Petcock war again, I guess.
Everyone agrees that the stock vacuum actuated petcock fails and causes trouble for the owner.
Some (including me) say jest yank that durn stock petcock unit off and bounce it off the wall a few times in revenge for all the BS it caused you.
Others jest
love the little trouble prone vacuum sucking gas bleeding not reliably opening little thing, and they want you to spend time, $$ and effort to troubleshoot it and try to repair it.
The reason that they give for this is "gasoline in the oil" which does happen when a carburetor float malfunctions. Funny thing, gas in the oil seems to happen more often with the stock petcock than it does with the Raptor replacement.
(why? I dunno -- don't ask me to explain the 1,001 ways a failed vac petcock can make your bike run rich -- and then run some of that liquid gas down the vac line to the manifold, then past the piston down into the sump)
Now, if you go with the repair it folks, you will get another chance or two later on to reconsider and go with the Raptor replacment folks -- 'cause guess what happens to your rebuilt/repaired vac petcock given enough time and miles .....
Guess which one is cheaper, a repair kit or a Raptor replacement ....
And as an added benefit, when you go raptor you can take your gas tank off without having a big hassle.
