i have an mc21 thats just had a rebuilt and runs beautifully, well it did for the first few hours anyway. Then it started having power loss at about 6k rpm, and then when i turned the high beams on the bike felt like it had no power at all for about a second until it came back. For the rest of that trip home the tacho would little fits and the power would come on and off intermittently.
Im thinking this is why the mechanics gave me a brand new battery
They said the old one was completely dead when they got round to fitting the new parts ( bike had been sitting in their garage unused for about 2 months).
So the next day i bought myself a multimeter and i got these readings off the battery:
No keys in bike - 9V
Key in bike, turned to "on" but not kick started - 4V
Bike at 2000rpm - 9.35V
at 2000rpm with parkers on - 8.4V
at 2000 with low beams on - 8.6V
at 2000 with high beams on - 2.6V
however with these reading s the bike seemed to rev OK.
I then went to kick it into first to get it back into the garage and it did the crazy tacho thing for a second and died. Each time i started it, it would go perfectly in neutral and then die as soon as first was kicked down, all this with the clutch held in fully.
Needless to say i am completely baffled as to what i should do, but u guys seem to think most things are user servicable, so any advice is welcome.
Cheers,
Tim
