The engine temp seems to be normal at 160 degrees. The guage never varies at all. The possible problem is the bottom of my exhaust riser is cool to touch gets pretty hot at the top of the riser then cools off again at the bottom before it exits through the bellows. Is this normal or do I have a clogged up riser??? Thanks Kellyriser.jpg
