Reply #15 - 08/06/13 at 13:00:07 Well, I just got my Raptor 660 Petcock today (OEM part# 5LP-24500-01) and installed it. At first I forgot to cover the vacuum intake port and thought "oh no" but once I figured that out PROBLEM SOLVED! Thanks again for everyone's help and advise. Total cost $29.41.

All years of Raptor 660 petcocks are the same... just make sure it's for a 660... not a 350 or 250... and buy factory... not a Chinese knock-off...

I bought a Chinese , shipped from China and it works. The outlet is a bit smaller but a fresh new hose fitting the smaller size will squeeze on the bigger size.

Hello again fellow Savageers! Well fortunately for me the new petcock only cost me $29.41 because that did not fix my problem. It worked fine after a few test runs but this weekend it bogged out on me again after reaching 75-80 mph. So in a desperate attempt to try and resolve the issue without taking it to a mechanic, I decided to put back the stock petcock and just try and adjust the idle mixer screw and the idle speed screw (because it was popping like crazy anyway) and viola! Problem solved (so far) and the popping is gone too. Was this irony or could that have been my problem? (Popping has subsided 90%)

Been super busy. Yes, I blocked the vacuum line. Ever since I adjusted the idle mixer screw and the idle speed screw I have had no issues.

Adjusting the idle mixture screw really should have no affect on the ability of the engine to run at high speed. When the throttle is opened beyond a 1/4 turn, the carb butterfly is in a place that no longer pulls the fuel from the Pilot Circuit.....and the Needle jet and Main jet start supplying the fuel.

Glad it works for you now......but I have no idea why.

You really should put the Raptor back on permanently.....so you can avoid the future failure of the stock petcock.

That is one of the things that can cause it and popping the fuel cap off to see if that helps is always worth trying. It does not seem to be a problem on the Savage most of the time, as the cap and gasket is so leaky on our bikes that the fuel tank usually does not have a vacuum problem.
