Running an Engine in

[neilr]

Im currently re-assembling my triumph 1500 engine (yes i know most people hate it!) anyway, its been totally overhauled with a rebore, reground crank etc, what i'd like to know is what is the best way of running it in? What i've been told so far is to use a 30 weight oil designed specifically for running in for ~200miles keeping the revs well down, then change it for whatever oil im going to use.


This all sounds resonable, but what to do after ive taken out the 30w oil? surely it wouldn't be too sensible to start reving it within a tappets clearance of its life after 200 miles! Does 6-700 miles gradually building up the max revs as i go sound resonable?

Say limited to 3k then 3.5k and so on? The rev limit of the engine (in the form its been rebuilt) will realistically be 6k.

Thanks.....
