VFRMille

I'm also running the RC51 oil cooler. Changed out the radiator fan to a VTR fan which blows the other way. The engine cools down much faster when you are moving but if you happen to be stuck in traffic on a hot day, the temp goes up & stays there. The stock fan was the opposite--cooled nicely in traffic but not at all on the highway on a very hot day.

Thanks for the replies. Nope, not buying new. I'm an old retired guy, thus the desire to get it all from the same bike, thereby not having to buy complete front end from two different bikes to do the job. However, by the time I did that, it might be less expensive to buy new. All of the small parts will kill your budget. My F4i forks are complete, less triples. I can't remember if they are straight or bent; I bought them a long time ago to modify my XX when I got it but never did. I haven't measured the complete length to compare.

Sorry, my fault.. I thought I was very clear. Must have been the rambling before & after. Quote: Plan is to use XX triples & tubes, F4i lower legs, axle & calipers, 5th gen wheel & rotors. Unquote According to my research F4i fork tubes are 587mm long, 6th gen VFR forks are 627mm, '96-98 XX forks are 630mm, '99-'03 XX forks are 625mm. All of these forks are 43mm diameter. Why would I want to use F4i forks which are 40mm shorter??? Also, one of the threads in here said that the F4i triples change the steering angle, which I was trying to avoid. I don't believe the XX triples do that but cannot confirm, thus the reason for the post. XX triples look to be the same as 6th gen VFR ( I measured mine) , the legs are closer to the VFR length & I can get them for less $$$ I already have a FULL set of F4i calipers & master cyl. as well as a set of 6th gen bars & a set of XX helibars, which are exactly the same as 6th gen VFR bars

Reviving an old thread but closest to the topic. I put F3 insides in my '98 VFR 800 long ago & added a Penske rear shock. The combo has worked well for 100K miles but I am thinking of making a change. I have a set of F4i forks & front brakes but need triples & tubes. F4i & 6th gen VFR have been listed as suitable but F4i changes the rake, leaving 6th gen. The price on those is currently higher than I would like, so looking for options I thought of CBR1100XX. The tubes are within 2-3mm of the VFR length & when I measured my Blackbird forks, the tubes are the same distance apart. These are also more affordable. Any reason why they won't work??? Plan is to use XX triples & tubes, F4i lower legs, axle & calipers, 5th gen wheel & rotors. This would give me a stouter front end & better brakes---assuming it all mates up. I delinked the brakes in my Blackbird, then after thinking about it for a while, re-plumbed it to link back-to-front only. That really worked well. I recently got another SMC bracket & will change the VFR that way while gathering parts for the fork swap. Only requires one new brake line. Already have stainless lines so that one is easy. So. Bottom line. For those that have done the front end/brake swap--any compelling reasons why it shouldn't work???

I bought the RC51 cooler last year after running in consecutive 117 deg days. That coupled with the fan running the wrong way, effectively blocking one radiator made the engine & me very uncomfortable. I changed to the VTR fan immediately but not the cooler. I bought another set of oil lines & will but both on when the temps get really hot on my summer rides. That way I can change from one to the other when I change the oil & not have to worry about the engine running too cool or too hot.
