My rear F@ conversion.....

Finished my rear f2 conversion saturday(except shock change). Need to thank Toe Cutter, Supertex, and Jamie Daughtery.
Purchased the spacers from Jamie. Used the F2 Wheel, caliper, rotor and caliper bracket. Mocked it up first to find out where I needed to modify the caliper bracket. Shaved off the part that fit in a f2 swing arm to get it out of the way. Marked where I needed to drill and tap a hole for the torque arm. Had to mount the arm to the outside up at the front of the swing arm.(Thanks Tex).
Forgot to ask Jamie for a spacer for the arm so had a friend locally make me one, turned out pretty great.

Jamies spacers were perfect. Supertex advice to use the f2 brkt really made it an easier. Didn't have to cut and weld the VFR brkt and no need to trim the torque arm. I've been pm Toe Cutter and he has been a great help, thanks T.C.
Now all my friends think I'm some master bike mechanic, all thanks to this forum. Sorry not a lot more pics of work in progress but when I get rolling its hard to stop and take pics. Needless to say even with out my new shock on it feels way different and looks 10yrs younger.


Still need to make a new rear brake line, using the F2 line for now but its a little to long.

 

Wow....that looks great!

 

The front fender looks a little off but other than that, nicely done Sir. Color match the paint to the rest of the bike & it will look pretty damn good.

KC-10 FE out...
lane: :usa2:

 

Looks great!

 

It is the stock fender . Looks great, have you got to ride it yet?

 

okay got a few questions, i am still in the process of doing rear swap(got sidetracked remodeling house). i have everything you have, except that i do have shock from jamie d(i love it). Modified F3 shock.

now the questions
With the stock(non adjustable) shock, isnt the rear ride height negatively effected?

it looks like you have a Yoshi pipe on it. when i tried to install my yoshi pipe with the new shock there was a clearance issue...can anyone suggest a way to get the yoshi pipe to fit. for some reason its doesnt clear the dog gone area. Should i go with a custom exhaust or is there a simpler way to get the yoshi to fit?

can vfr spacer be used for arm?

Sorry for thread jacking but i am on this part of f2 mod and any help would be GREAT!!!
Congrats on a successful f2 conversion...

 

man that bike looks GOOD with the matching F2 wheels front and back....as much as i know the woman wants me to stop droppin money on bikes and toys and the like, seeing it all set up makes it insanely tempting to start saving up for it.... and fatso, how much was that shock and how well does it ride?

 

The bike willl want to swing wide in turns and is difficult to steer at high speeds unless corrected.

The rake and trail numbers should be crunched on this conversion. You will most likely need additional rear ride height and the correct aspect ratio on the tires, to dial back in the bike's geometry.

 

Really?

You saying all those mods are going to negatively effect the bikes handing?

 

Got shock from Jaime D. @ under 400, havent had a chance to ride it yet. Still been trying to get her up and running got side tracked. hope to get her up and running spring/summer for sure. will definitely keep everyone posted.

 

More that there is a caveat to changing a bike's geometry - as Tony Foale says, "The only thing you can't change is one thing." Meaning, with frame and chassis design everything is interrelated.

 

I understand that, but you think on an older bike with better wheels which can accommodate better tires plus a better shock it wouldn't effect the bike negatively.

 

Only in town, no twisty rides yet. I'm still working on leanghting my fox shock. Then have too see if my shock linkage clears the 4-1 exhaust. But for now she rides pretty decent, feels like she responds quicker.

 

And why would you think that?

The tires are only a small part of the suspension and handling. By just changing tire/wheel sizes you can affect ride hieght,rake, track, rotational mass,weight distribution, braking etc etc. The list could go on and on. There is no free lunch in anything you do. You have to give a little something in order to get a little something.

Like you said it's an older bike. Put better wheels/tires and shocks on, now front end shows weakness, frame flexes now cause of added traction, swing arm flexes etc. See no free lunch.

General rule in the outside world is bigger tires better handling. In most part yes to a certain point. Now you can go faster in the corners than before. But instead of the tires predictable slide point. Now they may just let go and as Emerial says "BAM" your down with no free lunch.

Nicely written, thanks for the post.

 

The loss of ride height is aboot 35mm-40mm. More than enough to mess with the steering. Once dialed in it is the best thing that could ever be done to these bikes.

 

I was under the impression a new shock was going to be used to increase the ride height again.

 

Looking good!!!

 

From my understanding the f2 rear wheel is smaller and using the stock shock will effect rear ride height negatively because it is putting more stress on the frame and swingarm. but with a jaime d shock or adjustable shock, you can raise it back to the "correct" ride height.
