MMW head - will it cure my problems?

[Jimmy D]

I'm having all kinds of leak issues with my standard Polini head... would the MMW one with O-ring make my problems go away?

And if so, is it this one?

Or this one (cheaper, but apparently based on the MMW??)

I'm sure either would be fine but the Evo 'head has good reports so I'd go with that.

Thanks Juan - looks good. I did like the O ring design on the Malossi but will take your word that this has good reports and hopefully won't leak/warp.

Interesting fact - the new Polini head needs long-thread spark plugs. First smallie head to use them?

[swallow]

nope, my m1 copy uses long reach plugs, as do lots of other kits I think
