I have 3000 miles on my new 2010 motor in an 08 frame. It has always made a sound other than exhaust sounds more like a rattle rather than a clanking sound. If I pull the clutch in it dosen't go away. Its not a massive sound, and it seems like when I get on the gas it smooths out. I just don't know if this noise is normal and everyones dose it, or if I should be worried. Thanks Russell | ||

these motors are very noisy. wind/road noise and aftermarket exhaust are the only things that quiet them down. | ||

like and angry tractor my son said! and personaly i think it sounds awesome | ||

Not as bad as a Ducati, but not far off, makes a bunch of noises but after 18,000 miles it is just normal. If you think the 1125 makes noise, don't get an XB! lol | ||

Loretta is very noisy now, 28k miles, 2008. Just worked on an 09CR and it was almost quiet by comparison. I'm opening the engine as soon as I get a chance. Zack | ||

I rode with some friends that have harleys and and the asked if I poured rocks into the engine. I guess its normal for our engines to sound like atv engines given that they are engineered by a company that makes mostly atv engines. Anyone know if the can am spyders are as noisy? | ||

I've found different oils make different levels of clatter, too. At least, that's sure what it has seemed the couple of times I've changed brands. Mobile 1 is pretty quiet. | ||
| Russmannnn |
That makes me feel a little bit better then knowing I'm not the only one. On a side note what oil is everyone running I used to have syn3 but think I'm going to swich to Amsoil. | ||
| Mackja |
I run both the Sync 3 and the Amsoil used by EBR, I have noticed the Amsoil seems to be quieter, both are good quality oils. | ||

MY 1125 is noisey at 2000 to 3000 RPM under a light load to me it sounds like the cam chain. | ||

Finger followers make more noise than shim under bucket--more valvetrain flapping up and down in there instead of a direct cam actuation. It's the nature of the Helicon engine, and it's in exchange for NOT needing to remove the camshaft when a shim needs to be replaced every 12k miles. | ||

Yep, my R is one noisy beast too! Also, I use Amsoil. I changed over from HD Syn and I have noticed that the bike does run cooler (by a little) and it feels smoother and seems quieter. Good stuff! | ||
| Russmannnn |
I was hoping that the noise was common sounds like it is. Thanks for all the help. | ||

I can hear the clutch if I do not have it disengaged. | ||

CLACKA-CLACKA-CLACKA-CLACKA-CLACKA... is right until I put in under a good solid load 9k rpm seems to do it. Then the rocker box noise seems to calm down. I use Sync 3. So slapping it seems to work for me. | ||

"I rode with some friends that have harleys and and the asked if I poured rocks into the engine.

Actually Rotax makes a few airplane engines too... If they think the 1125 engine is so bad then you should tell them that real engines don't convert all power into exhaust noise. haha | ||

Mine used to clank like mad, almost sounded like someone was trying to make a symphony out of slapping to metal pipes together when the rpms dropped below 3000. With the EBR ECM, the noise seems to have subsided a bit below 3000 rpm. I just tell everyone it's the sound of character. Sounds better than the sewing machine sounds of the Japanese bikes  | ||

Rotax built Aprilia's V-twins for a while. They also buit the BMW F650 engines. In addition, Dktechguy mentioned they also build airplane engines. Of course they build the Bombardier Spyder engine too. | ||

"Anyone know if the can am spyders are as noisy?".. The one my wife owns is not even close to as noisy. has not that much to do with BRP. Mr. buell did the engine design. BRP just built it | ||
| Rogue_biker |
I think Buell and Rotax worked together to achieve a common goal for the Helicon. Buell set the parameters and of course the application, Rotax designed most of it and of course built it. Like I said earlier, the finger followers cause a lot of the valve clatter, which is what people hear as "noise". You also hear some gear whine in there due to the gear driven intake camshaft (I think its that side). Most engines today use a shim under bucket sitting under the camshaft. I believe that's called a direct valve actuation. But this requires the camshaft to be removed in order to replace any shims. The finger follower that Buell uses on the Helicon does not require camshaft removal but it produces more valve noise. | ||

Finger follower system on an M3 I had made plenty of noise as well. | ||
| Rogue_biker |
The Shim under bucket allows for higher revs and lower friction at high RPM. It's also quieter. Believe me though, if you're a mechanic and need to change out shims, you WILL wish for finger followers! LOL! I believe Buell made these choices to lower maintenance costs (of course they forgot about the engine rotation part). My Firebolt's Thunderstorm also uses finger followers and yes it made more valve clatter. It doesn't really bother me as long as it doesn't sound like a diesel engine I'm good! LOL! | ||

Can't hear it over the Drummer anyway... I use AMSOIL. | ||
| 09cr |
This is my main motivation for making an exhaust for my bike  | ||
| Sir_wadsalot |
Fingers don't float, they retain contact, they are heavier duty and last longer. Very accurate valve actuation. That's why heavy diesels and serious race engines run them. They're actually very trick...and expensive. The HD syn oil is utter shite. Look up the AMSoil white paper test of syn oils. It's the worst of the group. I switched to Honda HP4 (not tested there but I've run it for years, made from burnt coconut shells) Semi-synthetic and my peak temp dropped 10 degrees and it got quieter. It was so hot the panel behind the pipe on the right side got melty and deformed.... |
