First Problems
04/22/07 at 15:41:08

Hello,

I have an 05 S40 with 6400 miles, I have put about 3000 since purchasing last September. I started out today, just briefly with the choke out (it was almost 80 degrees). Within a mile when opening it up in 3rd it began to stumble and lose power when entering onramp of highway, and then had trouble starting it. After pushing it back up the ramp, I was able to start the bike and then headed toward home in which the same stumbing and stalling occurred at around 35 MPH. I then repeated the process until getting the bike home. I have been riding the bike all winter, so its not like it has been sitting idle (1 week in this case). Any ideas, as sad to say I am not up to speed on the Savage mechanically yet.

Rich

You could just perform the petc0ck conversion posted in the tech section and be done with it, but if it runs fine on PRI, you'll know the diaphram/vacuum lines are the culprit.

You had sufficient gas. Petc0ck was in the correct position. Correct so far? Have you done anything to the bike lately? Any tinkering at all?

Might be an early failure of the timing chain tensioner, it sounds like it runs the same way mine did. It still ran (barely) when I trucked it home. Luckily the tensioner plunger was still hung in the tensioner body, but the spring had popped out.

If your gas is good to go, but a sudden power loss appears, I think it might be mechanically related.

Does the power loss seem consistant ???

While all of these are good suggestions, you might want to start with the simplest things first (filler up). Make sure the enrichener (choke) is off and correctly adjusted when the engine is warmed up. Then try with the petcock in pri position. etc. etc. Also anything you have done recently that might have knocked a wire or hose loose would be good areas for a visual/tactile inspection.

It's not real clear that you put the "choke" back in after starting before this problem occurred. This engine will die in warm weather if the "choke" is out.

Another way of putting this is that you won't fix an out of fuel condition by tearing apart the engine.

I've read somehwere that there are better ones to hold the hose on but these ones a) are better than nothing b) work for me
