I see no problem with adding more rattle to the Duc.
I wonder if they factor the cost of replacing bolts into the service costs for your year?
If you can get the wheel stanking hot to release the high-temp loctite AND you manage to not munt the torx heads, they come out pretty easily. Only had 3 that were super-stubborn, the rest were just harder and more difficult than the suggested loctite (242) should be.
There's no service cost, those bolts only come out when you want to replace rotors. Based on the fact I got 35k km out of my rotors, riding the arse out of the bike, and still had only worn 0.2mm out of the ~0.6mm between regular and minimum thickness, the rotors are serviceable for quite a long period of time on the bike: I approximate 100-105k km rotor life for the OEMs.
EDIT: note we didn't actually break any bolts. The usual thing that happens with high temp + strength loctite into softish alloy wheels is that you tend to take the aluminium thread out with the wheels. This didn't happen here cause we heated them up nicely with a blow torch, hit them to shock remove the loctite, and used an oversized bit on the really stubborn ones. It worked, just is painful and rendered about 5 bolts (out of 24 - 2 sets of wheels) unusable, all unusable because the oversized bit destroys the head and they don't drive very well. I bought replacement bolts which are allen-headed, simply because they are about the only torx bolts on the entire bike. Saves on tools needed at the track, just in case. Theoretically you can get more torque into a torx headed bolt, but you'll destroy the alloy threads long before max torque on either a torx or allen-headed bolt.
Given the spec torque for these is somewhere around 23-28 Nm (I have to look it up; Brembo suggest 30 Nm in their installation guide), they're not super tight.
Finally: bolts are cheap. Where possible, I don't tend to reuse them. They might go into my bolt bucket for emergency requirements or to size up replacement bolts, but I try not to reuse bolts too often. Carroll Smith (a better engineer than I will ever be, ignoring my lack of degree in Engineering and all) always used to say: "if you ever want to know if you can reuse a bolt, put it in a bucket of water. If it floats, you can reuse it".
stoppies into turn one supa .......... full floater rattle is awesome but the again i,along with you, are a rattle junkie..:bowdown!:
It already stoppies like a demon, the pads made a huge difference (and the stock brakes were already phenomenal). . So this is going to be extra double plus good .
That is a fair level of good. Can't wait to join the rattle club.
Where do you get your powdercoating done? Does it cost much for a set of wheels?
Quote was $70 a wheel for blasting & powdercoating through Capital Powder Coating. They're in Quangers.
There's also ACT Powder Coating, also in Quangers, and I think they will do sandblasting for you as well.
Canfab in Fyshwick are about $50 a wheel but they don't do the sandblasting: they suggest you get AA Sandblasting to get that done first .
Oh yeah, and my wheels were already stripped: no tyres, no brakes, and no wheel bearings. Wheel bearings weren't hard but were a bit fiddly and annoying to do, the spacer in the middle didn't want to flick aside for Brett & they need a reasonable amount of heat to help the bearing come out without destroying the wheel .
Stick em up. This is a thread jack:
I just replaced the pad an discs on the Katoom, and re-used all my bolts. The didn't look damaged when I cleaned and re-loctited them, but have I unwittingly made a booboo?
No, I'm just totally anal AND I had the $4.53 it cost me from Specialty for 25 x zinc coated M8x20x1.25 12.9 button-head allen-driven screws .
Depends what loctite you used though. If it was high strength (high-strength, aka 'red') I hope you really cleaned the threads out with a brush and cleaned out the threads in the wheels. 242 (med-strength, aka 'blue') then it's not so critical.
more personal preference i think Jdeks - He changes tea towels between dishes when he dries up!!
...you dry your dishes??
Often air dry but .
So, brakes are on, they work. Make a fantastic whirring noise as you slow down, it's like enabling reverse thrust. They don't rattle that much either, least I couldn't hear them over the rest of the bike. Worthy upgrade.
Before putting them on the bike, I did a bit of a weight comparison: stock disc is 1786g, these Brembos weighed in at 1358g. Nice. They also look super spanky.
In regards to bolts, yeah, I'm just a bit anal. Plus I did want to swap from torx to hex headed - means it's one less socket I have to pack for the track just in case I need to swap brakes over for whatever reason. The stock Ducati bolts are plain 12.9 bolts but coated so they won't rust, so I went zinc coated 12.9 bolts just to make sure. Dab of loctite 242 (actually 248 - I used my glue stick version), do them to appropriate torque, and it's all sweet.
Also nipped up my steering head bearings, they'd started to get a little bit loose (were replaced prior to heading to EC 12/13 June).
Now to focus on some of the other bikes in the garage to progress them...
Sounds like a win!
Now to figure out how to have the bike let off steam when it settles to a stop... VROOOMMMM! WHIIIRRRRRRRR.... Psshhhhhhhh.
It IS hard to compete with the DucaTabmourine for rattle noise.
Powdercoat + spare rims = bling.
Can't be arsed going to the car to take a pic of the front, but it has the Brembo full-floaters and new wheels bearings and all manner of spiffy stuff installed.
Powdercoating was done for me quickly & cheaply - the rims are perfect for track rims, as they only need to look good for the people watching . I'm happy with the results though, they're nice and bright and red and will look sweet.
Oh and dirty marks are generally from my dirty-arsed fingers from fitting the tyres.
This now should make life easier. Black original wheels = road wheels, and wets when it looks like being damp (like tomorrow). Then red wheels permanently score the slicks .
Bring on El Nino and less rainfall!
A crueller mistress there is not one. La nina appears to be more unhinged, too.
