Hi, some experiences of the Mass Mohave. They don't burn if you hold the heat shields on and do not ride with shorts.
The side panel do not melt, at least when it is a scrambler side panel. It has a built in heat shield.
Did polish mine by hand didn't like the factory "raw" stainless steel surface.
They are euro 3 proved so they are legal here in Finland with the original baffles on. Do not like the original baffles they sound ok but they are too much restricted at least for my engine. NARK, AI removed, 155 main jets. Worked with TORs superbly but not withe Mass Mohave euro 3 baffles on.
You can take the baffles out but then the noise level is HIGH. A Harley sounds like a scooter after that.
I put some simple aftermarket baffles and lots of glass fibre wool around the baffles and after that the sound was just perfect. Deeper tone, loud but not too loud and the engine didn't loose any performance. Like it a lot.
I put a short sample in the video thread. Go and listen.
