Hey guys, so i installed the trail tech cht today and I'm curious what a safe operation temp would be with a bbk? I did a bit of research but theres so much conflicting information.

I start backing off at 360F. 375F is when I let off completely.

I've had two buddies who felt sudden power loss, backed off the throttle, and when they looked down at the gauge, it was reading 400F. Luckily, both their bikes seemed to run normal after cooling off. Probably seconds away from disaster.

When my bike runs up to 375F you can smell the oil odor coming out of the breather. One long ride where the bike stays close to 375F, and there's a good chance my synthetic oil will come out with a viscosity like water.

I figured 360 was the high end, but what should normal operating temps run around. I've seen 205-230

If you're running a stock cylinder head and stock throttle body, I doubt you'll run into overheating problems. Especially with 17/32 gearing. Going full throttle up a hill in 3rd or 4th gear is when you want to keep an eye on your CHT.

  1. If you're running a stock cylinder head and stock throttle body, I doubt you'll run into overheating problems. Especially with 17/32 gearing. Going full throttle up a hill in 3rd or 4th gear is when you want to keep an eye on your CHT.
  2. I'll keep that in mind. The bike is built to cruise speeds. No tracking it or anything like that yet haha
