    Even though I don't have an V4, I think that this is one of the most interesting and educational threads here on the forum. I love reading about the little 'tricks' that end up making a seemingly uber-difficult job a little bit easier.

    If I ever pick up a Tuono V4, it truly seems like it would be more than worth it to truck it down to Amauri to work on....and I'm up in NorCal!

    We are very lucky to have Amauri, who just recently performed the valve adjustment (and the complete maintenance work, including the Ohlins fork oil/oil-seal change) on my Factory...I'm not sure how he does his magic, but the bike now seems so much smoother in power delivery with less vibration.

    Thanks again Amauri!

    Hey Amauri.

    Very very helpful thread. This was going to be a job for next month so Im gald I didnt tackle it without the Aprilia tools... and your advice

    How have you found the timing to be on the v4?

    Any suggestions on timing to get the best from the motor?

    Question rsv4 valve clearances

    -2010 Factory with 11k miles all but two EX valves were right on spec.


    Important:
    Bellow is a photo of the o-ring on the cam bearing towers that must be replaced to prevent an oil leak thru the spark plug holes (the parts book calls it a dust seal BTW).
    The list of gaskets needed for a proper valve adj:

    2-) 897442 v/c gasket
    6-) 898410 bolt gasket
    4-) 857074 plug hole to cover gasket
    4-) 857043 cam tower o-ring

    Hi Amauri
    got my covers off at the moment and have got 4 clearances that need adjustment (all tight)
    My question is having read the manual is it absolutely necessary to use the sprocket carrier tool? Havent got access to them and cant borrow any, so can i suspend the chain and sprocket to keep it tight on the drive sprocket below while i remove the cams. Once clearances are done id obviously use the timing pins to set all in the correct position

    many thanks in advance

    Best wishes

    Phil,

    Not trying to be arrogant but if you have enough experience with the insides of m/c engines, you should be able to answer that yourself.

    The first thing that you will have difficulty with is the hydraulic timing chain tensioner on each bank of cylinders.
    The Aprilia sprocket carrier tool holds the tension on the chain so you don't have to deal with re-tensioning.

    If you don't use that carrier tool, the tensioner will pop out to maximum extension as soon as the chain is loosened.
    I've not tried it this way, but it is possible to use a steel rod and pry/compress the tensioner while you place the chain wheels in position.

    Another option is to remove the tensioner and lock it in the fully compressed position, that should make re-assembly easier. Aprilia makes another special tool for installing the locked tensioner back in place way down inside the chain well, see photo.

    Hi Amauri

    thanks for your comments - I suppose if the tensioner pops out then its a head off job - Ill make a gear carrying tool this weekend and be safe

    regards

    Amauri, great tip!
    I've at the moment a RSV4 Factory 2009 at my shop, it's been running 1450km (as new)
    But I've decided that's a good idea to check valve clearance.
    1 in valve was at 0 space! totally 4 was out of specs, to the minus side.
    Thinking of setting the gap to the max specs...
    Is it usuall that the gap goes bigger or getting tighter as it runs? Whats your opinion on this?
    Thanks for doing a great job.

    Note - Kokusan

    Just a note:
    If you have Kokusan flywheel, there is no way to insert crankshaft pin (even modified) without removing the flywheel first.




    You'll need Flywheel extractor 020913Y to adjust front valves on these engines

    I am attempting to fab a cam gear holder tool. Anyone care to take some measurements of theirs?

    Also, does the wire harness running between the rear head and frame need to come out in your experience?

    Thanks in advance.

    Finished making a cam gear holding tool! Should work on my 13 ABS. Have yet to use it tho due to this issue:


    On the flywheel side, the threads on the block look messed up. The aprilia supplied crank timing pin only goes so far, not far enough to lock crank. Has anyone experienced this? Should i turn some threads off my crank timing pin to make the "pin portion" longer? The clutch side goes in just fine. I know i am in the right spot due to my angle and that i can see the crank timing pin receiver coming into view:

    Update on the tools and also a new idea. My cam gear holder is complete, see picture below of it broken down. I can make more of these, not sure on price but PM me if ur interested. I plan on using a clamp or zip tie to hold the gear once i slide it over. It looks like it should work on my 13 ABS in frame.



    Also below... i have terrible luck with clutches. (Ripped up engine and transmission type of bad luck). Here is a tool i made to lock the primary without removing the clutch! I dont get why it doesnt go here in the first place. on the left is the aprilia tool intended location. I just used the little gear section of that locking tool.


    Now, after cleaning threads on block, and making tools, i can finally begin the actual job! Feedback is appreciated, im pretty much making this up as i go.
