Question for technical type peeps.

[Zimma]

Right, nice and simple... What I want you to do is take a look at the rear cylinder in this picture then....

https://www.abercon.co.uk/~neilr/pix_bits/enginecut.jpg

At a guess, how much would I be able to bore that out by, safely?

Then if not could I, and if so, where would I be able to get some new barrels machined up?

Thanks

I wouldn't bother mate, there's bits missing. You'd never get any compression for a start.

Oh god Zimma, please tell me that isn't your actual engine. From what I hear things of yours that get taken apart have a habit of not getting put back together

Anyways, best bet would be to talk to Kev, although he might just point you in the direction of that bloke he knows from Big CC Racing.

From the picture it's hard to say exactly what you could do, but I would say about a +60 overbore should be possible without serious problems.

You would then benifit from getting the head machined as well so that flow was maximised (starting to cost lots of money at this point though).

[robby mode]Just forget the 'storm engine. Just buy a Triumph Rocket III, 147ftlb of torque and accelerates at 1.2G[/robby mode]

Sorry, I just read it in MCN and was impressed with the figures.

Zim, just go buy a better bike, much cheaper. Why bore the thing out, it's only more likely to blow on ya get those high compression pistons, Turbo, Supercharger and NOS.

Na, GSXR1100 would suit Zim more, he wants something to fuck about with

Imagine how much weight and simpler that engine would be if it was just a 2 stroke,

Hi

Doubt you could bore it out much. Is it a plated bore or does it have a seperate cast liner?

By the way, Gav was showing his age by referring to thou, ie, thousanths of an inch. 60 thou is basically 1.5mm.

All the best

TTS Performance only advertise a 1mm rebore on their website, and that keeps(?) the engine capacity at 996cc.

Hi

Any decent engineering shop could machine you up a set of barrels. Price might well bring a tear to your eyes though.

Probably worth talking to TTS and seeing if they know of any alternative barrels for sale.

Anyway, for torque surely you want to stroke it rather than boring it out.

All the best
