My 15 year old son found a 1997 Indy 500 that Sat for two years outside for $400. He negotiated a deal with the guy (a family member) to see if he could get it running first.
He and a buddy got it to our garage and when they tried to pull the cord the engine was froze up. They asked for my help & I thought - stuck rings, so we put some lube down the cylinders. After a time that freed it up some but it was sticky & the lower end made squeaky noises.
So, we pulled the carbs & exhaust & filled the lower end with two stroke. After a time I spun the clutch by hand & it was completely free!
So then we flushed the block and did the fresh gas, oil, carb cleaning thing & put it all back together. Compression test 122 both sides & good spark.
Pulled the cord & it fired on the first pull!
So my question is this - with the crank bearings formerly froze how much of a ticking time bomb is this engine? Has anyone ever unfroze bearing & had them last a decent amount of time? My son's friend is looking at buying it & I said it could run for 10 miles or 2000 miles but I don't really know.
He put 10-15 miles on it last night. Seems to run great.
Thoughts?
