I have a complete WR front end on mine which makes the bike a DWR 650 I think, trying to get a decent rear shock that fit's but seems that is a little more difficult. I widened and lengthened the foot pegs about 15mm which works very well and shortened the gear lever 4.9 gal IMS tank, FCR 39 pumper carb, fat bars and a few other bit's and pieces, rode with a bunch of KTM's and a couple of Husky 610's this weekend and was not found wanting at all,,, just need a decent rear shock and to put the hydraulic clutch on.
