Re: reliability and spark plug advice
the gap is .036" (0.9mm) they are pre gapped so you shouldnt hafta do a thing unless you pull the cardboard tube off n drop it or something. if you do go poking a gap feeler in there use a round one because the iridium chips very easy and the flat feelers with their sharp edges are an easy way to do just that.
oem honda air filters will make more power with or without any mods including slip-ons, full systems, pc with tune, velocity stacks. in every dyno run between oem, bmc, and k&n filters the oem out performs. just a heads up. sounds like your trying to squeeze some extra ponies out of it so thought you might like the info. i had the dyno charts showing the data but im not sure exactly what the eff i did with them. ill see if i can find them.
i dont really like to speculate on a bikes tendency to grenade as a whole because my personal experience wouldnt suggest that but my experience is pretty limited when pertaining to that particular bike. it sounds like your mechanic had "a" buddy that had one blow n i mean sure it possible but who knows based on one friend of a friends bad experience. hard saying what happened or how he treated the bike or what the situation was ya know. imo its a honda. nuff said. build quality is one of their strong points really. no bike is perfect n they all have good n bad points but in my experience honda engines are as bullet proof as they come. the 954 is n 929 block is the same the 954 is just bored over n has a different stroke n fi system. the 954 is an improvement over the 929, but still very similar. take care of it n keep up on the scheduled maintenance n itll do you right. if you ride all that hard id obviously keep a good semi synthetic oil changed ever few thousand miles n id bump the valve check up to 10-12 thousand miles instead of 16 just to keep it in spec.
the htev n flapper mod are worth while for a couple reason, one you have a pc n can tune it for wide open htev and just dump the servo. its one of a few small things that are a common fail point on the 929 n 954. another would be the fpr. another would be charging system components like the r/r and might buy a couple extra relays for the fuel pump n headlights. a few have had second gear problems but thats most likely to young newbs jumping on what is essentially a liter bike n learning how to shift gears on a bike for the first time.
treat it right n there is nothing wrong with riding it hard. its ment for that but keep in mind there is a right way to put your bike in kill mode and a wrong way which would be bad for any bike. when your pushing a bike hard there is a lot less room for error and requires much more finesse to keep from tearing it up. miss shifting n bouncing off the rev limiter or downshifting from 4th to second n hitting the rev limiter are bad but not many bikes will take that kinda work for long. im not saying thats you just illustrating the point that yes they are made to be rode hard but the design just doesnt leave a huge gray area for mistakes without damage.
