not sure if rev was talking about me or the silver ke70 dude,
but i made one of these kits about a yeah or two back aswell, it ran ok,
the signal is backwards but not a big problem, mounting it was easy, and cutting the dizzy stalk was not bad,
i ran that sucker for about a month or two, in the end i scraped it and went DLI, cos it was a cleaner look,
note' on that kit the key way for the dizzy to sit in(the small round piece next to the bolt) does not have a locating dwell, you should put one in and you should be able to use the second hole on the exhaust cam as the locating hole, that way it wont spin round and mess up timing,
also for the price of that kit listed above, its cheaper to go DLI/cdi ignition and would look better,
go for it, its easy to do and better then chopchop of firewall
