Honda CBX........???

[Led]

I had a CBX 6 cylinder before the buying the Valkyrie.  I sold it to a Guy I know, 35 odd years ago.  He gave me first opportunity at it, and now it sits back in my garage!!

BUT.....He allowed gas to sit in the carbs for 4 years.  He allows that He had NON ethanol fuel in it before parking it.  So that helps....maybe??

IS there something I could fill the float bowls with, and let soak over the Winter?  Then drain.   Then try and see if it will run again next Spring?  Maybe Techron or something?

I DESPISE the thought of having to remove those carbs.  It is a REAL sucky job!!  Lol!! You basically need to tip the whole engine down in the frame.  Makes removing the carbs off the Valkyrie look EASY!!   I am willing to just gamble first, that they may still clean up well enough again.......??!!

Well you have all winter.

  I use Berrymans B-12.  If I have a borderline situation , 50/50 gas and B-12. I use an IV bottle. Drain fuel tank and do the oil mist if it's not rusted. Drain carburetors. Hook up fuel supply and open carb drains until fuel flows thru.  You can leave it for a week or so and then try to start the bike. It can be done a couple times.  It is worth a try.

I agree with da prez. Don't allow the b12 to sit all winter, short periods of time is best.

Yes, it is a HUGE gamble.  Never made a dime at a Casino either.  Even if one CV slide is stuck.....OFF come the carburetors!  Odd's are not in my favor one bit.   

A LOT of work in my future, on a bike that is not easy to get running right.  But......I DO have a lot of memories on that saddle!!  STILL!!!   Strange that it is back in MY garage!   I thought after  all these years, it was long gone somewhere......A Guy sometimes regrets selling a Bike, and always wishes it was back.......

But I wish, it was one Bike that was a lot less, "complex"!!!   Lol!!!!  Thanks Gentlemen for the info......

I would use TC-W3 in the fuel. will clean everything and doesn't affect the o-rings and seals.

""What we are trying to accomplish ( The deliverables)
We need to lubricate the fuel pump/seals/injectors.
We need to clean the fuel system and scavenge water that ethanol attracts.
We need a film of protection in our fuel system to stop corrosion.
We need a cleaner for our spark plugs/valves/combustion chambers.
We need to clean the ring packs
We need to leave a film on the cylinder walls to eliminate cold start metal wear.""

I used Berryman's Chem dip in my Valkyrie.
Remove the fuel tank.
Drain the carbs.
Set up a supply hose and funnel to the fuel line.
Fill the carbs with Chem Dip.
Drain after 1 hour.
Triple rinse with fresh gas.
Reassemble and hope for the best.

Worked for me. The bike was new to me about 5 years ago and has run great since the clean out. I always add 2ml of TCW3 for every liter of gas per fill.

         There is a product called RXP you can buy at Auto Zone or Orielly's that I have used. You may have to ask for it because they keep it behind the counter sometimes. I heard about it on a car talk show many years ago. As far as unclogging a carb, I think it is superior to most of the other stuff. I used it in my Roadstar many years ago, the idle jet was clogged and the bike would not idle at all. I road the bike about 60 miles after using it, but it had to sit over night to work.
