from what rob posted earlier, the 954 shock is not a good option. be advised the 929 install will require some trimming of the battery box. i made several spacers of different length from 1" steel round stock. i have since decided, even painted they would start to rust. (yuk) i bought a length of 1" square bar stock of 6061 aluminum. part is much better (not perfect but i'm trying). the most critical part is the top mount hanger. the 10mm bolt has to be removed and replaced with 120mm length, welded into place. and then the bolt head has to be ground down about half its height. the stock hanger costs $12.01 plus shipping from ron ayers. so they raw costs of parts for me is about $20. rob made his own for $2 ?. having a used hanger would save the $12 but how long would the bike be apart waiting mod. if your still interested, send me a PM
