I'm a sucker for spreadsheets, here are a few stats about my kit:

Average miles/yr over last 5 yrs - 2,000
Total Mileage since SVA in 2009 (with 5 yr break) 17,000

MPG with 1.8 Zetec on Bike Carbs - 35 (measured on a 300 mile drive up to Coventry & back)
Fuel tank 29 litres, so 226 mile range

Insurance with A Plan:
2019 - £137
rising to
2024 - £167

Actually pretty interesting.

The only spreadsheets I have on my kit car is the amount I need to spend to get it back together or repair the broken thang.

My key takeaways from your information.

1) Kit car insurance has not gone up at the same rate as normal tin tops. I wonder why. . .
2) 35mpg is pretty good going considering its on carbs and not very aerodynamic.

No windscreen will certainly help the MPG

i love stats!

just back from camping trip to Normandy



Average miles/yr since IVA in 2019 - 1100
Total Mileage - 5370

MPG with Hayabusa bike engine - 42 on this last trip
Fuel tank - never measured but at least 200 mile range

Insurance with 2gether:
2019 - £121
rising to
2023 - £146

Quite shocked to work out mine got very roughly 40mpg on a run today. 120 miles for £20. That's crazy from big carbs!

Funnily enough, I was similarly shocked when I found that mine did c.35mpg on a 120 mile commute last week. That includes the odd full-bore acceleration run. And I'm confident (without a rolling road set-up yet but looking at the narrowband AFR meter and smelling the thing) that it is over-fuelling.

I recalculated mine to 30mpg after both legs, but that did include flogging it past many people!

It still does its strange fault, where after you've flogged it through a few gears to peak rpm, and a few corners, it backfires terribly and only works properly at high rpm and throttle.
