IIRC, the F2 wheels are 17x4.5" which should mount a 160 or 170 tire which would give me good turn in being smaller, still offer the grip I'm looking for, offer better braking and update the looks of the bike.

Same size rims i am using, don't forget that the 17's will lower the bike by roughly an inch at rear and nearly 2 inches at the front. I am using GSXR1100K forks and have had them lengthened to get the ride height right, finding slightly longer shocks for the rear is no problem at all.... ;)

Then I guess I'm on the right track again. I read that 14-14.5" shocks were the way to go. Could you get me a measurement of your fork, Mick? I'm curious to see how much shorter mine are, although they're off the sport touring YZF/Thundercat (EU)

I might get some Progressive replacements for the time being until I can get some Works and make sure I'm a dealer as well.

I'll take some pics today of the swingarm and i will measure the freestanding length of my forks. I have progressive springs in my forks, they were used on a TZ750 Yamaha race bike.... I am also using the 3.5 inch front wheel....

I need to get this frame out from the rear of my shed, i took 2 pics, if you need any more let me know...... length of my forks are 1, Fork top to bottom of fork as the bike sits with the engine in is 803mm. I will have to make some room so i can jack the bike up to get a free standing length....The swingarm was shortened from the rear and the monoshock section was removed and re braced

Thank you much Mick! Quite the beefy swinger you got there.  I'd love to see more pics, but I can wait until you're able.  I'll get to measuring, I know I need to get some for another member as well and post up my findings.

Speaking of findings, the more I work around this bike, the more things look different.  The cooling fins on the head have cast marks on them as opposed to the cylinder's cooling fins....

 :o Is this normal?  I don't run into these things all day, every day, but I'm curious now as to what's been done to the motor.

Just measured the forks.  As it sits now I'm at 32.75" or ~832mm, so it should actually sit a little taller in front, which would explain the reverse rake now.  Playing with wiring as I type, always a pain!

DId you ever sell the rims and front end it came with?

After looking at it I think its a Canadian CB1100F wheel set. They were rear disc and would have been a pretty decent swap.

13 in the garage and counting...

Still have the setup.  They're CX wheels, there was a sprocket carrier made up for the rear for it to adapt it to the bike for chain drive, also disc brakes.  If they were from a CB, there more than likely wouldn't have been an adapter made.

So today I popped off the valve cover after getting some wiring sorted out and found the following....

Dual valve springs & Aluminum (?) retainers

Adjustable cam sprocket

and an Andrews Camshaft with EP-13 stamped on it  ;D

The underside of the valve cover is about spotless and gunk free  :o

So after all that and after work, I headed south of me and picked up a CBR600F2 swing arm, rear wheel with rotor, rear brake caliper and stay, and sprocket carrier for about $135  ;D


Don't hate me too much guys  :D

Now with F2 swing arm and rear wheel  ;D



Just measured free standing length, and from axle center to axle center I'm at 5ft and 1.5".  I know it's longer than stock for sure right now.

Did you have to do any modification to the swingarm?  How does it fit in the frame?

The spacers need to be shaved a little, and I mean millimeters, and either I need to get bearings to fit the stock swingarm bolt or enlarge the holes in the frame to fit the F2 swinger bolt... Other than that, there is no other modification needed to make it fit in the frame. I didn't measure the two against each other before mounting, just removed the stocker and test the CBR swinger to the frame, only the spacer in the swingarm was causing clearance issues.  However, unless you run it monoshock, then you'll need appropriate bracing and mounts, if you keep the stock dual shocks, you'll need to weld lower mounts on the swingarm itself.  I'm still in the air and discussing with a few members of my usage of the bike and pros/cons of both setups, I'm leaning more towards Monoshock right now and it's cleanliness and centralized weight.

Very nice.  I'd really like to see a CB750F with monoshock.  You're stoked on that motor, lots of good parts in there, wonder what the pistons look like?

You've done well with that engine Andrew, have a look at the clutch, you may have a Barnett in there as well....
What size is the bore mate.?

Not a clue yet, you guys are tempting me to pull the motor before I'm ready, lol.  I'll let you guys know as soon as I start pulling it apart and make sure to take plenty of pictures of my findings.

Raised the bike a little front and rear to do a test on how a monoshock would look....



The CBRF2/F3 arm is 3.25" longer than the stock F arm, and after talking with Retro, it's about 50mm longer than his setup currently.  I know it looks huge, but there isn't a seat or cowl on it yet either.  Funny little finding also, I was testing things on the bike and my 600RR rear caliper is the same as the F2, other than the color  :o

Thanks, should have my f3 shock here next week for mock up  ;D

Progress has slowed, have to get a few bikes out of the shop before I can dive back into the CB again  :-\

So, I got some time after getting two bikes done today and got to cutting the very rear part of the frame off that was already an abomination from the PO  :-\

I ended up looping it with a piece I bent up previously, cut it, tacked it on, broke it off, ground it a little to angle it a bit higher, then tacked it back on, and then hit the outsides with a body hammer to round it over. So here it sits now.... (I hate when I have tools laying around, but I was too excited after getting this fitted)

What are the plans for the seat? 

I like the Speedster seat cowl shown on ebay, http://tinyurl.com/3u4jyuu , in which is made by a forum member lwitchey on here, but it's made 3 1/2" longer than the furthest point of the loop is.  I know I was putting the cart before the horse on the loop before getting the seat cowl setup, but I needed to do something with the bike and I couldn't stand the cobbled up welds on the rear part of the frame anymore.  I can always bend up another piece and make it fit, or I can make my own seat cowl, I really hate laying fiberglass though.  I do plan on fitting a metal pan and welding it to the frame so I have a splash guard that will also hide away the electronics from view as well as giving me better options on seat mount locations, ie further forward or backward.  I was thinking on playing with some 1/4 turn fasteners, but I don't think I'll be needing to pull the seat off all the time after I get everything sorted out.
