Honda X8R not starting...

[P.]

Hey,

Got an X8R.

Has fuel, is getting fuel to carb happily. Carb is spotless.
Has compression, more than enough.

Is only sparking when you let go of the starter button, just 1 single spark, whilst cranking there is fuck all.

Any ideas? Its crap weather so thought I'd spend the day fixing, however after making sure everything fuel wise is great, it just won't spark on the button, only when you let go.

It does have some aftermarket bits, PM Tuning CDI so perhaps that is causing issues, however there isn't much you can do with it bar adjust "delay" and "rpm" so I won't be messing with it, no idea what they do.

Any hints/tips/fixes I can do would be greatly appreciated, I'm afraid I'm out of ideas

Dodgy coil?
Tried an alternative plug?

[andys675]

dodgy coil, check there's power going to it

coils are really cheap, £8.50 off the bay

Checked the kill switch wiring system? Ie side stand switch and so on?

[P.]

No kill switch stuff on there.

Could try a new coil, does the same with any spark plug.

Was it running when you got it? What's it like Paddy? Often thought about getting one of these ugly piglets.

We have life.

I just spent a few minutes stripping the coil off the frame. I assume they have lots of spiders in York as I found a family of them chilling on the coil..

I've given it a quick clean up and hey presto, tick tick tick

How to figure out why its not pumping oil

[Vincent]

[Vincent]

[P.]

I shall, however getting to it requires either cutting the frame or removing the swing arm...

Hi Paddy.

The XR8R/S is one of my all time favourite 50cc twist and go's, being a solid Japanese built bike, and also having an all cast alloy frame for cool points.

The PM tuning CDi, will have been fitted to bypass the re-limiters in the Honda Cdi, as they did a very good job as usual with restricting the performance and speed to 30mph.

There's a limiter at 7500rpm, which apparently can be by-passed somehow, but another limiter at 9250rpm, which means that proper reverse cone sports pipe's don't work as well as they should, hence why people fit aftermarket Cdi's.

If pump is an issue you can run on premix until sorted.

Gibbs, what did Duckie look like when he was younger?

[P.]

Premix would be fine, however I aim to run an additional fuel tank, just because So would be ball ache to mix an unknown amount of fuel.

That and I'd have to upjet etc.

If you use pre-mix, make sure it's not running too weak before you detonate the top end. And if you're going to try and blow clear the oil feeds, blow backwards 'First place to look for a blockage may be the bottom of the tank. I prefer clear lines on autolube sytems so you can follow them for any bubbles etc, I don't know why the makers use black pipes...down to £'s no doubt

Pumps are usually pretty simple and there's not much to go wrong, I'd try and get it sorted. When I found it hard to get my hands in somewhere on a bike or car...and he was young enough... I'd get my son to undo stuff Nobody about with tiny hands?
