Forgot a big point that hopefully helps. It all started the other day when i was riding in the rain. My first thought was maybe bad coil or bed coil connection. Once i got home i checked each plug they look ok. The tapped starter to check fire on plugs both blue fire. front cyclinder sparks every time hot blue. rear hit most the time but would lis on occasion. Keep in mind i just bumped the start button, i did not fire the bike up. Plz keep thoughts and ideas coming. Thanks Guys

Your bike does not have a fuel pump … those are found on fuel injected bikes. The accelerator pump noted earlier by Scuba is located within the carburetor. Assuming everything is good on the ignition side of your bike, you are likely in need of a carburetor rebuild.

When pulled the breather off right behind it is a lil brass piece that sticks up and when you twist the throttle it squirts fuel into the carb. Is that part of the pump that we are speaking off? Sorry for some many noob questions. Thanx

The brass tower that squirts fuel into the venturi is the accelerator pump.

As little as you know about the CV carb, I highly suggest you do A LOT of reading before you attempt anything, or take it to someone who knows what they are doing. It's not rocket science, but if you go blindly messing with stuff you will end up far worse than when you started.

Agree. You need a manual if you do not have one yet. There is info in the manual other thenthen the carb that will serve you well.

I have already ran couple more tanks of fuel through it since the rain as well as some lucas fuel treatment. Which did not change the way the bike ran at all.
