Oh and I completely found the rubber plugs that are suppose to cover the pilot jets missing (on order now) but that shouldn't affect high-end bog, right?
On my 1981 xs400 special 2, I believe the main jet is 135 and rpm bog and slight surging happens at 6500rpm or so, should I up the main jet to 140, or try adjusting the needle up a clip?
again it revs completely fine when clutch is pulled in or at neutral.
Damn nice, I bought my 81 xs400 special II for 700! It sat in a barn since 1986 with only 2100 miles on it! I brought the beast back to life to ride on.
I have the same problem. In nuetral or clutched it will rev to 10k, but in any gear It will bog at 6500-7000. If I work the throttle a little I can surge it passed 7k, but it's wonky. I'm wondering if I I can move the needle up a postion to let more fuel in? or possibly a larger main jet.
Is it okay to chop the exhaust right before the crossover pipe and custom fit mufflers and hangers? I can seem to find any aftermarket pipes and I hate the stock megaphone style. Thanks!
