Unhappy 05 - No power after 12k RPM + blue smoke

Hey peps.

I bought it in april and it was like that i just did not notice it cause i didnt rev that high. I did all normal stuff like breaks, fluids, plugs , valve clearences , air filter cleanup (k&n) and oil (motul 7100)

Here are symptomps:
- When i rev it in neutral it will hit red line for like few cycles then drops down about 1k unde redline and acts like thats it.
- When im riding it in all gears i cannot pass 12k - there is that effect of reducing throttle alittle then it get alive for a sec (like Pump)(pump holds pressure at 44PSI when testing in garage) also the amount of fuel is way over what manual says as miniamal - i even changed it to see if there is a diffirence - NOPE) Filter is clean (the 1 in sump)
- Had problem with rectifier - replaced. Now i notice that when bike is hot it will sometimes not charge untill you rev it few times
- tail pipe is black.
- Lately i noticed blue smoke when reving and immidietly checked oil lvl (its low )

What i did :
Tried diffirent pump just to check
Replaced whole Throttle body assy with all sensors still attached to eliminate TPS and injectors (NO DIFFIRENCE)
Replaced camshaft sensor.
Last test was stickcoils and compression (all cylinders around 177 PSI) (all coils in spec but 1 had rusty cap- replaced and when i put it back toogather it was BETTER! for 1 ride (it had power to 13.5k)

Should i toss that bike into the garbage?

Im so tired of it

I sold IT!!!

Sounds electrical to me. I had something similar on my KX500 and it was the magneto/stator. Was in spec when i first tested it. 6month later after testing/replacing other things including the carbs i went back to the stator - it was now out of spec. Replaced that and all was well.


Blue smoke is oil. On power it is rings. On overrun its valve guides. TYPICALLY.
It may be that the oil rigs are goosed but the compression rings are fine. What is the manual figures for compression? I would have thought over 200 for a good engine?

If you are ready to toss it in the garbage.......... I will give you $10 for it ....... lol



Since they all test good and when you replaced the one and it was better temporarily.............Take all 4 stoick coils off, remove the rubber boots (where they slide over the plugs) clean the contacts and make sure the spring clip actually clips the plug (test this by actually installing a plug and make sure it grips it tightly and doesn't simply slide on/off) then put some dielectric up in there, fill those cavities full!!!
put the rubber boots back on and re-install and retest test ride and see

and for god sake.......quit revving it to redline in nuetral WTF........... That is idiotic!

FYI the video os of worthless information really.......... How about what happens when you take off in 1st, 2nd, 3rd gears to WOT and hit the limiter.............. instead of trying to do it on a weak engine that is drinking oil in top gear or top two gears.....

As far as oil consumption, ring replacement and new guide seals would be the two most prone and likely areas to start with
neither are quick and easy............. But I certainly wouldn't go in and only do one- I would do both, and actually I would do a compete refresh of all consumbales......... clearly it hasn't had an easy life and you are adding to its misery

My price just went to $5 now that I thought it about longer...............


woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Thats just to illustrate. I do not do it normally - its not healthy.
I was recording and checking at the same time.

As for the rest - yeah im gonna go back to the plugs and do that (and replace them to regular ones instead iridiums (should have not listen to mechanic ... ;p

Cylinder Compression
Usable Range: 1 085 ∼ ∼ 1 550 kPa (11.0 ∼ ∼ 15.8 kgf/cm 2 ,
156 ∼ ∼ 225 psi) at 350 r/min (rpm)

i had all plugs out and WOT when testing. Assume thats correct.

As for rings replacement - does it involve engine drop? (valve seals can be done w/o i think)(im sorry im just self taught and only at Top engine parts - and i just know what i know from reading and working on this "gem")

ALSO i welcome all criticism and help. Im not an expert on any of this.

i would say your compression is not the issue then

plugs may be

rings do indeed need the engine dropped - cheaper to buy a good new engine? Thats what i would be thinking.

Well if thats the case i think ill bite the loss and sell it as it is at lower price. Cause im broke already

Will see after i change oil if its maybe thined by gasoline or something. Cause i dont remeber it smoking :/

Damn

If you can find/trust a good used engine out there...

Iridiums vs standard is not the problem and if the OP installed new Iridiums- it shouldn't be an issue unless one was bad or something

Exactly, zero guarantee or assurance spending well over $1000 on another used engine will solve the problem or be money well spent- one can buy new rings and guide seals for about $200 and while yes there are other costs associated with this service and pulling the engine and doing the work is time consuming and tedious, generally it may be about $1000 for that work so you would be money ahead refreshing the top end even if $1500 as opposed to buying some other used shitbox for about the same money......

If u have a power commander, remove that first.

Sounds like u have a fuel problem. Most likely a bad injector.


If injectors test fine, it might be your ECU going bad as the 05 models were known for having the ECU act up and fail from overheating.
