Met an old timer,gave some new advice
« on: October 27, 2012, 07:49:53 am »
I met a guy who was a fan of the Honda CB's. Stated he has had one since the early 70's. He asked if I drained the bowls for winterization and I informed him I do. He started goin on about how this is a mistake. Leave the gas in there he told me. By draining the bowls, the rubbers get hard and won't seal properly. He stated the gas saves the integrity of the rubbers and gaskets.

True??????????

Sounds right to me. I never drain anything for the winter.

The last 750 I bought had been stored for over 10 years.  The bowls and tank had been drained and remained perfectly clean.  However, someone had also loosened all the carb and airbox boot clamps.  I just tightened up the clamps and added gas...and the thing started right up and idled perfectly.  Further road testing revealed it to run like new as well.  So i would guess, draining the gas and doing something to protect rubber parts is beneficial for long term storage, probably not necessary just for the winter.

Same here but I would agree that draining them is a good idea for a long term storage as in 1+ years. When I first took the carbs from my 550 apart it's bowls weren't drained and had sat for who knows how long. What gas that was still in the bowls had the consistency of molasses and stunk to high heaven. The smell of varnished gas is hard to wash off. :)

I drain my carbs every winter.  I have yet to have problems.  I also use Stabil in the tank.  I fill the tank with premium in case I lose any octane from storage.  No rust in my tanks.  I store them in a heated shop,  but I understand not everyone can.   I use regular gas without ethanol during the riding season.

OK, maybe I'm missing something here, but how on earth is letting gas sit in your float chambers going to "protect your rubbers" or whatever. Exactly which rubber parts are we talking about? Even the chamber gasket is probably not in contact with any fuel once a bit has evaporated........not to say I disagree with not draining the gas for short term winter storage, which should be no problem regardless, but I am questioning the reasoning mentioned.

I've had a few bikes that sat for long periods without gas in the tanks and they rusted right out, I'd rather they left gas in the tank, I can clean a tank but rebuilding them or relining them is a PITA!
Carbs I'd rather have drained as they gunk and green up inside, brass fittings seem to survive better when left dry.
I think the thing I most like about motorcycling is the speed at which my brain must process information at to avoid the numb skulls who are eating pies, playing the ukulele, applying make-up etc in the comfort of their airconditioned armchairs as they make random attempts to kill me!!!!!!!

Use Stabil to protect your tank and be sure to fill it before storing for the winter. Or run the tank dry/drain it. Condensation from moist air will ruin a tank. Might not show up initially but just wait - pin holes atound the bottom seams.

And, if you turn your petcock OFF you can expect the bowls to evaporate and leave residue unless they are drained first. That brings up this oldtimer question - do your float valves/seats leak? If so you're not going to leave the petcock on and the bowls will dry out through evaporation.

I say when parked for any extended period to run them dry and drain remaining gas, eliminate residue/varnish, and keep the jets and passages from gumming up.

WRONG .....that was before gas had ethanol in it that attracts moisture.

I agree with CoachDoc.  The gas in the float bowls is not high up enough to touch any of the rubber parts inside the carbs. 

I stabilize the fuel and usually shut the petcock off while the bike is running, so there is gas in the tank but not the carbs.    Ethanol can turn in to orange gum.  I never tried to crack the float drain screws loose.  Re-connect the battery and it fires right up in spring.

You cannot adjust a clutch. You can only adjust WHEN it
 engages with the lever on the handle bar.

If the clutch is slipping it cannot be "adjusted " into being useable.

It's not slipping. I have a hard time putting it in neuttral after being in first. Not hard clunking or anything... Just have difficulty putting back in neutral. I've had it where it engages right away and when its damn near at the end.

I've actually never messed with mine, so I don't know how much help I would be.  But that's not to say I wouldn't mind helping out.  Didnt' even see you were from WI!

I guess you do what works for you. I've never drained bowl or tanks over the winter and have never had a problem at Spring start up. If the bike was going to sit for years, then I would drain the bowls.

My reasoning for not draining the bowls for the winter is simple and has nothing to do with protecting rubber, I just don't that's all. :)

It is all about the amount of time. Here in NC even in the dead of winter there are times when I can go for a ride. So my bike might sit for 3 weeks at the most. I start it up with my generator if I can not ride just to heat it up and dry it out.This takes a while even in winter I use a fan after a few minutes. The fuel from both gets dumped into the car in the spring. Just keep the fuel rotated and all will be good.
