We're not talking about the stock 250 exhaust, the 300 exhaust is different.
Heaps of $$ too.
The no-welding-tools, no-welding-skills, bath bar version
Yeah I put one of those on it, because without it, it was waaaay too loud. It's defintely better, and better than the stock potato, but it just sounds lame. I may end up with that FMF Q4 setup at some point. I dunno.
I'm not sure why anyone thinks the Q4 is quiet. My ears are ringing after nearly any highway stint more than 30 miles. I can't imagine what the basic powercore would drone like.
The performance and throttle response is great after the exhaust and a jet kit, and in the woods it isn't bad, but I use the bike as a commuter as well and the higher speeds are brutal for noise. Ill be investing in a box of earplugs soon.
Or going back to the bandit and its ~35mpg for my commuting needs
I don't understand why so many people still don't wear earplugs. My KLX with the 300 exhaust on it is too loud without earplugs, and that's even with the quieter core I put in it. I've been wearing ear plugs since I started riding. The noise is just too distracting without them, and wind noise will destroy your hearing too.
Part of it could be my helmet as well. HJC is fairly loud. Borrowed a scorpion once and it was significantly better (bandit)
I've got a bunch of amazon gift cards that I need to use up - thought about buying an exo500 or maybe a GT-Air but I have no experience with the shoei
I'm certainly not one of them, but many hearing experts say you have as much chance of getting hearing damage from wind noise on a bike without a good windshield system as you do from many exhausts...within reason of course. Your suggestion of ear plugs is actually a good one for anyone riding just about any bike short of a Goldwing-type, fully faired, highway, land yacht.
And don't trying arguing by responding to my post, because I won't be able to hear you.
I wear ear plugs everytime I get on my road bike. But when I take the KLX out for trail riding I prefer not to wear them. I have the Q4 and don't think its unreasonable for sound, but I don't do much blasting down the highway at 60 mph either.
CL-X6 by chance? That's what I'm wearing now, to replace an older Thor-branded HJC. Wind noise in the new CL-X6 is much more than the old helmet. However, I've found that the vast majority of that wind noise comes from the top vent; plugging this vent (with a finger to prove the point, or a piece of tape to actually ride with) makes the helmet much, much quieter.
I'm one of the earplugs every ride gang, more so because of wind noise on the highway, and because of intake/exhaust noise on the trail. I work in industry, so I'm well trained in the chronic effects of noise on hearing. Hearing...you'll never miss it until it's gone. And you'll never get it back once it is.
I know an offroad helmet will be noisy, but I figured my road equipment would be better. CL-16 maybe? Integral sun visor.
Either way I wouldn't expect the KLX to bark so much louder than a 1200 bandit with work done (pipe, jets, timing adv, soon head work )
I think regardless ill be operating with earplugs more often, but it was aggravated by the Q4. If anyone plans on commuting 60+ mph for any distance I would look for other options or get good plugs / a good quiet helmet. Especially of you have geared down - I run factory gearing for commuting duties. 6500rpm ~ 65 mph
everyone who has heard my 250cc klx with the powerbomb header & Q4 has said they think its quiet.
I hate loud exhausts & if this were loud it would be listed for sale.
its def louder than stocker....but quieter than my stock 4 stroke ktms & husqvarna....so the noise is relative.
ANY KLXers ny/nj/pa/ct want to hear it im always looking for an excuse to ride
Anyone? Anyone? Bueller... Bueller...
Well, can't help you there. I don't really care what my bike sounds like; as long as it's relatively quiet and works well, I'm happy. I don't know what the FMF on the KLX sounds like, but I do have them on my KTM, and although they do sound good, quiet they are not.
OK so when & where is the klx250 rally or cross country adventure?
Mine is this weekend. Doing a two-nighter on the mighty KLX250 into the Idaho hinterlands.
At a recent ADV gathering I attended there were a good handful of them, and all green!
I made the marcelino cam mod today for the intake cam only. It clearly changes the engine behavior and intake sound. it pulls better, hard to explain, but it feels more like a dirtbike.
more fun to ride, no doubt.
EDIT: rode some dirt roads... This thing hauls now. it goes very well. I also did some more low speed techical terrain and noticed the engine tendency to stumble has been eliminated. it stays running with less throttle and clutch slipping.
In what ways did it change the intake sound? Any air box mods?
intake mods: KDX snorkel. Nothing else.
Can't really describe how it has changed. it is just little different sounding. Maybe little more dirtbike style sound.
