big BIG thanks to David!!! we did a full major 'under the plenum' service on my '90 ZR-1 (it was virgin with only 8500 miles on it); afterward, we took it for a spin and WOW!!!! now I see and feel how it's supposed to run!!!!
will be washing it and going to Carlisle this friday morning. first long trip in it since I've gotten it in Feb! thanks again to David for his knowledge and expertise -- I learned a TON working alongside him!!!!
