Well everyone should know by now my love of the Joe Hunt maggie, thats been the best money ever spent followed by Jim's Flatslide carbies, they work so well together, but more power and speed the next thing was the Grimca 12" floating disc, calipar, M/C and S/S hose and now it stops like a moden bike, Lansdown front end kit.
Other things I have done since I have owned my 850 from new
57 Wideline Featherbed frame
Motor rebuilt for the Featherbed frame
Akrot alloy rims
Better tyres
Round centre mount alloy oil tank
Koni rear shocks
I am sure there are somany more things I have brought over the 39 years of ownership
