Dan,
Hope that you do give it a go next season, because in 2013, apart from the Shootout (which was good), we have been lucky to see more than half a dozen scooters at other meetings - probably down to the current economic climate etc.
Having been sprinting for 'a little while now'..................
What you are looking at really is IMO the biggest weak link for scooter competition on Lambrettas, Racing or Sprinting, i.e the transmission, just about everything else apart from rear hubs possibly, has been sussed.
Pacemaker gearboxes ..............as Paul has hinted at...............forget them.
Martin's SX 200 conversion is a good one....if, as you say, you've got the SX gearbox in the first place.
Sean is spot on re selectors, use Indian ones, the Italian ones, for sprinting, are an expensive and an unnecessary luxury.
At the risk of stating what is not always obvious, the issue with gearboxes in sprinters, compared to circuit racing, is quite simply that scooter road racers are punishing their gearboxes but not in the same way - I'm sure this will cause some comments btw.
i.e. every run you you do up the strip its a balls out start and clutchless changes, remember roadracers only start once each race so the damage they are doing is through all of the gear changing, not as we are doing, basically knocking eight bells of s**t out of the gears on every run and we don't have the chance to recover any errors like missed gearchanges on the 'next lap'.
Some years ago I was told that Ducati WSBK bikes, at the time, could not take many race starts due to 'gearbox sensitivities' - so we're not the only ones with gearbox issues.
So if you have a trick gearbox done, the reality is...................
What do you put in when you break it?
i.e your spares...........
Answer, you move back to boxes that are readily available or have something made that you can't break (£££££)
I would consider a Cyclone 5 speed if I knew that it could take the pounding....I'm not prepared to spend £600.00 to find out!
So hope that above is of some help to you in your deliberations.
