timmythecop Posted April 9, 2013 Author Share Posted April 9, 2013 not yet. I ran outta time. I was reading in another place where a racer had the same setup and with the triples DOWN 1.5 inches, had 8mm of clearance. I have gone UP almost an inch, so I should be OK. We will know more tomorrow. If it is a go, I'll just swap the F2 wheels on with the speedo drive and be groovy. Only other stumblers are fork-lock, ignition switch and fuse block placement. I think the bars will clear everything ok, but since I am in charge of how much fork lock there will be. I'll just set it 1mm away from contact. here's on with the same front end and after many races, no contact with front head was reported Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted April 9, 2013 Share Posted April 9, 2013 The handlebars only gripping half the fork tube gives me the heebie jeebies. Link to comment Share on other sites More sharing options...
timmythecop Posted April 9, 2013 Author Share Posted April 9, 2013 I couldn't take the suspense, so I went back in there. Took off the caps and collapsed the front end all the way I have over an inch and a half of clearance, clarence! so to make everyone happier, I pulled the forks up a half inch to jibe with the clip ons better and I sill have an inch of safety zone.

Member Contributer InvisibleCities Posted April 9, 2013 Member Contributer Share Posted April 9, 2013 Build is getting interesting - way to stay with it! With this in mind I am curious to see how the geometry will settle in. A few numbers for reference: From memory the CBR600F2/F3 forks are (when measured from top of upper fork tube to center of axle) 780mm. (If you have a chance could you please confirm?) To note, the VF500F forks are 802mm and YZF forks are 805mm. With a 160/60-17 rear tire you have an overall diameter (if I am doing the calcs right) of 622mm. Diameter in inches = rim dia inches + [ (2 x aspect ratio x section width) / 25.4 ] or 17 + [ (2 x .60 x 160) / 25.4 ] = 24.5" (622mm) The stock VF500F overall rear wheel diameter is 654mm. This is a difference of 32mm (1.25") give or take a fraction or two (divide by two for the effect on the overall rear height, or 16mm in this case, per Gaz's note below). With this in mind I think you'll need some additional rear ride height for sure (contingent on the front fork length too) - perhaps an F4i shock conversion for the shop clipboard?

GazVF500 Posted April 9, 2013 Share Posted April 9, 2013 ICs, if I may - the reduction in rear ride height would be half the diameterical difference, so 16mm. I'm not sure what tyre is being used at the front, but I used a 120/60-17 and calculated a 2.7mm increase in front ride height based on Bridgestone's numbers for the BT016s.As Timmy has measured some clearance between front mudguard and radiator, could some of this difference be regained by sliding the forks up through the yokes?

timmythecop Posted April 9, 2013 Author Share Posted April 9, 2013 One of the reasons I did not seem bothered by the loss of ride height, is because my double extra secret probation part is a Fox twin clicker. I should be able to regain all that was lost in the conversion. Watching the mailbox like a hawk, for that box containing the shock. It was supposed to be secret, but I don't want you fellas thinking I was going about this William-nilliam. Link to comment Share on other sites More sharing options...

timmythecop Posted April 9, 2013 Author Share Posted April 9, 2013 Measuring my F2 forks, hangin free with no wheel on them, I got 30 7/8 or 784mm. After messuring an F3 front end side by side, all dimensions are the same, except the F3s are cartridge type and have no provision for a spedo drive. ( or any tab to keep drive from spinning.

Member Contributer InvisibleCities Posted April 9, 2013 Member Contributer Share Posted April 9, 2013 Thank you for checking the length. On a side note, for reference, '94 F2s have cartridge forks, 91-93 F2s do not. Keep up the great work! Link to comment Share on other sites More sharing options...
timmythecop Posted April 9, 2013 Author Share Posted April 9, 2013 stuff is so similar, but all the variations are hurting my head. Next bike IS STOCK, dammit here we have a different front end on there complete with speedo drive (we must be legal, mustn't we) Got the ignition barrel sorted with a minimum of grinding (and after I bought the correct star bit. The triple looks trifling because I pulled off the fake carbon sticker. Link to comment Share on other sites More sharing options...

Member Contributer InvisibleCities Posted April 10, 2013 Member Contributer Share Posted April 10, 2013 As an option, the '93 VFR750 front fender is one of my favorites: Link to comment Share on other sites More sharing options...
timmythecop Posted April 10, 2013 Author Share Posted April 10, 2013 the wheel shown is a 4.5 with a 170 on it. A 170 does fit inside the swing arm, but the limiting factor is the chain. If, for some reason, you HAD to run a 170 or possibly a 180, there is room to shim the front sprocket, but then you run afoul of the frame after a while. I will run a 160/60, going with the lower profile tyre because I can easily adjust ride height. That VFR fender is nice. I may have to look for one. I've got some ideas for the fuse box relocation with the bent going towards waterproofness. Last night I solved the front brake switch and brake fluid bottle snags. now just need to spin this around near sharp cutting instruments. Link to comment Share on other sites More sharing options...
Member Contributer Kel Posted April 10, 2013 Member Contributer Share Posted April 10, 2013 now just need to spin this around near sharp cutting instruments. F2 wheel? Just throw the 500 cush in there and be done with it. I ran one on my portly R with no issues. No machinng needed. Link to comment Share on other sites More sharing options...
timmythecop Posted April 10, 2013 Author Share Posted April 10, 2013 that is a 500 cush. It has to be machined in order to use it with an F2 wheel in the tiny 500 swing arm. I have too press out the studs first, then the lip around the bearing needs to go back 10mm and each sprocket mounting boss needs to go back 10mm. Then I have to source some strong bolts to use that are, you guessed it: 10mm shorter. Link to comment Share on other sites More sharing options...
Member Contributer Kel Posted April 10, 2013 Member Contributer Share Posted April 10, 2013 Gotcha. I thought maybe the smaler 500 cush didn't need machining. The R must be just wide enough at the front sprocket to work with the smaller cush. Continue on. Link to comment Share on other sites More sharing options...
SEBSPEED Posted April 10, 2013 Share Posted April 10, 2013 Maybe you misspoke when you said "press out" the studs. The 500's studs are threaded in, you'll only need a large vice grip to remove them. Been there, done that. Link to comment Share on other sites More sharing options...
timmythecop Posted April 10, 2013 Author Share Posted April 10, 2013 here is a side by side with the Fox nearing maximum height. Should be no problem setting this booger up. and for all you OCD fookers, I'll take care of spring colour later.......... Link to comment Share on other sites More sharing options...
