Keihin pd carburetor

I used a wire basket over a clean oil pan in case I needed to drain out fuel. Considering the float bowl has been draining out all its fuel, this proved to be keihin pd carburetor. First I removed the drain screw.

Most of these carburetors have the same external dimensions as the OEM 26mm PD carb of the CRFF, but are outfitted with accelerator pumps which squirt fuel when the throttle is snapped open to greatly enhance throttle response and reduce bog. These are an easy upgrade from the stock carburetor, as they fit in perfectly. Just Search eBay for XL carburetors , as there are a variety available. The PDA is a 28mm bore, compared to the 26mm of the stock carburetor, which means it should rev out better but might not make quite as much low RPM power at wide open throttle on a stock engine.

These things are all years old. The float bowl was next to come off. Having run out of shed time for the week, I labelled a couple of zip-lock bags appropriately.

It's been a while since I've been on the site, but felt compelled to make a new thread on the F since Honda changed the stock carb from the well known 26mm to 28mm Keihin. A very close personal friend of mine just bought a brand new F, and it comes with a different stock carb than what is on most other older 's.. The new F comes stock with a Keihin 28 mm "PD" carb. I plan to remove the snorkel from the airbox, and uncork the exhaust. If anyone out there in F land has already rejetted a , please let me know if it required different jetting. I will post some pic's of the F later today. And will also post a ride report on the performance improvement once we get the bike properly jetted.

Most of these carburetors have the same external dimensions as the OEM 26mm PD carb of the CRFF, but are outfitted with accelerator pumps which squirt fuel when the throttle is snapped open to greatly enhance throttle response and reduce bog. The choke on this carburetor is actuated on the right side facing out when installed on a CRFF and it changes the idle speed when it moves. I also have a few other projects going right now, so may start a separate blog for those. The rest of the throttle linkage was removed from the throttle slide and the needle jet removed The needle jet was stamped 77A. Does not use the same main jet type as the OEM keihin. THe gasket still seems to be in pretty good condition. The mounting screw was removed. I moved on to removing the jets and fittings. So the lever, spring washer and nut came off. The throttle slide and needle were disconnected from the throttle linkage arm. Considering the float bowl has been draining out all its fuel, this proved to be overkill. Share this: Twitter Facebook. The top cover was next to come off.

I thought I'd share my experience installing this nice carb kit as it was not a "simple bolt-on" process. Also, there is not much info on this carb in the forums. Hence the tags above to help the search engines.

I moved on to removing the jets and fittings. The top cover was next to come off. It was followed in short order by the throttle spindle and its spring and washer. The rest of the throttle linkage was removed from the throttle slide and the needle jet removed The needle jet was stamped 77A. I removed the float valve and inspected the flot bowl o-rings for obvious signs of wear. Skip to content. These things are all years old. Like Loading No jet access without removing the float bowl, which is different compared to the OEM carb.
