well i guess I'm about to answer this question myself but would appreciate others input if possible.
i have got my bike running tonight after my top end rebuild.
and since i ran it last i have got some Tyga Chambers on the bike and have modifieyed the air box. (read cut it open as on the Tyga web site)
now while it was all open i though i know ill do what the HRC Jet kit recommends and mess around with my Jets
so prior to my current set up i had it all as standard pretty much except a little larger on the main's 142 or so and with all the other jets still in place.
now the HRC thing recommends plugging the PJ's and a massive increase of the MJ. ? is there any one on this site who actually runs on the road without the PJ's ?
I'm thinking i should go back to what i had and worked and just adjust the MJ's;s accordingly
cuz its never going to run with the 180's in it now by the sound of it :S
