Hi
Had a few days off, so have had a good go at the bike.
From a completely stock kit, I have added a Jaguar CDI, a voodoo pipe and a walbro carb and reed valve. I have also mildly skimmed the head, and gently polished and opened up the ports and outlet. (There were casting defects inside the ports, which I have tidied up, without altering the height or size of the ports.) I also brought a better (NGK)plug, but its the hotter type...I fear I should have the cooler one, but its only £3 if I need to change.
I had to drill and tap the transfer port for the pulse pipe for the walbro.
It started nicely, with a pleasing crackle though the new pipe. It starts well and so far I have let it warm up, and ridden a bit around my house, but not far. I can tell though the power has increased noticeably, just at low speeds.
I found that the walbro carb would not idle down at it's factory idle, adjustable by the pointy screw. To get mine to idle, I have had to adjust the throttle cable, pulling it open, so that the cam is maybe 3mm off the screw, which is a lot of its adjustment. However, its idling nicely there.
The carb is set at the walbro website recommendations of 1 and 1/2 turns back from seated at the mo, and is running, but predictably richly. Quite Smokey.
Any Advice?
Many Thanks
Is this to do with the reed valve? Somewhere I have read that they will affect the mix?
So far my carb is running at the
