While I agree with the comment in principle (which I would restate as the specific heat of ethylene glycol is half that of water, hence it takes less energy to raise a water-glycol mixture by a degree than pure water) there are other beneficial effects from the presence of glycol, namely it reduces the freezing point of the mixture so makes it less likely for the liquid to freeze (and expand and cause mechanical damage) while the bike is parked up, and it increases the boiling point so the cooling system can still operate at higher temperatures without spewing steam and coolant out of the breather. The mixed coolants also provide corrosion resistance. I stick to the recommended 50:50 mixture recommend by Big H. My '99 also runs happily through a New Zealand summer at around 78°C under all throttle conditions as long as there is good radiator airflow. My opinion is that the limitation of the VFR cooling system is more likely to be the rate of heat transfer from the hot surface of the radiator to the air than the rate of heat absorption from the hot engine to the coolant, hence the coolant used won't actually affect the running temperature of the bike. Using pure water will increase the heat-up time from cold, and will slow the rate of rise when the bike is stuck in traffic, but won't actually change the peak temperature that is ultimately reached. YMMV.

Good write up by Mohawk some time back on this subject. Click on the links in the thread for photos. This thread used to be on VFRD, not sure what happened to it - maybe it began on this website. Regardless, it gives direct comparisons between 5 & 6 G coolers as well as RC51. Also shows a Hyabusa cooler. For a G6 nothing will be plug and play, space and mounting options are limited. https://www.twtex.com/forums/threads/honda-vfr-oil-cooler-swap.49827/

I’m a dunlop guy as well. I’ve been riding them for decades. Every time I’ve swapped for something else, because of pricing, i regret it, and end up buying dunlops anyway. Arguments with people about tire sizes usually end the conversation. I ride roadsmarts to ntecs, and just cant find anything that is more intuitive in a tire than the dunlops. (Wish I were sponsored for them 😁) i would also check your wheel bearings, and brakes. Sometimes you can have stiction from pads not releasing from the rotors(need pucks popped and cleaned), and sometimes you could have the wrong spacers on the wheels incorrectly, and/or, your spindle is too tight. Tires aren’t the only variable. When weather permits, dig in and check these things out.. good luck and report back. oh ya… some shops also put tires on backwards… just puttin it out there…

Nice find, thanks for sharing that, now to look for Jama 😉

Not to add to more complexity. did you check the head bearings? Many many moons ago, I had a 250 which Was lazy to turn in. The problem was a too tight head bearing.

I'm not being mean, but some of this may be in your head, trying to match a memory that may not be at all accurate. It happens. Brands vary. Tire models vary. Even sizes in the same model vary. Here's the same Dunlop rear in three sizes. One steers like a truck, one has less grip at lean, one is sublime. All are completely usable and feel "normal." Then there's tire pressure, surface material, temperature, and more. Maybe have someone else ride it and provided feedback, or ride another if the dealer has one? Bike geometry, which is nearly always wrong from the factory. Suspension. What you're feeling through the seat and bars and pegs. How tight you're holding on and even the stiffness in your arms will all have huge effects on how the bike "feels." Is your a$$ on the seat or is some weight on your legs? I think that you're looking for a tire solution for a tire non-problem. $.02 worth...certainly worth less. A few more fun ones: And don't even get me going about brake pads. lol It is oil...all over again.

I run only Dunlops, so I can't help you. I never found any of them heavy to steer. Maybe you need a geometry adjustment? Are they worn in an unusual way? Most are, if they came used.

Just make your own out of the hard pipes. These I made for my 95. Cut off the tubing and fill the fitting with JB Weld or high heat epoxy. I like using old bolts as "plugs" and JB Weld them in place, but it's just for a look.

Them pistons may buff out prettuy well on a polishing wheel Thesedid VF400F The inside was yuck

Well contacted the sell company, a one man company, and he is not willing to whit draw the trade I did as he doesn't have the KLE500 anymore, but offered to pay back the in between money to let me fix it.... Well sure better than non.... But ideal would been to get the KLE trade in value also in cash and let him have the Bandit back..... Oh well....
