Can anyone show me how to modify Gil risers?
 
I have the early style long risers but am still having reversion issues. Does any one have photos of the best way to modify these. I have some ideas but don't need to reinvent the wheel.

Thanks!

You need the later style risers that have more rise at the bend/ The only other option is to weld in an angled dam along the bottom inside the risers.

dgoodman,
What do these header look like. I played with a set years ago and I just extended the inner pipe out the end about 1.5" .. that solved a huge reversion problem. It might help you also.. Just need a pic of what you have now to compare to what I did.. I may have some pics but they would be photos. Would have to scan them if I do have any..

Lets see a pic of what you have..

i have a set of dry pipes i cut to gils specs. the only problem is that they dont have the same bend... so i had to machine wedges. but they are LOUD so im tryinh to get the normal gil style now. you intrested. they are long as hell. i can send you pics. and you name a price. theu were dry pipes in the beginning but since i cut them they act like normal pipes. and i welded a dam in the bottom to ensure water flow over the top of the pipe.

i offered those so you could mabye use them to learn what to do and not worry so much about hacking them up. dial them in and then make the mods to your set
