Hi guys, thanks for the warm welcome.
Andy - I appreciate your offer to assist, but Scott (thommo) may be able to offer some local support from 'up the road' (just about, anyways). I'll try that first and see how we go.
Scott - Coincidence indeed! I'm in Tumbi, not far away. Would be happy to catch up and have a yarn to discuss your build. If you happened to have a set of mounts and are happy to part with them, well that would just be awesome. I'll PM you my mobile # if you want to fire me a txt and I'll get in touch with you.
I'll get some teaser photos up later this evening. In the mean time, a quick run down on the engine mount situation and bike history.
As far as I can tell, the bike started life as a red/white/blue r7n '90 model. Some of the panels, the motor and rear shock appear to be from a '92 SE model. The swap was performed just prior to sale so I don't think the bike received a decent 'shakedown ride'.
On the first ride I immediately noticed a bad vibration and clunking at 5000-6000 rpms. The torque arm is installed, though the bushes are a little sloppy, however I noticed the rear right upper engine mount is missing (I have only one item 17 from the mc21 J-14 microfishe instead of two). Some gentle pressure on some vice grips locked to the torque arm allowed me to rock the engine some 3-5mm. A look at the front engine mounts shows that they have significant movement too.
Looking at the parts microfische, it shows different engine mount part numbers for the r7n model vs all others. I'm assuming that the main frame remained unchanged, and the engine cases (as far as mounting goes) remained unchanged, and you could use either the 'old' - discontinued - r7n mounts, or the newer style mounts, so long as you don't mix and match between. If any of you could verify this, it would help set me straight and I'll be sure I am sourcing the correct ones to address the problem.
When I drop the motor I'll have a better idea of what i'm working with, but any insight in the mean time would be welcomed.
Cheers
Scott
