we rejetted buddys 07 750 . put all back on,broke clamp(fixed now) checked for leakes(put hand over snork) died quickly.put in pond for further test .died in water after awhile , bumped the starter to see if locked up , cranked right back up .noticed steam coming out of tailpipe. keep in mind he has the tailpipe snorked so outlet was never under water.got water in oil just enough to give it a haze. dont look like its coming in through the carbs ,wouldnt it lock up one of the cylinders?? and not crank back up. im needing ideas on what to check ,like a list or something. seems like water is only on the exhaust side , does that make any sense? would a hole in the exhaust system cause this?

A hole could cause this, could be a blown head gasket too. check the rad and see if you are losing water

also make sure you have no cracks or melted holes on the crankcase vent tube.

Is water getting in the air box? if so you need to check the crank vent, lilke Phreebsd said, and also the little "duck bill" drain on the box... need to seal it up really good

duck bill is siliconed up , no water is coming in the airbox,we will check the crank vent tube ,thats a possibility, I chatted with hondarecoveryman last night and after explaining further we've decided its possibly coming in from hole in the exhaust, but im gonna check the tube and the exhaust before we get to the pond.THANKS

Also check all your exhaust connections. The Y might be cracked or leaking. Put her under clear water and get someone to hold their hand partly over the exhaust snorkle. That should build enough pressure to see a leak along the runs or gaskets.

put it in the pond slowly this time (about an inch at a time ,keep in mind we let it set for a few minutes before going any further in) covered the exhaust -ran good ,covered the carbs-ran good, got to the bottom of the rubber things on top of the carbs -started hesitating and finally died. so back to taking off the airbox looks like we got it narrowed down to the rubbers or somewhere within a 1 1/2 inchesof it. gonna reclean them put new clamps on ,check for pin holes .anything else around that area that we might check on? open to all suggestions .

Same thing happened to a friend of mine's Brute. He had a hairline split in one of those grommets. It was a couple of weeks of frustration until the problem was found.

Nothing causes more trouble than a hole in your rubber.....I hate it when that happens.

Yup, hard to see but the clamps can cut/split the rubber. Done it on both of mine. Cheap to fix, but hard not to overtighted those.
