1988 carb question

Postby franksquires » Sat Jul 11, 2015 10:10 pm



Visiting an old subject I realize, but does anyone know if there is a more or less plug and play carb set-up to replace my 88 1500 carb set? I havent started to delve into the problem yet but bought an old wing with backfiring carbs. I have read as many posts as I can but, just wondering is there a replacement fix that I can just swap from a more trouble free design?

When I first started with my 88,I did locate a later 90's carb set locally...It was suppose to be "rebuildable" and the seller wanted $500 for it..
The 90 and later models redesigned the carbs and airway plumbing internal...they seemed to work well on the 88/89.
Plug and play? If you can get a set that's guaranteed....Other than that,expect to have to service it too...

Thanks for the reply. I read the thread you and waituntilthebeep had. WOW!!! I dont know if I can be that patient and am that resourceful. I am still trying to get to the carbs. I bought it with most of the fairing removed and the mechanic just gave up on it. It has been sitting for at least 6mos. The plugs I pulled were covered with soot, so running rich, he suggested cleaning the bowl and setting the float. Well like I said still looking at that situation. I put in fresh gas, changed the plugs and added 1/2 can of seafoam. Been fooling with the choke setting and idle. Still getting backfire....I appreciate the come back.

Mine would only run at 3k rpm with the choke when I got it.
I knew I had to pull the carbs.First time....I never said "you got to be kidding " so many times over the next 5 hours before on any job.
That was just to get them off the bike.
After 4 removals and put backs,it now takes just 2.5 hours to get them out.
So obviously if you can magically get them to work,,,try.
You can also open the drain screw(pain to get to between the radiators) and blow air into the crossover vent to clean the bowls out.
By the way.Popping in the carbs..A lean condition..plugged carb or vacuum leak..Don't get me started on the 7 vacuum lines that were bad on mine either.
That's a whole nother chapter.Still related to the carb tho.One of them is under the carb body.

By the way.I spent around a hundred bucks on stuff for the fuel problem on mine.About 3 months tinkering each weekend.That was a year and a half ago.Some 8k miles later,
It starts right up.Sometimes stumbles a bit without the choke for a minute or two,but by the time we get ready to roll,it's just fine.Its smooth with balance beads in the tires and has way more throttle than I should be using.I still get 32-38 mpg.
The battery tender jr.is a must.Keep the battery charged up eases the starting of the bike.A poor battery will crank it over but usually has a hard time firing it off.Been there too.
