Jimmy, you bringing that on the Bar Italia rideout? Smallies unite! To be honest I doubt it'll be ready until march 2014, let alone 2013! I did pop down soho last year (again without a running scoot, sigh) but this year I'm on my stag do that weekend. Do you get much stick for riding a smallie round Bar Italia? GS-riding parka types are rarely smallie fans  |

Yeah, but only because they're jealous of my cute ride, flat belly and full head of hair

So jim what's the plans for the engine then standard or tuned beast ? The engine is actually the one out of my ETS, and is already ported and rocking a Polini kit and 24mm carb, but I want to take the opportunity to get it properly sorted. So... * Blast casings to make 'em all shiny like * New bearings and seals * Tidy up ports, as I bodged them a bit last time * Possibly tune the Polini cylinder a bit * Straight-cut primaries * Possibly short 4th * New PM40 chromed exhaust (currently in a box under my sofa) I'm not after creating a monster... I have a motorbike if I want to go fast/get to work on time. Just want something that's reasonably reliable and an enjoyable weekend ride. The big stumbling block at the moment is the intake manifold - I need to have one made that's 3-stud but fits in a V frame, for a 24mm carb. SIP sells one for a 30mm carb that I could use a step-down rubber on, I'd just like to have it 24mm all the way if possible. |

With a 30 inlet manifold and 24 carb would there be a volume problem? Its like an exhaust... tapered just before the end can. But the opposite with a 24 carb and 30 manifold. Or would this not make that much of a difference on a road scoot?

Or would this not make that much of a difference on a road scoot? Yeah, this is what I want to know - whether there's a backpressure element to it. Like, if you stick a really thin drinking straw in a can of coke, it flows a lot faster and under more pressure than if you stuck a really wide straw in. |

My very limited grasp of this sort of thing suggests I'd lose low-end torque if I went any larger than 24mm. That could be a lie, I'm not sure. |

you dont lose much torque with a bigger carb, i run a 35pwk on a rotary and its better than the 30mm tmx on the same motor
you may lose a little down low but then the bigger carb will outperform the smaller all the way

I don't want to go through all that again! Also thinking about rather than sticking my old Polini top end on, going for an alu Evo or Parma... |

If you can afford it, go for it my Parma has been super reliable (fingers crossed) |

Just bought the evo myself, I think it was roughly £280 from sip but wayne may do it cheaper. Trouble is though is the exhaust and everything else that suits it is very costly :/
