Brazing a mount to the frame would be better . . .

Tig welding would probably be better than brazing, but the equipment is more expensive and it requires more skill.

Would not drill through the frame without welding in a support boss.

Here's a link to the thread that contains steell's above post, plus other advice in this regard.

Good Fortune!

Patton.....the holes would be on the tube under the seat ( 3/8"). Would not think thier is any stress from the engine.
Are u saying it would crack from vibration over time?

Also how do I measure for chain drive lenght? front to back sprocket

Can't you bend it all the way around the frame nice and tight and then bolt the strap back to itself?

it is the stress from the rear shocks working feeding through the subframe into the backbone tubes that would cause you problems.not vibes from the engine.

drill a 5/8's hole and use some 1/8 wall tube cut to length and weld it in.
now it is stronger than it was to begin with.

p.s. a piece of string wrapped around your sprockets can get you close on length then a little math will tell you how many links you need.

531blackbanshee......not using duel shock going mono.
sbc1320.......I could but in case i need to remove the paint would get damage by bending the metal.

what about how to measure for a chain?

second take.......
work on the battery mount.





pis of finish mount with electrical components mounted

front brake master , lever and left side lever from china....cnc cut nice componenets will see how they hold up

so the string goes around the front to rear......measure the lenght of string into inches then what?

diviide that by the chain pitch (5/8's for 5 series or 3/4's for 6 series)and that should give you the number of links.

the mono shock will remove the forces from the sub frame i was refering to.

but,
just drilling holes through tube to mount anything is poor form and the area where the hole is will fail if it is going to fail anywhere.

some tabs welded to the side or bottom of the tube vertically (hangin down) would give you mounting points and not compromise the tube.
thats my .02 fwiw,
leon

p.s.

in case you need help figuring out your offset.

tabs.....yes
mind was set on welding the supports to frame originaly

thx

happy to help sir!

leon

having a hard time finding a 1/2" offset sprocket.....any one can till me where to find one.
if not thinking of using a 170mm rear tire with a 3/8" offset..
any thoughts
thx
