Hi Everyone.When I was growing up we lived on Stratford Rd in Winston-Salem,NC.I can remember seeing brand new Big Red trikes in front of the Honda dealership.I used to dream about those things.Well,here it is 35 years later,and i finally got one.LOL.It's a 1985 model that I picked up at an estate auction.The factory rear tires still had the teets on them,although they were severely dry cracked.It had an exhaust heating issue,as there was plastic damage on the front and right rear fenders.Fortunately,new plastic was purchased in 1994 and it was still in the wrapper.The battery was dead,gas was stale,and it would only run on choke.So I had some work to do.I replaced the rear tires,installed a new battery,rebuilt the carb,replaced the air filter,and changed the fluids.It runs and drives really well.But I am still worried about exhaust heat.What are normal temperatures for an ATV of this size?Here is what I am seeing:
250 degrees at the spark plug hole
750 degrees at the header bend
500 degrees at the bend near the airbox
No backfiring.It may be a bit cold natured,but after it warms up it runs good.I don't really have enough seat time to tell if it's down on power or not.I installed a Moose Racing carb kit,but I reused the factory jets.(After cleaning them with a torch tip cleaner.)I replaced the needle and float with Honda parts.Should the exhaust temps worry me?Thanks everyone.
