wont start

Can someone explain how the choke works. I am having a hard time understanding what it does and how it works.

Hi Matchless & Rustybronco. I`m sure the choke works ok, like I said I only need to use the trick when the bikes been stood a few days. If I`ve been riding say the day before, in cold weather I have to use choke to get the bike started next day and it starts ok. I know that a lot of people don`t clean carbs properly, but believe me I`m pretty thorough. I`m certain that all the passageways were cleared when the carbs were stripped. Also, all three of my older bikes need blow starting if they`ve been stood, can`t see them all having the same blockage. I am intrigued as to why the trick works too, but at the end of the day it does. When I see a post about a bike not starting, or if I`m out and about and see someone having a problem getting one started, its the first thing I suggest. Nine times out of ten it works. At the end of the day, getting the bike started is all that counts and provided it runs well, where is the problem ?. And to be fair, my chopped GS was built in 95, had to blow start it to get it running then and been doing so ever since, still runs like a dream.

Thats very interesting. I have never looked at how the choke is affected if the floatbowl is low. If you have evaporation of fuel rom the floatbowl and a vacuum petcock, usually such a problem is sorted by putting on prime to start. I am just shooting in the dark here, but as you say it works for you and you do not mind doing it so thats OK.
Makes me think of those alcohol test things that were on the market and your car would not start unless you blowed in it and was under the limit! Some called it "Quickstart" ands said they were just giving it a high octane boost!
Thanks for all the replies and if you ever localise the issue let us know please.
Keep well.

My comments were of a general statement, not directed at you. my apologies if they came off that way.

Also, all three of my older bikes need blow starting if they 've been stood, can`t see them all having the same blockage. I am intrigued as to why the trick works... too

localized fuel volatility issue? fuel evaporating after a few days?
I wonder how many factors may be involved...

Hi rustybronco. Sorry, I did`nt mean to come across sounding offended or defensive, I know you were`nt having a dig or anything. You are right though in that there must be a reason for it. Thats the trouble when we write, can sometimes come across the wrong way. Much easier if we could sit down with a beer or two to chat about these things.

You buying? I'll bring the wrenches!

Ok with me !. Could be a long walk and quite a bit of swimming to get to the pub though !.

Hi Raider. Before doing any work on the carbs, try first turning the petcock to prime for about 30 seconds then turn back to the normal position, then put on full choke and try to start her up. If that fails, try blowing into each of the two carb breather pipes a couple of times. Pull on the choke again and try the starter. Some of the other guys are probably thinking "oh! not again" as I`ve posted this tip a few times, but its helped get a lot of bikes going too !. My GS 750`s won`t start without a "blow job" if they`ve been stood a while. Worth a try !.

Thanks for the tip.
I had gone through just about everything electrical to no avail. I saw your tip and it worked. It only works however with the fuel cock on prime. But it works. Thanks!
