that's a good question...if ya use the 44, ya get the benefit of lower torque/stress on the new parts. if you use the 36, i'd suggest a lot of pedaling to take the initial load off when letting the clutch out, but then you'd have the benefit of a bit more speed while still laying-low during the break-in. engine rpm and stress are the crucial factors. use your discretion when choosing, & base your choice on your riding style and amount of mechanical experience.
my opinion: if you're "just" a beginner, stay with the 44 and only do 20mph tops for the first coupla tanks. if you understand the gist of the above disjointed rambling, then go with the 36, saves a re-install later 8)
