Hello to you all, i am totally new to this forum (or any forum for that matter - First reply post!!!!)
i believe a hot final drive is a good thing, (except for the toasty caramel chocolate love sauce of the BMW's) temperature is the result of pressure and friction,
that S10 motor may not have the ponies of the ktm's but it sure is torqey'
and besides. you have the big long swing arm on the s10 to absorb any possible temperature spikes, i recently did 1200klm in one day and i put my hand over the final drive to see how it was, the entire swingarm had a warm touch, totally normal,
carry on till' you get carried out, K
