My stock dtr would top out at 60 on stock brackets. That wasn't quite max revs but with all the noise I didn't dare

@Calum sorry calum my bad, the cylinder head is 3bn y-4

[Calum]

@andrewj1680 Yeah that head is restrictive.

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

[andrewj1680]

@Calum thanks again, is modding it just on the squish band or is there more to it than that?

[Calum]

@andrewj1680 It's a specialist job I'm afraid.

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...

[britshgigolo]

i had mine done by mick abbey last month was £35 turnaround was 3 days not had time to fit it yet as work is still manic

[Calum]

@britshgigolo Should upload a photo so we can have a ganders

[andrewj1680]

Ideal probably cheaper to get it done than get a replacement as I can't seem to source 1 and fowlers want £325+vat not the price I wanna pay as I plan a 200 build during the winter anyway

[Calum]

I remember once upon a time, they were easy to get ahold of.

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

[britshgigolo]

sorry could not find the pictures on the comp so got some new ones

[Calum]

@britshgigolo And this was a 3BN?

Wow that looks wicked now!

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

[andrewj1680]

Thanks lads I've just messaged him to do what he can with both the cylinder and the head possibly just get the bike to him to fit and sort the zeeltronic ignition too

[britshgigolo]

yes with the squish band seem to have lost the original photos where i had them side by side

[britshgigolo]

@Calum cant wait t get it fitted normally work dies off over christmas but not stoped yet hoping for a week off at some stage to get it all fitted
