Hi all,
after having a spare moment in the weekend to have another play with adjustment-frustration kicked in and I bit the bullet and have ordered wevo coupler/clamp/screw/shift rod bushing and lever bushing. Interesting to note when I went through my files all bushing have been replaced before. When I last had shifter out that bush wasn't bad but for the extra few dollars thought it would be wise doing this again with the shaft bush so then there will be no 'what ifs' if any issues arise.
Once parts arrive and I've got them in/adjusted I'll let you all know if it sorts 5th to 4th and is any good (fingers crossed!). In the meantime I just need to figure out how to hide the invoice from Mrs Jimmy...
thanks again all for your help.
