Just did an engine upgrade on a 103 engine to a stage 4. Jimmy spent some time explaining and going over the procedure with me and discussing the the options, in the end he selected an excellent upgrade ordered the parts then turned my bike over to Red. Red took time to build the engine correctly, wow does that motor run great, So glad Quaid Bros. realize what a great team of top Harley employees they have (Employee: Jimmy Todorovitch, Red Barton)
