Scooterotica

I was wondering what the best & worst mpg that scooterist's have out of there respective engine units? Please give a breif spec' of the motor; Cyl kit, Carb & Exhaust used.
IE; Whilst in & around town? Going to rallies or touring? Having a thash down the motorway or A roads?
Be honest & as to the mpg as you have worked out previously!
For example with the following type motors:- TS1 225, Monza 225, RB225, RB250, Stage 4 200, 225, Rapido 225, RB200, GT185, Stock motors also 175, 200 & 225 etc

It will help decide something myself & sticky thought of doing a while back; starting at South Mimms services & seeing how far you would get around the M25 on a gallon or 5 litres of fuel?

It will give an indication then to prospective kit buyers as to their running costs overall for say 10,000 miles a year.

I don't do 10000 miles a year in car Ian yet alone on a scooter!

here are a few of my results;-
1.225 rapido,jl4.34 dellorto.gp gears,75mph thrashed every where good scooter to ride 40miles to a std tank thats less than 20mpg ,this was a cylinder bought of ebay.22hp
2.225ts1,jl4 34dellorto,gp gears,again 75mph thrashed every where nice tame ride around town and good on the open road approx 40mpg complete mbd engine 25hp
3.250 rapido jl3,34kehin,gp gears 19 x46 not very nice in town on the open road very strong powerful engine ,alot less gear changing,good touring scooter 50plus mpg.28hp

all these cylinders were tuned sorry no timing figures!

GT186 - out of the box. 30 mil carb and a posh clubman. About 120km to five litres.
That's commuting 30km each way to work. About 20km of flat out and 10km of filtering at 50/60ks.
On a long run, flat out, it doesn't do so many.

TS1 225 with a mild MB tune, Taffy exhaust, Mikuni tmx 35. Standard 12v set up with timing set at 19 degrees (I think) Used for long runs and some local rallies on A and B roads, sometimes motorway riding. 10 mile per litre, solo riding and 7 mile per litre 2 up.

TS1 225 with a mild MB tune, Franspeed race pipe, Mikuni tmx 35. Varitronic set up. 10 mile per litre solo riding on A and B roads sticking to local speed limits and about 7 or 8 mile per litre thrashing it on motorway etc.

Rapido 225,30mm phbh,ancillotti, li150 16/46 - 13miles per litre at 60ish.
Rb22,tmx35, nk rally, gp200 19/47 - 8 miles per litre at 70-75.

SX 200, bored to 225, Wal Phillips fuel injector, Ancilloti exhaust, otherwise std '68 model. On a run was 55miles per tank (destination was 59 miles) so a hopeful 29mpg?

race rapido 200 ,30 mil amal mk 2 on a royspeed manifold open mouth carb, ancillotti clubman , timing is 19 degrees, sx 200 gearing , 30 mpg but theres a lot of spit back , i didnt build it to save on fuel though, it will hold 65 and go to 70's , sounds lovely..

indian gp 200 stage 4 , standard gearing , 22 mil dellorto and a series 2 exhaust , 50 mpg easy sits at 60 .smooth and quiet.

rapido 250,tmx35,taffspeed exhaust,li 150 box,hard riding, 23 bhp 16lb foot of torque,50mpg

85 - 90 Mpg, City commuting with 25-30% on a dual carriageway.

Li125 S2 Standard, Blueprinted cylinder with tickled exhaust port (did 3-4MPH above list speed), SH1/18 carb.
