I would check front wheel balance anyway as you never know and a big single will always vibe like mad went revv'ed standing still. Mine is super smooth but when standing still and slowly going up in rev's at about 3800/4000 the front starts vibing like mad but that doesn't happen on the road. So you could be wrongly diagnosing that one. stick a wheel weight on or pull one off and see if it changes. (worth a shot) May try this as I was going to fit TCK80's at some stage anyway

You mention that it's definitely engine related because it still vibes with the clutch pulled in and just a few revs? is that while you are going along ? because to me that would suggest running gear and not the engine as any engine vibes should disappear when you pull the clutch and go to tickover. My theory was if the vibes were there at speed with clutch in and no revs then it would be drivetrain related, there was nothing, quiet and smooth.

Are the handle bars standard ? Yes with Yam handguards and weights is that where your major complaint on vibes is coming from Its through the bars/tank/footpegs if so try shortening them by half an inch or more if you are comfortable with narrower bars, vibrations through bars is all about frequency and if you change the length of the bars it will help.

have you filled the bars up with sand ? some people do and say good things about that. not heard that one :107:

front tyre pressure and trueness of the tyre, I chased an unbalanced wheel on an audi for weeks and it turned out to be an oval tyre (it was brand new and had a defect) Now if it was speed related I would be looking there but its just over 3k revs the vibes become really bad.

check the timing as you suspect it, it shouldn't be hard to check, not sure on the Ten as I haven't delved into it yet but there's probably and inspection hatch somewhere. on the list

so is this what is happening? you are driving at say 70 and getting vibes and you pull the clutch and are still doing 70 and the vibes haven't changed at all If I pull the clutch and drop the revs to idle then no vibes, if I do the same but maintain 4-5k revs then vibes still there , no change which to me points at engine.

I have ridden my local dealers personal bike which is:

20+ k miles and been used offroad mine 19k
year older
TCK80's well worn Mine has Avon Distanza's which I have no experience of
offroad footpegs ie no rubbers mine has rubbers
Renthal bars , no weights mine is all original spec
Leo Vinci cans which are well loud mine has MTC cans

Now his rode as I remember my new in 09 one, good pull and smooth at higher revs, funny thing is he has not had one before and has spent weeks playing with the fuelling etc to get it to run smoother, after riding mine he is now happy with his :eusa_think:

I have had 2 660R's, a SM and a new Tenere in 09 although the fuelling on the SM was appalling none of them vibed like this one.

Again thanks to all for all and any advice, I was going to take it to a local Yam dealer but I have little faith in the ones in my area :107:

Try undoing the handlebar clamp bolts,remove the bars and re-position slightly and re-fit as per the manual.

Again remove the mirrors and see if there is any change.

I've had a few issues in the past with vibes after changing things in the handlebar and enginebar areas.

well I have tried everything I can think of and its still horrendous to ride so I am weighing it in tomorrow as unlike some I will not pass on a bike I know to have issues to some other poor ****** to sort out.
I have removed as much bling as I can to try and recoup some coin as I am getting rock bottom p/x price for it so I am out of the XT fold again till the next one :toothy9:

Ride safe all

Here's a weird one, took my bar end weights off the other day as I was messing about with the position of everything on the bars and went out the next day without them on.

Made no difference at all, if anything slightly less engine vibe....weird :-~

Well I took the Yam hand guards off , put OEM bar ends on, took MTC cans off and put original on. Thought it might make a difference, did a bit but to be honest the bike was a runt, get one every now and again, had it with cars too. Everything I touched on the bike went tits, oil all over the drive, snapped bolts, skinned knuckles, bolts and nuts fall into the depths and its a full feckin strip to find them etc. Had 5x 660's and apart from the fuelling on the SM all have been fine but not this one, i'll have another but bought a new crf for now so no messing just riding

Good luck with the CRF mate...

I think one of the previous posts might be on the money re fuelling. Imo these things are affected by small changes to intake and exhaust changes. Mine was unhappy when I changed to an oiled foam filter! It's also gone through a bad-vibe period, and I think it was the chain flogging around as it doesn't do it any more since I loosened it off. It vibrated badly through the pegs and tank, mainly. This isn't the first bike I've owned that hated a too-tight chain. Toolish of me to get something so basic wrong, but there you are.

Hope you get it sorted.

I had the same problem with my bike. He has 27K km and I found slightly out engine mounts but the noise and vibrations ware coming from the rear one just bellow the swingarm.
