That anti-rattle spring is how Graves fixed the 2009 R1 clutch.
Yep, I usedthe 08 spring plate on mine to fix the ridiculous grabbyness. worked brilliantly.
So after riding it a bit including down the coast and back, and some 2-up riding, I can give a verdict.
I think OEM plates are better, tbh. The Barnetts are grabbier and groan a bit when taking up drive (which is probably the anti-rattle spring), and the anti-rattle spring doesn't really reduce the rattle down more than the rattle is reduced by just replacing worn plates with new ones.
That said, they're cheaper than OEM and the break-even point so far with me would be getting these plates out to about 18,000 km . (Though I'll be doing fewer trackdays on them than I did on the OEM plates).
Jury is out as to if they're recommended. I'll go OEM next time along with a slipper basket and pressure plate to suit the OEM friction and metal designs.
I used Surflex in the last dry clutch change and found these to be bloody good. Also recommended by Ian Gowanloch. Even though my stack was within tolerances with the springs, steels and dive plates the correct thickness and basket and hub in reasonable condition, my OEM clutch would slip, something was obviously wrong in there. Changed to the Surflex and all was sweet. Very easy job to do on a dry clutch.
You can get enough wear on the face of the pressure plate that you gotta shorten the pushrod to stop that slipping, so that can be an issue. I have played with the idea of making a variable length pushrod (which you set with a couple of set screws); my vented pressure plate sits at a different height to a stocker, which is another aspect to consider.
Might try surflex next time. These aren't annoying enough to swap out at least .
Smashed off a few hundred KM today with Charlie, all good.
A few days ago I noticed I'd lost the sidestand front bolt (they vibrate out, is a common issue - and yes, that's even when loctited in). I didn't have an M10x1.5x25mm capscrew, but Charlie did so that's all good. I'll order a few more spares.
Until we had sorted that, I just leant it against things. It still stands up with the stand only held on by 1 bolt, but it leans over A LOT. As in, it almost lifts the front wheel off the ground when you put it onto the stand...
The other thing we sorted was a pesky issue with the Spark midpipe I installed a few years ago. It fatigued the stainless springs at their mounting hooks, no biggie, just replace them. However, about a week ago, I lost another one... this time, the damned lug came off the front slip joint on the horizontal header pipe!
Thing about the Spark midpipe is that it only has a slipjoint on the horizontal pipe for making postage easier, so we just TIGged it all nice and solid. Did it in situ, which meant access was an issue.
No dramas for our team ghetto skills, though.
Yeah, guess I might need to replace that rear sprocket. If you're gonna do it, do it properly.
Nearly 40,000 km, a shitload of trackdays in those km, yeah, not terrible life. Actually did it a few weeks ago, on the last ride pre no winter rego... just got around to checking it now.
Chain is super stretched which is why it's had to break the teeth. It's about 1.5% stretched, which is a lot for a chain.
Christ, nobody can give you shit for not getting the most bang for your buck in that sprocket....
Yeah ideally one more day would have been good. You get heaps of warning as the chain stretches bad enough to result in wear like this (I adjusted it a lot in the last 1500km) and, well, maybe i could have ridden more sensibly.
Probably shouldn't have procrastinated about what rear sprocket to get, though.
Either way, it lasted a long time despite abuse.
Did that just get missed or what? It looks like it should've been ditched a few thousand ks ago.
Is it a Supersprox? I would've thought itd last longer, the R1 is on oem sprocket thats been abused and rarely lubed, and its lookin fine at around 37 or 38k kms compared to that mess lol
Just over 40,000 km, and yes, a supersprox (the only other choice are quick change alloy ones and they won't last that long at all). Given the track life of the bike, no, it's not hugely surprising to have it that unhappy.
Maybe a week or two less life would have been fine . The stretch in the last week was rather dramatic, which is actually what does it (rather than any other aspect of the sprocket).
New bars as a christmas present.
Wanted lower rise than the standard (already low) Maguras, without going to clipons. So here we are.
Nice, Merry Christmas. Saw you riding out from Belco Mall area the other afternoon about 2.15pm.
Might have been Em on it, I've been away and didn't ride it once I got back from the US.
Ok, didn't get to see much, just the Silver Monster and rider with Silver jacket.
How'd the old bars fair?
They're still usably fine, and the Rizomas were even roughly the same price as the standard Maguras (well, these were slightly cheaper thanks to someone not wanting them for a project). Good time for a change and good excuse to put the stock ones in the box of stock parts.
Plus they match the 7/8"s non fatbar Rizomas for another project.
