  1. I seem to recall that the temp sender is not just a switch but one that gives varying output as the temp rises - the ecu decides when the fan comes on. I think the Ecu uses the temp info for fuel setting and limo home modes etc could be wrong but sure I read it it somewhere Maybe need to check before just linking out
  2. Is the fan free when the radiator gets warm ? Does the fan sound to be running fast or varying with engine speed
  3. Presume air filter isn’t soak or freshly oiled
  4. I'm sure the hub is narrower as well - had to machine my spare wheel when I changed to the newer model
  5. think it was just the rear caliper that changed - think master cylinders are all the same
  6. The 4rt master cyl maybe the same as 315
  7. Is it just since you changed the pads or before. Is the calliper twisted on the spindle he so the pads are contacting at an angle and jamming the pistons
  8. 2015 part numbers for std rear mudguard -I think 87132-NN4-K10 STICKER “4RT”. 87134-NN4-K10 SEAT STICKER 87136-NN4-K10 CENTRAL STICKER REAR FENDER 87135-NN4-K10 RH STICKER REAR FENDER 87137-NN4-K10 LH STICKER REAR FENDER
  9. Honda dealer - parts numbers are available online if google for 4rt part list
  10. I ran older mudguards on my 2015 And 300 rr especially in the wet for that reason. The new 301 and 2020 shape are better the previous ones but are quiet a bit different
  11. You might be able to make an adapter plate to convert the new tank to the old pump
  12. I can fully understand why riders stop competing at the very top level as at some point cost/ personal commitment outweighs results/ enjoyment. The sad thing I see in recent times is that some walk away from the sport altogether. ( this Is not aimed at the 2 recent retirees but an observation over a the last few years) Not sure if they just get stale., only want to do it if they are winning or never really enjoyed it but found they where good at it and was a good parent //child thing when on the up? Having ridden for 40 plus years I could not imagine not having a bike and competing - I’ve had quiet years but never lost the bug and always has a bike in the garage to ride. I appreciate that if not winning they are not enjoying or fear of not being the best. In a much smaller scale I found it difficult as I got older to start getting beaten by younger riders or newcomers but learnt to accept it as enjoyment of riding was greater than that of being top of the results. My first bike was a TL 125 that was a bit of a shed that I went halves with big bro and paid for with paper-rounds and birthday / Christmas money . We spent time tweaking and getting back to a rideable Mount. just wondering in the modern world that this man(boy) and Machine bond is never made - or maybe I’m a bit sad and need a therapist ??
  13. 301 is best mont to date - i was impressed when changed from 260 to 300rr bur 301 is another 20 or 30 % better again. Just the same but much better - nothing obvious but just smoother and more useable Its hard to describe but when I changed early 2020 and let a few local mont 260 riders have ago they thought i should be banned for cheating ???
  14. As A practice thing try several rocks spaced just under bike length apart and hop onto each one dropping front wheel then going again. should help you feel how you can keep front wheel in the air with small amount of throttle
