Building F2 race bike
I'm afraid my setup isnt quite finished (nothing sorted on the brake side)... and i winged it for some of the measurements that werent important. Once it's done i'll post up the results. So the info I have for you is:
The spacer between the swingarm and the sprocket carrier is 2mm thick, this is the important one. The spacer on the brake side (including the brake carrier) need to add up to 28mm (i have some dummy aluminium ones i knocked up while i measured everything). This gives you about the same amount of space/slop when the wheel is in but not tightened up.
The sleeve part which goes into the bearing was about 6.75mm deep (just under half of the depth of the bearing, which is 14mm.) So you need to shorten the spacer that goes in the carrier to about the same amount, so they dont hit in the middle.
I'll try and take some pics at the weekend and put some notes on so it's clearer. Pictures says a 1000 words....

hi, The blogs still up
CBR 600 F2 Thunderbike
I'm actually just about to sell the bike so in the process of tidying things up. I did advertise it then I realised that my photo's showed the wrong wheels and brakes + it needs a new battery so decided I want all that sorted before I put it up for sale.
The spec on the blog is also wrong since I changed the motor, so I want to update that to prevent any confusion.

Just a heads up:
Use an F3 rear wheel,do not go to a 180 rear tire.Reason being,the 180 will make the bike harder to turn and will sometimes push the front wheel.The F3 rear wheel is 1/2" wider than the F2 which helps stabilize the rear while adding a wee bit more grip.Plus,it's a direct fit, no modification necessary.

It's already got the 5.5 fireblade wheels in it. So I run modern supersport tyres with the correct profile.... you dont really want to be running a 180 pinched in on a 5.0 rim when it's designed to be on a 5.5.
So far.... i've discovered that it doesnt make it harder to turn and doesn't cause the front to push. It does make the chain run very close to the tyre even with the front sprocket flipped over.

You mean exactly the way it does on every other modern 600 which are running very similar geometry, or for the guys running at the front of the steelie classes here in the UK running 5.5 rear wheels?
Stop being a troll, it's boring.

Being a troll? Gimme a break.Similar geometry as a modern 600? I'm calling you on that one.But do whatever you like,it's your life.You can lead a horse to water....
