@calum nope

@terry-tz servo assisted.

YEIS installed?

What carb you running?

[terry.tz]

like I said it might just be me I'm going to clock it

it's at 14546 il top it up tomorrow

@calum Mikuni flat slide not measured but I'm under the assumption it's the original so 28mm and no servo its pinned

[Calum]

@terry-tz So you will lose fuel economy with servo pinned, that's just how two strokes work.

With the servo pinned, fuel is just spat straight into the exhaust port.

The servo alters the exhaust port height, allowing the expansion chamber to force this lost charge back into the combustion chamber. Like in that GIF.

So yes, it will affect fuel economy. Also with servo you can spend more time at the lower RPMs without losing rideability.

@calum ye I know just didn't expect that much difference, to be honest, i been working out how many miles I have been doing it's a lot it's totally just me because I'm fueling up allot and holes are being burned in the wallet

[Calum]

@terry-tz Yeah but think about it, my bike happily poots along at 4k, so I spend a lot of time there.

The YPVS is allowing the exhaust to force the lost fuel air back into the combustion chamber hence why it's got torques.

If I were to poot along at 8K, you're twice the revs, so near enough twice the fuel.

I think it's me anyway I ride it like I stole it at the moment I'm just getting over the withdrawals of not having a bike for a while under estimating the miles am doing
