<![CDATA[Sprockets]]>Just wondering what size sprockets people are running I'm currently running what I believe is standard 16 teeth front 57 rear, bike seems a tad on the slow side and struggling to hit 70mph down hill 😂😂

Wow that looks wicked now!

Really nice squish band. That's going to make a nice difference.

If you give it to Mick Abbey, you'll get better than OEM as he tunes it for performance anyway.

It's more complicated than what I know.

Mick Abbey did my head for about £35 a few years back, I'm sure someone here had their 3BN done recently. Or you can pick up a 3MB Head, but they seem to be getting harder to find these days...

Either derestrict the head, or grab a 3MB head and you will see noticeable gains.

What code is you cylinder head?

Could be wrong. As far as I'm aware it only had the exhaust restrictor, my zeeltronic should be here next week if all goes well but I'm sure the 3nc-00 cdi is unrestricted so possibly won't make a lot of difference
