Is a raptor petcock necessarily a genuine Yamaha part? Or are there knockoffs? I bought one online at eBay. The filter screens were very loose and one of the screens would not stay in. I stupidly tried to glue it in with permatex gas resistant sealer. (I think I confessed to that in a previous post) The on-off-reserve valve seemed really stiff and cheesy. An hour ago I pulled the screens out as part of a tank cleaning and chucked them. I had an inline filter to replace them. When I put the line to the carb back on and tried to tighten the hose clamp, the brass fitting pulled out of the petcock. I have looked at a couple of sites and they say raptor petcock, but do not indicate it's a genuine Yamaha part. Perhaps I should just go to the Yamaha dealer. I might go back to the stock petcock.
Also whoever suggested safety wiring on the nipple to the vacuum port you don't need with the Raptor, thanks. Very good idea. I've been worried about that popping off.
