You will need a 13mm spacer machined between the wheel and the brake disk and a master cylinder that can support twin calipers, You will need use fork legs off,both bikes so the caliper can be mounted on each leg and source twin disk brake lines @wally_escondido has done it , very cool mod
Not too complicated really. You have the 2 fork legs and discs already (1 from each bike). the spacer can be made by any competent machine shop easily from hi tensile aluminium and you need to source the 2 brake lines and the splitter as well as a larger Master cylinder... I dont see it as being any more difficult than what you are attempting with changing your fuel tank etc... it will cost a few $$ but overall it is a cool modification just like @kiffsta said... but each to their own level of comfort in modifying / upgrading their bikes.
Most of the pic's of the GSX250F new show the front brake on the right hand side Look's like the hub would be easy enough to drill and tap to suit the 2nd disc Then using another fork tube with the caliper mount would work, you also need new brake line/s, a brake line splitter for 1 line into 2, and a bigger brake master cylinder. But the only problem i can see is you wont have the larger hole in the bottom of the new fork leg to put the flanged head of the axle through, and wont be able to clamp the axle in the fork. The caliper side fork is threaded and the other side fork clamp's onto the thicker flanged part of the axle.
Single disc bikes usually use 320's so fitting two on to an across might be more effort than it is worth and Sukiman is just feeling his way with all this bike work.
Probably is overkill as the discs are rather large... but it would look pretty cool. I cant see properly from the pics on the Orange bike but it may be the axle setup is the same. I have seen it done before and I was oversimplifying the work required above... (since edited as well). I am sure there are a number of reputable shops around the Newcastle area that could do the work but it is probably expense that @SukiMan doesnt need or want right now Should be a nice little runner when finished though.. hmm Orange... it definitely will stand out
Haha thanks guys but yes a little too much for me just starting off. If I do however want to do it, I would source all the material for it but I would find someone who can do it for me instead, I don’t even like that I have to swap the discs on this bike because I hate touching anything to do with brakes lol. And yes, the orange always turned heads, it also has a bit of glitter in the paint as well haha. I don’t like any of the stock Across colours that’s why I’ve chosen to take the purple fairings off and use my orange ones even though there’s a few scratches on them from my accident, but no cracks or anything so I’m lucky haha. Flywheel puller just arrived, I don’t have a breaker bar so I’m waiting for a mate to come by tomorrow to help me get the flywheel nut off and then all I need is oil and an oil filter and I could be almost ready to go, I’m very excited lol.

I’m really pissed off. The flywheel puller doesn’t fit despite me buying one that I was told would fit my bike... I’m really not happy about this at all. The bolt is way too big and the rounder part is too small so now I’m screwed Sent from my iPhone using Tapatalk
That's what is listed for the GSX250F Across The centre bolt push's against the flywheel bolts' head (with the flywheel bolt loosened a few turn's first) Is that just your picture or do you have the threaded cylinder on an angle compared to the flywheel hub ? Hold the threaded cylinder squarely against the crank and turn it anti clockwise, when you feel it click that's the 2x starting thread's going over each other, do it up from there. If it still doesn't fit measure the thread diameter on the flywheel hub and get onto the seller who you bought it from
So you’re saying to leave the flywheel bolt in like this And then put the flywheel puller over it, even tho it doesn’t screw onto the flywheel, and then tighten the flywheel puller screw so that it puts pressure against the flywheel bolt? Like this? Sent from my iPhone using Tapatalk
Does the large part of the puller actually screw onto the threads of the flywheel? You need to have the retainer bolt for the flywheel loosened otherwise it wont work. Can you show us what the end of the bolt that came with the puller is like... it should have a taper and like a ball end on it.
I’ve already got the retainer bolt out. The large part of the puller barely catches the thread when I try to screw it onto the flywheel. I’m not going outside again but the end of the bolt that came with the puller isn’t tapered, it’s not this one but it looks like this...... I’ve just express ordered the actual flywheel puller made for the Across anyway. I’m pissed about it but I need to get this done lol Sent from my iPhone using Tapatalk
Yes the flywheel bolt need's to be loosened a few thread's (say 3 full turn's out) first before fitting the puller, so that the centre bolt of the puller has something to push against. Once the flywheel start's to come off then you need to take the puller off and wind the bolt out the crankshaft a bit more, or if the flywheel is loose then you can take it off. You say the cylinder section doesn't screw onto the flywheel, but it look's like it does in your picture above ?? It was possibly the chinese one from Jono794 on ebay ? https://www.ebay.com.au/itm/FLYWHEE...hash=item1ea8f7e7ad:m:mIXHwXjOntjlZdfVIlrzFbQ Message him and let him know it doesn't fit the Suzuki Across that it is listed for, and ask him what you need to do to get a refund ? Have you worked out what thread your flywheel has yet as you will need to let Jono794 know
So is the puller left hand or right hand thread? To check this, try turning the puller the 'wrong' way (ie anticlock wise when looking at the flywheel) and see if it grips the threads. If it just slips off, then try the other way to see if it grips. Also check on the good engine to be sure it is the same thread.
If you have ordered this one... it is identical to the one you now have... ie 30mm x 1 RH female thread... so you are going to end up with 2 of them... one a good quality item.. the other from Qld... via China There are not may flywheels that come off first hit... you could try putting some heat on it but it is a delicate balance of how much to put on. I must admit.. I am a little concerned that your mate is bringing pry bars.. I dont think I would be using them in conjunction with the puller... actually.. I wouldnt be using them at all... let us know how you go with it...
Let me just clarify, my mate is bringing a breaker bar, simply to loosen the nut that’s already in the flywheel. Those f**kers are on tight and we already tried to undo it with just a socket and also a spanned with no luck. Yes I ordered this one https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com.au/ulk/itm/131683837869 But if it’s the same I must be doing something wrong but to my understanding the bolt that comes with the puller is what is supposed to be going inside the flywheel, I haven’t seen any YouTube videos or anyone else online saying you have to keep the retaining bolt in the flywheel while you use the puller bolt to push against it, that’s just what I’ve seen. This is the one I currently have https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com.au/ulk/itm/272915235601 which seems to be the incorrect size. I’ve turned it clockwise and anticlockwise and it doesn’t quite screw on properly. I will wait til my helper comes over tomorrow and we might be able to get it done Sent from my iPhone using Tapatalk
Why order another puller with the same thread? Have you measured the thread size on your flywheel to check it is correct ? The pitch also need's to be the same so make sure you check that too Watch this video, it show how to get the flywheel off a similar set up to your's Note that the flywheel retainer bolt is loosened a few thread's before the puller is screwed on
Lol i realise I’m stupid, I’ll hopefully have it all replaced and ready tomorrow lol Sent from my iPhone using Tapatalk
