After doing valve shims put the cams back in and put the cam chain on - both cams slightly off marks due to compresion of valves - what is need ideally is a tool that fits in the two holes in the end of the camshaft - and the fact that ideal line of sight would require removal of front end! 

 

was able to fit chain on exhaust cam by using a lever in the sprocket to line up timing marks on cam and cam holders while holding front of chain under tension  - slipped chain on and then had to worry about inlet cam and sprocket - 1/4" drive extension kept the exhaust cam lined up (with a bungee cord holding it under tension)

 

the inlet cam also required rotation to line up with marks - after a couple of tires it seems i now have the timing set up - next thing pick up gasket for cam chain tensioner - put some tension on chain and rotate engine a couple of time and hope all the marks line up

 

then onto rebuild but double checking fuel level height as i am not sure using floats off the bike has been accurate enough after i replaced emusion tubes and needles

Went to Wemoto and ordered a new LHS front indicator - turns out that my new place's gravel driveway is not equally solid in all places you might want to plant a TDM850's sidestand.

I used plastic strips to keep chain and sprockets together, avoiding the necessary extra hand... You think it would be a good idea in your case as well ? I'm kinda curious if there is something about the method that I've missed....

I had to rotate mine ~10 revs before the beautiful 'tick' indicated tensioner was finally doing the job.

I slowly rotated mine the opposite way for a quarter turn and it tensioned the chain spot on.

 

Using plastic strips is prolly ok if you don't intend removing the camshaft sprockets.  Otherwise, you'll find you need to rotate the cam & sprocks to get access to the sprock bolts and it's not possible if it's all stripped up.  Might also be a pain if you intend removing the camshafts as there's nowhere for them to go.

Ordered the correct battery today. 

[Borderraider]

Nut & bolt tightness check (suprisingly both dome head bolts on front mudguard slack)
Tyre pressure check, all ready to head off to Germany tomorrow.

I was removing the sprockets, the whole point is getting it right back without loosing inlet sprocket position in the process of sprocket/chain reassembly. The important point is when you insert sprocket bolts - then you already have aligned sprocket and chain and don't need an extra hand to handle both chain and both sprockets simultaneously. Just align sprockets with chain when they are loose and strip them to chain, then rotate cam shafts slightly to align sprocket bolt holes.

I can't really se an as simple solution that would remove the need of an extra hand.

 

It might even be an idea to do this before removing sprocket bolts, if so you would need to remove "opposite side" sprocet bolts first. Which, I believe, is not a bad idea anyway.

I agree it is fiddly lining up the chain and camshafts but once you've done it a couple of times it gets easier.

 

Be interesting to know how your method goes so keep us posted.

Now that i just dont believe, once was enough

Well, if youn meant me, I've finished the job. Nother 42,000kms until I do it again (I hope). Or you meant the OP, mh1848 ?

[Studley Ramrod]

Ah right, for some reason, I thought you had yet to do the task. My bad.

[chrisr]

Looked at it longingly as I got in the car, riding tomorrow though!

[danceswithmopeds]

Fitted new tyres awhile ago, was never really happy that chain tension was exactly right. So set it exactly as  I  wanted.

Discovered that there is a huge build up of crap underneath, and centre-stand has gone really rusty. 

Next? find where I left my wire brush collection and spray Hammerite.

Washed it in a diy-carwash-boot, not entirely sure if the bike will benefit from this rather hard wash regime on a regular basis. Just had to remove all stains from weeks of maintenance....going for this year's 3-day trip with friends. I believe my old MkI is better than ever, it feels a bit quicker from low rpms after reshimming valves. Or it was imaginary caused by lubricated throttle cables & 1 month of standstill and forgetting how good this 21 years old babe is.....

 

BTW, gotta tell you - I changed fork "oil" on my girlfriend's '96 CB500 the other day. And I had a slightly bad feeling about not changning oil on my forks since '07 or something.... She  simply had a new bike ! And even if I have experienced the effect of renewing old (now, last time - 7 years old but still looking like oil), this was amazing ! On test ride, my first thought was: "What is it with them rear shocks ?", and the answer was obvious: Before you wouldn't notice because of the shock waves emerging from the front, now you start doubting the condition of the rear ones...as I did with my MkI after fitting racetech valves ;-)

I believe the old CB hadn't had new oil ever. The carbon/water-like substance didn't at all look like, and certainly didn't work like, oil....

[Yami]

Mine is looking like this at the moment.

 

[Doggy]

Actually ridden it!

 

I suffered a minor stroke at the end of July and having done my 28 days with no driving or riding (and done a fair bit of rehab) I actually rode the old girl for about 100 miles before my left arm (this and my hearing being a little challenging at the moment) gave out on me.

 

She's very quiet and smooth when you cannot hear very well - so there's a bonus!!!

 

I am looking forward to squeezing some more runs before the weather turns nasty again.

[dablik]

Good for you Doggy, glad to hear your recovering, small miles after a stroke fella, soon be back up to par.

 

Got mine out today and did another 200 miler around N Wales

I felt the handling was going off a bit after a long fully laden ride on some poor roads so I tweaked the suspension preload and damping a little harder at both ends (totally unscientifically) and added a couple of psi to the rear tyre.  Feels better now, steering feels a bit more accurate.

[Deauman]

Had an urge for a bit of stilton for lunch.  I have an Asda less than a mile away, a couple of nice delis within a mile, Morrisons two miles or the Dairy where they make the stuff about 15 interesting miles away.  Guess which one I chose.

Actually it was such a nice morning that it turned into a 40 mile trip which is quite a lot for a bit of cheese but it worked up the appetite a treat.

[chrisr]

Rode mine up to London and back, one ( or both) of us was having
an off day, very snatchy all trip, but it can be like that sometimes,
Hopefully smoother next time.
