914 Freak! Group: Members Posts: 17,150 Joined: 4-January 03 From: Antioch, CA Member No.: 87 Region Association: None	The cost of aftermarket throttle bodies is way up there, the bottom of scale we have the CB Performance units which are about $250 each and the rest are easily 2X that about..... so I swung by the motorcycle salvage yard in Fremont today and picked up these beauties (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) 45mm at the butterfly....they taper down to 42.5mm at the bottom... includes a nice TPS and injectors...I doubt the injectors flow enough, but who knows, I'll find out once I get the specs.... no idea of what bike they came off of yet.....price was $125 top view: Attached image(s)

Long term tinkerer... Group: Members Posts: 1,879 Joined: 7-April 03 From: Lyons, CO Member No.: 529	Hey Mike, Those Wakisaki throttles look great! Let us all know how it works out! With my workload and the imminent expansion of the family unit, I didn't have the time to engineer other TB's to fit, so I broke down and bought the TWM's. But, the good thing is I wound up paying a little less than I would have paid for the cheap cast throttles from CB-Perf. If anyone's thinking of going the way of ITB's, look a the big pony car shops. They deal in volume, so I guess that's why they're more than 30% cheaper than TWM... So, the project continues (slowly), TB's are on the way, and I guess I'll be ordering the MSII when it's available... This is going to be the most non-stock looking, stock motor in a 914... -Josh2
