Fuel consumption/range (Slater Mirages)

You might want to check float heights and pump settings.  Both can influence consumption to a degree, over-metering pumps can blow it through the roof.  The manual states 10ml/20 pump strokes for the 1200 (iIrc), 5ml for the 1000.  I use the 1000 figure for all.  Too high floats ie, setting below 18mm, will enrichen mixture over the entire range. 

I brought my RGS down from 170km/tankfull to 300km/tankfull.  Accelerator pumps are down to a minimum, far less than the manual states, only makes itself felt if I'm trying REALLY hard.  Don't miss anything in everyday street riding.  Carefull setting up should get you in the 6-6.5l/100km range... work it out for yourself, I couldn't be arsed! :D

Cheers Piet: float heights meticulously set to 18mm. Only one pumper working ::)


I do have a couple of minor air leaks at the header/collector joints though not sure if these might be affecting anything other than contributing to a bit of popping and farting on the overrun :o :o

My Jota when I got it ran 155 mains (I think) and was running like a bag of beans...

:o Those beans and your home made water injection, congers up green plants growing out your exhaust.

Does that motor sound rooted?

My bad.. 65s are probably what's in there (memory isn't what it was and it's been a while since I physically examined them to look at the numbers and , yes, I was probably thinking of the 55s in the German 3C)


I ended up winding the screws about two full turns out before I hit peak revs and then backed off ? turn


I think the 1200 tank is ~19L


Hey Macca, you're fairly game riding around on long runs at WOT: I thought that was only possible in remote QLD... shh..

I meant to say that this was on the track...........  but it doesn't matter where you go it's always a great ride. Brand new to this and boy do I love it!
 
Suggest you never buy a JEEP in regards to fuel consumption on the HWY - Great bush machines.

Forgive my Winnie Poo crap.

I'll leave it to Paul, as a fellow Canadian, to explain to our Auzzie's members what a Winnie the Poo is!

not me, I have had enough trouble explaining the "Roto Rooter" trucks they see around here really are only dealing in plumbing services https://www.rotorooter.com/

similar issue with "Roots Canada" clothing store, most Aussie's want to take a branded item or two from there back home  http://www.roots.com/

and back on topic, I have a 1979 1200 Slaters Mirage with conventional 1200 tank, the fuel pumpers in the carbs are still in use but volume dialed down (20 squirts into a cup to measure volume), the bike is good for about 200 kms range before hitting reserve, sometimes even a bit more if just gently cruising (yeah, right.....)

Paul LeClair
 
177 kms at -110kmh before going onto 'reserve' as I pulled into Proserpine. 16.5 L and not much if anything left in the tank so I think Grant's right that the Mirage tanks are smaller than claimed.. got further than I expected tho..

 
If it is any help to calibrate expected consumption - albeit 1000cc.
My Jota 120 with standard Dell's goes onto reserve at about 215 Km's.
Same model with 36mm Mik's about 240 Km's +
Cross referencing with Paul LeClairs 1200 then over 200Km's would seem sensible for the slightly smaller tank if everything OK.
