I've been looking at Force 52 engine specs and there is not much in it with regards to power output, however the 46 must rev to 16000 rpm whilst the 52 revs to 12000 rpm.This tells me that the 52 engine should outlast 46.however the 46 can be had for as little as £85 for a complete new engine.Given the cost of the 46 new piston and sleeve at around £60 it hardly worth fixing them with off the shelf spare parts and this is why I purchased two new complete 46 engines to start with.
