****VERY BIG GRIN****
 :twisted:  :twisted:  :twisted: 
after driving the pickup for the last year i got into the disco and thought it was quick.... i`ve done the tinkering as described..... and was pleasantly surprised by the result... once that snail thingy spins up it moves! and the exhust has that lovely jet-engine like tone on high revs!
....just like the fourtrak did, hope the clutch holds out! :lol:  :D 
very pleased!
clean intercooler to fit next, and that will do me engine wise (well rocker gasket to do, a clean.... thats it for now!) 8)  :D 
follow the muddy blue blur! :D
