Did the modified camchain tensioner mod to my bike this morning. It made such a difference!! No more clatter at tick over. The bike has now got just over 26,500 miles. It started to clatter at about 18k and has got progressively worse. The job was reasonably straight forward and I started buy separating the throttle body on the left side from the air box tube.
On reassembly the 'o' ring to the throttle body at the air box tube end was the only bit that was fiddly as it had expanded. I shrunk it bit by blasting it with a hair dryer. A spare one of these would save you a bit of hassle
I disconnected the wiring to the TPS unit and the injector and removed the injector
Sorry these crap pictures!! The lower TB mounting bolt was easy to get at with a standard Allen key. My bike is fitted with HB engine bars so getting at the upper mounting bolt resulted in a multi coupled contraption........could have just taken the bars off
Once the TB was bungied out of the way the Tensioner itself was easy got at. I used a 17mm ring spanner to undo it.
It just pulled up leaving the spring
The links below describe using bent paperclips and magnets to retrieve the old plunger. I did it by sticking my pinkie (little finger

) in to see what size the plunger was. I stuck an 8mm Allen key down the inside of it and was able to fish it straight out.......Twice once to try it and once for the picture
Comparison of the new and old bits. Disassembled
Assembled.
I dropped the new plunger into the hole and bolted down the new cylinder. The new part needs a 15mm spanner and its supposed to be torqued to 32NM.......but your not getting a socket and torque wrench under the telelever. I don't think it would matter too much as long as you don't overdo it.
Reasembly is a matter of bolting the TB back and reconecting the injector and the cables to the injector and TPS. I did a bit of faffing around with the 'o' ring to the airbox tube but I recon this wouldn't be a problem if a new one was to hand for refitting.
After starting the bike up an initial rattle was replaced by silence. Took the bike out and run it up to temperature and it remained smooth and quiet. I let her cool down and started her again from cold......still no rattle. Result I'd say
