I wouldn't jump a Lithium battery if I were you. They can explode and release noxious fumes!

finally sorted nothing wrong with the bike two knackered batteries both under a year old amazing amitidly the first one was non branded one. won't make that mistake again the second one a shido lithium six months old won't start the tuono. just bought a yuasa uprated battery from ap fire's up sweet as a nut. as for lithium batteries I wouldn't give you the time of day for them that's two I have had now had one on a R1. a couple of years ago soon as the temperature dropped wouldn't start I know everyone bangs on about them. but I'll stick with the lead acid ones.
