talking to the lad that had it before me he reckons its the cam chain tensioner sticking. I've not been out on the bike since. I'm just going to order a new one I think. 

 

I will do some tests to confirm it first.

Ooh, yours makes a different noise to mine, I'm worried again now. TBH, I dont think that sounds like cam chain, you'd be getting some rattle when you let off the throttle. If the cams are high profile, you prolly might get a bit more noise at low RPM. Mine sounds like a bag of nails in comparison 😯

On the other hand, valve train on every bike I've owned got a bit noisy at higher mileage (Over 60k). Both my VFRs did and they didn't have cam chains 🤔

So I tweaked the cam chain tensioner to ad a fraction more tension onto the chain. Noise gone. 

 

The plan is to keep an eye on it until the winter and replace the lot. 

 

I love a nice quiet engine  :)

How do you do that with a 900 tensioner then? I've backed it off and let it take up slack again by turning the screw. Are there any other tricks? I'm starting to wonder if the guides are worn on mine.

Good one - sounds like the coil spring has weakened over the years

The tensioner I just stripped and lubed seem to have some sticking points in the length of the plunger travel. Not enough to stop it from pushing against  a completely loose chain, but as I held it compressed between thumb and fingers, slowly releasing the plunger, I could feel obvious areas where the pressure from the plunger was much less, until I removed all pressure from it with my thuumb, when it moved out a bit more.

 

A good greasing sorted it. Pretty sure the spring is fine, it was just some stiction between the plunger and the slide

That's exactly what I found with the early, short body type

I double checked this and it's the later type, which has made me make a note to check the one on my own bike when I get around to that

The one and only, Len.  12 or 13 years is a good service life in my book !

 

It's coming together, just waiting for a new front tyre and then it's time to look at an MOT

Ah, you're a patient and dedicated man Chris to sort out all my bodges. I bet it looks great. Can't say I'm missing it much as I'm rarely off the lanes these days and this bike is brilliant on the back roads. Although I'm really hesitant about taking the Himalayan to the continent. It just doesn't have the puff to hold it's own on the motorway, something the TDM was a delight on.

I haven't found any bodges....and now you're just worrying me about that on purpose  !  :)

 

I totally understand the enjoyment on lanes with a lighter bike.  The KTM 620 I bought last year has been all I've ridden in almost a year, I actively seek the smaller lanes, and I like inviting mates along who have heavy sports bikes and then they wonder why they don't manage to keep up with this 23 yr old machine with only 50HP !

 

After putting your old 900 back on the road I'll turn my attention back to my own 900. It has your old plastics on it,. My rear disk is cracked and it all needs a good clean....then I think I can be happy with two good bikes, one for the big distances and one for the hooligan. I can't quite afford a 1290 Superduke yet

current plan is to convert the bike to a mk1 in looks, as I much prefer those, and possible add myself a set of USD forks from an aprilia mille with the brembo brakes and 17" front wheel.  I need to find a cheap mk1 850 to use as a donor bike - any out there? none runner would be fine

 

or. I may just leave the bike as is, and start a new project. I fancy buying a vfr1200, ditching the frame and bodywork and building myself a new bike around a new frame of my own design, with the 1200 v4, shaft drive and single sided swing arm. 

 

If I find one cheap enough i will do that.
