Terry how did you end up with so much speed equipment you dont like?? Did you ever try your Dellorttos?
Well, I bought the Dellorto's from a car guy, then found the only NOS manifold in Oz, and Daniel was nice enough to show me a pic of his linkages. I never ran them though, the weight really put me off, and Mike Rieck advised me to buy the CR's to suit the head he built me.
I did get to ride a Dellorto equipped CB750 based 1200cc bike, (built by Rex Wolfenden, Australia's premier Honda CB750 builder and racer) and it went extremely well, but of course, considering the engine mods it'd be hard to tell how much difference the Dellorto's made, and the new owner replaced them with Mikuni flatslides shortly after buying it, but I don't remember why.
I'm a big EBay fan, and I discovered quite early that there are "performance parts" out there that if bought cheaply enough, can generate enough money for more desireable items. The Webers, Dellorto's, ARD and RC Magneto's etc can generate quite a lot of money as they're very popular with the retro chopper guys in particular, because they do look cool. I've still got 3 ARD Mk2 magneto's for Kawasaki Z1's, but the Kawasaki guys aren't as interested in them as the Honda guys are, so they're harder to move. I must machine them up to fit CB750's.
The CR's are very well priced at around 700 bucks a set brand new, but you can normally pick up the webers or dellorto's a fair bit cheaper, and now that guys like Daniel are selling new rubbers for them, they are even more desireable. If I see another set of Dellorto's (or Webers) I might try them out on the 1060 engine, as light weight won't be a #1 priority. Cheers, Terry.
