I managed to get a couple more Capo jobs out of the way recently. Firstly, replacing the clutch line for a nice new Venhill version to match the shiny ones on the front brakes. The hose required uses:
- 1x 90º Banjo
- 1x 45º Banjo
- 1x Venhill Powerhose Plus hydraulic line – 1125mm
It fitted perfectly, and while I was changing the line I also changed the banjo bolts and bleed screw for matching stainless steel units to complete the look. I have to admit, these are not cheap lines …. but I love the fit and flexibility with interchangeable ends. So for that I’m willing to overlook the extra hit on the wallet!
Secondly, I bit the bullet on an Innovv K3 dual camera system. As some may remember, I’ve previously tried the original K1 and the much improved K2. Unfortunately, the K1 DVR unit died after 12 months and the K2 turned itself into a brick with a failed firmware update. To be fair to the K2, it was leagues ahead of the K1 and (when it worked) was a truly fit-and-forget system. What went wrong I have no idea, I followed the update process to the letter and even had a few email exchanges with Rock Liu from Innovv, but they dried up when it looked like the unit was unrecoverable. I was lucky enough that the K1 and K2 had been supplied FOC, so nothing lost. This time however, it’s my own outlay. It’ll either be ‘third time lucky’ or ‘a fool and his money are soon parted’!
Certainly my first impressions on opening the box are:
- Slightly smaller DVR with no buttons
- Nice moulded waterproof connectors
- Comprehensive fitting kit with stainless fasteners and anodised aluminium brackets instead of plastic/steel
- Cameras physically identical to the K2 units but with different internals
- Addition of an external microphone
- Waterproof remote button for saving files and taking photographs as well as LED’s showing recording/GPS/WiFi status
Looking through the technical specification, it looks like the main upgrades over the K2 are:
- Dual core processor for better image processing
- Different camera internals ( Sony IMX291 LQR sensor)
Installation was of course, very similar to the K2. The power module connects directly to the battery positive and negative terminals and the yellow trigger wire went to the loom I still had in place that tapped into the rear lights/brake lights. As soon as the side/head lights are turned on there is a 10 second delay before the unit begins recording and when switched off, a 25 second delay before powering down the unit. The front camera comes with a 2m lead which is fine, but the rear has a 1.5m lead which for the Capo is way overkill. I only needed about 0.4m and hiding the rest away was a real pain.
To install the cameras I used two 15mm rubber lined stainless steel ‘P’ clips – the front one on the Aprilia headlight guard and the rear on the pannier frame. The included mounting kit parts fitted to these clamps just fine and it only took a couple of minutes to get a nice neat install and great picture being recorded! Oh but one bit of advice ….. the supplied screws don’t use any washers, so once happy with the install, I went back and put a dab of thread-lock on all the screws just to be safe.
Sorting the rear tensioner yesterday took all of 20 minutes, but I knew that the front was going to be a different kettle of fish altogether because of the coolant pipes. No worries, I thought – a good excuse to change out the coolant as well.
So in I went and oh what fun it was! Off with the crash bars, side panels and sump guard, move the coolant bottle and release the radiator bottom hose and drain the system – so far, so good. Remove the airbox and release the clamps holding the throttle bodies in the inlet rubbers ….. hmmmm – looks like they’ve got a few deep cracks I’m thinking.
Take off the rest of the hoses, cables and electrical connectors, now a gentle pull and twist to release the throttle bodies and ……………… oops! I think the cracks in that rubber were a tad deeper than first thought and a touch beyond repairing with a splash of rubberised goo. Luckily I’ve a spare pair to hand from the l’Aquila stash. However, this momentry inconvenience isn’t the task of the day ….. so onward once more. Hoses, cables anything and everything moved so I could at last get to the two clamps holding the ‘Y’ hose in place – then finally the goal was in sight, the pot at the end of the rainbow …. the front cam chain tensioner!
With a heave, a grunt and too many fingers trying to get into too small a space I managed to retrieve the tensioner from its hide-away, gave it a squeeze and ……… it was fine, solid as a rock! Never mind, a flush to clean out any debris and a refill with clean oil never hurt.
Then it was rebuild time. The tensioner’s in place and the cap torqued down to 30Nm with a swanky new copper washer. The super-shiny inlet rubbers torque down at 19Nm and the rest of course is then a reversal of strip-down – with the intention of NOT ending up with any washers, screws or clips left over! And so with the sun ready to slip behind the mountains it was test-time. Glad to say she fired up first hit of the button and sounded so much smoother, funny how you get used to little noises and ‘character’ over time – now she’s idling smooth as can be, a tweak on the throttle body sync screw had the manometer within a couple of mills AND it stayed that way when the motor was reved, something it didn’t do last week. So I’m guessing the cracked inlet rubbers were an issue after all! 😳 So that’s it for today, other than updating the Capo’s history spreadsheet ….. the Capo has now done a pinch over 74,400 miles and other than a couple of valve shims and plugs, it’s the only work the motor has ever needed.
Next stop – tyres, chain and sprockets. 😯
Yesterday I spent a lazy morning installing a couple of sensors inside the airbox (more in another post) and with the tank propped back in place, fired the Capo up to check the fuel lines…….
…… and just for a second or so after she fired up there was a distinct rattle from the rear cylinder and frankly it didn’t sound too special as the bike warmed up. To be honest, I’d heard it before on a couple of occasions but couldn’t pin down which cylinder it was. With the tank lifted and stood in just the right position, it was obviously the rear. As it was lunch time, I decided to have a look a bit later – and promptly forgot! Well I got back to it in the evening and pulled the cam chain tensioner out. Soggy as a knackered bed spring! 🙁
So it had a thorough flush out and re-charge with fresh 15/50w oil and firmed up nicely (phew!) …. it looked as though contamination had built up in/around the ball that seals the oil in, in this case letting it out just as easy. Buttoned it all back together, fired the motor into life and revelled in a quiet(ish) Capo motor – just in time for a cold beer and MotoGP on the box, bliss! As I sat watching the race I kept having a niggling thought … what if the front one is the same?
Tomorrow feels like a let’s-check-the-front-one day ……….. 😕
