So where do you put them Bill? Any Pics? Any suggestions on hardware to use?
No photos, sorry - you'll figure it out.
Put it on the carb and note how far the carb sticks in, then go just beyond that.
Make them project up and out at about 45 degrees.
I always used cut-off 750 main jet holders, because we had a lot of them around, and they accepted the normal 5mm screw that caps off stock Honda manifold taps (like on the Fours, CB200/360, etc.) when not in use.
I think a lot of jet holders and stuff like that are that same thread size.
I just make sure it doesn't project into the airflow any - I always just epoxied them in.
The hole you drill doesn't have to be perfect- in fact, if it's a little smallish and irregular you actually get a better glue joint. I suppose you could even use plain ol' silicon, I wouldn't be afraid to use it.
I'm planning to make up a couple of sets soon, just haven't got to it yet, with all the travel and everything.
