Stupid question, but will a boxer engine get noisier or quieter as the valves need adjustment? I'm guessing noisier. I was going to adjust/check them before I leave for my Ireland trip but as the bike is just so sweet sounding atm I was going to wait until I come back. I reckon I'll only be a few hundred miles past the 12K service interval after the trip.
 
quieter.

the valves recede into the seats & the stems stretch from the force of the spring so in theory clearances will close up.

:popcorn
 
You'll likely feel more vibration and buzzing through the seat and footpegs too.
 
Cheers Gecko. You couldnt shed any light on rocker end float could you?

I'm going to do the valves this weekend and was wondering if this required my attention while I'm at it.
 
Nothing much too it but don't rush it. 1st time may take you a couple of hours but take your time and get it right. 2nd time it's easier. Take care when refitting the valve cover gasket. Make sure the surfaces are clean and dry and tighten the mounting bolts to the correct torque setting and no more .
There is a little round rubber plu that sits in the sparkplug tunnel. Make sure it is clean and sitting properly otherwise you'll get what I got last week.....a very oily boot and oil all over the f@#king place when you ride it !! :o

Take the round rubber seal out of the head - they have a habit of staying in the head when the rocker cover is removed, if you leave it there and put the rocker cover back, it'll split or not seal :thumb
 
Me remove the seal clean it throughoutly and also the cover and cyl side edges. Then it's a celan put back on.

On tightening you must have a feel for it - those guys having oil pissing out from heads usually badly overtighten the valve cover and squeezing the seal by doing so, so it has no sealing effect any more.

There's very little force acctually needed. When thightening the bolt goes on freely into the cover and at some point the bolt instantly get's harder to tighten, then give it just a verrry bit more that's the very limit for a full stop :D This way you get equal tightening for all four bolts as well.

Hmm, I'd need to get hex heads that fit the torque wrench. I must admit, I'm pretty good at judging torque with my fingers so I think I'll stick to allen keys for now.
 
Your fingers are calibrated to the British Standard for torque wrenches..............I'm impressed.
 
The following site has training videos on basic maintenance procedures such as the re-torquing of the heads, valve clearances, rocker arm play, etc: https://www.bmwmc.net

All went well and the bike is now running much better. Blanaced the throttle bodies, treated her to some 20/50 and new filters (fuel was a pain) and plugs and 180 miles later and were still in one peice :D Oh and I seem to have managed to nip everything up just nice without resorting to torque wrenches or online manuals. Cheers :beerjug:

He's from Scotland. 11 months of the year it's easy - tighten till you can begin to feel your fingers - vola! That's 100nm.
 
Nice one. Got to do mine soon...............actually 3000 miles ago :eek:

I'll get me Tardis, bugger the Tardis, where's Billy Piper :thumb

Or......... I'll get me Tardis, bugger Bil :nono .................... I'll get me coat.
