On my SXV 550 [...] all I do is pull in the clutch and blip the throttle a few times

Thank you for playing high level music without asking for a ticket.
When I came home from high school, after I got off the bus, sometimes a guy passed by with an SXV. I paused the CD player, listened to the engine and then, when I couldn't hear it anymore, pressed the play button again.

Sorry for the off topic. Unlike many petroheads, I don't have problems enjoying vehicles with powerplants different from mine.

That little girl does a have an amazing sound. Sorry if her siblings bothered you.

That's a bike that happens when you give passionate mediterranians a blanco cheque and tell them to have a good time.

A bit like the Stark and i love the thing.

Haha I think the results in building a place like Naxos with a blanco cheque work out better though.

When my uncle passed away one of my aunts who was tasked with cleaning up his place complained that there were old metal part strewn all over his backyard including a rusted out old motorcycle wheel. I laughed to myself and thought fucking Bultaco. (I lived with my uncle in the 80s and he loved European dirtbikes he let me use his Pursang for a while -I worked on it more than I rode it).

After reading these posts, I rode my EX and MX side by side with a buddy. while the note is slightly different, volume is not. I have noticed a difference between the gen 1 and gen 2 MX, not sure why.

I was thinking about this post while riding my EX the other day. I definitely notice the gear whine is louder with regen/decel. I also notice the noise changes depending on temperature. For example, on a 80 degree day, cruising at 30 mph, I get an annoying whine. But it is only at that speed when cruising. The noise isn't there when it is 60 degrees. On the freeway, there is pretty much no noise, what little is there is drowned out by wind noise. (I ride with street tires, so no loud knobbies there).
When I'm trail riding, decel is a bit loud.

It is interesting riding it back to back with my Zero. The Zero has no gear reduction, so no gear whine, but has a really loud chain drive. So at lower speeds, the Zero is much quieter than the EX. But on the freeway, it flips. The Zero is way louder than the EX.

I notice slightly more noise on my MX with the new recommendation for chain slack (~2" at the slider).

Also, as a side note, I do a lot of slow gnarl riding with my Varg and the new level of chain slack does slightly impact the throttle response at low speeds.

Mounted a new chain due to sumo conversion.
A chain without X-Rings or O-rings.
Seems to be quieter at onroad use.

Read an diploma theses on chaindrives.
They mention where and when noise is produces between chains and sprokets.

So i'm gonna print a 3d cover for the front sproket and equip it with damping material to kill parts of the noise on the source.
Lets see...
