Do you like the way the valves are opened and closed regardless of how many valve clearances you have to do :?: :lol:

I like the Desmo valves... engineering elegance... I note the new Monster has conventional valve gear... the Ducati guys are up in arms :lol: :lol: :lol: they have dropped the Desmo and Trellis frame on the new model. The purists are horrified :lol: You cant have Desm and cheap servicing though...


Build-up of the engine commences… The tool for holding the flywheel is essential. This one is home made, but they are cheap anyway. When people say wedge a penny in the gears I cringe!

One important thing to remember is there is one special bolt in the cases that acts as an oil feed to the LH case. This needs to go in a certain hole!

The bottle of oil is strategically placed... I am so ashamed of the welding on that engine frame! :oops:

I had a little help bead blasting the other day! :thumbup:

Did that quite some times in the past. A piece of cloth is often enough to block a gear pair.
The downside is that you could rip both of them through that "mill", if the torque is high enough which puts a lot of load in your bearings/shafts. Don't ask why I know and where these perforated rags in my garage come from....

Meanwhile I do have a cheap, easy and secure method.
Usually you have a spare engine and if you have one gear that'd engage in both other gears, it acts as a perfect lock. If the engine lacks design space, you could cut down the 3'rd gear to a half or smaller piece, just that's it's big enough to engage with the others.
Saves you building individual lock tools all the time...

Funnily enough I was planning to do this to lock the crankshaft in place when I service the Tuono in a week or so, but of course you would need two sections of gear to stop it rotating in both directions. I plan to cut an old gear in half and make up a bracket to fit them on both sides of the primary drive pair.
It's not falling off, it's an upgrade opportunity.

I did read recently about the Monster having conventional valve gear, but I didn't realise they'd done away with the Trellis frame on that model 8O
I bet the purists are up in arms :)

I don't like the idea of wedging gears with a penny or a rag, especially when some of those flywheel bolts have such a high torque value, but I know it happens.

Interesting to hear about the special bolt that acts as an oil feed 8O

I like the way you're bringing on your little helper :D

There is something satisfying about doing the hydraulics. I pulled everything apart and gave it all a good clean, bead blasted everything and put it all back together with a smear of rubber brake grease and brake fluid. I didn’t replace any of the rubbers on this build, all seems to be in nice condition, so they just got a quick wash in methylated spirits.

Last update for a few days... I will be 66 tomorrow... a Pensioner! :mrgreen: Another milestone reached! My wife is treating me to a few days away and we have family things planned!

thanks for the birthday wishes!

I took a good look at the forks, and while the sliders were perfect, the anodizing on the legs was past its best. I popped them in the lathe and used some 240 paper to remove the anodising, then followed it up with some 800, and then a polish. they came up a treat! I did consider re-anodizing them but there is so much to polish anyway! I fitted a couple of new seals, and some new oil. all in all not a difficult job!

They look great 8)
The lathe must have been a big help in getting that finish,

Started the rebuild of the engine… a tip I picked up years ago is its sometimes best to pop the piston in the bore with a ring clamp from the top, and then push it down far enough so you can get the piston pin in from the side… this saves broken rings and that’s important when a set for one piston is over £200! Put some rag in the open crankcase before putting the circlip in though!

Good tip on fitting the pistons :thumbup:
I can see why you would want to close the openings into the crankcases when fitting the circlips :wink:

I couldn’t resist modifying the clutch cover… I guess that the clutch is going to be even more noisy now! :lol: :lol:
