    Howdo!

    Use my 2013 675 on the track and it recently ate a piston the greedy bugger! So I'm looking at improving the cooling on the bike (water & oil). Just wondering what other people are doing?

    Thanks for any advice or pics.

    Cheers Pablo

    What ratio are you running.
    Less A/F with more water will up to a point work better.
     
  3. Do you actually have an overheating problem to fix though? Other problems like pre-ignition or running lean could've caused the piston to fail...
     
  4. Sounds like other issues but with regards to cooling, u can:

    1) run waterless coolant (won't be allowed for racing)
    2) add Samco hoses to stop expansion under pressure
    3) change the oil cooler/water cooling heat exchanger for separate units or even fit a bespoke oil cooler.

    Has it beer set up specifically to make sure the air/fuel is perfect for the whole rev range? As others say a lean map and some pre-ignition will not only create a ton of heat but wreck an engine

    Bike is used at the track/racing only. Using water only, engine was topend rebuilt and mapped by T3 racing.
    According to them the pistons are prone to failure = heat & high revs.

    Seen a few other racers use separate oil cooler and larger rad. As for revs T3 are developing there own Ecu, so revs and spark can be adjusted accordingly

    Already have the samco hoses.

    I battled with this all year in Elites on my '14, it would do 4 or 5 laps then I'd get the red light flashing.
    I tried air dams (helped a bit), extra volume radiator behind the original but all this did was delay the ovreheat by a few laps.
    In the end I modified a 1098 oil cooler and made a plate to get rid of that heat exchanger.
    The bike now runs 3 bars from max in the warmest of 12 lap races so a massive difference.

    Hopefully picking up a 2nd hand oil cooler to try and combat the heat.

    The only thing I ever used was a addative called Redline Redline Water Wetter Coolant Additive .
    But that was on s road car (Juke 1.6 DigT).
    Which ran hot after the remap and intercooler mod.
