Hello everyone. I have a new and interesting problem. Recently my baby will not start . Took it to my local mechanic and he diagnosed that the ignition pick up/pulses coils was bad . He replaced the coil, it’s start up and I took home . Have not ridden for a month ,put in new gas , but now it bogged down when I throttle  up. Needing some help and guidance.its feel like fuel issue.  I tested the petcock and it was okay.
Took the spark plugs out and the right side (all 3) is darker,more carbon bill up then the left side.

Valkyrie’s don’t like sitting for a month. Put a strong dose of chemtool B12 that should improve things

I've read posts from a few guys on this forum about using a strong dose of Chemtool B12. I've used the recommended rate of 1 oz. per gallon with good results. Just wondering what constitutes a "strong dose"? 2x the recommended rate?
Also, Berryman makes a B60 product for fuel systems that have been sitting/neglected for a long time. (FWIW, their definition of neglect is a fuel system that hasn't been cleaned or treated in over 3,000 miles.)
Has anyone tried the B60 product on a Valk that's been sitting for months or years?

If I remember right. A bottle treats 15 gallons and I put half a bottle in a full tank. That’s my definition of a strong dose.

I avoid using a strong dose of B-12, etc. My theory is strong doses may loosen big clumps and clog up things. After several rinse cycles a strong dose won't hurt. Abeit by then a strong dose won't be necessarily.

My recommendation for storage is Marine Stabil.

When I bought the Bruce bike. BF tried but he couldn’t  keep up with keeping her running. It sat for a long time and barely ran when I got it home. It only had a quarter of tank of gas so I filled it and added half a bottle of B12. Took two days to ride out that tank. Filled and added the other half. By the time I rode the second tank out it was running perfectly. Just my story

Makes me wonder what's in some of those additives.   
   I think B12 has a bunch of light aromatic solvents, kind of like toluene and the like, but the others, Techron, Lucas' product, Gumout and others have very little smell; some even advertise that they use jet fuel for the main component or carrier, which is a lot like Diesel fuel...
  I'd like to hear what a chemist would have to say.

Bottom line is B-12 does a better job than other fuel treatments, smell test or taste tests not withstanding. Costs half as much as Seafoam which was the only thing I used until Seafoam doubled their price, stupids. I haven't tried Techron. But B-12 is cheaper.

Best fuel treatment is acetone..dont use much and run most of the tank dry..if your going to let the bike sit again.
