Having just been given an estimate of about $800 to $1200 to service my carbs (at a Honda dealer of course) I am looking to do the carbs on my bike on my own ;-) I have found excellent directions and great tips in this forum - my plan is to buy a full set of used, not jetted carbs...and get those cleaned and serviced, then swap them onto my bike - I found a decent set on eBay, but the seller is not sure what year these are from - I have an 89 and would think that carbs are the same for 87 to 89? Can any of you carb experts take a look at his link... maybe you can tell if these are the correct ones for 89 model? My vote is yes... but I wanted to ask some opinions here.

THANKS!

 

Hello. I just did the carbs on my 1989 CBR. Those in the link look like they are for 87-90, so your good.

It is actually not as hard so you it seems to do the carbs. After a bottle of carb cleaner ($3) and air-in-a-can ($7) I got my carbs cleaned and back in. Then I had to get a used fuel pump and that was $40. so in total I spent $50 to re-do my carbs and now i'm about to spend $35 on a carb-flow-meter (http://www.cbperformance.com/catalog.asp?ProductID=572) to synchronize my carbs. So definitely do it yourself if you are able to pull them out and know your way around a screw driver.

Good luck.

 

they look like the right carbs
but,
does you bike has emissions equipment?
these carbs might/might not be set up for emissions.
ask seller for the number stamped on side of carb
should be something like VG20A

 

Thanks guys.. I did ask the seller to let me know if there were any part #s on the body so I could reference it against mine or the OEM microfiche. As for the emissions, I did not even think of that. My bike was purchased new in NY state and I am the second owner.... I would imagine that it does not have the extra emissions tubing, etc. Is there some way to tell if they do or don't have the emissions features?

And WISH, I took a look at the air flow meter you posted the link for... How does that work? You just adjust each carb one at a time? I thought that the manometer with four hoses was needed so that air flow could be regulated in relation to the whole set of carbs, and not adjusted one at time? I am still learning about all of this stuff. Thanks for your reply.... I am hoping that any carbs I buy will be okay after being stored dry for a long period of time, but I can re-use the good rubber boots and seals from my carbs I suppose.

 

i was the one who suggested that too to wish.
i have used it to sync my carbs and it works great. yes you can only adjust one carb at a time. but its pretty simple to use, you just hold it up to the opening of the carb, take a reading and adjust.
if your bike has emissions equipment, it will have a box thing by the header with tubes going into they cyclinder head, and some more stuff connected to the carbs. if you dont see a box and a bunch of tubing up front you dont have emissions. even if the carbs are set up for emissions, it would be pretty easy to cap off the ports.

 

You cannot use 87-88 (pc19) carbs on your bike. Or you can, but the bike will be slower. 89-90 (pc21) have bigger carbs than the PC19.
