TOPIC:

Does anyone know if the Katana alloy swingarm has offset shock mounts ?  I have the swingarm mounted correctly in the frame, and with shocks mounted to the swingarm, the sprocket/left hand side shock sits out around 10-12mm wider then the right side shock, is this normal ?   Its mounted in my 1982 GPZ750 frame. I won't be able to get back to the bike for a week so I thought I would ask here before measuring everything accurately, I ran out of time yesterday...
Thanks.

It might be that way to clear the chain and sprocket.  I know the stock swingarm on my GPZ1100 was not even left to right, there was more room for clearance on the left than right.

Yes, that's what I'm assuming , Hoping someone that's done this conversion, can chime in so I know for sure, I've moved my top shock mounts and I have to trim the newly made shock mounting posts  to suit, I made them both the same length, once inserted in the frame and checked with the shocks in place I discovered the left side was correct but the right side needed to be trimmed to make the shocks sit straight, Just wanted confirmation before I trim the right mount to suit...
Thanks for your reply..

I am using a GSXR600K arm in my 82 Ltd build, that is also 11mm further out on the left so I guess this is the norm. Calum used a GSXR arm and relocated top mounts on his build, might be worth dropping him a message
 

Well mate! i have a Gs1100e swing arm on a Z1000 A1 but there is a GSxr rear wheel on there and i spaced  the swingarm over to the exhaust side (right) by a few mm and the spaced the wheel back to the chain side to achieve the wheel center giving me equal distancing on the shocks which is around 8mm either side (8mm spacers on the inside of the shocks), if i can help with photos just let me know.

Thanks mate.   I have the spacers on the pivot bolt equal on both sides at the moment, I may just put them all on the left and see how that goes. I haven't made all the spacers up to centre the rear wheel yet, so that's not a problem either. My OCD wants everything to be perfectly squared up but it looks like compromise will prevail...! I won't be able to get back to the bike till next Tuesday, that should give me plenty of time to obsess....

I hear ya mate, i could have done things by not having the swing arm offset but It didn’t feel right to have the shock spacing uneven, I’ll take what photos I can in the next day or 2, Working on bikes have taken a back seat to my actual job now that summer is here but I’ll have a bit of time on the weekend in the garage.
