and what rockers are they?

Just scored this off an old friend who had it stored in his garage for a couple of years...

but what head is it? got a little bit of porting, 2 J7??? and 4 bolts along the front?





still trying to take the head off to check chambers... but the nuts are being a wee bit annoying (any help with that one too?)

Late model small bore Polution type head

nothing wonderful really

It`s just a late , tiny little port cyl head off a 998 designed to have all the anti polution type crap on it

Thanks Matty.

What are the rockers on this head?

C'mon guys, you get what you give, so don't keep the wheel of karma spinning... just chill hey

Matt, seeing as how there has been half a dozen posts here none of which are relevant to your question I'll say that it looks like a late model polution head,,, maybe A+... can't tell you anything else but maybe some one else will now that its back on track.

A+

They are the same rockers fitted to the polution motors in 77/78 in Australia.
So they may be fitted to A+ but they were fitted for a few years before that.
The head and the rockers look like late Aussie Mini 998.

As for GT Mowog....

So are these rockers superior than the pressed metal type and interchangeable with earlier motors?

The only way they are superior is that they were cheaper to make.
The general opinion is that they are not very good.

They are rubbish really, when they wear you cannot rebush them like all the others, as there ain't no bush! They are sintered (hot pressed iron powder) and run direct on the shaft.
I have one at work off a 1275 which wore so bad the rocker broke in 1/2 through the bottom. The shaft wasn't pretty, either.

Hey no worries. Don't forget the Doc and Morris, they answered too.

And our answers were even correct.

I'm pretty sure that you said the same thing I did,, except you knew that they used those rockers on late pre A+ motors..
