Hi from reading the wiki stock Keihn carbs use jet size 60 for Pa50 and 78 for pa50ii
My stock Keihn carb has a 75 in it and it is the larger Venturi size of ~12mm not the smaller 10mm variant in the front pa50.
Not sure if I’ve damaged the size or the main jet from cleaning so wanted to be some sizes up and below what I’ve got now to see if there are any performance gains.
Currently bike is running rich / lots of blue smoke and bogging down past quarter to full throttle. Might be 4 stroking??
Idles fine but doesn’t like WOT.
Was I too vigorous with my cleaning or the jet and damaged it? Enlarged hole? I did put a bit of wire / inter dental brush cleaner down there to ensure there went any muck.
If I forced something down there would it possibly alter size?
