Thanks for the generous words, although I doubt I am that worthy . . I actually don't remember how I got the idea so I can't claim credit for it, not that I really care anyway, mainly because they don't offer a set of steak knives with prefabulated amulite blades and finely crafted, artisan designed, faux wood handles and a four place setting of monogramed paper doilies for good ideas here.
Actually, I do [or did] a lot of chamber measuring because I build high perf engines for street cars and thought there must be a better plate that’s easier to work with for motorcycles.

Made up an etching of the ports of a tri z barrel.
I have not ran it so can't comment on performance, but it has been ported and it looks to be good work.
Exhaust port is 58mm wide x 37mm deep and 35mm from deck.
Expecting more top end!

^ That's a wide exhaust port for a cylinder with no bridge, I hope it works out for you.

The motor it came from was off ebay bought for the crank cases.
It had been snatching the rings but the bore and piston were fresh, there was no chamfer round the ports which I had put down to poor workshop practice.
I added some chamfer and it runs smooth so was going to give it a try.
It's on it's penultimate bore so I guessed it must have been ok prior to last re bore?
Worth a punt as it came with fresh rings?
But I appreciate what you are saying.
Mexico sorry for nicking some of your thread

I don't think you are measuring it correctly. If is was truly 58mm it would be into the transfer ports. The measurement is to be taken straight across the port map with the map wrapped around the piston, NOT flat as I suspect you have it when you get 58mm. All other measurements can be done flat, but the horizontal measurements are to be done across the arc.
You also want at least 6mm between the exhaust port and each of the transfer ports, or something bad happens with the flow. Maximum exhaust port width on that jug with a 70mm bore would be about 49mm. If it's bigger than that you'll be too close to the transfers and the rings might catch.
No I am not an expert on this topic, but I have been reading about it for months and I did stay at a Holiday Inn Express a few weeks ago which means nothing to you on that side of the pond, but believe me it's critical to this topic.

If that was in Mexico, wouldn't it be called "Vacaciones en Express", or did I just did I just say that I would like to have a quick vacation with your goat?

We actually have them down here. What we don't have is La Quinta (Spanish for "Right next to Denny's") go figure.

How are you getting an accurate measure?
Will have a butchers at it later.
