mmmmm. Nice set of curves! So when's the new dyno day? I'd like to think with the mods we've recently made to the 3XV-R we could beat the other 3XV and the MC16 (what's going on there ). I'd like to run my MC21 up too, so that I can get an idea of where I need to go next with the Honda. It keeps giving me neglected little looks from under the 'blanket of shame' every time I pop into the mother-in law's garage. Must get it sorted in time for spring. It's actually a very pretty one and in very good nick really. But the motor just doesn't feel quite right. If only there were more hours in the weekend...

Cheers

The '16 is held back by ickle carbs and even smaller exhaust ports... Both of which are easy to get around if you do a Jeff and fit '18 barrels and carbs.

Dyno day, you have a PM.

How come Andy's monster SE isn't up there? Come on mate, don't be shy!

Its the leader board not the almost board lol

If I posted all the graphs from each model I would have to post the worst ones as well, and some are some people dont like their graphs being laughed at for some reason

Took my MC21 down to Chris at Road & Track Dyno at Aylesbury. It's putting out 62.2bhp with Tyga pipes, modded airbox and M-Max box .
I was quite chuffed considering that the engine hasn't been fettled with!

Do you have any Aprilia RS250, RG500, RD/Z350YPVS, NS4R ?

Lets have a stroker collection, there are not many strokers so it should be possible to get a complete selection, to help buying decision when we are considering buying that third, fourth or fifth 2 stroker ?

Any road up.....going back to the dyno graphs. I think that we need to throw out the F3 'cos we all know it's gunna kick ass

The RGV in second doesn't count because it's a Suzuki, and it's got the same sort of mods as Steve's F3 but it's 5 gee gees adrift, which is a rather poor showing

The Krapperkazi in 3rd is very impressive for a 200 year old parallel twin, but it's green so it doesn't count either. No one wants a green bike...seriously

So this puts the antique MC18 top of the charts

Probably.

Not got any 18 barrels yet But i do have a whole MC18 to kick Yamaha butt with

We could port the hell out of the 16 ones Jeff and see what happens!
