I'm wondering if anyone has some good info in regards to coating a 2 stroke pipe with Jet Hot or HPC. I've done race car headers and exhaust but don't know that I've seen it done on a dirt bike. I'd like to have the low maintenance that it offers but am wondering if it would affect performance in a negative way. One of the main reasons we do it on race cars is to keep the heat in to maintain the velocity to scavenge the cylinder well. Will this scavenge a 2 stroke cylinder too much and cause a loss in performance? I would suspect that different wall thickness pipes would also react similarly although to a lesser extent. Thanks for any insight!
