Re: Battery Drain
I've got the same bike (2005), the same battery (Odyssey) with exactly the same problem.
If it sits 1-3 days, it starts fine. After that, it gets dicey. 5-7 days, probably won't start.
I've got a Battery Tender which I connect if I'm not going to ride for more than a few days. It takes about 3-4 hours to get charged.
I'm planning on attacking this problem this weekend (I'm handy with a meter), so I'll let you know if I find anything.
I'll certainly try charging the battery off the bike. I have a 5 amp charger somewhere - I'll have to dig it up.
2005 BMW K1200LT (got it in July 2007)
2002 Kawasaki Ninja ZX-12R (parked next to the LT)
1982 Suzuki GS-750EZ (paid $500
for it in 1985, sold it for $450 in 2000)
1978 Honda CB-500F (sold in 1980)
1976 Honda CB-400F (drowned to
death in the blizzard of 1978 in Boston)
