May see you down there then. I used to ride there years back and was amazing! I couldn't do much though. Just had massive balls so went at stuff full speed normally resulting in injuries haha

How would I go about checking the feed blocks?

    You say you turned the bike upside down and "a fair bit of fuel came out." Just to be clear, there will be fuel that comes from the carb bowl. That is not a problem, it is just the bowl draining.

  • Check the stator and HT lead then. Although your spark appears ok when out and against the frame the spark is only under atmospheric pressure, when under compression the stator may not be producing th

Here is the spark.. Stick it on HD and should see. I'm doubting its strong enough now?

Has a brand new plug tried 3 plugs. All the same?

Stator? Might be worth getting the specs and checking the resistance. Id check the reeds before this though, as previously said

How do I inspect the reeds? I'm new to bike mechanics so any guidance would be great :)

I can't get that video to work, but try this. Put one plug in the bike, put one in the cap to check for spark and kick it. That way you are kicking under compression with a plug in it and the engine is spinning normal speed, not faster as they do with the plug out and no compression. This will tell you what your spark is really doing when you kick.

Also to inspect the reeds, pull the reed block and make sure the reeds are laying flat to the reed cage, check that there are no cracks or holes in the reed petals. If they are raised up or have a crack or hole they must be replaced.

reedblock is what the rubber boot in front of the carb is connected to with that hoseclamp, just FYI. It has at least one gasket, take care removing, you can make the gasked if you get enough to draw onto sheet of material available an any autoparts stores.

Thanks coop, the video was with another plug in so that's the speed it kicks over at.

Will try find an online guide or video to the reed valves later and see what there like!

Think I'm away this weekend so really want her running today!

Fingers crossed

hope it starts j13me, and remember when using the choke, dont touch the throttle because it will alter the cold start fueling. good luck

Haha cheers guys. Will be home soon and trying again! Offshore this weekend so today is my only day to tinker!

Will pull the reed block out and check them out. Knowing my luck the gaskets will crumble and I will be stuffed!
