Just noticed this thread. Congrats on the Saltare! Glad to see one of the mother ship of the Supra line overseas. I have an '89 Saltare too. Here's mine...



Prices are high over there, but that's to be expected. I got mine, at current exchange rates, for under 6000 Euro. Limited availability in France though, so anything from here will be more expensive.

The other guys were spot on with 6-7 GPH. My Saltare burns about 6 GPH. I ride at 21 MPH and turn 2200-2300 RPM. I have not tuned my carb that well yet, so I expect some small improvement in efficiency once I jet it leaner. Guy who had it before me had it jetted all bassackwards with 84 jets on primary side and 77 (?) on secondary with a power valve on primary and plug on secondary. It was way rich! Right now it's at 74 primary jets and I want to say 80 or 82 secondary with a plug for power valve on secondary side. I run a 800 CFM Holley double pumper. I believe it's still rich so I will jet down further this season and save on fuel. Fortunately gas here for 89 octane (ROM+MON/2) is about $3.40/gallon or .90 Euro / liter It wasn't long ago that gas here was around $2/gallon.

So with the carb, keep the Holley. They're great reliable carbs and are simple to rebuild and tune. Depending on what model carb and CFF as well as any work done to your engine, you may be able to jet leaner. Generally for a stock big block I'd be looking at around 72 primary jetting and 80 on secondary if no power valve or 76 with a power valve. Keep changing jets for smaller/leaner jets until you get a lean stumble at steady cruise then go up 2 jet sizes and you'll be at most efficient carb jetting. There is a lot more to it, but if you get to that point of adjusting the carb I'd be happy to help.
