| You can take a multi-meter and check the output from the regulator/rectifier as they are prone to failure - ecpecially the early ones. They don't always completely fail - they will give out some voltage but not as much as they should.
Simply put the meter across the battery terminals and start it up (although this means taking the right fairing upper off - sorry). The voltage should be around 12.4 at 2000 rpm and should rise to 13.6 at 5000 rpm. (I think I've remembered the figures correctly - everbody feel free to correct me).
If you're even half a volt down, then it's partially fried and you may be left stranded half way through a ride. They are pricey to replace - around £150 + VAT plus fitting although they are very easy to fit yourself (nose fairing off again - sorry).
Also make sure that the temperature read out is working fine on the dashboard and that the fan comes on when it's left running to get hot.
Both these functions are governed by temp sensors - one on each cylinder - and these also can get a bit ropey when old. And they are around £50 each.
On top of that, just make sure all other electrical functions work - Italian wiring & connectors are still made out of a sawdust and pigeon **** composite and are bloody awful.
Other than that, it's a great and under-rated bike as long as it's not been abused. Good luck and let us know how you get on.  |
