intercoolers help...as does decent fuel and of course a good set-up...but then so does riding like a big gurls blouse, commuting 140 miles a day 5 days a week on mine resulted in a new back tyre every month.
my standard b12 lump was running about 6psi.....loopie said it won't last long....I turned it up to about 9 ish and it lasted about 9 miles....so we put some busa slugs in.
