what of Monza 225

[Bufficus]

has the JL4 got better ground clearance than the JL3, or does it scrape over every speed bump as well

any idea of the thickness of metal used, hear it is a thin and light as a race pipe

It's lower than a low thing.

With the JL4 the power comes in around 500rpm after the Devtour, but the JL4 makes more power and hangs onto it for much longer. I've got both. The Devtour is currently on a shelf.

Alright, just ordered myself a new Monza 225 kit, the version with the Supermonza Meteor piston and double boost port and I already have a full circle 58/115 crank.
This will be fed by a Mikuni TMX30 and as a starting point I will be using a Kegra race exhaust.
What can I expect from this set up?
Is the port map identical to a TS1 225 or are these better, and does the double boost port make any difference over the TS1?
Apart from enlarging/matching the transfers, do I need to do any more work, like widening the exhaust?
