Hi guys quick question .
when I start the bike it's running on 2 cyl . 1 and 4 .
if I rock the bike left to right , rpms increase for a few seconds. Which I'm assuming is the bike running on all 4 .
I have to keep rocking the bike back and forth , otherwise it goes back to running on 2 cyl .also sometimes after rocking the bike and shutting it down .expecting 1 and 4 header pipes to be hot , it's sometimes 2 and 3 or even 1 and 3.
sounds like a fuel delivery issue ? I have new pump new petcock, new filters tank and inline .pump puts out the specified volume. Tank breather is good.
I had carbs rebuilt when I got it . But I think all he did was replace everything under the float bowl covers . I don't think he separated each carb.
sounds like my enrichment circuit may be clogged ?.
any advice greatly appreciated.
