So I finished my first build in spring and been riding all summer. After a lot of carb work details to follow my bikes starts and rides smooth until mid to full throttle on each gear. Where it sounds like choking out. Here's what I have done.
77 xs650 stock 38 carbs w new mikes XS rebuild kit including stock jets 135 mj 27.5 PJ and new needle (now at position2)
Chopped stock pipes w baffles
Oversized pods
I did late spring check cam chain adjuster valve lash and check timing regularly on my pamco.
So after I cleaned and installed new jets I synced carb to best of my ability w emgo dial guages.
And did my best at air screw adjustment. Seems OK didn't use dead cylinder kinda scared.
I had a few air leaks in boots I used some gasket seal and am supporting carbs w zip ties to upper frame for weight support. Best it's ever been w heavy pods and rubber manifolds
So the question is what direction do I need to go bike runs good until I wanna blow by a bunch of cars.
I read a few threads and saw a good chart of jet to range performance and I deduce main jet.
Mj to big? Everyone else went up with similar mods
Needle to top just doesn't seem right?
Thanks ahead sorry if I break any post rules I'm a noob.
