Dennis, Before changing the cam chain tensioner i inspected the timing marks against the Honda official manual so that i could make sure to duplicate the exact positions.
But I thiink the cam timing is not setup correctly to begin with - but i'm not possitive. I set the "T" mark at the TDC index on the compression stroke (cam lobes up on #1 cyl) but the cam sprockets are "down". See picture files i uploaded to the files section. There are 3 files name .....comression stroke... that show the various comonent timing while at TDC. "T" Mark at TDC: http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+T+Mark+at+TDC.JPG?gda=hFSU6FIAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnzwBqVWlehG97cPOCAMbdUyFbLe6sfyG_qsoPQmfGWP_BVeLt2muIgCMmECKmxvZ2j4IeqPHHCwbz-gobneSjMyE&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Compression+Stroke+CAM+Sprocket+Position+Mark.JPG?gda=AdoyrnIAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnzz4p38_EeQ3ASq8C1YDSfKrEI-0wyrxDMJFem9XTDq77Jq5GodiV22Lrf0Fg6w3fAnxctj-Psmv64Nn4Wag7Qe5V4u3aa4iAIyYQIqbG9naPgh6o8ccLBvP6Chud5KMzIQ&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Compression+Stroke+CAM+Sprocket+Position+IN+Mark.JPG?gda=H_L6YXUAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnzz4p38_EeQ3ASq8C1YDSfKrEI-0wyrxDMJFem9XTDq77Jq5GodiV22Lrf0Fg6w3fAiKfvge6whW9fK0jc2GAFWh-Kp228GWTjeb0x8aV_WGQGu1iLHeqhw4ZZRj3RjJ_-A&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Compression+%231+Cyl+Lobes+UP.JPG?gda=yZ-4XWIAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnzz4p38_EeQ3ASq8C1YDSfKpshvORhWiX90f1T0QPIxeVRJOy96qjJdnoqYSzMRI1p1Xi7dpriIAjJhAipsb2do-CHqjxxwsG8_oKG53kozMh&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc Then i rotated the crank one revolution exactly so now it is at TDC on the exhaust stroke. In this case the the cam sprockets are up and the #1 cyclinder cam lobes are down. http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Exhaust+Stroke+CAM+Sprocket+Position.JPG?gda=eaHdIWkAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnz4D6S9ll8ZdT99gjzGPGu4NiLzl7u0-jTC7LUbn2SDpGVe0_5cnVeRaEbz8CeVVlPkJh5MenIyGLBNESi9y05ByECKgQbmraGdxlZulaYnsh&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Exhaust+Stroke+CAM+Sprocket+Position+IN+Mark.JPG?gda=tl3Yv3EAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnz4D6S9ll8ZdT99gjzGPGu4NiLzl7u0-jTC7LUbn2SDpGVe0_5cnVeRaEbz8CeVVlPg_6QxLG-mTHxOut71kRTixTCT_pCLcFTwcI3Sro5jAzlXFeCn-cdYleF-vtiGpWAA&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc http://16481440758028870596-a-g.googlegroups.com/web/650+CAM+TIMING+Exhaust+Stroke+%231+Cyl+Lobes+Down.JPG?gda=xoVCw2cAAACTdSkmtVVI9OXF2ygg83pH-2Bfsuxgn9oyE9mWUwcnz4D6S9ll8ZdT99gjzGPGu4NU5iLDCThIwO8n_xNTiz4HimFscX5cJF9zpfs33myyaYW5vdZGTPoFdJZ03CIMmih5Xh26_qkMwaGGFl2NCU0D&gsc=F0q8EwsAAAD38wzirucqs8P_zxsE_Nnc Does it look like the cam sprockets were installed 180 degrees out of phase with respect to the #1 cyclinder cam lobe position. It seems that this would also caus the valve timing to be off slitghtly. The bike currently runs a little rough at idle, but pulls really hard from 3000 rpm up to 7500 and then at 7500 it pulls harder.
