Yamaha blaster extended swingarm

[xxsadisticx]

Hi guys, I'm looking to buy an extended swingarm for my blaster

I don't know what size chain to buy, and was hoping someone could tell me. Is it worth changing my sprockets too?

EDIT: I want to buy the +4 extended swingarm

Thanks

well I recently got a plus 3 swingarm and got a good deal on an rk mxu chain, 120 links. I ended up shortening it to 102 links so my guess would be you need 104 links

It is a must to change the sprockets if you get a new chain.

They should be a matched set, the old sprockets will tear the new chain apart.

Okay I've tried searching the forums, what size sprockets should I buy?

13/40 is stock

14/40 for a little more speed and little less take off

what size tires do you run in the rear? That will also affect your take off and top speed.
