Me and my friend we disassembled the F4i front end. I got the whole 954 end including both tripples. From what I heard you can use the stock F4i neck bearings. The lower f4i bearing going into the shaft of the 954 lower triple is fine. It is the Upper bearing I am having trouble with. It seems to just fall down the shaft of the lower tripple. It not held in place of anything at all.

Please, anybody that did this conversion b4 please help! lol

I am out of ideas.

Oh BTW you guys rock, ill be posting more often once I get my stunt bike up and running. I need alot of advice lol.

 

bearing should fit in the race of the neck on the frame.

 

I just used 929 bearings and races on my f4i and it went together fine

 

954 has a roller tapper bearing and f4i is ball bearing, so your going to have to swap the races out in the neck

 

NO 954's DO NOT HAVE TAPERED BEARINGS! - Only if you put them in as an aftermarket item....stock they have normal roller bearings (Its the same bearing kit used on CBR900, 929, 954) and by the sounds of it F4i also...

go and buy a new Bearing set to suit your bike (Either Tapered or Roller) but a complete set, your problem should be solved...

 

you should buy new ones anyways.

 

So Do I need a set of F4i bearings and races or 954s?

 

They're the same. Either the F4i or 954 will work as long as you buy a whole set.

HOOK ME UP WITH SOME HOT WOMEN WITH LOW STANDARDS THAT YOU BRANG ON SO MUCH

 

Use the bearings from the 929 954. They will go right into your F4i frame. Or if you have the cash just buy a tapered set.

 

+1 ALL ***** RACING SELLS BEARING KIT FOR LESS THATN 50.00

 

And tapered bearings will take alot more endo abuse.

 

Did this conversion in the spring. Go buy the All Ballz tapered roller bearing kit for the 954($32.00). Kit comes with races and bearing. Take the shop your lower triple tree and have them pull of the old bearing and press on the new one. Tap out the old f4i races (upper and lower). If you look down the neck at the lower, you will see a groove in the frame and a little lip where you can put a socket extension or screw driver and tap it out. Same goes for the top (just look up from the bottom of the neck). When tapping in the new races, use a big socket so they will go in straight and flush. Slide the lower triple up in and place the new top bearing in the top of the frame neck. Bolt it up and roll some 600 foot stoppies.

 

if u were cool, u could roll 600ft on the stock front end.

 

this **** sounds real confusing. i swapped out my f4i front for a 1000rr front and had no issues with the bearings. the bearings from the 1000rr fit in exactly how the f4i came out. it was a quick bolt up and go.

 

It's really not.

 

races = bearing cups
