Default POW! Carb Back Fire

Hi All

Sunday 11/23/03, late evening, getting ready to ride home from work in San Francisco, I started my 2000 FLSTF and got a rather large back fire in the Carb. When I pulled out on the street I had no power but the motor was running smooth. Pulled the carb off and found a blown slider diaphragm. It had a 3/8 inch hole blown in it. Anyone experience this? 30 Bucks later, I’m back ridding again. Strange things happen. Harley Dealer wanted me to bring it into the shop. No Way Man. Their labor charges are high and I always end up buying more stuff. They always have my favorite color on their parts “Chrome”.

Never heard of such a thing. Hear of the carb backfire, or "cough" we call it around here, but never heard of it breaking parts. Glad you got back on the road.

I have never experienced that, but I do now about the slider diaphragm. A couple of weeks ago I purchased the small round chrome cover top for the CV carb to replace the black one. Once you take off the diaphragm it is difficult to put back on because it has lost its shape from the constant use, so I had to fork over the 30 bucks and replace it with a new one. It fit like a glove.
So if anybody is thinking about doing the same, be ready for some
aggravation or be ready to buy another diapragm, and by the way they sell the whole part with slider and not just the rubber diaphragm.
Another lessoned learned on my part.
I have also stayed away from the dealer, I seem to come out with more then I wanted, and spending more then I wanted to!!
Ride Safe veryone!!
