A skunk in the works

[chuck hahn]

probably ran down the vacuum tube and NOT thru the carbs...as thats the usual route if the floats are seating the needles correctly.

No big surprise,the rebuilt petcock dumped 1/2 a tank of gas into the engine caseYes right though brand new neddles and seats in the carbs

It doesn't sound as if they are sealing very well.

Have you tried running it set to prime - with and without the vacuum line attached? Blocked when not attached of course...

No such luck,the 750 petcock seems to do exactly the same thing as to 1000 oneBack to waiting

Well I managed to get the 83 750 petcock hooked up wit a bit more fuel line than I would like but on just idling it's already way better.Off for a ride!
Still going to get the rebuild kit for the 1000 petcock but I just want to enjoy the riding weather

Hi SVSooke,

I just PM'd you about the OEM petcock.

Replied to.

Hi SVSooke,

I know that people on here have had less than sterling results with rebuild kits, but I used a kit on mine years ago and it is still working fine.

Thanks that is encouraging.It feels like the right decision.

With some discussion it's been decided to get this http://www.ebay.ca/itm/291675152778?...%3AMEBIDX%3AIT petcock rebuild kit.Yes I can see the going.I just want to keep a stock petcock and $300+ is just to much to spend.Don't really what to do the futzing around to put a 750/850 one in either.With every thing on mine in pretty good shape this should work.Going to take special care on the O ring seat.

Air is also choking off the fuel at low RPM's and that disconnecting the vacuum line to synch the carbs made it run nice.Either way it looks like the petcock is the problem.

Condensation will accumulate in the vacuum line. Don't mistake that for back flowing of fuel. My old mercury sync gauge used clear tubes and quite a lot of condensation would be visible in those tubes.

Still running poorlyBut did some playing with the petcock while riding,as soon as I switched to prime it would be OK,back to on and problems.Looking at the clear vacuum I just put in you can clearly see a gas mist going though it. Guess my original assessment that the petcock was toast was right.Going to see if and how much the local dealer can get the 44300-44011 for.Canada's MC Supperstore lists them as available for $199 but when you try to add it to the cart I get an error message Will see how much for a 44300-45011 750/850 petcock to.The other idea is to go for a manual $30 USD petcock from Parts N' More with a $8.50 USD adapter plate and $4 USD 90 degree turnout for the outlet it would be cheaper.The downside is I've got used to not worrying about turning the fuel off,decisions decisions.

Went out again in the afternoon for a bit more shakedown.


For a town by the ocean it is surprisingly hard to find a spot to get a nice pic with it Had some issues now resolved(I hope).
