K8 fork swap

[Ricardo498]

Hi,I have an 1100H that I've been running 1100M forks and yokes in for a few years.

I'm putting a k8 1000 front end in now.I have a bearing conversion kit,but the ground top bearing race is wider in diameter than the frame bearing cup.resulting in the tapered bearing fauling the bearing cup in the frame.The only way I can see a way around this is to either shim the bearing race up,or grind a tapered relief clearance in the frame under the race.any info appreciated.TIA

I just did a K8 1000 fork install on my slabby. Used 30x55x17 on the bottom and 30x47x12 on the top

I'd just get the stem swapped/another made. Use the original bearings. Never liked those swap bearings.

Hi,I used a standard cup 30x47x12 on top and it's fine,not the ground down shite one.

Thanks

Since the bottom bearing is the same on both bikes, can the M stem be pressed into the K yoke ? Unless the K yoke is much thicker, it should be good ?

Hi,I used the 30x55x17 on the bottom with a seal washer,and a 30x47x12 on the top.I bought a kit but it's really not worth it as you can buy those bearings readily.the top bearing they sent in the kit had a ground down race,which allowed the bearing to protrude and foul the frame,so just got one of Eblag and it's fine.

I believe so but I just got a new stem made, wasn't expensive.
