Coolant in the Carbs

After my crashed last week, I noticed some cooant spilled out the top of the resevoir. I suspect it leaked into my airbox and into my carbs. But I can't seem to fix the carbs. The butterfly valves continue to stick. The rear butterfly wont even open. I cleaned the carbs out, but have had no luck. Could anything else cause sticky bullterflies? Anything electrical?

The coolant bottle shouldn't be connected into the airbox at all AFAIK.

If your throttle won't open the butterfly valves it's mechanical. Note that the Black Diaphram that comes down to cover most of the inlet is raised and lowered by pressure difference when the engine is running and are not affected at all by opening the throttle when the engine is stopped. The brass butterfly valves are directly connected to the throttle.

Disconnect the throttle cables and see if you can turn the part the cables were connected to by hand to see if it's throttle cables / throttle assembly or the carbs themselves.

Edit: The 2 brass butterfly valves should open at the same rate for the front & rear cylinder as they are connected to each other.

I'm assuming you're on a '99-'02 bike.

Ok mabe I didnt mean butterfly valves, i mean the grey/black diaphram thingy above the brass buttfly does not move. The coolant resivoir cap came off in the crash, and spilled into the airbox. That is how it got there, i know they arent connected....normally.

I think when cleaning i may have slighly deformed the rubber diaphram, would that cause the problem?

Do you mean the black rubber items that control the vacuum slides that pull the needles back?

If so then coolant will probably have killed them. Then again, they do get weak with old age. I just replaced the ones on my bike and gained several horse power!

yea those black rubber cone things. How much did each one of yours cost? I looked it up online, and couldnt believe my eyes....25 quid for a set. Could this be right.

if you can get them for 28 quid a set then bite their arm off. i think i paid closer to 40 quid!

I could buy a whole low milage set of carbs off of fleabay for that price.

but you won;t know their history. they could be okay but the rubbers could be tired even if not perished. at least it will get you running again

True. But, we ride. Risk is what we do.
