go up one tooth on the front sprocket

Here is a handy calculator that you can use. Just change the tire size and sprocket size and you can even change the rpm’s.

It will tell you the speed for every gear.

thanks for the link really help decide what i wanted to do so if i just go up one tooth in the front do i need to order a longer chain or will the stock size still work

[lester985]

your chain will work

No the front sprocket is so small it wont make enough deference. If the chain and sprockets are very old you should change both sprockets and chain at the same time. The new sprocket won’t last very long if you use an old chain.

i was goint o order a chain any way just needed to make sure the stock size would work

Most chains come with a few extra links and you will have to cut it to fit.
One thing I can tell you is to get a few extra master links, those clips seem to want to fly off when you put them on, never to be seen again.
