I am picking up a set of '02 f4i forks to swap onto my '02 919. I have searched around and found lots of great info about using F4i forks on the 919 and the only real downside I see is that you can't reuse the 919's front fender.

I plan on breaking the forks down and swapping new oil and springs. Since I will have the forks broken down I want to mod the f4i forks to accept the 919 front fender. I have 2 different options in mind.....

Option #1.
- switch the F4i fork bottoms for a set of '06 919 fork bottoms. Not sure if they are a direct swap or not? I have a full set '06 forks with bent tubes to salvage any pieces off of that might be required.

Option#2.
- have the tabs welded on to the F4i forks to accept the 919 fender.

I am hoping option #1 will work. Since I have the tools and parts on hand already.

Any input or advice is appreciated.

Thanks,
Ian

ya your not going to be able to switch the bottoms, they are completly different internally... and the F4i bottoms have the one main factor for swapping to them... the compression adjustment lies in the bottoms.

in all honesty just go with an F4i fender... it will cost much less than having stuff rewelded.

Thanks for the info. I forgot about the compression adjustment. I will just go with the 2nd option and get them welded. I should be able to get them TIG'd for beer money at work. I may go with a modded F4i fender if it comes down to that.

I also have a question about spring choice? Do I just add the extra weight of the 9'er onto my weight when ordering f4i springs? I don't want to confuse the spring company with to much extra info.

Ian

hmm... not sure that would make sense though.

PM 'd you details and feel free to post it if you want.

Thanks man, great info!!!

I've not done mine yet, fitted my modded F4i forks that is, and am pretty sure that all that's needed to mount the 919 fender, is new forward mounting tabs.
The F4i rear tabs for fender mounting are supposed to be OK as is. The F4i used low mount front tabs, while the 919 uses hi mounts. The 919 fender should sit a little lower, or so I recollect from eyeballing of things during the winter. I've seen pictures of 919 fenders on F4i forks, so I know it can be done. zaq123 had a good fix for the sinful looks of the F4i fender, but I still like the 919 better and am sticking to it.

Very very correct, and proven by physically examining and comparing.
You can not swap F4i lowers over to 919 tubes and cartridges.
Too bad, as my idea was to buy bent F4i forks super cheap, and just use the lowers.
The experiment was inexpensive.

I did the f4i swap, and just bolted only 2 rear fork mounts to my existing 919 fender. You have to shim the inside of the front with 2-3 layers of double sided sticky tape, but it leverages nicely. as long as the back bolts are pretty tight the fender is mounted pretty solid.

This is not a 140 mph solution.
I dread to think of the consequences of the fender pivoting upwards in the middle of a top end blast.
If someone does not want to weld or has no such access, a strap can be formed from strip steel or aluminum to tie the hi 919 front fender mount to the low front F4i mount.

Alright finally got this done today. Fresh seals/bushings and oil, Race-tech .095 springs, powdercoated fork lowers and some custom stainless steel fender brackets. Now onto the back & install my shiny new/used 420 progressive rear shock and set everything up. So excited to have some adjust-ability on the old '02!

I also picked up a second set of gently tweaked F4i forks today, had to replace one of my fork caps from a little PO mishap. Will be dismantling these dampers and looking into re-valving, like we talked about in another thread.

If anyone needs some Fender mounting brackets let me know, I can make these pretty easily and they look pretty clean if I do say so myself.

Nice! The fender brackets do look good!

Thanks! They are .032" aircraft grade stainless steel, very strong and should outlast the rest of the bike.

Great job Ian!

I WANT THE FENDER BRACKETS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!


lol. seriously! Make me a set. I'd LOVE to finally be able to mount up my 919 fender onto my f4i forks. Let me know how much it'll cost. Thanks!

PM sent......lol.

GROUP BUY! I'm in with PVster if you do make em!

*edit: If its cost effective on INTL shipping, you can ship them to me and I'll ship him his.

As long as the brackets don't say "Ohlins" I think I can trust Andrew....

Nah if they said "ohlins" i would have to charge $200 for them, and gear up for a lawsuit. Brackets will be $25 shipped anywhere in canada or the lower 48. Let me try and replicate a few sets, then I will post up a FS:Thread.

I can do that, they should be pretty cheap to ship. Let me look into it and get back to u guys.......jesus u guys are fast!

PVster wants his in pink. If not, magenta or lilac

I was just going to stamp the word "queer" on them. I can do Lilac.....

You mistook us, Andrew wants "queer" stamped onto his. Lilac works for me

Actually I should just take PV's and leave them out in the rain for a week, then throw them in some mud. That way they will match his bike perfectly!

Paint it a different shade of black than what I currently have on the 919 (at least 4) while you're at it, thanks!

Heyyyy that would match my bike perfecT!!

Actually, just wrap PVster's in a condom. Then they'll feel right at home

NO MEANS NO!

Do we really have to keep reliving this condom bike thing?

BTT: How them brackets coming?

+1

Got the stainless bent up. Just need to file them down a bit and pick up the attachment holes. Should be ready by weeks end. PM's sent.

Sweeeet, PMed back

Ditto!

Where the heck is Mcromo?! Thought he'd be all over this

I don't know? I pm'd him about it and never heard back.

That particular PM must not have got to me.
Anyway, I'm going for welded on tabs instead.
I only got out for my first ride on Sunday.
I need to get off my butt and get the F4i swap done, seeing the internals work was done last year !
I just need to fab up the tabs, get them welded on, fit the super trik only set in the world 20 mm extended fork caps, and change my internal preload to 10 mm from 14 re the now 0.95 spring set. (was 0.925)

Screw that mcromo, just get a set of brackets and save the tab welding for next winter!

I am making you a set anyway & sending them in the mail......deal with it. :-P

Hilarious !!!
I'm feeling luved and appreciated - whatever for I don't know.

I missed saying Thanks !!!!!
Gosh, I won't have any excuses left .............
