brianmacza Posted August 8, 2024 Posted August 8, 2024 Redoing my '97 - 278k Km so far and she's weary Redoing paintwork, fork seals, steering head bearings, replacement front disks, replacing the rubber brake lines with braided steel lines, new cush rubbers in the rear hub with new sprockets and chain, and new emulsion tubes and jets/needles in the carbs. Bike is stripped down almost completely already, but I can't get the FUCKING CARBS OFF.... the rubbers are almost bakelite hard. Tried WD40 soaking already, but that just made things slippery. No movement in the damn rubbers. Advice? Please? Quote

RXX Posted August 10, 2024 Posted August 10, 2024 Where are you getting your parts? Partzilla is being very easy for me to use. I am doing something similar as you. Quote
tomek Posted August 10, 2024 Posted August 10, 2024 IIRC brianmacza moved from South Africa to one of neighbouring countries. Partzilla might not be an option. Quote

The boots I did were much thinner so they probably soften much faster, but they also needed to be much more pliable to be able to fit them. Carb mounting boots just need to be less than rock hard. They will re-harden, but it shouldn't matter 'till the next time the carbs need to be removed. The down side is that I don't know how well they'll re-seal to the head. If they use an o-ring that's a simple solution. If they use the molded rubber as the seal I'd probably coat them with aviation sealer. Quote

Just clean the shit very well, preferably with, of course, small amount of acetone. If you wipe out quickly it won't hurt nothing. And use some sealer. It is not like it is forced induction. Pressure differential is not that great. Should be good till next removal. Quote
superhawk996 Posted August 11, 2024 Posted August 11, 2024 The pressure differential can be as much as a forced induction motor, probably 10 PSI or more. Quote
tomek Posted August 11, 2024 Posted August 11, 2024 Technically yes, but only during shifts and engine braking operation. Quote
