    More interesting information.

    Trainedchimp,

    Your sprockets are from the originals that I made for pre R1200 engines.

    As a test for the R1200S and R1200GS, I drilled the one hole per set so that we could see what difference they made.

    A couple of Pelican members volunteered and the feedback was good on the results but the hole was only needed for the knock sensor. Seems BMW have changed the paddle wheel.

    Adventurrer,

    Yes the drilling of the locating pin hole to 3 mm with a carbide bit will make the hole the correct size for a better fit taking all pressure off the spocket.

    All sprockets are now drilled for the current batches I have so no further issue.

    Mag00,

    No worries.

    Kilo,

    I will get back to you.

    I use a new email address but am loathe to publish as I am wary of spam email as I get hundreds per day at the Boxer Performance one.

    To contact me direct use lenmor@activ.com.au and use cam sprockets in the subject, or even just BMW.

    Regards,

    Lennie

    The set I got for my 09 r1200gsa only has 1 sprocket with 5 holes the other has 4 will these work or did I get duped by RFK?

    Look at your stock left side sprocket. If it only has 4 evenly spaced holes you only need a 4 holer. My 2007 left side sprocket only has the 4 holes.

    Can anyone tell me what I should torque the cam sprocket bolts to?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>

    I got the install done tonight, it’s pretty fiddly getting the old sprocket out and the new one in especially without dropping anything into the engine. Everything went pretty well I followed this guide posted by someone earlier. He mentions turning the rear wheels to align the tab on the new cam sprockets I didn’t need to do that, you can rotate the slot on the cam side instead, it moves very easily with a screw driver. Now that I am mostly done everything, thankfully, still lines up; TDC mark, cam arrows out pointing to the same spot on the chain, valves slack at TDC. I did rotate the rear wheel after the cams were on and the only thing concerning it I’m hearing a click from the right hand side when manually rotating the rear wheel, I think I’m hearing the valves on that side – don’t remember if it was doing that before or not. All I need to do now is to final torque the cam sprockets and put the crash bars and tank back on. <o:p></o:p>

    I also checked the valves while I was in there and they were still in spec. :D

    No idea about the clicking but one thing for sure, after all is said and done with the chain/sprocket/etc and just before you put the spark plugs back in, turn the engine over by hand and make sure EVERYTHING is as it it should be (rotates correctly, etc). I think one guy on the PP board had an issue where he was perhaps one tooth off and had to start from scratch. The last thing you want to do is err one tooth off then fire the engine up and have it grenade a split second later!

    Yep, everything rotates fine, turned the rear wheel quite a few times and everything still lines up; TDC mark, cam arrows out and pointing to the same spot on the chain, valves closed at TDC - checked both sides. I think it's all good.

    Factory spec for the Camshaft Sprocket Bolt is 65nm... I usually clean the bolt and the thread with carb cleaner and then use a dab of loctite.

    As for the clicking, you are likely hearing the valve train... if everything rotates freely and you don't feel anything hitting (i.e, Valve/Pistons), all should be well.

    Now tighten those bolts and have fun!

    Mag00,

    No you were not duped. I would never infer that.

    From the photos I would say you just got an early set is all.

    No not you Lennie, I thought maybe RFK just sent what was on their shelf. Old batch or not if I only need 1 with 5 holes then these will work.

    Signit98, thanks. Didn't use loctite becaue I already had most everything back together and didn't want to pull the bolts out again.

    Bike is purring like a kitten. :1drink

    I only got to ride for about 30 minutes today. Bike sure seems smooth, I don't feel like I'm lugging the engine giving it gas in the low 3k rpm range anymore and the mid 4ks seem less vibey than I remember. That was definitely a short test though. So far so good. I don't have any regrets about buying them.

    Do you have an aftermarket can? A Dobeck/Wunderlich or other type of controller on the bike?
