    Valves require adjustments ?

    Hi Guys

    just wondering if any of you have actually had to adjust clearances ?
    My 2013 Capo12 is due it's annual service in Jan, now done 17k and not had valves
    checked yet.
    Of course I'm debating whether to pay big money to have them checked
    only to find they don't need doing.

    Yes, 2013 bike, two valves adjusted at 12K miles.

    Were the two valves you needed to adjust far out of spec?
    40 odd powered two wheelers over 40 odd years. Currently in the garage are a 2016 Tuono V1100RR and a '79 Honda CB550F

    Yes. A significant amount. I can't remember how much now. Both exhaust valves on the front cylinder. One too loose the other too tight. I suspect they had been like it from new TBH. Believe me, I checked and re-checked to be sure before contemplating adjustment! The inlets on the rear cylinder were border line tight, decided to leave them. Will look again at 24k miles, if I still have the bike by then. If they are the same they will be left alone. I get the impression these engines were not assembled with the same care as the V990 Rotax motors.

    I would say the first 12k mile check from new is essential.

    Checking the clearances is time consuming (you have to remove the rad to get to the front cyl). But remember you need to change the plugs, and the coolant, and the air filter as part of the service (the rad has to come off for the front plugs too). If the valves are in, or very close to spec then you can assemble it all with new plugs, coolant and filter and save your self a bundle. But if valve need adjustment you have to decide if you're up for it, or you have assemble everything, go to the dealer and then pay them to do all the disassembly/assembly again. I went for it and did it at home. You can get Hotcams shims online, they are the same size as some Jap bikes. The aprilia ones are more expensive plus Fowlers didn't have stock of the sizes I needed anyway.

    As for service history at resale, I photographed the engine with the cam out and keep all parts receipts. TBH I'm not bothered really, the residuals are so poor anyway, need to save on service costs to try and preserve what is left of the capitol in the bike!

    If you are in the Midlands and you need to have the work done, give Aprilia Performance a try in Tamworth. They are very good non franchise Aprilia specialists.

    I am up for the big 20k service as well.

    My thought was to strip the bike at home in my garage all the way down to valve covers and load it on a trailer to bring it to the dealer for him to open valve cover and do adjustment if needed. I will do the rest myself (filter, plugs, coolant).

    This way I save a lot on labor cost and leave the stuff I am not comfortable with to the dealer.

    I also have help from the fact that we have 3 feet of snow outside and have the luxury of time to do that during our long winter in Canada.

    I have just sent him an email enquiry of approximate cost and amount of time required for the full 12000 mile service

    Will see what he comes back with and whether it will be worth making the trip in the spring.

    I presume that checking / adjusting valves is the same on the Capo as on the Shiver/DD 750, but our radiator needs to be shifted rather than removed. IMHO ckecking valves is a must and not difficult to do. You can then decide to adjust them, as RSTMan noted. There is a detailed illustrated how-to thread in the Shiver/DD forum. The cams are driven by gears from the cam chain so easier to remove to change shims than many bikes. Key tip is to zip tie in the non-removed cam in the front cylinder so you don't lose cam timing. As with RSTMan, I bought a set of Hotcam shims.

    I phoned Griff on Friday about doing the valve clearance check and adjustment on mine. He said he's never worked on a Capo 1200, so declined working on it. He asked whereabouts I was in the country, I told him North Yorks, so he recommended taking my bike to Teasdales to get it done

    Teasdales always been OK for me, that's where the Caponord I had and coolonthecoast now has came from. Bought the KTM there too, get a loaner and take a ride over to Whitby.

    Teasdales seem to be one of the better dealers for Aprilia service in the UK. Based on past experience no way was my supplying dealer going anywhere near the valves on my bike.

    I know people say stick to an Orange dealer for KTM but we just don't have the option so I stick to the people that treat me right. Teasdales is very much a Family business with Andy running the show with his wife, daughter and son plus others.. Dan his son is in the workshop and always seems approachable and does a good job.

    After some excellent recommendations I've booked in for valve clearance check at The Workshop York

    http://www.theworkshopyork.com/page2.php

    To be honest I've struggled to find an independent who's willing to take the work on.....really surprised Aprilia Performance wouldn't do it

    I phoned Paul today and he wasn't phased by it in the slightest, said he's had two Capos in previously. He recommended changing the plugs and the airfilter at the same time, so obviously knows what he's on about

    My Brother and another Mate take their GSs to him and really rate him
