Discussion about the right valve setting dont solve agonda 1 problem about his hot pipe
He wrote that all has checked, but fit reduktion buffles.
I guess this will show a fault in ignition timing for one cylinder.
Most K2F have a diffent timing with 1 till 4 degrees by the camring, this will be in addition to the crank showing 2 till 8 degrees.
So it is strongly recommented to set the ignition by a strobe and check both cylinders.
As l build up my scrambler with a megacycle cam and open high level pipes form Armours, I also ordered the recomented silencers.
For testing in the garden I had fit only the pipes, and it was gread in power the engine runs phantastic, but horrible loud.
Than I fit the silences and it was all over with good running, the bike drive me crasy.
Than l odered taiwan silencers, straight through ones, a look a like silcencer with a little rockwool inside......blow off in few seconds
I spend them a new blanket isulator and now a dream.
This special cam need the open pipe with reduce in diameter.
