HI T.G.,
 I have a set of those manifolds still mounted to a POPS ported head. I could take some good close up pics and send them to you.
 I found a odd set of VM27 flat slides that I modified to fit the manifold spacing. Just not ready for assembly. I want to find a POPS transmission for it.
 I would like to try and reproduce the manifolds. They are all the same(one casting). I have a pic now, I just can't figure out how to post it.
 I posted a pic the other day, but now, when I hit the post button after adding the attachment, it says it can't find the page. I'll try again!

Wow! would definetely want to see that! check your messages, sending you my mail address, send me the pic an I'll post it for you.

Was the head ported by pops?



Actually i checked and it is closer to quarter turn.
What type of racing are you referring too..? If you mean circuit racing, i have ridden a few race bikes {FZR 1000, GSXR 750 and so on, on the track} and none had the shorter turn throttle.
Drag racing is a different thing altogether..

I meant road racing, my VM set up is about 100 degrees to WOT and I have problems giving it full throttle at times. modern bikes ( i own also 750 and 110o GSXR's ) have CV's or injection and throttle effort is much lower than with slide carbs. Still, even those bikes repsond better with shorter twist throttles.
