2006 Er6n doesnt reach its stock top speed

Hello,

Since a couple weeks, my Er6n can't seem te reach its stock top speed of 200km/hr
It only reaches about 169 to 175 with the throttle completely open.
I had to retension the chain around the period it started, can it be related?
Also I have a F1 notification, wich is could be my injection beiing a little stuffed or dirty from fueling dirty gas ( I had to gas in a station i dont use alot, and since then the light went on) note, that when I completely shut my bike of, and back on, the light is gone, it does seem to be coming back on when im revving high rpm's while driving, not when in neutral gear and revving.
I have a servica manual (570pages thick) where I found the possible issues as I described you them.

Kind of want to be sure since there are some things i dont understand.. yet :)

Hope you guys can help :)
Thx in advance

There are many factors affecting top speed, especially when it comes to naked bikes like wind, road inclination, gas quality, bike condition and rider's stance.

A worn out or defective chain / sprocket set can cost you hp and smooth operation so it is definitely a contributing factor (I changed my chain and sprocket recently and saw great improvement).

Have yours checked by an experience mechanic (especially the front sprocket) and also take care of that FI indication too and you should hit 200km/h easily :)

Hello again,

Thanks for the info, I did a compression test today, showing a 13kgf compression on both cilinders, knowing it has to be between 9.8 (beiing the worn out border) and 15kgf (beiing the top limit i guess) so my bike's engine condition is good for beiing 10yrs old and having a bad maintanance history before i bought it.

I also checked my airbox for false air beiing sucked in, meaning it has a leak behind the filter, I noticed some dirt on the behind the filter chamber of the box, so thats why i checked, nothng unusual there tho it seems...

as for my aerodynamics... yeah, i think i kinda lost alot by replacing the stock headlight and meter with the aftermarket koso and Urban street headlight... altho 30km/h? pretty much :/
I bought some Injection cleaner to see if that fixes my FI indication, since im convinced it's dirty injection is the cauze of that.
This weekend ill be picking up my "Beast" tho... a 1983, 1100 cc yamaha virago I bobbed out last year :p
Ill keep you posted about the kawasaki to tho.

Thanks for reading, please feel free to advise or comment.... and VRooooaaaaM till next time :)

You are welcome my friend and I hope that you will solve the problem soon. Good to know that the engine is in good nick too, which is what matters most.

Concerning the headlight - meter change I must note that the stock combination is unnaturally good when it comes to wind protection, thus making our bike by far the best naked I 've ever ridden in that respect, so maybe the new stance indeed shaves off a couple of km/h.

And don't forget to post some pics of that bobbed out Virago too, it sounds like a very interesting project!

Hey there, me again...

I'm still having the "not reaching the stock top speed" of 200 km/hr
Today i took my rear fenders of and made some blocks so I could raise the back end off the ground, to check the drive (wether or not it turns smoothly, and if not, where does it come from)
While letting the feel spin freely, i noticed a change in my chain running over my sprockets, it always came back on the same spot, making alot f noise when driving... so i took a closer look, like you can see in the picture below...
It seems that some pieces are missing between my chainlinks... is this normal, i suppose not... but what can i do about it?
Do i need a full new chain?
I cleaned up my chain and sprockets with degreeser (and God there was alot f gunk coming off) and regreases them with silicon chain lube... i have to say its alot better, but im still not sure about what to do next... luckely i got my Old times so i can drive to shool (im re-educating myself) because im a little reluctant (scared) driving with this chain...

Any tips? feel free to comment :)

thx in advance

Hi, it is always recommended to change both sprockets along with the chain, I did it recently and saw great improvement despite the fact that the old chain was still in good condition.

This is the chain kit I fitted (DID 520VX2 x-ring), and it is recommended by other users too:

thanks for the link



Hey, thanks for the links, but i'm from europe Belgium, not that i checked their delivery locations, but I thought GR riders link was more... appealing :p

For the video about chain adjustement, I allready bookmarked it before, and yes its very informative, thanks nonetheless :)

hey , to GR rider, and those intrested

I can't reply to your private message yet since i dont have 15 posts yet, im sure ill be there soon tho :)
Again thanks for the link, it will come in very handy, i kinda need new brake disks and pads to you see :p
i have read on this forum that the The Michelin Pilot Road 4 tires are good for rain condition driving, and since i live in oh so "dry" Belgium.... (sarcasm, becauze it rains like 200 days a year here) those will be ordered for the next change up, to be honest, i need some more, im thinking of changing the exhaaust for a more "deep rumbling" sound, I'm looking for a good rim repair shop because i have a dent in my front rim :/
need new levers since the stock ones kinda look outdated with the updated look (see my garage) and so on and so on...
I'm still struggling with, either go cheap and replace soon, or pay big and hopefully last a lifetime, why i say this is bec i bought some mirrors from "Chine" (China), and the screws are rusting allready :/
had the same with some f my Virago aftermarket parts... I should have known... altho, i bought a mirror set here in Belgium, payed alot for them.. and the bolts rust to... so "frustrating"
anyways, I we (me and my bike) have a long way ahead f us, i'm just hoping that by the time I ame finished with her, my engine will be having around 100k km on it :p
Wich makes me wonder about its life expectancy... Well, i can't say I didnt have fun doing it all so far tho :)

I will conclude with, C you around yall and feel free to comment

No problem my friend, I 've installed cheap mirrors and levers from Ebay and I am very satisfied after almost two years, plus I don't have to worry about them being stolen or damaged. I also have experience with two slip-on exhausts and I can send you links for all the above to check them out.


As for tires, I always fit soft sports because of the slippery roads here but obviously you have different priorities so a rain tire sounds like the correct choice :)

My 2002 cruiser with 30 horsepower has the original sprockets and the second O-Ring chain. It seems to have worked normally for the last 7,000 miles or so since I added the new chain, although I have not tested the top speed (not important to me). The old chain was getting uneven for stretch/wear, but it did not seem to change the sprocket teeth for the next chain. I have only adjusted the new chain once so far. It will get new sprockets for the third chain.


My 2008 ZZR600 with 90 horsepower has the original chain and sprockets, and I do plan to change them as a set, especially because I can see that the back sprocket teeth are starting to wear to a narrower point than stock.

Yes, I can understand the logic behind that, it is an unwritten rule that you can skip timely maintenance work and keep some parts for more time when you are not asking too much from a motorcycle.

The difference between an ok working bike and a bike in tip top condition is pretty tangible when you get to experience it though, and it has a lot to do with the little things :)

Well, I hope that you will see improvement in the braking area with the changes in mind.

Our brakes our powerfull enough but lack feel and immediacy which is a shame. I opted for organic pads, similar to the standard ones, because of the slippery roads here and I kind of regret it, so maybe you should go for road oriented sintered/metallic ones? This should be a good topic for discussion with your mechanic, I guess :)

Our bike indeed has a catalyst and maybe the O2 sensor got dirty and it's easy to remove it and check it for dirt.

Take your time with the repairs and be careful with the top speed runs!

hey,

Ill be out for a while, got rammed in the flank by a Mercedes, who also drove over my right wrist and hand... didnt even cared to stop so the police are still finding him, got some of his licence plate details and color to...
anyways, a little in depth about the happenings...
I was riding my bobber, not speeding, just following traffic, on a single lane, 2 directions road, behind this Mercedes A class as i was heading home from a day of school .
i saw a truck parket on the right side of my lane, only a corner of his front was on the lane, so both cars and bikes could pass easely.
But when arriving there, the Mercc in front f my hits the brakes hard on a road with a 70 km/h limit, my bobber having no abs i cant stop that fast and have to go left of the merc to avoid crashing in to his rear...
but when i do that, he pulls his steer, ramming my in the right side's crashbars that hard, my front wheel gets knocked of the rubber.
I fall, he desides to drive over my arm while escaping the scene...
I couldnt pick up my bike, so some passing-by's helped me, the guys working with the truck standing on the roadside wrote down 4 out of 7 digits.
police came, ambulance came, hospital took photos but the swelling is blocking the vieuw to my bones, but most likely, ill have to get a 12 to 16 week hard plaster...
My bobber... to cry for... the right side's indicators broke off, the crash bar completely bent in, tank airbrush sraped off and a dent... footrest bent, steer bent, brake cilinder broke off, morror scraped off, exhaust dented and scraped and not to forget, the hud panels bolts broke prolly off the shock from smashing on the ground...
around 2000 euros costs, just in parts alone...

hey, some good news today

Had to go to the hospital for new photos of my hand and wristbones, and it seems that nothing is broken... just sprained really hard from tensioning the muscles when the car ran over it all...
I wont be driving till at least next monday, but im happy my plaster is of and I dont have to get a new one for 14 weeks...

So, within 14 days, ill be riding again :)
thx for the support :)

Greetings

My wife fell on a sloped parking lot while walking a few days ago and her left hand swelled up a lot- X rays also showed no broken bones.

I think we have the very old instinct to reach for tree branches as we fall.

When I was 5 years old I learned to keep my hands in while falling- no more picking gravel out of my palms (just knees), and no broken wrists, hands, or collarbones for hundreds of dirt bike crashes, and 1 street bike crash in 1984.

I did break a toe in 1971, and I broke 2 lower leg bones in 1975 from two dirt bike crashes- everything sucked about it except the 3 days with morphine shots and doing wheelies in the hospital with a wheelchair.

My arms were pretty strong after walking with crutches close to 4 months, to go with my skeletal right leg with atrophied girly-man muscles. Nowadays I would probably get some metal pins and a walking boot soon afterwards.

I hope your recovery goes well. Get plenty of sleep and eat and drink healthy.

If you can afford it, a physical therapist might help a lot, even some unformal lessons online for exercises and stretching.

That all sounds terrible man :/ and painfull, my hand is better, but not as it should, there is still a bumb on it and it still hurts when i do certain things... hope it heals fast :)
And well, my bobber is pretty much totalled after all, so a new project is born, i was thinking of redoing some of her anyways...
The only problem is... some parts are hard to find, like the exact same crash bars that are completely bent, and the exhaus scraped... and the custom paint on the right side of the tank is damaged... anyways, i came with good news to...
I dont know if I mentioned it earlier, but I have a Youtube channel where I from time to time upload films from my rides around... that is if my crappy camera works, sinse im poor ( I put all whats in my pocket.... in my crotshrocket...) but anyway, thats another subject.. where was I .. Oh yeah, filming my rides, and uploading them to Youtube...
Yeah, i should say, I'm an amateur... and I only ride for like... 2 years now... dont judge my, advise me :) and try to enjoy them at the same time :)

Take care of the injury, get well soon and you will take care of everything in time.

Did they get the Merc driver eventually?

Here's my YouTube channel too, I mainly post my songs but there are some track and street riding videos:

I am sure you will be back in riding action soon!
