taking the carbs off the bike

[maro]

Would someone be so kind as to give me some quick tips on getting my carbs off. I will be FINALLY cleaning them this week-end and will be taking them to do so. (my bike is parked in a garage far away from my house)

thanks

All a bit of a fiddle but you need to undo your carb to airbox clips and undo the airbox mountings and wiggle it backwards. till the boots slip off. Then undo your carb to head rubber clips (having disconnected the cables, pipes etc) and wiggle your carbs backwards. You need to lift your tank off as well. Once you've done it a few times it gets easier!

Like Hampshirehog says, bit of a fiddle but easy enough to remove them. Just a couple of little points to watch. Which model is the bike ?. Seem to recall on the 550 you have to remove the carbs first as the frame tubes prevent airbox removal first. I`m sure someone will correct me if I`m wrong !. On the 750 the airbox comes out first, removing from the right hand side is easiest if I recall. Make sure before removing the airbox that you have unclipped the various drain & vent hoses. Watch out for the wiring harness too. On my 750 the fixing brackets for the airbox end covers catch on the harness. When removing the carbs you may find you have to wiggle em a bit to get them clear of the clutch cable which drops between carbs 3 & 4. I find it easiest to remove the carbs toward the right hand side. After you`ve worked on the carbs, refit in reverse order. The trickiest bit is getting the airbox rubber sleeves back on. They harden up with age and can be a pain, especially nos. 2 & 3.

fuel tank off
remove side covers
remove airbox mount bolts
loosen all air side and engine side clamps
loosen throttle cables at handle bar open the twist grip and remove i cable end.

slide air box back as far as possible battery removed also maybe??
remove air box to carb boots
remove cable ends from carb
pull out and through the side

On my 81 650g, only needed to loosen the air plenum to airbox clamp and slide the plenum back towards rear to get enough clearance to remove carbs.

I would remove tank, loosen clamps on both airbox side, intake rubber flanges, and airbox to air plenum clamp. You will need to remove breather tube from top of motor to airbox. To get carbs out move rack of carbs up and down on airbox side while pulling the carbs from the rubber intake flanges. Usually one side will come first and then the other will sorta pop out, this means left to right. After you have separated the carbs from intake flanges, the carbs will simply separate from the airbox plenums. Next I twist the front side of carbs upward to remove choke and throttle cables from carbs. Now you should be able to slide carbs out one side or the other. Watch for the throttle cable clamp catching on the flanges as you remove. Not impossible but can be chore. Use a good quality screwdriver to remove clamps, the clamp screws are often rounded due to being removed before.

One other thing to note is the vent lines need to be pulled up from around the top of air plenum so that you can get enough clearance to move carb bank around. Just pull them up out of way.

If you will be taking carbs with you to clean, be aware that they will have gas in them that will leak out if they are turned upside down. May want to dump before transport or secure so they will not dump gas where you may not want it; car interior, etc.

Taking them out is easy, getting them back in is the fun. Just watch the clutch cable position and I find it easier to put intake side in first and then airbox . Use spray silicone one rubber flanges and airbox flanges. Have fun.

thanks waterman, for the specifics on the 81650 bike. I can do this, I can do this, I can do this.... my mantra.
