ST2 heads
 

I'm sure you may have seen the articles about the bloke (tho I suppose he's a 'guy') in the states who had headwork done on an ST2 so it finally produced 100 bhp plus.
I'm looking into the feasibility of doing similar .. anyone know who may do this kind of work over here? :devil::devil::devil:

Do you mean this guy?

American two valve tuning guy

Looks like he's getting nearly (but not quite) 100 bhp out of air cooled two valvers with porting work, zorsts and FIM chips etc. This should be even more achievable with the ST2 since the water cooling prevents the heat dissipation problems on the rear cylinder of tuned air cooled motors.

I had an interesting chat with Neil Spalding at Sigma about this when he showed up in the bar at Mallory the evening before our DSC trackday. He reckons that a 100 bhp ST2 is do-able and that the resultant engine gives you exactly the same engine characterisitics, except loads more of it, everywhere in the rev range. He says he prefers the power delivery characteristics of the ST2 engine to his own ST4. It seems he's also been looking at two-valvers recently because this Monster has just appeared on the Sigma website

I must admit there's the non-conformist streak in me that says "yeah, a 100+ Bhp ST2 as a sort of Q bike" but then I think that for the sort of money that we're undoubtedly talking about (when one of their 'two valve big Monty set-ups and services costs £695 PLUS parts without any tuning being done) I could just stop dicking about, get an ST4s and give myself 120 bhp, upmarket suspension and a carbon hugger without any fuss! Plus, of course, if you then wanted to go mental with tuning bits for a 996 lump there are a lot more bits available and more people doing it - ST4SPS anyone?

Ducati have now made that conversion obsolete with the release of the ST3-103BHP!

Only if you can afford a whole new bike Monty

there was a guy who use to do my mate Marios 906 Paso heads on his drag racer, the guy was also well known to the supermono boys, just can't remember the name at the moment. Hopefully it will come to me and then I'll post it.

Got it, it was Mez Porting

Heh THAT whole new bike would be nice .. mebbie in time a px for the ST2 (if not too old and decrepit by then) may be in order.
Cannot help wondering if any parts are retro-fittable (never did like the st nose).

I havent met anyone who likes the current ST nose, including nearly every owner. Good news from Monty is that it's a straight swap - at a price. There won't be many on the secondhand market for quite a while.

For me, they've made it too 'tourer'. Just a bit too wide and too high, but hey, better than the current one.

Cheers Skidlids. They're in Milton Keynes too. Hmmmmmm.

I wonder if they have made it so you can take the lower panels off without taking
off the top part.:D

By the look of the photos, the answer is no!
DOH!
:yawn:

Hmm looks like mezporting may be the wat to go too .. by the looks of things the st3 heads do fit but require new cams also .. knowing Ducati that sounds damn expensive.
