Extend Own Swingarm

[TheBansheeMan86]

i plan on extending my own swingarm and was wondering if anyone had any tips or tricks on how to do it best. i plan on doin 4" longer, and will have new chain/sprockets and a brake line (even though 4" doesnt need one) i have access to a metals shop, i'll be MIG'ing it, and also what grade/size steel to use? anyway, any tips would be greatly appreciated.

i just extended my brothers swingarm 3 inches. i went to the local metal yard and bought some steel the same size as the factory side rails. i think it was 1 1/8" x 2". then i cut the swingarm right behind the rear cross brace. make sure when you cut these that the carrier is still on. i never took it out the whole time i extended the swingarm. it makes everything stay straighter. cut the 3" extensions and tacked them in. once you make sure everything is straight you can weld it all up. i recommend some more bracing as just adding those is doesnt make it very strong. i will get some pictures up here in just a little while for you.
