Sounds odd to me fella.
I ran kit spur with 24 pinion at the weekend on a speed passion 5.5 with Lrp speedo.
Hot day and fast southport track - it was hotter than normal - but not a problem.
On grass tracks I run a 22 pinion and the motor comes off warm (you can put your hand around motor without getting burnt!)
Is the 410 transmission free / anything binding - maybe a cvd pin catching etc ?
