**WinterMode** V4R Race Bike Project

Custom builds don’t conform to a stock spec. That’s why they call them “custom Builds” and please don’t come on here and tell guys small measurements don’t matter. That just leads to .... poor work habits. Don you have IMA clamps, can you send this guy a measurement so he doesn’t have to tear his bike apart, better yet, got to Seattle and fix this will ya.

Yeah we’ll play around with it. It didn’t help that the Bursig stand is never getting here (7 months of waiting and counting). We strapped the bike to ceiling and put an engine jack down below when we swapped the triple. It was a pain in the ... to say the least.

Before I was hoping to try out shorter wheelbase setting with this triple. We found out that there is no way the thumb brake clears if we pull the triple back with that spacer. So now the triple has became sort of a bling piece. These IMA pieces really don’t play well with the bikes they claim they fit.

You first. Let's see all these "custom builds" of yours. Also if you read, I didn't say that "small measurements don't matter." I believe I said small errors get magnified.

I'm finding with more ownership of a Ducati that Italian engineering isn't the most logical. I mean just the way that a Panigale is put together is mind boggling and makes no sense.

Perfect example is the right fuse box location impeded by this black plastic piece:

Sorry we commandeered your post, Karl. Carry on with your winter project. Love seeing the work that goes into these builds. I live vicariously through them.

LOL, forgot about Vesparacer too

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

There ya go Sparky. Let’s see you stuff. I’ll post more front end stuff if ya want it

Sure. Sure. I have the internet too.

PS This is what happens when you have Zoom meetings all day

Looser, there are a slew of guys on the board that can back me up. Nothing from you huh? I didn’t think so champ

This is all I've got:

Back on target, if you want help fixing the bike I suggest you PM someone you feel is credible and maybe do a zoom call to figure it out.

This is what happens when a guy shoots his mouth off an can back it up. Quite a bit of that going on. I would scratch rac 1 off the list of “people to call” all spit, no skills

Karl, great thread too bad someone hitched a clown car to it, I know you can just open the wallet on these builds but if you were chasing seconds rather than 10ths where would you spend your money?

First thing I did when my triples showed up was check dimensions

Not just the center to center... the rest as well

Only thing I found that I didn’t like was the steering stem. They machine it down to reduce weight and maybe help with air flow but they went a lil overboard and it has to be perfectly centered vertically and even then I’m not sure the inner seals are gonna hold air. Once again dudes problem is not the trees. Symptoms would be different if it were

Yeah I am Ed, and I am sitting here waiting for the cam timing tools that he is gonna send me to show up so I can see where the factory put the lobe centers - Smoked

Plz send that .... bro

@KarlKani lemme know if you wanna sell that beat up fuel tank. Mine just sold : )

Guess he has us both on iggy @Paul G lol

Hope you aren’t saying I hijacked the thread? Dude put some trees (same ones Karl used?) n some rotors on his bike and is having issues. He coulda started a new thread sure but no biggie. Least not to me : )

While on the subject (the forks/wheel/
rotors/spacers/ etc thing) I have a question:

While doing all that crazy stuff to my front wheel I noticed that with all the oem parts the wheel bearings end up loaded when the nut is torqued. It’s like Ducati didn’t know how wide the bottom of my fork was when the made the spacers. Why would they load the bearings like that??? Do ball bearings need side load??? I would rather have just enough squish so that the wheel can’t move side to side but no side load. Thx in advance

Don its not the advice, its bunfight over who is genuine or not that seems to infect a lot of discussions. I'm not an engineer but the IMA triple or rather the offset wheel prob requires the Hansel and Gretel solution, when lost go back until you get to the point where you really know where you are. Then proceed. No need for a major 3 page sidetrack. A really simple way to check the IMA's would be to insert the forks into the lowers all the way then slide the stock lowers onto the forks. If they fit then the problem is elsewhere, no? Direct reference eliminates measurement errors.

If the forks were off the bike sure. Which they may be now? Dude hasn’t responded since it went a lil sideways. I never measured the centers just laid them on top of each other

I am asking why the wheel bearings are seeing such a side load? Karl stated (pages ago now prolly lol) that he barely tightens the nut. I am making spacers for mine but want to be certain I ain’t ...... up making it so the bearings don’t see that load. My left leg is 060 wider than it needs to be WITHOUT the washer. Maybe I am a ...... and they need that crush? Hey @endodoc...

Well it’s more like now stuck in a perpetual u turn than sideways. This stuff is so simple it’s hard to process that there is actually a thread on it. First is the erroneous assumption that something is supposed to be a certain way. This was my point on the different triples. Unless absolutely stated to be a “drop in replacement” for an existing part, the manufacturer can make the dimensions whatever they want. To then post that the manufacturer “screwed up” is nonsense.

I have in my possession 4 different triples for the 99 platform. The center distance of all of these clamps is different. If I’m going to select/mix and match manufacturers components to build a front end, I most assuredly assume that somewhere in the engineering of the assembly that I’m going to have to do a little massaging to get all of these parts to work harmoniously.
It’s just a given.

Now this completely assumes the “builder” knows WTF they are doing going into this which could be an entirely different conversation. So in conclusion, there’s nothing wrong with the IMA clamps. IMA didn’t screw up. They make an aftermarket part. It is entirely up to the buyer to determine beforehand if the components that constitute their assembly will be compatible and what the necessary steps would be to ensure that if it’s not a simple bolt on replacement.

If the buyer didn’t do the diligence prior to purchase, then as Don said, easiest way to determine compatibility is to compare the clamps using the fork legs as a jig. If it’s off and you don’t have the skills or resources to modify to fit, send the parts back. Pretty simple.

Don with regard to the front wheel bearings, they are not “laterally loaded. There is a center spacer between the bearings that has a “no L load” precision sandwich. So if your question “am I causing a radial load between bearing and it’s case, the answer is no. It is impossible to mess this assembly up. I surmise I should add “for most people

Guess I should add that the only critical spacer is the “clutch side” of the bike as that spacer is a dead stop from the bearing to the fork bottom. The other spacer ideally should allow the axle (big end) to fit flush in the fork bottom but it’s not used for wheel alignment. If it’s a bit short the axle protrudes a hair more on the nut side of its too long the axle protrudes a hair in the big side.

I am so smoked. Of course the center spacer prevents side load when nut is torqued duh. Thx

That bit about the dimension of the right spacer not mattering can’t be right tho. If I took .100” off the left spacer and did not add .100 to the right spacer the axle would bottom out in the nut and nothing would be sandwiched

Guess you could add washers but this is a Ducati. No double washer allowed : )

The right spacer does not matter. It’s a floating spacer (length wise). It has nothing to do with wheel centering as it bottoms on the axle shoulder (big end) and that end is retained by the pinch bolts. It ends up wherever it ends up when the axle is installed. The right side spacer is the same diameter as the axle (big end) and slides right through the fork bottom hole. It is not sandwiched between the fork bottom and the bearing like the left side.
