Built race spec motor reliability for street use???
I'm looking into a seriously built bike and have some questions for those who know. I've searched some forums and thought I'd ask you guys.
Lets say you come across a motor that has had serious work. Bike is super clean with 3,000 miles on the motor and is:
-Bored +2mm, sleeved and plated
-High grade 2 ring pistons, rods and cams
-High 14:1 ratio
If the bike isn't tracked and has short interval oil changes (1,500-2,000 miles). Will the bike last as long as a reliable stock motor? Before you say, "Obviously not", will it be close? Could one get 30,000 miles out of a motor like that if it was built correctly? Would it be worth spending more on a bike with similar specs vs a run of the mill stock bike? If so, how much (assuming the original build with labor was $5-6,000)? How do you take care of it? As in, do you let the bike start and idle 3 minutes before riding it?
If you'd like to share, how long a motor like this would last in a track use settings I'd also like to know that.
How many miles does an HRC race spec motor last for normal street usage?
As always, thanks for your input!
