pullback bars from scrap.

PostAuthor: oberonspacefruit » Tue Jan 16, 2018 3:19 pm

I thought Id have a play about with the b ars on my 750, it had a set of drag bars which i wasnt happy with, and they made the brake fluid resevoir sit at the wrong height.
Got 4 tubes from the local scrap yard, about 33mm with a 3mm wall, and 2 90 degree bends on each.
Cost virtually nothing so nothing to lose.

Ive chopped 2 hockey stick lengths with my chop saw thats fitted with a steel cutting disc.

2 bolts with nylocs are arc welded into about 1/2 inch of tube, to fill the gap between the 7/8 bar tube and the big fat hockey stick type rusty tubes......technical I know......

Rough fit for positioning, but maily to check the centre distance, ive done away with the risers, but theres still a bit of give in the rubber mounted sleeves. Its 103mm centres from memory.

made a centre supprt/spacer to stop the individual bars from twisting in the triple trees. cheap hole cutter takes a while, i did the second with a grinder, by eye.

its 65mm internal between bars.

pieces of 7/8 sleeved up and inserted into the bars. arc welded roun the lip and ground away, then hit with draw file.
Im not going crazy at this point with appearance, as they may end up being chopped again.

At first, I thought “those are too thick”, until I saw the 7/8 pice welded it. :GJ:

i saw a set of apes at my local bike club that were built on the same principal. means you can use any size tube within reason for the main bars and only need to stock a bit of 7/8 for the controls, unless of course you make those too. I think the problem will be them being either to close to my chest, or the cables needing lengthening. it came witj some drag bars, so the existing wiring was cable tied up, but ive not attempted to measure it yet.
