"If you remove the tap does fuel flow ?" Good question. I'll check that out. Can't do it right now. I'll pull the whole petcock out and see if...
This bike was in the shop. I found out the needles weren't closing the fuel flow. They are replaced. Floats are set to 7.3 mm. Replaced the float...
[ATTACH] I made a fuel line setup with a built in filter. I finished it yesterday. But, still no start. I opened the drain on a bowl and nothing...
I've got a design and I have ordered parts. At the petcock I'm going to adapt the close to 1/2" spigot to a 5/16". Then everything is easy to...

We have sparks all around. Got part # 16953-ML0-034 ordered, brand new.
My petcock diaphragm and cover are wrecked. The spring is gone too. I get to source one tomorrow. Maybe the petcock was dumping fuel. I will still...
The eek! Emoji is right. A plug pull and at least I found something to fix.
Finally, got to the garage. The bike is running Champion RA4HC plugs. There should be a photo on this post. They running very rich. I've got a...

Thanks, Redcrow. I'll check that out.
Stub stunner - Holland Tunnel, I haven't been there in years. I'll try the sprayer and check the intake as you suggest. Also, I'll look at the...
