GT750 carburettor refit sequence

Postby crazy4557 » Wed May 27, 2015 9:02 pm

It's a really tight fit to get these out so what's the procedure for refitting please? I assume there is an easy route so if you can let me know I'd be very grateful.

Not sure on other bikes but on my 750J I find it easier to fit the carbs loose then fit the airbox after, that way there is a bit of extra "wiggle room" before everything is tightened up. It does get easier with practice.

Whatever sequence, use a hair dryer to warm the rubbers and smear a very light coat of oil on the rims of the carb inlet/outlets. It makes life so much easier. Kev

If you are talking about the later models, and the boots are not new, then I sometimes resort to using a ratchet strap/tie down and a block of wood. Grease the inlets of the warmed boots, loop the ratcheting tie down strap around the barrels and across a small block of wood on the inlet bells of the carburettor rack, and then just ratchet them home gently till they seat. Easy peasy ! 8-)

What about trying to refit the compete airbox. What's the proper way when the carbs are already fitted?

Me, I spray a little silicone on my finger tips and use that just inside the engine rubbers and also warm them first with a heat gun (care! if you smell burning rubber...).
That helps a lot even with built-up carb sets (all mine are).
Fitting the airbox. The best discovery I made other than to use the heat gun is this. The metal bands used to secure the airbox onto the carbs? loosen them off and slide them rearwards. Now you have soft rubbers without a metal skeleton which previously stopped them flexing far. The whole box goes on easily. If you've repainted your frame and keen not to scratch it, put some paper masking tape on the top right side rail. The airbox is so tight it does scrape there, but the tape will protect it and peels off easily later.
Never feel reluctant to take your 750 carbs off ever again, it needn't be torture!
Mike
ps: its a bit fiddly to push the clamp rings on the airbox rubbers back over the carbs, hence why I suggested loosening them. A poke around with thin, long, plain blade screwdrivers does the trick.

My carb rubbers were rock hard when I first tried to get them back on and it was impossible. Then I got Baz's dvd and soaked the rubbers in acetone for a bit and they go lovely and soft and it becomes easy.
