Joseph Posted July 13 Posted July 13 Right, so i'm digging this up cause its got most of the relevant info in here My mix : '91 1100 frame, Busa mk1 swingarm, the famous CNC mount, adjustable dogbones, k1 knuckle, non OE shock but same length as stock. As it stands, and the bike is indeed still on axle stands, It looks like the spring will be rubbing on the swingarm brace, as if the top shock mount needed pushing back a bit. I was under the impression that using these parts was plug and play ? What am i missing, if anything ? Quote
davecara Posted July 13 Posted July 13 If its the same fitment issue as a Srad, the top mount needs spacing out 10 or 20mm I cant remember Quote
WimBaas Posted July 13 Posted July 13 I have done several conversion. Using all the Busa stuff, knuckle, dogbones etc. With the standard shocklenght it should be plu and play. 1 Quote

And so fitting a Busa knuckle is what will correct the issue ? Edited July 13 by Joseph Quote

It definitely was what i had to do on my other build with a K arm. Quote

Joseph Posted July 20 Posted July 20 According to what @clivegtoposted in his busa topic, it looks like the knuckle i have has the same specs as the busa one. Not sure what to look at next in view of what people say they have done to get their set up to work Quote

Joseph Posted July 20 Posted July 20 Right well unfortunately that double confirms that the K1 knuckle is the "same" as the busa (although different part numbers) Really not sure what i can do with this, obviously welding a new top shock mount like @davecarasaid could help, but no one mentioned that needing doing in the search results, and the frame is powdercoated, the bike is all back together almost ready to ride Quote
davecara Posted July 20 Posted July 20 I think all the K swingarm swaps Ive seen have been done on 750 frames where the shock mount unbolts and its very easy to stick a spacer behind and bolt it back on, I think your frame is gonna need surgery unfortunatley Quote
Joseph Posted July 20 Posted July 20 (edited) So that contradicts what @WimBaassays then ? Judging by the sticker that bike he posted is an 1100 ? Unless it's a 7/11 ? I'm definitely not going to rip the bike apart and cut into it. Although i should have done a mock up build on the swingarm, it would be good that the advice posted on here be accurate, by people who've actually done the job. Edited July 20 by Joseph Quote

This isn't a K swingarm ? Quote

WimBaas Posted July 21 Posted July 21 The bike I posted is a 1100 m. Not a 750. I sold the frame, knuckle and swingarm to Jeroen. Maybe I used a different length dogbones. I am not sure. I had several sizes. @SpikeSpike can you measure the dogbones if you still have the setups? 1 Quote

Dismantled the set-up unfortunately. Quote
wobblegob Posted September 2 Posted September 2 This is a pic of my 7/12 with a gsxr1000k7 swingarm in if that's any help Quote
