After fiddling around with the cam chain tensioners, it was time to refill the coolant system – something Aprilia say to do every 2 years and MotoA has successfully neglected for almost double that! The handbook says to use either Agip Cool or IP Ecoblu. While Ecoblu is still available, the Agip coolant has apparently been superseded by Agip Permanent Plus and Agip Permanent Spezial ….. and wait for it ….. they’re about to be rebranded again as ENI Antifreeze Bike P and ENI Antifreeze Bike S. So which one do we need for the Capo? Well the ENI website says Bike S, while AF1 recommend Permanent Plus (Bike P), so I ordered Permanent Plus before the headache-of-confusion got any worse!
What’s the difference? One is blue and one is red …….. but it goes a bit deeper than that! I must admit that the heady and scintillating world of antifreeze has past me by for most of my adult life, my knowledge pretty much stopped at – it’s green (mostly) and it stops my engine exploding into an ice block during winter-woolly-wearing time. Oh no, it seems that is most definitely NOT the end of it, our aqueous boffins have been brewing up a positive Smörgåsbord of antifreeze variants and as you can guess only some are suitable for our precious two-wheel companions. If you want to fry your brain with antifreeze techie stuff, have a read here. Otherwise it simply comes down to the difference between the two Agip products – Permanent Plus (Blue) is hybrid technology and good for 2 years while the Permanent Spezial (Red) is OAT (Organic Acid Technology) and good for 5 years – hence the ‘long-life’ tag.
But in the end, whatever you buy just make sure it’s good down to -40c and nitrate free and pre-mixed or mix it to a 50/50 solution. Remember that over time the corrosion inhibitors will be used up and the solution will slowly become acidic. Consider buying a PH tester for a couple of pounds/dollars to check the PH level in the radiator when doing a service, ideally it should be 8 or higher when new. If the PH is below 7 then the coolant definitely needs replacing before the acidity starts to eat away at the engine.
So now the Capo has had a nice flush and refill with Permanent Plus and the spreadsheet has been updated to give me a gentle nudge when it’s due to be changed again, rather than the fill-it-forget-it method I’ve used to date!
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…….
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! 🙁
It’s been a while since the Capo was serviced and one job has still remained outstanding – in fact it has been ‘outstandingly’ outstanding for the past few services since I lost my old 
First off, what kind of vacuum are we looking at from the Capo motor? From measurements, it looks to be somewhere in the range of 22-24cmHg (based on an erratic Carbtune II) per cylinder measured against atmospheric pressure …. Now that’s not much for a mercury manometer – barely the length of a sheet of A4 paper. A nice compact manometer then, except that unfortunately mercury is almost impossible to get hold of because it’s deemed way too dangerous for us potato-heads to use safely. So what does this mean in terms of manometer height if we use liquids of a lower density? Well…..
In the flush of youth I was the same as most fledgling bikers I guess, spending endless hours cleaning my bike with mates over a cold beer and loud music ….. of course all that changed when riding a bike became a job five or six days a week. Washing the bike turned into a chore, something to be endured not enjoyed through endless ice-cold winter weeks, honed into a slick process to illicit the most benefit from the least input.
Stop the Bus (or your Caponord) and grab yer smartphones again, TuneECU has just been updated to V2.2 ………… worthy of mentioning? Oh Yes! Alaine has addressed the poor connection (cable) AND the screen freezing if you swiped it when logging issue. Now TuneECU connects to the Capo quick as you like, just as it used to. I tried it numerous times and never once had a problem – fantastic! All-in-all a positive step forward …..
While the weather’s been holding up, I decided to wheel the Capo out and give it a wash. As I soaped, sponged and lathered my way down the left hand side something caught my eye and a hollow feeling opened up in the pit of my stomach ……. something broken or rusty? No, worse – the bloody (road) tax needed renewing!
Connection was the same as before and data is still slow to update – tacho and TPS seem quick enough but the side-stand takes a whopping 5 seconds to change state. Still no side-stand or Fan status indicator like the PC version. The datalog facility worked, but seems to have a bug, more on this later.
What good is a motorbike or a car for that matter, if you don’t have a road to run along?
