I decided to take some sound measurements on my '96 CR500. I installed the FMF TurbineCore QII a couple of months back and didn't notice much of a change with my ear.
So, off to Rampart Range for a nice Sunday morning ride. I also wanted to measure the temperature of the exhaust system, so along with my noise meter, I brought an infra-red temp gun.
The temp gun doesn't work on shiny metal surfaces, so I put on some masking tape in key areas. Note to self: what an idiot. That lasted about 3 minutes, after 496cc's of combustion motivated machinery warmed up. Duuuuhhhh. So I removed what was left of the tape, with the exception of the bit at the tail end of the silencer.
After a quick 1.5 hr ride, the silencer reached 151F.
For the noise testing, I fired up the beast and let it idle (as long as it could w/o idle circuit). With slow response measuring and about 10' directly in back of the bike, I registered a cool 86 dBA. Not as bad as I thought. I will do more extensive testing next weekend and post the results. Just found it interesting.
Also, I bought some exhaust wrap to do the pipe. Then I'll test the temps at silencer again, as well as noise.
