I knew you would notice a differenceGot this ignition installed today. Definitely seems to have helped up top. Seem like the bike is pulling a lot cleaner.
Also note,the NGK cap is not needed as this wife cap already accepts the terminal nut. So all the koso 4v head users just need to install a terminal nut to your spark plug. Also; the mount holes do it line up and seem to be for 8mm bolts instead of 10mm. A simple bracket needs to be made although I just zip tied mine in for the test.
