Today my wee k9 has been down to projex in cradley heath for a run on the dyno. Main reason I fitted a K&N filter and it seemed to of lost some of the top end power. The bike has done 20600 miles so would also be nice to find out if the factory power figures were still there which is 63.5bhp and 41.2lbft. I think the factory figures are measured at the crank so apparently at the back wheel it's normally 10% less..So the results. The first two runs showed the clutch was starting to slip at about 8,000 but on the third run it didn't which was a bit strange. But explains the top end power loss. Well at the back wheel it made 60.58bhp @ 9142.2rpm and 38.4lb/ft @6937rpm.
Working on the 10% difference its making a bit more power than Suzuki claim. The only mod so far is the k&N filter. fuelling was pretty much spot on just a little rich on the top end. So I'm well chuffed with these figures.
