I read somewhere on these forums that the clunck of the transmission can be improved by replacing the bushing in the reaction rod (at the swing arm pivot end) with a Stelvio one. I didn't have a Stelvio but went ahead and pushed it out. To my surprise the bush was nothing like the Silentbloc I expected but was as the photo shows. The whitish bit is a white dense foam cushioning ring. The one seen may be reasonable but the missing one came in a thousand pieces. The centre part is a GE12FW (Maker Chinese CCVI) and is a spherical plain bearing. The purpose of this bush appears to be to allow a small amount of horizontal twist of the reaction rod and the rubber rings are to seal the bearing and provide a buffer of the rod twists too far.
Thanks to 'draidt', I have ordered a Silentbloc bush from a 1200 Sport part no. 883045 so I shall report further when this part arrives from the USA to Oz.
It may not be clear from the photo, but the GE12FW is the centre part only. MG have pressed in two flanged sleeves from either side and reduced the diameter from 12mm of the GE12FW bearing to 10mm.
Cheers
