The suggested fix is to put rubber spacers on the engine moutine bolts. The June 1984 issue has this to say: Rubberized Spacers sometimes used as engine vibration dampeners on the R65 are available from Jesse Fowler (Mid-Michigan Cycle)at $20 per set. The term engine vibration dampeners is really a misnomer, since you are really dealing with frame harmonics here rather than engine imbalance; you cannot cure the problem with engine balancing techniques. These spacers consist of a hard rubber buffer sandwiched between and firmly fastened to two steel washers. They replace the 8mm metal spacers on the front engine mount on the R65; one of them is notched to clear the oil filter cover. I happen to have an R65, and it certainly does vibrate. All the same, it is a relatively small range (about 4250-4750 on my bike), and I find that, when I do use the engine in this range, I am merely on my way out to 5000. By riding this way, I find that the vibration is hardly a great annoyance. Because the R65 has the famous boxer's torque from below 3500, I rarely go above 4000 in the city, and I like to keep the rpms up when riding through the canyons. ______ / \ _______| |_______ / | Darryl | \ ___/|________|Richman |________|\___ / | | | | | | ...!ima | | | | | | \ | | | \`|'/ | !ism780 | \`|'/ | | | | | | -( )- | !darryl | -( )- | | | | | | /| |\ | | /| |\ | | | \_______| |___ ___| |_______/ | | |________| | | `-' `-'
