Can the Pamco e-advancer be causing random misfires?

[Lusodub]

Hi,

Can the Pamco e-advancer be causing random misfires?

My bike has a sligh uneven idle problem..idles at 900rpm and at 1100 rpm randomly.
On acceleration, the bike randomly misfires... And therefore The bike is impossible to run correctly.

The first 100 meters the bike runs well...

My diaphragm are not in good shape...

Timing is good
Cam chain is good
Battery and pma good
Carb are really clean all the seals are changed except the t carb connector.
Carbs are synced and tuned.
Carb boot new and not air leak..




Thanks for your help... Im having a real hard time finding a solution.

Hi,

a solution

check throttle shaft seals, choke plunger seals.

Thx for the answer!

Throttle seals are changed!
Will do the choke plunger.

The diaphragms seem to work (passed slide test) even if they are in bad shape... I think i will still change them.. Im running out of options..

Thx

Another question? What would be the symptoms of a bad choke plunger or seal?

Thx
