heat, fans and burping
Sorry I observe more than I post, but I have a question among the many who are experiencing some 'heat' this summer. I have noticed a slow increase of heat the last couple months and now it's to the point where I am starting to be concerned. It's nowhere near critical but it's hotter than I know it should be so I thought I would solicit some input.
Last year or so... 177 highway cruising, 190-197 on warm days/traffic
Last month or so... 190-195 highway cruising, 220's in traffic, 235 last week!
It's never gone over 235, even in its current state. I decided to replace the coolant with a 50/50 mix. Filled to specifications. Left the filler cap off to 'burp' the system and around 170's when the thermostat starts to open, i get a steady flow of coolant on the floor instead of seeing it 'flowing' through. Does this mean i might have a clogged up system? The old coolant wasn't chunky but it looked old. Also the bike doesn't seem like it has the power it used to... backfires a little bit on deceleration. I refreshed the PCIII map as a precaution. It won't overheat but like I said, just runs hotter than it has ever run, and I know something is 'off'.
Anything I should try first? I have read about the SPAL fans, engine ice, etc. but I don't want to cover up a problem with beefier fans or fluid because the RC has always run within range before. I'm no track rider, and I only have K&N filters and Yosh slip ons.
