Just thought I'd throw up a couple of pics of my carbs after boiling them in lemon juice. My pilot jets were partially clogged due to a winter of sitting without properly winterizing (I normally get a chance to start it every couple of weeks for a good garage warm up but this year proved to get the better of me...will be winterizing from now on!!!)
The process is really easy. I pulled the top covers off and removed the slides. Also removed the float bowl and all internals from there (pilot jets, main jet/main jet holder, floats seats and needles, air screws and pilot screws (plus springs). Boiled the carbs in lemon juice for about 15 minutes. After boiling rinse thoroughly with tap water and blow dry with compressed air (helps ensure all passages are clear as well). They'll get really chalky looking as they dry. I took some PB Blaster and rubbed them down with that and they took on a much more normal, albeit dull, look. I was assured by my buddy who's done about 2 dozen racks of carbs this way that they may look dull but will perform like new. That's all there is to it. No toxic chemicals blasting you in the eye because of partially clogged (or fully clogged) jet passages. No toothbrushing to remove crud build up, really no work to it at all.
One word of warning however, DO NOT DO THIS ON YOUR WIFE/GIRLFRIEND/MOM'S STOVE! It makes a rather unique smell that those not predisposed to wrenching will likely find offensive and I'd hate to see you sleeping on the couch!! Still smells better than carb cleaner though!
Bike runs like a million bucks after the cleaning too.
Wish I would have taken before pics as they were pretty grimy on the outsides before the lemon bath.
