Hot running, float height too low?

[Alf]

Today I´ve tested the new relay mod and, like Pat told me, new float bowls fuel level, 23 mm, from the previous 21 that I found them
I´ve chosen the worst possible scenery: hot day temperature, curvy, tight, slow known road that go from level sea altitude to 2.000 m. high in 40 kms where I drive very hard form 2 - 6.000 rpm all the time in 2nd/3rd gear (more is impossible: you go to the ditch... and the ditch is at the bottom of a 500 m cliff. Scary! )

The bike accelerate with fierce power, I´ve near eliminated the backfires... but I´ve got HOT. Even with cold sparks and with big oil cooler, the oil went to 120ºC in 30 kms, when last week, with similar temperature, didn´t pass from 105ºC in the 40 kms

So I think I have to revise the float bowls level one more time, leaving them in 22 mm, but really I don´t know if the temperature increase comes from the lean fuel level setting or from the new power found with the relay... or from both

I will inform. Any suggestion?

Yesterday I rode hard more than 200 km. for curvy and tight roads. The bike only get overheating when going uphill. The rest of the time the temperature is normal... so It must be that the carb cubes get empty of fuel and make the mixture lean when the bike goes uphill, helped with the tail down movement in hard accelerations

So I must change the float bowls heigh and leave it in 22 mm. Its a pity because only in that situations the bike overheats, and the backfires have disappeared (almost)
