Had a few issues with my bike. Specifically with play around the pivot bolt of the side stand. Turns out that the two holes in the CDT carbon stand had been drilled out of alignment and also were slightly oversized, resulting in a noticeable amount of axial and lateral free play. Decided to have a new rear bolt machined up and the front one was sleeved and turned down to match the diameter of the new rear one. The holes in the stand were reamed to match and as a result re-aligned. The new/re-engineered parts now have a tolerance of only 5 thou and there is no free play evident. Job done. Whilst at it, I noticed the stand had some damage to the lacquer where it snaps up and contacts the bracket. The bracket also had damage to the paint/coating. The bracket was re-coated save for the contact areas where the stand touches it, both at full extension and fully retracted. The stand was also re-lacquered and the protective film re-applied, only this time the film also covered these contact areas, as well as the main area where your boot would contact it during normal operation. Finally CDT use a very soft aluminium sole plate which was not really up to the job, so I had a 3mm stainless steel plate made up and profiled to the shape of the original, which was then bonded into place.

I also had some issues with my Renthal alloy sprocket, which despite being correctly aligned on the quick change sprocket carrier and the chain correctly tensioned and lubricated, was just being eaten away, after I first noticed small alloy shavings coming off the teeth. Decided to cut my losses and go with a Supersprox steel/alloy sprocket and CNC Racing flange, so I would get the best of both worlds. Longevity and lighter than stock weight. Odd though as I have never had issues with Renthal products before.

It has been asked a few times, what is the purpose of this bike?

The mods and stuff look great, but then I see mirrors and a kick stand. :confused:

It's an exercise in self indulgence Chaotic. I used to track my 748SPS and 998S but lost my appetite for the repair bills, running and transportation costs. My cervical neck injury put pay to it all ultimately, so now I just enjoy the satisfaction of having built the bike to my liking and riding it at whatever pace suits me, be that fast or slow. I'm taking it to WDW2016 in July, so a good opportunity to stretch it's legs. Been twice before in 2000 and 2002, but this year is their 90th birthday celebrations, so one not to miss.

Topolino - can you tell me where you noticed the shavings coming off the sprocket? Inside, outside, leading edge or trailing edge of teeth etc. I ask because I have a Renthal carrier that I am about to install. I did do not have the sprocket (went with superlite based on availability here in the US) but your description causes me to be concerned about the carrier being the root cause of a potential alignment issue. I would like to be on the lookout for potential problems.

Thanks in advance

How did you coat the carrier in black? Is it paint, powder coated or anodized?

Its a two part paint coating made by DuPont called DTM (Direct To Metal). You have to use their aluminium special epoxy primer first, to give the top coat a key. It's not too thick so looks a lot nicer and less crude than powder coating, which tends to mask the crisp lines and shape of a casting, as it is too thick. I went for a satin black finish. It's also very tough and scratch resistant. Here's a picture of some of the parts I had done last year. You can also find more info on the primer via this link:

Just WOW! Thank you very much.
 
Those satin black parts do look muchhhhh better than the ugly silver. Wish I could do all that in blue on my bike but that seems like a lot of work takin apart n putting back on since I don't have a stand.

But it would be an amazing winter project :)
And it would look awesome!
Buy something like this chinese thing for 50 bucks and mount it to the ceiling of your garage. That's what I did...

Gecko, these pictures will give you a better idea when I mean no loss of detail, as opposed to powder coating. Anodising will produce varied and unpredictable results, unless you had these parts machined, and is only ever a better option if you are talking about billet parts as opposed to forged castings, which is what these are. If you wanted to go for the ultimate in a finish, you could grind the seam lines off each casting, but they were not that intrusive to me to make it worth the extra time and expense involved and I am happy with the end result.

Looks awesome. I see you went for some Bursi parts :)

Yes. Love his attention to detail and not a lover of the SATO or Ducabike alternatives. He also made some one-off billet suspension links as well, but I daren't ask how much they would cost!

Sorry for the late reply. Only just noticed. The shavings were coming of the front and rear faces of the teeth. We (local Ducati specialist and I) checked the alignment and no issues there, chain tension correct, properly lubricated. The only thing we noticed was that even though it was a 525 chain and the sprocket was a 525/41 the chain had a lot of lateral play, almost as if the sprocket was too thin. I checked with Renthal on the thickness it should be and it was correct, so I am at a loss to see why the sprocket was being chewed up so quickly. Anyhow I have ditched it in favour of a Supersprox setup. Light weight and durable. Hopefully that is the end of it, but I wont know until I ride it come the Spring.

I have just fitted a Renthal carrier etc 15t/42t set up so will be keeping a close eye on it once I start riding it.
 
Thanks very much for the reply on that -I'll not be quite as concerned about the change since the carrier didn't seem to be the issue. I will still be on the lookout for potential problems though as it seems to be a bit of a mystery as to what the root cause was.
