, they where going to retrofit the pre85 ones back to pre75 specs.....how you do that boggles me?
The rules for the pre '75 sidecar class are a little more lenient compared to solo's.
Basically if the engine is pre '75 or follow on, drum brake rear, period front disk and pre '75 spec non piggy back, pre 75 suspension travel and geometry- you're in.
This rule was made (correct me if I'm wrong) to encourage more entries in the '75 class and to make use of all the mid-late 70's wasps that are little better than the pre 75 ones.
To convert Nick Higgs' 70's airbag EML or Vaughn's '76 (?) wasp- relatively easy and in the spirit of the 'loose' rules.
To convert Ronnie's or Dave's or my 83-84 EML- waste of time it would be a piece of shit.
