well, as you may have seen in discussions i´ve wrote down that Max jetted his bike fatter on cyl1 than two.....
165-160 if i recall correctly. Others said it should be other way around....
Was out for the weekly upstart just now and thought i´d put my hands on the exhaust for a while....
For SURE cyl1 is heating up faster than two.
Will try a different jetting for next dyno but not a .05 but .025 difference.



Yeah, just wanted to let y´all know.....

when mine was in std trim the right ,,No2 downpipe always went red before No1 , and all my valve clearances ae bang on

1 goes WAY hotter than 2 faster, mines always done it.. never figured out why.
