HERE WE GO:
I was asked by another member to provide the install steps for the GenMar 1" up and 1&3/8" back bar raisers for my B1250. Unfortunately I didn't take procedural photo's but I remember it well and these steps should help.
(1) Make sure the bike is cold and on its center stand with the front wheel blocked strait forward. Read each step completely before proceeding. You will not need to replace, bleed or disconnect any hyro lines. You will however need to allow the slack to be taken out of the hyro lines by loosening and un-sticking the two front brake line support clamps down by the right front forks, which will allow enough slack for both the bars and allow shock movement. You will also have to remove the left clutch line clamp permanently located on the left side of the frame just under the tank. Make sure available slack in hydro lines is available all the way to the top of the bars.
(2) Remove the top clamp of the stock handlebar and temporarily set the handlebars with everything attached to rest just forward of the handlebar clamp area. Now do a pre-fitting first by inserting the GanMar bar raisers into the stock lower half moon recess, and temp install the longer bolts and top bar clamp provided without the handlebars. This will give you an idea of how it will all fit together before installing the handlebars, making sure there is no binding and new hardware provided fits well.
(3) Straddle the motorcycle (climb on) with the bike on its center stand. Now reach forward and place the handlebars into the GenMar extended recess (toward you) while simultaneously installing the bar top clamp and long Allen bolts provided very loosely. Make sure all hydro lines and electrical harness wires have slack to come back without forcing! You may notice that the handlebars look as if the will not fit into the GenMar recess because it is supposed to be a tight fit (normal). DO NOT worry about handlebar position at this time, only right and left center splines. Tighten down the bars enough to get them barley seated and loose enough to move the bars back toward you or forward, but DO NOT move them yet.
(4) The handlebars are now centered and tight enough to be held in one spot but loose enough to force forward or backward but you should only do this a few times so as not to damage the splines on the handle bars too much. The fewer times the bars are shoved forward and back the better. Now before grabbing the bars to adjust place your hands and arms out forward for a few moments to imagine the ideal position for you. Now yank and places the handlebars at the best location and position for your reach and liking, insuring again the splines are centered. Then tightened the bars down slightly snug and loosened the right and left hand levers to better accommodate your new hand position relative to the the new handlebar position. You may have to use a combination of both handlebar and hand lever adjustments depending on you liking and the ability of the hydro lines and electrical wires to accommodate the desired position.
(5) Once you have set your handlebar and hand lever positions, you need to carefully verified no binding of the hydro lines and electrical wires by turning the handlebars to full right and left stop while ensuring nothing is binding or stretching. Now can you tighten down the handlebar clamp Allen bolts evenly so gap space on each end of the top cap is even front and back. Also you will need to replace the two front brake slack clamps in there new positions, providing both handlebar and shock movement slack. The left side clutch line clamp will not be reused and the clamp itself should be removed to prevent snagging. If any of the hydro lines or wires don't seem to be able to make the stop to stop range of motion, you will have to make a compromise between the handlebar position and the hand lever positions. Mine fit fine.
