Bike seems to bog down
04/01/14 at 17:56:45

I have a '86 Savage with a '05 engine. I'm using my carburetor from the '86. the bike seems to run fine and idle fine but when riding it runs fine until I get to 1/3 or 1/2 throttle and above then the bike just bogs down. I bought a jet kit which came with a 152.5, 150, 147.5 main jet and the pilot jet. I've tried every combination I can think of with no difference. Is there something that you guys know of that can help me to correct this issue. I have completely taken the carb apart and cleaned everything. Also I am at 4600 feet above sea level. in Northern Cali. Thanks in advance.

Found on another thread it may be because of the different timing of the spark from an 86 CDI to the '05 engine. It that thread the original poster swapped out the flywheel from the original engine to the new one so I'm gonna try that.

Since you are using the '86 carb, what groove is the needle clip set on ?

My Savage stalled recently after a dynamic acceleration, and barely started again after that - it turned out the vacuum line was barely hanging to the petcock connector, so I guess it wasn't allowing a normal fuel flow. It was OK on the prime setting, and since I fixed the connection everything works.

Earlier I had some flakes of paint from the tank blocking the petcock, which caused similar issues (stalling as soon as the engine sucked up all the fuel). So now this is the first place I look

BTW I guess if the engine won't get enough fuel due to petcock or fuel line problems it will backfire more, so that's one way to diagnose it.

Well, "barely hanging" will certainly do the trick on fuel flow.

I did buy a jet kit and tried each main jet with no difference. As for the petcock I'm running the Raptor petcock.

The stock exhaust is your bottle neck. I believe that is likely why you are not seeing a difference when you try different jets and yet don't see a difference in performance.
