That snug fit of the resonator against the engine will allow you a bit of room to clamp a custom heat shield if it poses a threat (!) It is tucked away, but might could use a shield.
I have seen builds here on this site that involve headwork and opening up the exhaust sytem to improve midrange torque (esp) and I've heard the phrase "willing" or revs easier too. I also hear of people struggling to make a larger bore carb work, unsuccessfully. It is the "go to" upgrade.
My OEM Youall carb on the Templar is very dependable. I do have it jet on the rich side. I should lean it out a bit for better running when hot, but it isn't really that rich. The primitive shim method can work nicely for the needle, and I didn't mind drilling out the airmix screwcap and extracting the float bowl screws. I really have no reason to replace that carb now until I follow through on porting, slight overbore kit (to 265cc), and get a pipe on there with a resonator. Then a better carb would be a good idea at that point.

That resonator is a large cell catalyst. Or at least pretending to be one. The individual cells are rather large, so I don't see it being very restrictive at all, especially with the exit being essentially the same size as the catalyst itself. No bottle neck like the stock system.
It does actually have a decent air gap to the cylinder as well. My fear at first was that it would end up too close, but after making my mid pipe bracket ala Hardware store, it moved it away enough that I am not concerned about the proximity too much, but I do have a heat shield on the way, more to protect me and my leg than the bike.
Having basically played every mod game with this bike, I have come to the conclusion that the "ultimate" modded street ridden Hawk = Motocult kit and a VM26 "30mm" clone, and an exhaust.
The VM26 Clones aren't really any different than the stock carb other than the choke working backwards and the bowl has 4 screws instead of three. The key difference is the fact that they use Mikuni jets, and Mikuni jets are simply superior to Keihin. They function as a tapered metering orifice instead of a basic hole. That just seems to make them run better. Better than the PZ30, which is more or less the same carb.
Maybe I am giving up half a HP on the very top end by using this carb over my PE28FL or using something bigger, but most of the bigger carbs have fitment issues and become tempermental with tuning.
