OK,

I've had my petrol bike stored under my house for like 6 months.
It used to run when I last put it there.
So, as I have moved back to my house full-time, I decided
I stubbornly decided I wanted to get it up and running again.

More so it was calling to my tinkering addiction.
So here's the list of things done to it so far:

1. I put its wheels back on. Big help I know.
This bike actually had a snapped frame, which I had rewelded
before cold storage. So it was many attempts to get the back wheel
to align properly.

2. Test Spark. Yes it has spark.
3. Replaced Spark Plug Cable, with a lawn mower,
variety cable. This was given to me by a guy who repairs
mowers.
4. Clean out Carby. Did a thorough petrol clean out.
5. Try starting with Ether, this did nothing. :mad:

Things to try:
A. Retest spark with current in use plug & lead.
B. Buy more Petrol, fill up tank. This has given a good start before.
I can use same fuel with my Lawn mower and it works fine !!!
C. Buy a new spark-plug.
D. Test Magneto's Resistance.

I have documented this bike issues via vids and posts here before.
But figure all the effort I am putting in needs a new post.

It reminds me why I went an electric with 12 month Warranty...
 
ok you got me, same fuel as before, like six to 9 months old.
it ran in the lawn-mower really well tho.
why is that ?? :57:
they have the same ratio.
 
Mixed gas, esp. the ones with high oil ratios, is only good for 2-3 weeks, then it separates. I pour old gas into the lawn mower, (which has an oil pan) or the car, then mix another batch.

Here in the states, I avoid "cheapie" gas like the plague (water content, non-uniform ethanol standards), and use 89 octane from a major brand name company.
 
I almost lost it, felt like i was going to go over the front wheel.

Ok, new fuel made a slight difference, I get one, two or three kicks back from the engine after getting the bike up to about 15 km/hr. One kick back happened when I was adjusting the choke, felt like i was going to go over the front wheel. :eek:

So, to my next step as above for me,
A. & then C. I'm glad i wrote the list, keeps me on track.

...thanks for listening/reading/responding...

Ok quick update.
I tested the spark-plug and I see spark. point A above.
Tried again to start the bike with Ether, and got no start...
Am buying a new spark-plug at some point soon. C.

I read a post from Bolts Missing, that its possible to have & see spark
and still have not enough spark to get a start. Changing plugs helps eliminate that...

OLD gas will WRECK a spark plug instantly.
thanks for the info...
When you say wreck, would that mean no spark ? or weak saprk
As I was seeing spark last night, you just can't guage how
strong it is by looking at it, whilst holding the plug and wheeling your bike around your back-yard in the dark.
