can you clean motorcycle carbs while still on bike gpz900a1?

Answer 1

What you are referring to is called an Italian carb job, it is only minimally effective and dangerous but here goes. Get the bike cruising at 1/2-2/3 throttle in top gear pull in the clutch and drop 2 gears then pop the clutch the result will feel as if you locked up your rear brakes and your engine will sound like it's going to blow, however do to the high vacuum sometimes this will suck all the debris out of your carbs. Only try this if you are an advanced rider.

Answer 2

If you are suffering the most likely causes of needing carbs cleaned, there is no way to do it on the bike. Most common problems are leaky float needles, and plugged pilot jets. If the bike has set for some time, plugged pilot jets are very common. They CAN NOT be blown clear, if they are filled with varnish, from sitting. They have very small holes, and the varnish gets very hard. The only way is with a #78 number drill (0.0165"). A jet cleaner wire will only bend DO NOT USE A LARGER BIT!!!!!!!!. With modern gasoline, we have found that if a bike sets for 6 months, it is a 50/50 chance it will start and run on all 4. If it sets for 12 months, it is 100% it will not. Another problem you may have, is the rubber seal washer in the petcock may dry out, and come apart, shedding tiny bits of rubber into the carbs, and sometimes keeping the auto fuel shut off from working. For the past years, we have averaged a "Sitter" a month, the most recent was a Kaw ZX600R, 1987, with 20k miles, The inside the carbs were brown from varnish, the seats full of tiny bits of rubber, and the rubber was stuck in the varnish in the fuel passages. It took several tries, and days, to get this one sorted out. And, as usual, at first, the more we worked on it, the worse it got. The varnish starts to dissolve, and runs down, plugs the pilots, and gums up the float needles. So, know what/where your problem is before attempting any repair, have prober tools, a couple cans good carb cleaner, and a lot of patience.

Answer 3

To really clean it right, it needs to come off. Seafoam is an additive that will do about as good as it gets with the carbs still on the bike

Answer 4

sorry old bean but the only way to do it is the right way. If you have a half decent tool kit and a reasonably logical brain it's a straightforward job to remove them give them a good clean and refit them. They will probably need balancing at a dealers after though. If you lay the bike up for winter it's best to drain them.

Answer 5

you could get the float chamber off with a short screwdriver an a lot of patience but better taken them out.be thankfull you dont have a v4 set up like a vfr.two mins to take the carbs out an two bloody hours to get them back in lol

Answer 6

use a pressure airline to blow the carbs clean, just attach the air line where your fuel line goes and let the air rip for a few seconds.

Answer 7

What do you mean by clean, what part(s) need cleaned?

You can drain the float bowls to remove any crud in them whilst still on the bike.

iirc removing them isn't terribly difficult, do you have the Kawasaki workshop manual?

Answer 8

No, I think you'd have to get off of the bike before you carried out any maintenance.

Answer 9

i ve had a few 900r blinding bikes but unfortunatly the answer is no. i know there a right pig to get the air box on and off but if your gonna do it, do it right!

Answer 10

There are additives on the market you simply add to the fuel tank and it cleans out the whole system.
