DUCATI WHEELS ON A XJR1300? Yamaha XJR1300 Shoogly Shed Motors After more than a year, I've finally finished off fitting the Ducati GT1000 wheels... but yet another EXPENSIVE issue crops up!
First job has to be to set the wheel central in the frame and aligned with the front wheel and fix it in that position Second job is to align the rear wheel sprocket and therefore the chain with the engine sprocket. you can get away with spacering the rear wheel sprocket off the carrier by up to 10mm or maching about 5mm off the back of the gearbox sprocket Third job is to fit the disc (brembo on Ducati wheel) and then align the centre of the brake caliper with the centreline of the disc, this may involve manufacture of a bespoke caliper holder - 10 or 12mm aluminium plate should suffice for that. It needs to be in that order a) for handling, b) for ensuring the chain can safely deliver the power and c) because a bespoke caliper bracket is a lot easier to make than a cush drive for the rear sprocket
It’s not ideal, but honestly… the build just got even more interesting as to the RU-vid content? Very little solace I’m sure, but half the fun of watching is seeing how you fabricate your solutions. I am relegated to parts off the shelf and lack the skills and patience to do anything like what you do. Artistry in action and problem solving issues is good entertainment. Sorry about the delay and difficulty, but looking forward to more solutions. I think I’ll pick up some merchandise to try to help. Cheers from Colorado, USA Euan.
Good work i had the same problem on one of my build, just make a new caliper hanger from a 1/2" peace of Dural cut out and file by hand the only awkward bit is the spindle hole drilling but you could get an engineering firm to do that if you dont have the facility to carry it out yourself then make make some spacers to centralise it.
Nice work, Good to have lathe in workshop, speeds up aligning and making custom stuff! I struggle with same issue on my CB750 build as I want to put way wider Kawasaki rim on it...
Big option in my opinion would be either the brake and carrier from the duke or use a spacer for the disc and see if the oem version of the xjr would fit
Maybe you could make an adapter for the brake disk to compensate the offset, and maybe to fit a disk with the correct diameter. I made something similar to fit spoked wheels from a bmw f650gs to my bmw g310gs. I had to compensate a 10 mm offset at the front wheel!
I don’t have any experience in the availability of parts diagrams for Ducati. But. If you can get a hold of a parts diagram for the GT1000 , then there is a chance to start x ref the brake parts. See if the caliper hanger was used on any other model of Ducati. If you can get a hold of one, beg, borrow, steal to test fit?
Just one other thought while watching / listening. The front and rear wheel need to be on the centreline and then chain alignment adjusted to suit? I imagine you are going to get some interesting handling if the wheels are not inline 😬
Oh no Dude! Noooo…. You need a few bottles of good Scotch - I say ‘good’ be cause you want to localise the areas of hurt (i.e. not your head) - or a few bottles of a ‘big beer’ whatever works for you), a tub of Vaseline, and to relax - not tense - your sphincter … 😉
@@ShooglyShedMotors I needed a crank pulley holder for my car, but I couldn't find it in the uk and would've cost over 400 quid from the US. I found a machinist on fb marketplace, made a simple drawing, got a piece of steel and he milled it to dimensions. It cost me 110 quid because the steel I gave him turned out to be partially hardened, which made things a bit difficult. A caliper mount isn't complicated ad will be a lot cheaper to make once, than getting a custom disc regularly.
Couldn't the Ducati swing arm that goes with that wheel be made to fit the XJR, then all of the parts for the Ducati like the spindle, disks and callipers could be used?
