You may (or may not!) have read the post a couple of months ago – Fixing a few Capo niggles. That was where between Continental trips, the original air-box molded connection for the crank-case vent was drilled out and a new 90° bulkhead coupling and 
pipe fitted to drain any oil into the front of the airbox, well away from the throttle body and IACV (Idle Air Control Valve).
Now with the Caponord seriously (+1,000 miles) overdue a service, I got stuck in and removed the tank ready for plugs/air filter. I admit to being really pleased to see no oil what so ever in the upper part of the airbox and only a tell-tale smear in the front section. A syringe sucked what oil there was from the drain tube – approx. 5cc @ 3,000 miles WITH the oil tank filled to the HIGH mark.
Previously it didn’t seem to matter where the oil tank level was, oil kept getting thrown into the airbox and sucked down into the throttle body. Look closely at the design of the airbox and you see the ‘fenced’ in area (red) around the velocity stacks – and of course, the two slots in the stacks (arrows) for excess oil to drain through.
It’s pretty obvious then that Aprilia/Rotax EXPECTED regurgitated oil – and tried to ensure it was fed back to the engine and burnt. Unfortunately that isn’t always the case and when some bikes are left on the side-stand oil manages to get over the ‘fence’ and muck up places it shouldn’t!
Of course a little hot oil can spread a long way and look far worse than it really is ….. I guess it just niggled the hell out of me each time I lifted the airbox lid. In hindsight it’s one of those quick jobs I wish I’d done years ago.
With just over 82,000 miles on the Caponord, the dashboard died. Yes, while about to set off from a rather innocuous little shop car park on a hot and humid afternoon, the dashboard shuffled off its mortal coil … Curled up its toes, bought the farm – as dead as the proverbial Dodo.
The Capo and I just returned from the last UK-Italy round trip for this year … as seems the norm, the trip was uneventful and the Capo ran fantastic as always. Just before I left the UK, she had a new MOT – no advisories and good for another 12 months. 48hrs later, she rolled into the barn with the odometer reading 80,892 miles and 37c on the air temp gauge – hot, hot, hot!
A good few year back when I had a Triumph Trophy 1200, I had an issue of excessive noise from the chain/sprockets – especially on the over-run. They were almost new and as far as I could tell, it was correctly tensioned. It drove me mad for a week or so, until I decided to try changing out the front sprocket, why I can’t remember, but it worked.
The only difference I could think of is the make of sprocket. I’ve always used 
Secondly, and I don’t mind admitting when a change to the Capo doesn’t work – I’ve gone back to the #60 clutch oil jet from the #40. Why? Simply because the benefits were outweighed by the losses …… yes the #40 jet made the initial 1st gear selection go from ‘CLONK’ to ‘clonk’ but it also buggered up all subsequent gear changes, gone was the silky smooth shift that I’d had with the #60 jet. In the end I would say that if your Capo shifts gears smoothly and doesn’t have an issue selecting Neutral, then leave well alone. I’m sure for those with no jet, a blocked jet or a nasty gear shift this may well be a worthwhile modification, for me I’m glad to have the old slick-shift gearbox back again.
And lastly, the replacement rear sprocket and 
Well yesterdays arrival of a spanking pair of Michelin Anakee 3’s makes the total number of tyre types fitted to the Capo a head spinning …… 5. The OEM fit Tourance, oodles of TKC80’s and Karoo 3’s and one fantastic set of Anakee 2’s. They were by far the best with excellent grip and long life – so the Anakee 3’s have a hard act to follow, I wonder how they’ll compare.
