Just to put my 2 cents out there. I am selling the 74" & 80" 13 fin repo cylinders too, in different configurations. I have thoroughly gone through these castings & have found the following :
- the base flanges are 50-60thou thinner than the stock base flange (i.e. 0.450 VS 0.500)
- the intake & the exhaust bores have some core-shifting & need porting to flow anywhere near original
- the exhaust external airflow also needs the flashings cleaned up
- overall the external appearance is a little rougher than Harley, but for the price, we are lucky to have them.
Future testing :
1. We will be testing to see how well they shape up when using 1 original cylinder & one repo cylinder. If this test is good, we will be selling individual cylinders.
2. We will be doing K-model threads & intake adaptions to these cylinders to see how well they handle these performance enhancements. Will post results.
