2016 350rr 158 hr report

Recommended Posts

Well I'm up to 158hrs on my 2016 350. No issues at all with the engine up to this point I've just pulled it down to do a top end rebuild. The rings are still in spec as is the piston could have left it to 200hrs easy. Its a major pain to do the top end you have to pull the engine from the frame and its one of the hardest bike engines I've ever pulled out, you have to hold your tongue just at the right angle and its heavy or I'm old and weak. The valves are still in spec which I'm very happy and relived with. This Beta is Yamaha reliable for a 4st. 

Bit of a disclaimer about me and my riding style! I don't rev it to the limiter very often and I'm sure as hell not one of the guys sitting on the start line smacking off the limiter. I ride the bike in the fat part of its power in the upper midrange I'm sure this is reflected in the engine life. Air filter every ride and I clean the airbox as well, engine oil every second ride and a filter every second oil change. Will post up some pics later for anyone who is interested. One other thing the rings SUCK so much tension and you have to use a ring compressor also the piston clips are made of Hercules's  hair very tough. Forgot also did the cam chain it is also in good nick.

Good report Marty! Sounds like you've taken good care or your ride.

 

What kind of fluids are your running?

I run a Local Aussie oil made by Penrite its called HPR10 I run it in both the engine and trans. In the air filter I run motul and hate  the stuff but it does work well.

New camchain in, the bolt holding the oil jet was not as tight as I would like something I'd check if I had one of these bikes. Heaps of loctite on the guide bolts.

All pretty and new. You MUST use a ring compressor for this the ring tension is crazy. The oil ring is one piece common for Euro bikes so I'm told as is the scraper ring its one piece and cast, very different to Jap stuff.

Was that the piston cleaned up or a new one?

New one not pulling it at those hours and not replacing it. Did piston rings and cam chain.
