2 issues, wont start hot, and bad motor vibrations above 6K rpm

This is a 2003 600rr with 18K miles. common oil changes etc... all but the major maintenance stuff, like valves and clutch...

So the first issue ive had for awhile, but always worked around... pretty sure i know what it is... but my new issue has given me new concerns.

so first, the bike will start no problem cold (unless its really cold out) ride the bike for awhile. turn it off, hit the switch, it clunks, then pulls the battery low enough to reset the ECU (time and trip) the bike will push start without an issue. if i let the bike cool down for 15-30 mintues, it will again start no problem.

Im pretty sure it has to do with the starter shaft getting tweaked when hot... a a new starter should solve it? (reference the tripage motor build from a while ago, for a double case of this)

The new problem that i have more concerns about. the bike has always been a tad buzzy with clipons and rearsets... but it has recently (~250 miles) gotten much worse above ~6K rpm. enough so that it will make my hands or feet tingle/numb in 20mins or so...

The bike wont do it at speed at idle (70mph, pull in the clutch it goes away) so its not the wheels etc... the bike also sounds odd at idle with the clutch in. more so with the clutch out in neutral. at first i thought this noise was maybe the bike idling rough. but it changes when i pull the clutch in and out...

current plan is to pull clutch cover and inspect.... ive herd that the clutch basket nut can come loose ? of course plate/disc wear...


Any other suggestions? am i pointed in the correct direction? things i should check while im in there? any other tests i should do before digging in to far? Planing on checking plugs, and valves while i'm in there as well.

Thanks all for the sanity check!

-Levi

p.s. i would just tear the bike down %100, but it is currently my commuter... so...

Definite starter for the first one. Buzz above 6 maybe check your CCT but that is more of an engine buzz not something going to the clip-ons. Same oil used when engine overhauled?

Been using chevron 10-40, change it every 2500 miles or so.

i just pulled the clutch, the discs are just about new thickness, the plates look great to.

Two things of concern, the oil pump chain seems lose doesnt hang of gear at all). and the clutch outer basket has some slop in it. But i dont think that should be causing all this vibration....

i pulled one spark plug, it looked new, and was right at .8mm gap... so i didnt pull the others...

air filter was a little dirty but nothing like when i replaced it ~3K miles ago...

Mush thanks for the input! glad to know im not crazy about the starter.

Any thoughts ?

If you still have the cover off take pictures of the chain. Going to go with the clip-ons being that you notice it more in your hands. If you went back to stock you probably wouldn't notice it anymore. T

I put the clip on's and rear sets on about 3K miles ago, and this showed up a few hundred ago... harshness is mostly in the rear sets... (like i said it would make my feet go numb through riding boots)

I did put the cover back on... the chain looked great (as did the gears) but has about 3/8" of play in the middle, seemed like a fair amount to me? (service manual didn't list a service limit on this part?)

also the clutch outer has about 1/4" of float all around, but i guessing that's normal to help reduce abuse from the drive train...?

as per your advice, im looking into the CCT, do you know of anyway to check it without having a spare on hand? (free spring length, a loose part, etc...) Is it possible if its worn out enough ill feel it through a wider rev range? I may just pick one up at this rate... only 18K miles... but 8 years....

Again, Much thanks for all the advice!

the CCT does cause any vibrations to those parts unless its wobbling the bike, hahaha,

Id say if those are aftermarket and you dont have weights in your clip ons it took you that 100 miles to develop the strain on your joints, it takes time to develop sensitivities to it,

do this, wear a double pair of socks and some inner gloves something to cushion you,

grip the tank more with your legs and put easy pressure on your hands,

as for your feet you should be on the balls of your feet almost gripping with your toes, if you are on a long ride, move your foot out every once in a while,

or get heavy weights bar ends put the stocks all back on,

GOOD LUCK!

the CCT would make a metal whirring sound like 2 metal circles spinning within each other, around 4-6K its louder than anything but you wont feel any sort of vibes from it, at least I havent

Stickies down!!!!! GEAR UP!!!!!!!

This is not a normal vibration... ive ridden bike with blow motor's (pistons hitting the top of the head) that ran smoother then this...

If the bike showed any performace issues, id think the motor was eating itself.

An oil change and putting everything back together helped naught. the short ride after i was feeling around the bike, vibration seemed most noticeable around the head tube, and tank area. ill be pulling the airbox to check the valves and also get to the plugs better etc...

Thanks

so getting ot the valves... they seem to be at fault! i figured with everyone getting 30-50K Miles before needing to adjust etc.. i would be fine waiting another 4K (didnt check 16, she ran, sounded, and felt great)

the first set came out at .004" .005" .004" and .006" maybe worse, its late for me, ill double check tomorrow.

From what ive read, when the valves start getting far out, some people notice really bad vibrations? so ill chalk it up to that. and get this sorted...

One last thing, do the valves ever have problems getting loose? judging by how tight everything has gotten, i may shoot for the loose side of the specs...

Thanks

-Levi

p.s. if i can swing the cost, i might as well replace the starter while im in this deep. anything else to think about when this far in?

NEver heard of anyone being that loose with so few miles. Depends how far out they were from the factory. Maybe they were already on the high side when you got the bike. T

yup, could have been way out, was the bike geared? or the speedo switched out? did you get it used? Could be more miles than its saying if the valves were that off,


the starter will be no issue since you are in there, with replacing that you will be flushing the coolant,

shoot do the plugs, since your doing the valves, air filter if you havent, other than that, RIDE!!

You can remove/replace the starter without loosing any fluid.

fluid got replaced a year ago, when i uh, had to replace a rad.... *cough*

i got the bike used as the third owner... so no idea how many miles it really had... however it's either been given a new clutch recently, or doesn't have many miles on it... that or some one "did" the valves before i got it( IE didnt know how to use feeler gauges) but OEM sprokets and chain.... that look like they have the mileage on them...

*shrug* at least i know why it acted that way, and know it shouldn't have caused any major damage.

the air filter got swapped a year ago, but i ran the bike all winter...

Thanks again you guys for all the help!
