I bought another 75 433 gpx this week and have a motor question....This one has a hole burnt thru in the center of the mag side piston. I assume it would be a timing issue. I am going to pull it all down and check the variables. I will be sending this all to Delaughter for a complete go thru along with his pipes. Would this be the result of a out of phase crank? Could it be from to many rpms with the stock cdi? It did have some sort of mod pipes on it before i purchased. Any insight would be great...Thanks in advance all.
