Dumb BRP Engineers don't know nuthin'...... :roflblack:

Well they did put the air valve on the left side of the rear tire ....didn't they ????.....Why ?????.....Mike....:yikes:

For those of us with left handed air gauges? :joke:.

How about late 2008 when I start warning everybody about the front sprocket/main shaft issues? And this was about 2 years before installing the Turbo. One can remember bjt and dtlang from Grand Blanc, MI waiting 6 months each for a main shaft replace on their RS's while in warranty.

You obviously don't get that not all vehicles, engines and transmissions are created the same and that 6th gear on one is not the same as 6th gear on another. A HD engine for example is very happy running at 2,000 -3,000 rpms while in 5th and 6th gears. The spyder obviously is NOT... but go ahead... run yours in 5th gear at 2,000 rpms-- just think of all the gas money you'll save..... :roflblack:. All vehicles will lug the engine at different gearing and rpm combinations.

Safety wiring the bolt isn't going to stop spline damage. The bolt doesn't have to come loose in order for damage to occur. No need to wire the bolt if it's properly installed and inspected at regular intervals. I only know of a few people that had the bolt come out. The rest of us with spline damage had it happen with the bolt 100% still locked into place.

And yes-- my damage continued to happen AFTER the new torque spec.... although I rode mine really hard and thus put additional stress on it. Was on my 3rd sprocket when I totaled the Spyder.

I will say that at least the Mel's ones were cheaply made and probably wore out easily before doing much shaft damage. If they were made of anything stronger than the shaft material--- the shaft will take the damage.

Regardless... the point is that BRP isn't going to cover spline damage on your main shaft if they know you're running a 3rd party sprocket... just like they won't cover engine damage if you're running a turbo.

Did it ever occur to you that since you were on your 3rd sprocket in 50 000 mi and many people have gone much past that with out ever having to change out theirs that maybe just maybe your advice all over the forum like"bob don't tell me you were in 5th at 55 "or "I don't even think about shifting into 5th until at least 80" might just be wrong ,BRP should have used the tried and true set up motorcycle's have used for 50 years and we would not be talking about this now and no one would have had any spline issues , I predict that when BRP ,Honda , or BMW builds a better Spyder and someone will it will have a shaft and more gearing spread lower and higher

I lost my front sprocket and main shaft ''out'' of warranty, Month and a half in the shop,
And 18 hundred + dollars on my dime.

Nope--- because I'm not wrong about this and we know the various causes for spline wear--- most of which have been addressed by BRP. My initial spline wear was due to the extremely high belt tension. Further wear was due to my hard riding style----- revving to 7,000 rpms and dumping the clutch during performance testing, etc.

As long as the spyder runs this rotax engine, it's always gonna want higher rpms. That is a fact that you just refuse to believe for whatever reason.

Those running in 5th gear at 40mph are indeed lugging the engine and causing undue stress on the engine and drivetrain- its very easy to feel it.

There are still toi many variables for engine wear. My concern for running the Rotax at lower RPM would be that it would cause more engine wear, rather than less. Higher gears are harder to turn snd if an engine is designed for high RPMs and forced to operate outside its zone, it will increase engine wear.

When my RT is at 4500 RPMs its smooth and responsive, but responsiveness drops at 4200 and I have to give it motr throttle to keep it happy. By going to a 30 tooth, I would have to stay in 4th, where I'm currently in 5th.

I like the thought process, but don't see it having the results you hope for. Another example... When my Spyder was running into 6 bars over the weekend, I would go into a lower gear, let the engine rev higher and have more leverage and it the temp guage would drop to 5 bars immediately.

Sounds counter to the argument made, but in reality these engines are happiest at higher revs and struggle at lower revs. At some speeds, it takes more throttle to keep them going, so tou msy see lower mileage than with the stock setup.

I'm curious to see how this turns out over time.

Crazy talk!!! ;-). Lol

Don't you know that every engine only has so many rotations and then they just die? Doesn't matter if they are fast rotations or slow ones--- when it hits the magic number they just seize up and then you take them to live the rest of their lives on grampas farm....lololololololol.

Of course you pick and choose what ever you want to think I have said which I never said you should be in 5th at 40 your statement about how it's easy to feel when the motor is lugging is exactly my point and a few hundred rpm at freeway speeds causes no complaints from the rotax at all thanks for making than point you refuse to believe I guess only those that have felt it understand the benefit

And thank for confirming what I said 4 or 5 times that the spline wear was a belt spec issue not cause by tooth count

I never said or implied spline wear could be caused by the tooth count. What I clearly said is that BRP will most likely NOT cover spline damage to the main shaft when you are using an aftermarket sprocket---- how many teeth it has on it doesn't matter.

When I was referring to running it 5th gear at 40 mph I was directly referring to BOB... as he used to do this... actually 37mph I believe he said... but I rounded up giving him the benefit...


Good luck..... I'd keep a close eye on those splines. Mine surprisingly kept working pretty well as long as I put a new sprocket on...but they were sharpened to a point by the time my 3rd sprocket went on. I had planned on having it torn down and fixed (under warranty) this winter before my accident.

I recommend marking the shaft and sprocket with a sharpie...and the bolt... easy visual inspection will show movement. With mine you could roll the bike forward and back while in gear and see the movement. New sprocket... movement gone.

Some of the earliest reports of spline damage (BJT & Dltang) were given a reason of 'bad metal' during manufacturing. It was after this that BRP lowered the belt tension a few times.. and increased the torque specs on the bolt... but I'm not sure if they ever directly attributed these changes to spline wear.... but we all assumed this would contribute. A more direct problem from the high belt tension was blowing through rear bearings....
