How full is the tank? How steep was the off ramp? Was it fine after you got off the ramp and were back on level roads?

Welcome Fry!!! I've never owned a brand new bike(a lot of basket cases and well-broken-in scoots though) so this is just my thoughts,take with a grain of salt. I'm thinking with only 2000 miles you may be pushing it a little. Your manual should give you break-in speeds for certain milage readings and I'd go by them.

I commute 45 miles each way to work(1996 Savage w/11,800+ miles) and I run 70-75mph for 20 miles on the interstate with no problem and have throttle to spare if needed. Back when we had the 105*F+ temps the scoot ran a little hotter than normal but I never had it die on me.

As an after thought......at 2000 miles it may be time for some adjustments and service. Have you changed your oil yet?

Good luck and keep us in the loop!

A vac petcock on a Savage has one noted strange quirk, at full running speed the vac level in the engine decreases slightly which partially decreases the fuel feed from the stock vac petcock.  This can lead to a listed & known symptom of stock vac petcock malfunction (fuel starvation) which is exactly what he described in his first post.

He can do the test set up, make a high speed run, report the results and then get more "help" from there.

And you do know that vac lines can fail at any time, right?   Verslagen replaces his vac line yearly as a matter of rote.   If he tests "vac petcock system deficient" then I am sure someone will suggest replacing his vac line.

Key thing when a new person posts with a situation is to FIND OUT WHAT HIS SITUATION REALLY IS.  The standard tests in Tech Section are designed to do this.

If anyone posts with a fuel related issue, to remove over half the of "unknown" from the situation use the http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1 test.   Do it first thing, right off the bat, make the poster reply that he did the test and get him to tell us what he found out.

This will tell you instantly what he understands about the bike and what he doesn't understand.   It also cuts out over half the fail modes instantly (no matter which half, half are GONE).  Then you focus on what is left.

At high rpm for 30 miles with lower vacuum and a fresh, stiff diaphragm spring, you probably just emptied the carb bowl. Perform the test, but it might be difficult to duplicate the symptoms. If it does it again, you can always try switching to reserve to see it that fixes it.

When I raised my idle speed mine stopped doin that.

The vac  system should (or may I say it must) work even if one's emptying his fuel bowl at top speed.

OK, right, the vacuum decreases the more throttle you give.
But it should at least be enough even if you go on max speed all the way.

I found out (and some others here around) that not only the vac tube sometimes plays tricks on you, also the rubber flange between carb and head (exactly the two screws which loosened), one should have a close look if that four little screws holding the diaphragm case on the petcock are tightened well.
On a newer bike they should, elder ones may need some little service there. Cause may be the paper sealing and the diaphragm shrinking with time.

hehe

so last night... ran 60 - 70 for about 20 miles.. engine began to cut out... swiched to prime (I can do that blind.. I forget reserve) ... bike only got down to 50 before comming back to life....


Its all good.. my new Raptor petcock is on the dresser awaiting install this weekend. It just got here 3 days ago.

PS: dern it.. jut realized I refilled the tank this morning to get to work.. now I have a bunch of gas to drain, saturday!
