Title: Bucks and dies after raptor intsall
Post by fireproof4891 on 09/06/18 at 11:35:51

Hello all! New here and I need some help. I have a 2002 savage with 15,600 miles on it. Rode fine for a while after I got it but then started having issues. I was new to bikes so I came here and got some ideas and advise. I cleaned the carb using the guide on here somewhere. When I went to change the oil, it was full of gas. I mean like mostly gas and the air box and air filter was soaked. To I cleaned it all up and put fresh oil, a new oil golfer, and a new filter in (the right way) and it worked well for a few weeks. Then it started sputtering and dying while going down the road even with a full tank and I read that is usually caused by a bad petcock. So I replaced the original with a raptor an following the guide also on here and capped the vacuum port on the carb, filled up with fresh gas and it started right up without issue. But when I tried to ride it as soon as I put it in gear it started bucking and died before I made it 100 feet. I ended up having to push it back home. Could there be a step that I missed or something I overlooked that may be causing these issues? Everything I have seen on here says that must issues with the savage can be fixed with fresh oil, a new tank of gas and installing the raptor. I’m at a loss with this. I’m not a mechanic by any means but I know my way around technical manuals and youtube is my best friend when researching problems. And help or advice would be greatly appreciated.

Unrelated, but, important..
Have you dealt with the cam chain?

Did you get a Real Raptor Petcock or a twelve dollar Chinese knockoff?
Did you add a fuel filter?
Plug the vacuum lines?

yeah what jog said... after that next most common is putting the jets in the wrong hole.

No I haven’t done anything th the cam chain. I got the real petcock and I plugged the vacuum line on the carb directly. I didn’t add a fuel filter. I used one in the past but it seemed like the filter was slowing down the fuel flow so I took it off. And I don’t think I put the jets in wrong. The bike sat for a while with the previous owner so I bought a replacement set and changed them one at a time so I wouldn’t get anything confused. But after I did the jet replacement I didn’t have any issues for a while.

You removed the plastic tubes from the Petcock filters.
You have the Petcock lever pointed the right way.

And I don’t think I put the jets in wrong.
But, you might have..

Before you tear into anything
Put a piece of tubing on the carburetor bowl nipple and drain it into something.
See if it runs or stops,
Just a cup held under will work, tubing isn't necessary..
Just prove you have fuel into the carburetor first, and that it's a steady supply.

I did everything according to the guide I found on here. And if I did put the jets in wrong how long would it take to show? I rode it for weeks after the jet replacement. Do I need to turn the bike on with the carb float bowl screw open?

No. Do not try to start the bike or even turn on the ignition while the float bowl drain is open. That's how fires start. I would try to catch the fuel coming out the drain. You can confirm flow and check for contamination at the same time.

Ok I will try that as soon as I can. Does the fuel coming from the float bowl drain correlate to the speed of the fuel coming from the petcock?

All fuel flows through the petcock. So sort of. The petcock should be able to flow more fuel than the carb needs. You could also pull the fuel line to see how much the petcock can flow. But the idea of using the catb drain is to be sure the carb is also flowing.

Is the inside of your tank clean? Is it possible you are picking up crud from there?

My bike just after I bought it would not start. The problem was a loose
spark plug in the head. Someone had not tightened it properly
Just a thought

It starts up at first no problem. I even let it start and idle for a few minutes to make sure that it would get warm without issue. It’s when i put it in gear and start moving that the problem arises. And once it dies then it won’t start back up. I’m not picking up crud from the tank unless it’s small enough to pass through the new petcock filter screen.

It sounds like the main/needle jet is clogged.
but i'd check the screen over the float valve too.

You didn't say you changed the oil again, AFTER replacing the petcock ,have you checked your oil level lately ?

And if I did put the jets in wrong how long would it take to show? I rode it for weeks after the jet replacement.

Usually, since the jets are the metering devices that create the fuel/air mixture that allows the engine to run, should a jet be clogged or grossly missized, it only requires about a hundred miles of riding for the engine to start to misbehave, much like running out of gas.

Does it run well - until you put it in gear?

Does it start again if you put it in neutral?

Could you be having a problem with the side stand safety switch?

I think Dave's onto something.

And don't let it idle sitting on the sidestand.

Yes , think Dave's right , side stand switch . I've had it be just the springs ,the J bends in the ends get stretched open a bit. and don't pull the stand all the way in, when it's up . the minute you put the bike in gear it dies.
