Hello All:

Recently purchased an 88 CBR600F and need to clean the carbs. I read the How-to and am having difficulty removing the carbs as aunit. I have loosen the clamps on all of therubber isolator bands, but I guess the rubber has basically become bonded to the carbs over time (as well as the engine port side). I've tried rocking back-and-forth and side-to-sidebut they're not letting go. I've also tried blowing a bit of hot air from a heat gun to try and lessen the adhesion, but man are they stuck on good.

Is there something I'm missing? Is there a trick or method to getting the bands to release easily?

Thanks,
Jaime

 

pry all the way around the rubber from the carb. that should get it off if the rubber is stuck on. once carb set is removed, put cloth down into intake tract to keep any debris from falling in. if rubber carb connector is tweaked, should probably get a new set. once the clamps come loose, there isn't any thing left to remove aside from push/pull cable and fuel line.

 

I was thinking about trying to get a rad like hose-tool in there to try and break the seal but was worried about destroying them, as well as the limited access to manipulate it all away around the carbs. I shall perservere now that I know that I'm not overlooking something .

Thanks,

 

If you have a torch or even a hair dryer try getting them hot.

It gets a lot easier after they've been through a few heat cycles and you've had the carbs on and off a few times.

 

i need new manifolds soon but i used pb blaster to put them on and take them off. they get very stiff. you have to thing 16-20yr old bike

 

Well, I've got penetrating oil - didn't think of it for a rubber-to-aluminum non bolt application but I'll give it a try.Try a few more heat cycles with the hot air gunas well.

I'll have to check out walmart for thepb blaster stuff (not sure if it's available here in ontario,canada).

thanks,

 

Success - some penetrating oil, heat gun and a bit of patience rocking it back-and-forth. Hopefully tomorrow I'll get a chance to wash down the carb exteriors with some degreaser.

Thanks
