Does anyone know of a good machine shop on the Gold Coast or the south side of Brisbane. Thinking I will get the standard 103 cylinders taken out to 107.

Be interested to see what it costs you to get them done, compared to just buying the 107 barrels.

Keep us posted mate.

Cheers

to be honest I haven't priced new ones

is it really worth it, is the gain you achieve worth the money that you spend doing it?

I have been looking at the S & S 110 kit and the best price I can find is thru J & P for $1132 USD posted. How does the other kit compare China and any idea what they charge for post.

all good mate all info is good. I have spoken to a shop on the Gold Coast called Karupt Kustoms and they reckon with the heads and cams I have the S & S kit when matched will give nice results. Not sure if they dyno tune or not but I have a bloke I've used before who is great.

I've alway's thought, resizing used barrels, better than using new barrels. but when the stock barrels get taken out to larger bore, they get a bit thin, the new style of beefy bore linner then tapper it off at bottom to fit a smaller case hole. allow's you to have a thicker cylinder linner , that I would expect would hold it's round better. So i think thats worth looking into as well. a good machine shop that has top equipment and top operator getting hard to find, but they are there or here in Australia.

I have to think about how I want to go with it now. I got onto a local shop and they can supply the kit plus the adjustable push rods, cam bearings and oil system upgrade with fitting and dyno tune for $4500. Certainly more than I first thought but I only want to do it once.

Should cost about 400$ for cylinder boring, probably 400$ for pistons, find a car shop for work, alot of bike shops send out

I looked at a set of big bore s and s barrels, they look like the way I would go personally if I was having a big twin resized.

We can do

Steve if you haven't settled on any one yet give Fred at Pro Cycle Dyno a go up at Slacks Creek .

I'd get new 110 cylinders, 10.5 comp pistons and some mild head work with bigger ports done locally. Run with s&s 585 cams which it sounds like you have and it'll rip. Even without the headwork you'd have gobs of torque just without as much. 

I already have the SE heads and the 585 cams. As I put in a previous post the kit and push rods are $2k. They recommend the oil kit as it makes it more bullet proof. They want $1k labour to do the job which seems fairly reasonable. They will do whatever I want as well but they said with the oil system upgrade the engine will be able to take more punishment. The oil system they use is comparable to the S & S kit which costs $1800. I am still open to suggestions though.
