thanks warp , i did have to remove cams and shim 1 inlet ands 5 exhaust, one inlet was .16 and 5 exhaust .21/.22 & one .14 got them with in range .10-.15mm in .15-.20mm ex timing triple checked ok. cam chain seemed a bit loose when first took off cam cover 3mm play could hear it when riding. when assembled I lightly pushed cam tensioner while rotating crank shaft to take up free play. i did take r3 for a short ride after runs smoother power wise no noticeable difference just that fast idle for a few secs after backing off throttle , ill double check hoses cables ok i'll check next the (tps)throttle position sensor
,sorry to be dumb but what is (isvc). thank again
