yeah thats what i'm talking about, the minarelli horizontal stuff is super well supported and not far off from a QT cylinder, and you can make an adapter for big hoggin reeds on the crankcase.
i don't know the hoca port maps at all, i installed one of their kits a long time ago on an express i think? i don't remember, fit and finish were ok. Taiwan mfg i think. anything nicasil is going to be worlds better than cast iron.
the minarelli horizontal stuff is all supported in 10 pin and 12 pin, the 10 pin is common on the yamaha (zuma, jog) where as the 12 pin is prevalent in many of the clones (TGB, etc). 47 mm '70cc' stuff for them is so common and you can get up to 20+ hp stage6 cylinders.
its definitely interesting to see what a pro porter would do with that malossi kit. i realized a long time ago its better to start with a more expensive kit, than put the time and money into trying to make a lower end kit work. Even having ported lower end kits to higher end port timings and specs on paper, they don't always perform as well because the transfer shape and direction has to be modified so much. I've taken a few cheap kits to the max with 10+ hour port jobs and its just not worth it if you value your time at all. you're better off starting with a good factory-designed kit that does what you want and making incremental changes a few degrees at a time until you find the sweet spot.
thats why i've never had much faith in anyone that does 'pro porting' because the only way to really max things out is guess and check and guess and check and tune and guess and check and tune and check... etc etc. the best money you can spend on dialing in a setup like this is buying about 10 base gaskets for the 10 times you will have that cylinder off making tiny changes. I've ported dozens of these cylinders and the only way to really get them running right is keep making small changes and just fine tuning.
having a dyno is awesome, that will certainly speed up development and let you really get it dialed.
