2 issues starting and running
 

firstly my bike wont start.

for a month now when the bike was cold it would struggle to start but would just turn over. however as of the other day it wouldnt start and i had to jump it, then when warm it was fine, and now from yesterday it has stopped working completely and im having to bump start it to get it to even work. reading 13.5 volts at battery, and then 12.7 on the starter but it just clicks. took the motor apart, brushes are worn but still touching, cleaned the copper up and nothing.

secondly the revs are surging.

this has only come about since my 33bhp washers have come out, its find higher revs, and sitting at say 70, but lower revs cruising along it surges. and also wont tick over properly, cuts out easily, i cant find an air leak, so im getting stumped by it, when i am handy on the bikes, but its getting on my nerves now, and dont really want to take it to a shop,

thanks in advance

Would help to know what bike you've got.

Do a proper charging check - it sounds like you've got a duff battery. A correct diagnosis will be needed.

Surging may be simply poor balance.

ooops sorry its a 2000 sv650n. and okay thanks i think ill get them sorted

Re: 2 issues starting and running
 

rectifier has gone i think 20.3 volts at the battery at 6k revs. :o

never know that could cause the misfire

Re: 2 issues starting and running
 

That's buggered then.
Electronic things can do strange stuff when the voltage is wrong.

20V+ will duff a battery pretty quick too.

yep sire is bad. mates got a honda one, looks the same, so going to look into it and give it a go.

Re: 2 issues starting and running
 

ive got a honda ft500 same as honda bros 400 regulator. wired it on and works, but bike at 6/7k revs kicks out 15.3 volts, is this too much? and the wires get quite warm?

is it probably not coping? im flat broke after insuring car so cant afford £45/50 for anouther one at the moment :/
