jetting a 400 stroker motor


Polish

Recommended Posts

I have a 400 stroker

28mm pwk 160 main jet 4th clip

Sea Level

 

 

1/4 to 1/2 throttle is perfect!....so I assume low end jet is fine

 

when I hit top end it dies.....almost like it is flooding out!

 

Up or down on the Main?

 

Any body have this set-up?

 

I bought the carbs direct from Sudco.......and told the tech what motor mods..and this is what they sent me........and top end runs like CRAP!

 

Any carb Mechanics out there? :cheers:

try a 150 main and see how it acts.

 

i run a 140 main at 900ft elevation with 34

but your in compton,"city of compton" lol so probably around sea level

so try a 150 and do a plug chop.
