There's always a next but I have completed a few recently. I bought a very low mile radiator since mine was very long in the tooth. The fins on the new one were perfect. I took it to a radiator shop for a flush just to be safe. The guy did a great job and even freshened it up with a misting of black radiator paint...it looked brand new.
In putting together the RC51 front end, the stock rad screen was removed just to get that extra bit of clearance. Now with the custom triples, there's no worries of contact with the fender. As I was looking at the stock screen, it was looking kind of faded with some flaws here and there, so I decided to hunt down some screen material.
While pouring through some options online(none of which I liked), I noticed a filing tray on my desk. It had black screen material and looked like it wouldn't block much air. So...out came the snips.
The cool part is, it has rows of rounded ridges across the face for strength which gives it a nice detail rather than just a piece of flat mesh. I gently slid in a wide putty knife along the edges to make room for the mesh then gently squeezed the edges back down to hold it. It's rock solid and has no flex at all. We'll see how long it lasts outdoors but in the meantime, I think it looks pretty good
I had a custom set of triples made. They have a 45mm offset and the upper openings are 54mm to take my custom riser inserts. The R's offset is 50 and the CBR's that I was running is 30. The 30 is just too small for the early VF. Steering radius was horrible. This should bring things back closer to acceptable. I still need to work out the steering stop situation. The previous stop was the frame!
Here's a pic of the triples installed. I hit them with some ScotchBrite to give them a more brushed look. Still have to button things down but you get the idea. Added a metal Honda logo for kicks.
Also reworked my VF/CBR tank vent. The old one was venting under the fill and I didn't like it, it weeped some fuel on to the neck which sat there and ate the paint. This one should be good to go.
Lastly...Without exception, the original fans are the most antiquated part of my bike now. They look old and have cycled on and off for 100k+ miles over 28 years. They MUST be dog tired. I've seen some guys replacing their stock fans or complimenting the stock fan with a Spal made slim fan. I decided to try a pair to see if I notice any difference in cooling.
The plug is even the same for a 28 year old bike...who would have guessed?
They are the 5.2" and measure out at 5.5" with the housing. They definitely pull a lot more air than the stockers so I thought that 2 were over kill. The stockers are housed in a metal shroud that is full of gaps and holes and it doesn't seat tight against the fins while the Spal's sit down tight with all available suction going to pulling air through the radiator. The difference is night and day in pulling power so my thought is...one will be enough?
If you look at a modern CBR radiator, the fan is tiny compared to the surface area of the radiator...like 1/5th to 1/6th of the surface?
Seems like a really strong fan covering 1/3rd to 1/4(counting the upper rad as well) would be fine.
Mock up on spare radiator.
I have 2 and can certainly mount both I'm just thinking why rob extra juice while in slow traffic when 1 will suffice. I've got a few hundred miles on the one fan and it seems to work just fine and it's been quite hot this summer.
