6400/7300/7900 muffler on a 7910 cylinder

My friend has a Dolkita 6401 that he is going to be putting a
7910 p/c 'kit (with the new top cover) on. The exhaust port
outlet on the 7910 cylinder is larger and differently shaped to
work with the funky SLR muffler on the 7910. Anybody here have
experience running the old style muffler on the new 7910
cylinder?

I've done it on a few that were converted. Open the factory
muffler up some to port match better. Don't go crazy or all the
thick part of the muffler will be gone.

most people that i have run into just bolt it on and go but a
little port matching would surely help. IIRC if completely port
match the 7900 muffler to a 7910 cylinder the thick
reinforcement plate on the flange of the muffler will be gone

Sounds good. We won't go crazy with the port matching. Thanks
for the info.
