Bike will hardly reach 70mph !! it was over 110mph without baffles..[/align][/align]I tried to restrict main jet -(not knowing what the stock sizes is) I fitted it with 160 and engine will go trough full range of RPM but it is still weak compare to former setup..[/align][/align]Any suggestionwill bemuch appreciated !![/align][/align]Thank you[/align][/align]Peter[/align]

You might condsider pulling the f'in baffles out. Now you see what a stock bike is like and why a stage 1 upgrade is needed.

 

I don't believe the sampsons are designed to have baffles in them.
I'd install different mufflers.

 

You could email Samson product support, tell them what you're doing and ask them what jets they recommend.

 

I used HP Power Plus baffles inthe Samson fish tails on my Road King with excellent results. Later when I replaced the cracked fistails I welded a 3/8" washer on top of a 5/16" bolt and installed them about 8" back from the end. Power was the same, on a dyno, but louder than the baffles. I still have the baffles, if you are interested in themPM me.

I dont know what elevation your at in Slovakia but I would think the 48 pilot and 190 main are to rich. try a 45 180 combo, start with the mixture screw 1 7/8 turn out.
