Time to Modify Just a Bit More.......

Kiwi - that's cos you are SOFT!!
My balanced lump has bugger all vibe fortunately but the engine acting as a stress member
has stood the bike in good stead handling wise....

 hard and grim solid engine mounts OMG!! ..no need! vibration on bikes is the WORST..  solid is best on bare-bones stripped race bikes.. or suzukis or suchlike..lol.. i'd take the XS's sweet rubber mounts anytime..

[AussiXS11G]

bespoke solid engine mounts - a must....
bed in with silicon to avoid vibration (at the mount)
there is vibration felt at the 'bars at some revs tho - none in the foot pegs fortunately -
fill the 'bars with lead shot and a fibreglass plug cuts the vibe...

aus, yep 530 o-ring type, did try the 520  but the XS1100  too heavy and beasty for that wimpy stuff.. 520 stretched and sagged before very long..  530 way more heavy-duty

Thx for that info on sprockets, Kiwi
What chain you using ? 530?

[pgnz]

yo this area catches the chain on any 5/8 sprocket over 13 teeth diameter, needs a few mm's of alloy skimmed off for a 14 tooth to fit,  good luck on squeezing in anything bigger diameter...

on mine gearing with 17" wheel with radial tyre 14 tooth front and 45 tooth back = 100 kph @ 3800 revs, down from stock shaft standard model 4100 revs @ 100 kph, any taller ratio loses the sting and gives a soggy throttle in 4th/5th (like the yanks get with their over-geared 750 drives.. heheh)

more over-geared i tried a 38 tooth and skinny 520 chain, mmwwaha, it sat on 3000 revs @ 100 kph, engine barely awake, 5th gear sweet in tailwinds only, and over-geared not to mention within seconds of hitting the throttle annihilating first gear cogs and slots into a rounded clattering mess only any good for making machine-gun sounds

Work is getting in the way of the job ATM mate
Keep an eye on my photo bucket folder (link in my first post this thread)
for new pics tho
I have liberated the drive from a middle gear case but will probably go for the aftermarket shaft as I won't need to space the rear sprocket to suit with that one also allows use of R1 front sprockets
