My JP Eagle.
It is shown that the combustion is more spread on the piston and did give a better performance. The question is what is legal to modify....
As I told here before the cranktiming can do a lot, but if it is not alowed to modifi the crankshaft and they do inspections you can always alter the cranktiming by modifying the crankcase in the hole under the carburator, they will never inspect that
I have read through this whole thread and have learned tons of info. Thanks to every one! I have a question about these lines. Does the one big line with the two little ones go over the exhaust port is it just one big line over the exhaust port and are the other two big lines needed? Thanks.
