Title: Engine Backfires and Shuts Off
Post by double410 on 06/20/10 at 02:09:15

Hi: I just purchased a 2001 savage with 8473 miles. When going up a long steep uphill grade running the throttle almost open the bike will backfire and loose power sometimes shutting off. After setting a moment it will restart and run. It seems like there is a fuel issue. I checked the fuel pet-thingy and it appears the vacuum is opening it. Do think I could have a float not set correctly in the carburator. Where do you suggest I check next. It seems to run OK when the throttle is not held almost open. On the flat the bike runs OK up to 65 MPH with no issues riding double.
Any Suggestions?

Try it w/ the petcock on Prime.

And if that don't do it, check any fuel filter that mite be partially clogged.

I would not suspect the float level adjustment.

Long uphill climbs with the throttle wide open will get the vacuum down to nothing. Where a tiny leak in the vac hose will bite you in the ass. Check the vac hose for loose ends or dry cracks. Or just replace it.

Hi Everyone:
Thanks for the advise! I have been running the bike with the petcock on prime and my cutting out issue has been resolved. Woudn't you think if this is an issue with many of the bikes Suzuki would be on top of it and do a saftey recall and repair their problem? This is a safety issue when driving in traffic. Thank you for allowing me to join your web site. I enjoy reading the many comments.

Rubber hoses aging and cracking on bikes or cars is a normal "wear & tear" issue that should be checked/replaced as part of normal routine maintenance and that is our responsibility as owners/riders.
Safety ? yes ... but it is up to us to fix it

Do yourself a favor...if you haven't already replaced the vac line, buy a Raptor petcock and never have the problem again...

Remember to plug the vac port to the carb.

Replace your fuel and vacuum lines. The factory ones are thin, you should run reinforced fuel line. I always ran dirt bike tank vent line when i had the stock tank and fuel valve, doesn't age out like the stock vacuum line, and can be somewhat color matched to your bike color.

Every year I replace the vac line with a new piece of 1/4" black fuel hose from O'Reilly's regardless of the condition. It's cheap.

Or go into the Tech Ref sectiona and read the manual petcock conversion thread. ((Use the index sticky post at the top of the page)).

Cost me 23 cents to convert. Another $3 to replace the back plate (the vacuum inlet plate) with a flat stock piece of aluminum for a nicer look and easier tank removal. It's not quite as easy tank removal as the raptor , but it gives a little bit more reserve fuel than the raptor.
