If one side is touching the outside of the caliper and the other is touching the inside then your wheel is simply not centered based off the wheel spacers you have and that is an easy fix.

The axle sticking out is not an issue except maybe aesthetically. That is a result of the wheel spacer’s dead stop between the axle shoulder and the bearing. So if the wheel and the fork are the same (before IMA) and the wheel spacer is the same then all indications are that your IMA clamps are narrower than stock (axle showing). This will require a mod to the wheel spacer or spacers to center the assembly.

Regarding you assumption, understand that 90% of guys running aftermarket clamps are also running aftermarket wheels and spacers and that there are additional spacer kits available. You start layering in different calipers and rotors and you now potentially have 4-5 different manufacturers of parts in that front end. It is generally universally accepted that the more you mix the more likely you will be doing some custom work. I have personally made wheel and sometimes rotor spacers for every bike I have put together using aftermarket parts and that’s to get the wheel and rotors dead nuts which is probably overkill but that’s me.

If there is a 040 washer under the nut remove it and see where you are

If wheel still has to go more to the right there are 2 ways to do that:

Make new spacers (thicker left thinner right)

Or don’t use the nut to locate the wheel (like Karl is doing)

Don what good is removing the nut washer on the outside of the assembly going to do except move the nut closer to the outside of the leg?Additionally Karl is running a FF axle which if it’s the same setup as I have has a threaded sleeve that you leave in place so you only have to loosen one set of pinch bolts then screw the axle out. So Dons advice on the axle is a bad idea. Not at all the same setup. The front wheel needs to have proper spacers.

Yep

My bad

Adding my 2 cents, assuming you aligned the fork legs properly before tightening the pinch bolts?

LOL that’s one of those “first on the list” things I assume was obviously checked so it wasn’t mentioned but yes good point, “check that first”. I know better than to assume anything these days.

I guess the other thing could be that the IMA triple are out of spec. Maybe take the stock triples and IMA ones and thread the forks through the top triple to check the spec. Then repeat with the bottom triple.

The wheel is slightly left for some reason

How can trees cause that?

LOL out of spec, who’s Spec? There is no standard. This place is crackers

Well the calipers bolt to the forks and the trees determine where the forks end up so center to center has got to be same as oem if you are to use oem wheel and oem offset rotors

No spec just a dimension

They are cnc and have Italian quality control. What could possibly go wrong : )

From my understanding he's using stock wheels and stock spacers. The variable is the IMA triples. These are things that could influence wheel centerline. Sounds like he's trying to reference to the stock wheel/spacer spec. Therefore the IMA triple should adhere to the stock triple spec in order to fit up properly. If the IMA triple fork holes were off by <1 mm (maybe it shifted slightly during machining), it might pass QA since it's such a small deviation but the effect is magnified once all bolted up.

Or the rotors are off. Or his forks are bent. Or it wasn't assembled correctly.

Exactly this. I have no reason to believe a product advertised for my bike would have measurements different than stock. Especially when it’s not specified that way. That’s why I’m asking if anyone else ran into this problem.

If this is super common, then it sounds like keeping the wheel centered is all that matters. Maybe. But still I think I’d say IMA messed this one up if they are out of stock spec.

Do you have the oem triples on hand to measure?

Yeah I do and I thought about comparing. It’s just super annoying now I have to waste my time to pull it off. All of these pieces are very difficult to position right. The thumb brake, which they again advertised for fitting my bike. Barely fits with the stock and race fairing. I guess it’d either be new spacer or wasting an entire day...

Damn. Yeah that blows.

Bro...

If it were the trees the rotors would both be rubbing on the outside or would both be rubbing on the inside

period

If it were me... I'd loosen all bolts on the IMA triple and give everything a wiggle to relax the system and then gradually torque up the bolts in the pattern IMA specifies just to hand tight so it doesn't fall apart when fully assembled. I'd then clean all surfaces where the spacers and wheel interface. Then I'd dry fit the wheel and barely seat the axle and see if you get the same alignment issues. If the alignment issue is still there give the lowers a wiggle to see if it works itself out. If it doesn't fit that way, then there's something off. Send the IMA triples back and call it a day.

Unless you're a top level racer, you won't notice that much of a difference and it seems like these triples are more trouble than they're worth. Revert back to stock. Your time is money!

Don, I told you, he forgot to do the wiggle. Easy fix.like I said, I plan on making spacers “every time” I build a front end and I end up making them “every time” this is a 20 min fix. Good luck man.

I wouldn't be surprised if endodoc and Don14R are one and the same. 2000 posts with absolutely nothing to say.

I'd hate to have a front end built by you then. You shouldn't have to custom machine spacers for each build especially if they adhere to OEM specs. I believe what you're saying is that your forks are misaligned or your wheel is misaligned.
