guys and girls,

i'm new to this forum but not forums. i'm also not new to motorcycles but i am to chain driven drive trains. weird right? i'm a harley guy and the only bikes i've ever owned are belt driven bikes. i'm not keen on the chain lingo

my girlfriend recently bought an 07 honda shadow spirit 750. its her first bike but she isnt new to driving them. she bought it off her brother, who recently pulled a link out of the chain to tighten it up. i thought that was weird cause i figure, if you pull a link out, its time to buy a new chain.

well the other day she was riding her bike and complained of some noise. so i had her take it for a slow ride around the yard and i noticed the chain was loose. it probably had about an inch or and inch and a half of deflection. i told her to drive it to her brothers house and have him take a look at it. she got there and her brother and biker buddy's said the chain is tight, probably too tight. which is weird cause it was obviously loose to me. but one guy said she needed a new chain for sure.

questions

will a worn out chain do that? tighten up as it heats up?

do i need to replace the sprockets and chain or just the chain? i will look at the sprockets for wear

what size chain do i need? i read online that stock size in 525x124. but i also read that its 525x122 on some forums. not sure what those numbers mean.

any help or knowledge will be greatly appreciated. thanks in advance

ok, thanks for the info guys. appreciate it. unfortunately she doesnt have a lot of cash to replace the sprocket as well as chain but i'll get that worked out.

i need to count the current chain links before i order a chain right? same thing with the sprocket. i have no idea if the drive train has been modified or not

thanks again. think i have an understanding of whats up now. may look into the 38 rear sprocket. she might be interested in that

just to update. i was looking at sprockets and chains......120 chain for a 39 tooth rear sprocket, 122 for stock. which is a 41 or 42 tooth sprocket. since the stock kits are cheaper, i will order the stock kit. thanks once again.

ok. you're making me reconsider. since my girl and i do live 2 hours apart, we do drive our bikes long distance to see each. where did you guys find the 525x120 chain? i talked to motorcycle super store earlier hoping they could hook me up, but they came up short. dude mentioned i should go to a honda dealer to find the chain i need.

also, she needs front brake pads. i've never done motorcycle brakes before.....can you get the discs resurfaced? any suggestions on brand?

 

[maachine]

and that is one hell of a bike bowserpup.

 

[maachine]

ok will check ebay for that

i got on amazon and bought everything separately. including brake pads, it was 122$

i got a JT 17t front sprocket, JT 38T rear sprocket, and a volar 525 x 120 o-ring chain

i did see on amazon how a lot of people commented on the 38t sprocket. no noticeable loss of torque but much better highway manners. people love it.
