Be careful with modifying the swingarm..... There's a couple YouTube videos of the carnage/aftermath of guys who tried shortening and modifying arms on Busa's
YIKES.....
Somethings I'm down to modify but when it comes to the chassis and essential parts that keep the bike upright and in 1 piece I'll leave it to the professionals
Ozbooster should know what stick to use, he has lengthened his swingarms for use at LSR events.
I've used both 4043 and 5356 wire
And you welded my bung hole tooLike you,I also weld professionally
