Suzuki 2 Strokes

Here are specs for X-6 expansion chambers that were used for drag racing by my Father and I.
I hope my dads knowledge will help someone who wants some chambers.
I will also upload a pic of some mounted on a bike raced by me in the 1970's when I was a kid.

By the way I also have specs for T-500 that I will upload as soon as I can draw a diagram.

Thanks for sharing

Thanks for digging up those dimensions. That is the Race Kit chamber described in page 3 of Suzuki's Bulletin #4 dated August 9, 1969 which has found itself all over the web but usually without any reference to where it originated. Bulletin #3 is Motocross/scrambles and #4 is road race and flat track. #5 issued a few days later was to fit larger 28mm carbs.

For drag racing that pipe was probably OK. I'd hate to use it on a street bike though

I know that dad got the specs from Suzuki, Probably through a friend who was a Suzuki dealer at the time. I agree that they would not be good for the street as they are VERY loud. With the stingers replaced by silencers, maybe.
