The best solution is to put a raptor petcock on it and save yourself a lot of trouble.

The tank was a two-day project already. If you haven't seen a full tank of gas reduced to thick black goo you haven't lived. I haven't figured out yet how I missed the petcock. I usually check them first.

The bike at least was stored indoors, so the engine didn't freeze or even get reluctant. I was very pleased at its condition. I have started bikes that sat much longer than this one did.

I probably won't give this petcock more than today. An aftermarket replacement is only about $10. Has anyone tried one of the cheap aftermarket petcocks? I usually avoid cheap aftermarket parts, but a petcock is just a valve. There is no adjustment. If it doesn't leak, it either works or doesn't.

Do you have a link for that one, Tom? "Raptor petcock" gets more than 500 results on Ebay. Several models of petcock, too.

And it's best not to use an inline filter, they can be come air bound or hold water,slowing or stopping fuel flow. the bike has two filters already, the petcock screen and a small screen just above the float valve seat in the carb ,you should check that one also if the bike sat with fuel that long. the petcock comes apart from the front ,the metal piece that labels the position can be gently pried out on both sides .

If you don't see the Yamaha brand name and the white box....it is most likely a cheap Chinese copy.

I got most of the petcock apart, Batman. I just can't figure out if the white plastic selector plate pushes out from the back. Since it is frozen with old fuel, I can't wiggle it to see if that is possible.

The petcock I have looks rebuildable. The rubber parts are in good condition. If the Yamabond loosens that plastic plate so it turns I'll put this one back together and use it.

The parts on this bike were essentially new when the bike was parked. It only had 1,200 original miles when it crashed. Everything alse was rebuildable/reusable (except the front end), until I hit the petcock. I haven't given up on it, but if replacements are cheap my level of effort becomes a bit less focused.

As others have mentioned, in inline filter can be a big problem - especially  if you buy a Chinese copy with the small outlet.  If you need to use a 1/4"  fuel hose on the petcock....then you install a 1/4" plastic inline fuel filter - the fittings on the filter are made of thick plastic and the inlet/outlet hole are tiny.  The 1/4" fuel line and filter can likely flow enough fuel for the Savage - but what happens is that when you turn on the petcock and the fuel flows down while the air is trying to come out of the filter......and air bubble can get trapped in the small filter openings and cause an "air lock" that prevents the fuel from flowing through the filter.

The petcock has filters on the inlet tubes.....the carb has a filter just above the needle/seat - you really don't need an additional filter inline. (Provided you have done a good job cleaning out your tank).

The stock petcock can be a problem - the ethanol fuel either causes the diaphragm to deteriorate and get leaky (which causes too much fuel in the engine and can also flood the crankcase and/or airbox with fuel) - or the diaphragm can get stiff and the petcock doesn't work properly.  When the diaphragm gets stiff the fuel flow becomes intermittent and the flow stops when the engine is under load and has low engine vacuum - so the bike can run well until you get up to highway speeds - folks misinterpret the symptoms and start looking everywhere but the petcock.

These folks have given you very good advice that comes from years of combined Savage experience - you really should choose to trust them and not use the stock petcock (especially with the original rubber parts).  And if/when you buy a replacement petcock - you should spend $30 and get a genuine Yamaha Raptor petcock.

It is not always "Our way of the Highway" - but it can be "Our way or a long walk Home"
