I'm in the middle of a rebuild of a 1977 CB 550K and am having a difficult time finding a car rebuild set for it. THe carburators I have on it, and I'm assuming are stock are marked

Kei Hin PD 46A.

The only rebuild kit I have found so far is this one, http://www.newmotorcycleparts.com/fuel_system_parts/carb_kit_hon.html, about halfway down the page. But before I order I want to make sure it's going to fit. Or if anyone has a better idea of where to find one I'm open to anywhere.

THanks
 
Honda makes the kits. Hell i think they are cheaper....
I only use OEM carb seals as the K&L kits are worse then junk, the rubber hates modern fuel, and the brass is always wrong.

The Honda kit is just the rubber, but they also sell the brass. and if you are modding it you need to buy more then one set of jets so that you can tune it.
 
Thanks surffly!! I was able to find them. Now does anyone have any thoughts on Jet sizing? I don't have the stock airbox, didn't come with the bike, so I'll be running K&N Pods that were on it and most like a Mac 4 into 1 exhaust. From what I've been reading 110 seems to be a good starting point.
 
You need to buy a few different sets of jets and learn to tune.
There is no magic jet size as there are way to many variables.
