s1 swingarm.need help, info on down pipe fittment, trade, sell, more? ty. steve

ty, you have first chance. but I still need info on what it fits,
and why it has such a large collector. can it be used for kz1000/1100.J R GPZ
are ther any head pipe sections for it out there?my kerker has 1 5/8
os down tubes,LOOKS LIKE KZ650, collector is exellent shape.
downpipe has some pitting .
my trick on finish for my kerker, is jet coat, sanded and painted. has lasted for 10 years in Florida east coast.

what bike is this going on?
i can measure the primary spacing on a 900 for u tonight.
my yosh measures 30.5" x 1.35"id /1.5"od for all primaries.
collector = 2 9/16" id (2.75"od) x 30" long.

i have a few spare pipes.
i have not seen a Yosh with that shape of silencer before . they r usually the same diameter all the way down. that shape reminds me of the Bassani shape.
here is a pic of both.

Is that a genuine S1 you have?

I wish, it is a 1983r2,withs1 replica parts, swingarm, lower tree, rearsets
oil cooler.these are copied from a real s1, not zrx stuff, from Paul Kondraki.
My parts are pictured in my old posts.
and since you posted larry, can you tap/weld my oil junction for an8 for my oil lines?Ty, anyway heres apic.steve

the with of the primaries at the head on a 900/1000 is 14" (outside to outside)so that pipe is def. from a smaller displacement bike. Nice pipe.
