If they're good damping shocks & you're happy with them could you somehow raise the front end to get it in proportion plus the added bonus of a bit more ground clearance & footrest clearance when cornering in deep grooves. Trying to think what i'd have done to my B33 back in the day [ideas probably frowned on lol but] Shorten the top bush & add a bit to the spring or preload it more if it won't coil bind. Forgetting it has external springs--was long ago. Or--add a screw in lengthening spacer to the top of the tube where it fits the top yoke. Or--ignore all that lol, just reminiscing. Cheers.
ps, have a laugh at my old dunga from back in the day. String & wire special but went like hell on methanol, or as it was called--Shell racing Special & it didn't sting like petrol if it escaped the tank cap & got on your racing pants or places that you wouldn't want it lol. Apologies for hijacking your post, i'll show you mine if you show me yours-----ahem.
