havent checked any wires from the coils yet. im gonna let it cool down for an hour or so and get back and see if the coil wires are loose or not.

So what has changed?

You have had the gaskets fitted now?

Your battery is fucked isn't it? Or have you sorted that now?

[Le_Blur]

Have you checked there's petrol in the tank? The bike will start chugging and sounding like a parallel twin when it's time to switch over to reserve.

[xivlia]

hmm i havent checked tank. that could be the case as it shuts itself down when left on idle....erm well the battery must of repaired itself....i turned on the ignition and it worked i was very surprised...i even bought a new battery :\. and no i havent got the gaskets fitted in yet. i was gonna do them today but the mechanic said it would take a while, as i was going to wait. but im going tomorrow with my dad and leaving the bike there so i can get a ride back home with my dad.

If you're saying the rears aren't firing until 7k, a quick test is to start the bike up from cold and feel the exhaust pipes coming from the cylinders to see how warm they are. If the rears are warming up the same as the fronts, then they're firing.

Check all your electrical connections like HT leads and so on, also check your fuel line + vacuum line are unkinked and properly installed.
