SuzukiSavage.com - Broken diafraghm?

Thomas Högberg Junior Member Offline SuzukiSavage.com Rocks! Posts: 61 Vårgårda, Sweden Gender:	Broken diafraghm? 05/24/14 at 10:24:30 Hi have an savage -97 K&N panelfilter, 152,5 main and 50 pilot. Dyna muffler Runs good on idle and on small turn of the trottle, but no strength and will not accelerate as it should when I use more trottle. Carb is cleaned, spacer replaced with 2 thinner, half the height. Could it be a broken diafragm? Thomas

had the same problem when i bought it a few months ago, making a bobber out of it and done some improvements during this time, cam chain adjuster and cleaning the carb as a mentioned before.

the main in the carb was 125 or 135, hard to read.. so I was not expecting the same now with 152,5 Angry

Thanks for the input

You need to go in and clean again...

Love the thread title... Grin

As I have modified the bike to a bobber, it has not been on the road since I cleaned the carb, 2-3 months
Seems like it does not stick..

Beeing from Sweden, english is not my native tounge... but now I can see that my thread title can be misunderstood Grin

I wouldnt go chasing an electrical issue just yet. It sounds like a carburetor thing,,
I would probably pull the air tube off the carb so I could see the slide, get a mirror & watch it. If its not going up, maybe you did bust the rubber, or maybe didnt get it installed right, or maybe left fingerprints on the slide & its sticking. Its gotta be clean & dry, no oil, not even fingerprints,,

Reply #8 - 05/24/14 at 20:56:24 If you had the slide/diaphragm out recently, then you should pull it out again and check to see if the edge of the diaphragm is pinched and/or out of the groove of the carb body, which would allow an air leak, and that would prevent it from operating correctly...thus NO-GO when you crank the throttle. Trust me; I've done it before.

Trust me; I've done it before.

Pulled it out again, found no marks that indicate pinching, mounted correct in the groove also.
The lid seems straight and should make a good seal.

I changed the petcock to a raptor earlier and plugged the carb, can it be an issue?

Is there a way to check if the slide lifts ok when the carb is off the bike?

Just so you know, I bought the bike a couple of months ago and it had this problem.
Gambled and thouht it would help to clean the carb change the jets, airfilter and fresh gasoline...
