Hi My 1100 evo was due a full engine service, oil valves, belts etc., at 32k miles & I wanted to dial in the cams if required. Should have done this ages ago, fantastic result. The bike was remapped a couple of years ago & was as I thought as good as it gets, was tractable down to 2500rpm & night and day different to std. However after doing the cams it is so smoothe, easy to ride in town or filtering & feels loads better everywhere in the range, now make far less gearchanges, would you believe 30 mph in 4th is usable, picks up nicely (not talking handfulls of throttle at low revs). Read up all I could on the net & made a degree wheel, crank turnong tool, TDC dead stop finder & borrowed DTI. When checking, both were out about 3 & 6 degrees f & r. checked this several times & got consistent results. Set both the same on the intake to factory spec. This all took me a few evening but well worth it & next time should be rally quick to do. Make sure whoever services your bike does this, should be done after belt change but fear some dont... 2012 1100 evo 32 k miles MWR Airfilter & airbox mod Leo decat, valve removed CJS remap (the crucial bit) lambdas disabled
Yes they are adjustable, there is no 'vernier scale' as such, just position the crank at the correct point for 1mm valve lift, losen the pulley, 3 screws, & rotate the cam until the dti reads 1mm.
Yes that's what I was getting at that the cams had elongations at the bolt mounts , where did you put the dti gauge .... on the rocker arm through the inspection covers , quite surprised it's made such a difference really , I have done car cam belts and they have been miss timed by a tooth advanced / retarded and not found much difference in the power .... every engine different mind , maybe Desmo more critical , good tip anyhow
I'm not saying necessarily big power difference, mainly part throttle behavior is much better, crisper, more responsive, (does feel like it pulls harder though). DTI axis needs to be exactly aligned with the valve axis, I put a wider foot on the end of the shaft & this sits on top of the closer shim, note opening rocker clearance must be shimmed out (use feeler gauge), bolted a steel plate through inspection cover hole & used a short articulating adjustable arm with mag base on the plate. I guess with a bike opposed to a car small differences are more noticeable due to power:weight ratios.
