Well, and now I'm really curious. Has anyone on this list tried a system
without the crossover and NOT been able to make the bike run great? Or
even better, chime in if you have been successful in removing the
crossover from the equation.

Dear Hacksaw

If you are going to cut up your new header pipes you might as well use
the
old ones.

If I remember this correctly A crossover close to the exhaust port will
increase flow (less back pressure) having the same effect as longer
velocity
stacks. Theoretically giving you more low - mid range grunt.

The exact location and dimensions of the velocity stack and pipe could
take
some trial and error. BUT the Del'Orto carbs have all sorts of
adjustablity.

I just got a new/old set of header pipes to replace my NASTY ones and
have no stock crossover.
My question is:
Would there be any 'benefit to' or 'problem from' having a crossover
welded into the header pipes across the front of the engine?
My thought is to use something just under the header pipe diameter.
Thanks,
Hacksaw
