s4r engine rebuilt need help!!!

[Metzis]

Here is the results for now as it is without a proper map installed on the bike... Tomorrow me and my mechanic we are going to tune it properly on the dyno...
The is a fault to the diagram thought and what you see its around +1000 rpm... Brad do you think i should try to dial the cams a little bit or to live it as it is. I didn't go with the recommended way that it's in the manual. I just align the dots on the pulleys with the gap which is behind the pulley.

[brad black]

if the power is peaking at that close to the limiter i'd say it's not too bad.  what is the timing set to now?

[Metzis]

Now the spec are set as if it wasn't with adjustable pulleys so it should +-2 around factory spec....

[brad black]

if you used the factory tools to set it then ime it will be quite a bit more 2 degrees off.  do it properly.

or not, up to you.

[Metzis]

Because i read the article of yours about S4r and st4s being way of factory settings comparing st4 and other 916 being around factory settings, i took all the pulleys into my hand and align them comparing to a non adjustable pulley from a 916. I can try though to adjust them one more time with the recommended way and give it a try on the dyno. In fact i will. As soon as possible i will come back with the results...

Hey guys unsurprisingly my s4r broke down again.... Probably something with the valves the sound was really horrible when it happened... I am done with ducs really.... You love or hate... I used to really love this bike but now i went on the dark side...If i was wealthy enough i would go outside of the dealership and i would set it on fire, Its maybe my 28th bike since i was 14 including four stroke two stroke 1 cyl two cyl four cyl. This crap happened to me again just with a husqvarna smr once more... I am about to burst in tears really, so so tired with this bike...

Really sorry to hear that.

Hey all my little monster is really unlucky including me.... But in the end i was quite lucky too... the problem caused by cc belt skipped 2 or three teeth on the pulley and the exhaust valves of the horizontal cyl hit the piston.... The outcome less the 3 degrees bended exhaust valves which i fixed in the machinery shop two belts and 2 closer shims.... I say quite lucky because when it happent i thought that the bike will never fire up again... Right now it drives really fine but i have to changes the closer shims because with the force of the hit the clearance of the closing get bigger and the clearance of the opener smaller... I fixed openers by changing shims but i don't now how to measure closer shims. now i run 15 opener and around 25 closer which is quite a lot and after 6 k you can hear that something is wrong over there.... I don't of course rev the engine at the moment but i wan;t to fix that asap... My closer shims say 3.1 on them but because of the force of the impact with the piston now the measure something different than that i think... I have like 20 closer shims right now but i don't know how to take the measurement so i can come up with a 3.1 which i want... The shim i have are form 916s so they don't have anything printed on them... I use a micrometer for the opener shims, how i am supposed to measure the closer shims? They have a hole in the middle also what is the measurement of the original tool 88765.1322 by it's self?

[koko64]

Maybe you can get the closer shim measurement tool from EMS in the USA. Maybe you can make one to fit in the closer shim.

[Metzis]

The problem is that i don't know if the 3.1 measurement printed on the shim is the actual measurement of the shim it's self or combined with the original tool. does any one know?

[ducpainter]

The number on the shim is the shim dimension only.

[Metzis]

Thanks that was really helpful i will try to find something to seat in the shim so i can take a measurement... Thanks again... An other quick question... With 25 clearance to the closer can cause any damage to anything in sort term, like three four days of normal driving?

25 what?

thousandths...mm?

I think 4V bikes use a different spec on closers than the 2V, but Brad would be the one to comment on what it actually should be.

edit...

info from Brad's page... http://bradthebikeboy.blogspot.com/2011/02/ducati-closing-valve-clearances-and.html

[Metzis]

0.25mm or 0.008 inches i think....

[ducpainter]

According to Brad's site that's pretty loose.

Whether or not  it will do any damage in a couple of days I can't say.

I'd warm it up and keep the revs down if it were mine.
