Overheating

[crazyratt]

I have a 1984 200x. I have it bored out to 66.46, so i know I have very little cylinder wall left. I have every think pretty much stock- just a cobra exhaust and a k&n filter. I run valvoline 20-50 racing oil in it. What kind of overheating issues should i look for? How long could I run it? Already ran it real hard for an 1.5 hours, no problems. Anybody got some insight.

With slightly more displacement and the exhaust and filter your engine is "breathing" better. I would make sure you are jetted properly on your carb, the thing you don't want to be is running lean (air to fuel). A lean condition is a hot running motor (not in a good way). Do a search on jetting and you should come up with some good info.

I would think as long as you have it jetted correctly and its running good you shouldnt have a problem running it for longer periods of times
