the first rx-1 we dyno'd made 142hp, since then we have found 137-139hp to be in the normal range. the apex made 148hp, the same day we dyno'd a stock rx-1 at 137hp. jeff

I'm just getting onboard with these 4-Strokers so I'm playing catch-up here... I would imagine you guys have seen pretty much everything there is already on this website... My apologies if this kind of stuff has been posted several times already...

Jeff -- You have any Apex runs that you can post or would Yamaha have a coronary if you posted it (disclosure agreements and such) ???

we will release some info soon. jeff

That's about what we get on our dyno guys. All the 03 and 04 RX-1's (broke in on the trail) made 131-134HP and all the 05's we dynoed made 141-144HP with one making 146HP (these were all broke in on the dyno)
Thanks,
Ray

Alright I know this has been asked on here before. Who has the real answer. Is it better to run regular over premium on a non turbo sled? From the results above it looks like it. Anyone? It would sure be nice to save a few bucks on gas. :?

There is another thread going on your question.

The answer is regular.
