brand new petcock issue
06/25/10 at 23:18:36

so i recently just purchased a 95 savage through a private sale. initially it was having sputtering and dying issues, bike hadnt been ridden in a year. so the previous owner yanked the carb and cleaned it, flushed out the tank and had fresh gas in it, and also replace the petcock with a brand new OEM petcock. when i rode it home it started to sputter again so i switched it to prime. ran like a dream after that!

ive been digging around the forum for the petcock fix, but what would be the issue if you already replaced it. i wanted to go to the raptor but i figure this guy just replaced it with an OEM one, i might as well get his money's worth out of it. the only thing i can think of is the vacumm line is bad. can anyone think of anything else that would be the issue

I just went through petcock issues. I rebuilt the dam thing and did some carb work, all to no avail. I pulled and plugged the vacuum line and run it on prime. Runs great once warmed up. I do still have idle issues but I can deal with that. I have to turn the throttle stop screw about 1 1/2 turns in when cold. Once it warms all the way up, I put screw back where it was and ride for hours with no problems. I never used to have to do that so there's still a problem somewhere but it's not the petcock. Like I found out, once rebuilt doesn't mean it's working right.

I am forever tweaking the idle . B4 its warmed up, it needs a higher setting, to get it off the choke after 3 or 4 minutes & it not be just too low RPM for the oil pressure. Once it warms up, I lower the idle back down so its not racing. Takes about 15 or 20 minutes of riding b4 its totally smoothed out. I dont mind it one bit, its just me & my engine, its not a carb problem, its just the way that engine works, IMO.

The petcock on the W is a vac iperated unit,. I opened it up, just to have a,ook. Kinda reminded me of the stuff in a weedeater/chainsaw carb, w/ little flaps cut & just waiting for a tiny piece of anything to get in there & mess things up. If I was working on one, Id sure want no lint or anything around, they look pretty persnickety.

If any valves were leaking slightly, it would lower compression slightly, causing a drop in HP, and a drop in vacuum, but could still run quite good,....or what you mite think is good. But that would be a last resort only if no other problem was found..

Part # says FCK-5 GS1150 $23.00. It didn't fix my problem so I'm running it now on prime, with the vacuum line plugged and the vacuum port capped. If I had it to do again I would just get the Raptor and be done with it. Also about $23.00.
