The triple turned out to be a bit of a challenge.
The KTM stem was too short.
Ended up using a stem from a 05 Yamaha R6. Pressed it into the KTM lower triple.
Next up was the bearings. The headstock on the 650r is 55mm id and the stem was now 30mm. Ordered the tapered roller bearing kit for the 650r from all balls but the id was much to large. Made a couple of spacers, pressed em on with the bearings.
Ended up using a Universal brand topclamp for a KTM. The stock KTM top clamp has the pinch bolts on the rear and they would hit the gas tank at full lock. The Universal has the pinch bolts at the front. The triple now clears the tank at full lock.
