Cooling water, no rotation!?

[Killerwhale]

yes dry for sure. could be i used 800...........but as long as it's not coarse it will be fine i guess.

could it be that your block hasn't been machined flat, if the head seems ok?

the head i had suffered a head gasket failure. bloke i bought it from was adamant about it. put it on the surface plate and there was only one very small area that i could get the feeler gauge under.....it looked fine on the glass. it was only about 1 thou out but that was enough.

After sanding i can see that it has taken out a bit just where the head wept first time around....but those wet papers didn´t last long...

I presume You tightened the head bolts with a torque wrench? But did You re-tighten thme after running the engine? If I re-call correctly, I was too lazy last year, and that might have been the reason I blew the gasket. That was a first-timer for me then, no gasket failures before, but I'll make certain I do the re-tightening before I whip the engine next time. Better safe than sorry... (Note to myself, schedule this before upcoming weekend's 3 days trackevent...)

You won´t belive it....just in from the garage and when tourqing and re-tourque and tripple tourque head was OK on fourth time re-check. It then dawned on me....did NOT do this first time around so i did the rookie mentioned above as well.

Ran it up to 100 degrees just now and will re-check bolts tomorrow again before fork goes on.

Installed the new camchain also...timing correct first time trying and everything spot on! Glad i did it now cause there where no clicks at all left in the tensioner!

Well, it´s only time....

Thanks Hasse....you where spot on all the time!

errrm, re-torqueing, I meant after running the engine warm a couple of times, errm, but ok

Think the copper spray-a-gasket (wich is banned in Sweden due to it´s cancerogenic compounds) settles after a while and then you can tourque it some more...Sölle racing had used that on gasket nr.2....and it held together after i took out the plug thingie....good stuff that is!!

So do you just run it in the garage before stripping again? I have the problem of having not found an insex for my tourque wrench wich goes into the camshafts holes so either it´s "by feel" or strip the camshaft....and i really really really don´t want to do that again!!

I wondered about re-torqueing after running the engine but couldn't see it in the manual.

[HansJ]

Maybe it's just me being anal, but yes, I re-tighten the head after a couple of "heat-cycles"... I have ca 250 kms on the clock since last re-assembly, and will definitely do it before the track weekend. I've found a 1/2 " hex socket that fits (think it was at Mekonomen), without the need to remove the cams (which nowadays would scare the shit out of me ).

The spray on thing sounds weird, never tried it, but hey, I am by far not the knows-it-all guy. Good to hear though that You found the problem.

[youngy]

Well you know, it's probably no bad thing to retorque the nuts, but to be honest I don't think it's neccessary. It's not called for in the manual, and to do it you have to remove the valve cover and coolant pipe - 2 pita that can just lead to more leaks.

I guess if you´ve done it 4 times and the wrench was not at 10Nm only once it would be an idea...
I didn´t do it first time....that´s why i didn´t think of it this time and this mess made the bike stand a week longer!

[youngy]

10 Nm? On the cylinder head nuts? They should be 40Nm.

Only the bolts inside the camchain tunnel are 10Nm

Fooking ´ell, well THIS is what´s happened. And i have both Hayne´s and the service manual in the garage...I´ve probably only looked at the left side of pics....damn damn damn....and lucky i wrote this here otherwise gasket two would have blown!! Off to the job and get the large tourque wrench then....


I´LL JUST SHUT UP NOW THEN!!!!



ps. I´m amazed over the copper "spray-a-gasket" now...it has held out with 10Nm for a year!
(i know i didn´t tourque it 40 as my tengtools only goes to 25....)

[Killerwhale]

....and when checking clearences 4 valves where off....

...I just don´t have it in me ordering shims and fix the 4 valves just to re-shim everything when new head and cams are ready to go on.

Think i´ll ride it as i own it a while....

[HansJ]

now repeat this a 100 times:

RTFM, RTFM, RTFM...



No wonder You blew the gasket! When You say you retighten, I hope you don't just do that, but that You back off 1/4 turn or so...

Did not need to re-tighten when the big tourque wrench was out....clicked at 40 and then it was 40!
Had to use hands on one bolt though....just could not reach it even if i bought JULA´s longest 8 (mekonomen didn´t have any...)

If i have looked in the servicemanual all would have been OK as there are arrows to bolt´s with spec tourque.
....i checked the list in Haynes and was sure the one´s to be tourqued at 40 was the head bolts in the frame.
Guess it´s due to a tad bad english as well....

So...now i only got: 4 valves with close to no clearence...a valvecovergasket wich started to leak due to excessive off/on...a fun bike....wich REALLY needs an oil cooler!!

[Killerwhale]

Well, i can say that for having 4 valves out of spec. it goes like a mofo (in a good way)
Tried a little "motoman" today even if the bike´s been started....pulls like a train right to limiter. Will actually go back to 17/40 now so we get some speed as well

Will try to get a dynorun asap before tornado cams and an insane head...game is on...it´s my bike against a Swedish Highland superretard twin....will be tuff though...
