Yup.. You can use CRF/XR 50/70 tapper bearing kits. Can be found for about $20 on the mini sites. You will need to make a new steering stop for the CR's trees. The 86-89' CR forks can be lowerd a little with a small spacer under the damping rod. Damping holes are huge, you may still want to play with fork oil weights, oil heights and air pressures.
