petcock (Read 94 times)

Bubba Serious Thumper Offline SuzukiSavage.com Rocks! Posts: 956 Denver, CO Gender:	petcock 05/25/10 at 12:00:39 Could someone let me know what is the purpose of a vacuum activated petcock? Why wouldn't I want to replace it with a Raptor? I'm suspecting mine but haven't figured out the how/why of using a vacuum to pull the fuel. Any thoughts? Thanks

Problem is,.. when it fails,... it floods fuel into your crankcase... ... How's that for stupid?... Get a Raptor... ... Raptor info here...... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429

I remember reading on here somewhere that it can also be cold sensitive also...seems like whenever it drops to around 45 or below my bike runs like dog doo unless I crank the idle way up and set it on PRI. So is it a given that you'll get fuel in the crankcase if you forget to shut it off? Thanks guys

Not at all,... it will only happen if the float sticks at the same time... I've never had it happen in over 25 years of riding, and I never shut mine off unless I'm pullin' the tank...
