Exit baffles (db killers) are usually more effective at cutting noise from what I have found. They do a good job of reflecting the pulse waves back on themselves and cutting down on the noise. No matter what you do, that single cylinder thump is hard to tame since low frequency noise travels through things more than higher frequencies. My VFR is far louder than my Hawk, but I can hear my Hawk at idle in my house much more clearly.
It did get rid of that weird wine sound , so I may end by putting the exit one back on. Even my own family complains when I ride that bike in the AM hours
I liked both, didn't like the squuek in the first but I like the sound a bit better despite that. As for neighbors...they've all figured out when I can't hear my tv because of their (insanely) loud music for more than a minute here or a minute there (eg, it doesn't bother me when they're rolling in or out with it loud, just when they've got it so loud that no one on the block can hear anything inside their own homes because of it), that I'll find myself a reason to ride past their house at 4,500RPM or above every hour from midnite to daylight the next day, which has solved that issue all but 1 time 😂
Definitely try another top speed run. Also, have you considered doing a port and polish on the head? Lastly, do you run 91 or 93 octane fuel? The Lifan 200cc engine has high compression so 91 octane will be the minimum required to get full performance. At 17 HP, the Lifan engine is only getting 77% of the HP it should get with proper tuning.
@@SmallEngineVelocity, yes but not a mechanical engineer. My technical training (at least as far as mechanical devices are concerned) is in Aviation. Automotive performance is a hobby and I've studied a lot material relating to engine performance, modification, tuning (both EFI and Carburetor). Motorcycle engines are very similar to automotive engines in many ways so the knowledge transfers pretty well. I would suggest running 91 octane for a week before re-running any performance tests in order to give the ECU a chance to adapt. After that only run 91 or 93 octane if possible. I'd be interested to see if you see higher top speeds and better power underload (like while accelerating hard going up hill).
glsracer it was nice to see someone had the same suspicions I did. Glad you brought it up. Always nice to hear from an engineer that has a clue what they are talking about. (I was a mechanic, by and large we hate you guys.)
I wish those bike do 120 or 130 mph ...80 mph is weak for me which bike is better for me because you know a lot about them bike ..pls tell me which bike that do 120 or 130 mph

I agree with you on this point. I just got a Yoshimura Exhaust for my Ruckus.

nice man I think i will get that exhaust for my kpr. as for you neighbors, they will be alright rev it up!
Right on!
I'm glad I haven't heard anything yet. Leaving for work on the ruckus at 540am may wake up some ppl. My exhaust is a bit loud too lol
Can’t wait to get an exhaust for the ruckus.
@@SmallEngineVelocity that hotlap 666 is gonna be just as loud lol
But not as lawnmower sounding
@@SmallEngineVelocity I think I'll get a new one after I buy a new bike. That way the honeymoon phase doesn't last forever lol
Pop in some earplugs why do the tuners and lift kit truck owners get all the fun?
Great video! What was the 'official' top speed? 82 MPH?
I stopped pushing at 82.4 mph
good sound but why the bike is smoking ????
did you get any performance boost with the KPMoto Club exhaust?
Heck ya I did

87 octane , port and polish would be awesome and wow are you a mechanic or engineer ?

Where did you get the exhaust? I'm not seeing it available anywhere.
Where can I find loud exhaust for kpr 200 lifan
Saw you riding down champions today
Yea! That’s tomorrow’s video ! Pull me over next time and say hello !
Hey man just bought my first kpr 200 what exhaust did you buy
amzn.to/3cOmgZR
@@SmallEngineVelocity nvm 400 bucks for that exhaust rather hollow the cat
@@SmallEngineVelocity are you selling your kpr exhaust by any chance I'll buy it
I wish those bike do 120 or 130 mph ...80 mph is weak for me which bike is better for me because you know a lot about them bike ..pls tell me which bike that do 120 or 130 mph
You'll need a 600 cc bike to get that. 80 mph is really really good for a 200cc motor
What brand and sizing on the exhaust did you use for the kpr 200?
I need this answered as well
Kp moto club
My RTX muffler is loud it those not have dp on it! Caesar my dad taking test drive on it tomorrow!
Old vid but I see that Miata hidden in there lol
First
:)
I dont hear a squeaky sound I heard someone splooping thier pants
Ahh that’s what that sound was !
Oh, i love annoying my hillbilly neighbors
Lol
