Just to update I've had the block done, oversize liners and 89mm pistons. The Yoshi cams are here too. The crankcase has been bored to suit. The Carillo's are on their way too, should be here within the next month. Apart from that progress is slow, Rog Upperton's had the head since last June, but he admits, as hes semi retired, it will be a while yet so, watch this space.
Well that's quite some progress in itself - will def be watching this space!!!
What capacity will that take it to? 1550 ish ?
seems like a nice project coming along nice .. be good to see the pic when you do have any :onya: we all like pic :clapping:
:useless: :lol:
very interested in this thread
may next winters upgrade to the 14
:boogie:

You should have bought boriz's upgrade kit then on eBay ;)
That was a nice kit
i didn't see it or would have :whatever:

Hello Kja , glad to see you here and that your big bore project is going ahead :drool: :drool:
you been bothering stu again. Um 1692 turbo now there's a thought. A silly one I'll grant you
This is where I'll be going when lotto comes in... http://www.ptr.com.au/engine-packages/
Clearly it's significantly more expensive to get 160HP from a 14 than 240 from a b-king.

I think their dyno figures are somewhat optimistic for the B-King, Boris was up around the 180-185 bhp mark with his 1700 kit, which is none too shabby. It can be done a whole lot cheaper than the prices quoted too.

Not recently, spoke to him on FB a while back, its a bit of a trek to his workshop from north Lincolnshire tbh.

It is yes, ideally I'd have liked to have been further on with it, but I'm at the mercy of others so I have to be patient.
Theres progress, a photo of the head inlet stubs after machining...........
Not much I know, but its a start :)
Every adventure starts with a small step ;)
Hope to see the fruits of your trip soon :8:
Accompanied with a Dyno run print out ofcourse :smitten:
KJA, wish i could afford same. a great project mate. i will follow your posts. i would, if i had cash, love a 14 with 170 bhp. just something that needs to done without turbo.
Rog has done another head for John MacLean/Warpspeed, every trick in the book, big valkves 34mm inlets and 30mm exhaust valves, a comptetition port and flow, he says never again though, too much work.

Surely as he's done one it would now be easier and cheaper todo a second or third ?

I'm thinking he means the cost v any real gains, he's spent hours on it, literally, he reckons oversize inlets are possibly worth the hassle, not necessarily the exhaust valves. Will let you kno more when I see him next.
Had a delivery yesterday, the Carillo's are here.......
Oooof...Nice delivery kja :boogie:

You know it makes sense to do it, Seth :mwink:
You'll soon fall behind with a measly 130 Bhp :twisted:
Kja, are there more parts ( except the head) you are waiting on?

i have a very manly 136bhp
i need to win a lottery before i could change much more tho .
if i did it would be internal mods.

I'm nearly there, just some high tensile cylinder studs and nuts and gaskets. I'm on with the gaskets though Cometic will make the head and base gaskets to suit, still sorting the details though. The only other task to have sorted before I start the build is I want the crank/rods/pistons balancing, I'm junking the balancer shaft, I've found a place to do it, just sorting the details at the moment.

Make sure that you'r high tensile bits and bobs are long enough, and that you cant torque them in oem specs (thread stripping is very forcefully present with em, aluminum block vs hardened steel). And if you are going for studs, you have to pull the engine out every time if you want to do something involving the removal of the valve head.
What comes to balancing and Carillos - you can forget about it, they are spot on. Mine had a minute differences with the j.p pistons, and by mixing and matching no balancing was needed.
I was talking to a guy yesterday, he said any gains would be minimal, its more about reliability though, I will possibly end up with the balance shaft back in and not bother with the lightening.
Guys, I have bought a shot 1400 Motor yesterday for 50 bucks ( transmission included).
My plan was to buy and modify this motor while my bike stays operating.
Could you write down a concept inkluding a parts list and list of modifications so I can copy-build this?
There are no kits available I think, so I must follow your wisdom
I will add pictures in the evening :)
I'm sure there are big bore workshops in the UK and or EU. I recall reading about 1 such shop that it's a ride in on a std 1400 & ride out (once done) on whatever monster you wished to create, they did everything in house. So you should have no trouble getting your 'new' engine to how you'd like it.

I have a friend who does my Chevy Small and Big Blocks since 30 years. I want him to do at least the shortblock. These workshops take way too much cash for my liking :)
Try Googling gsx1550 big bore kit, you get quite a few hits on this.

Phil Tainton in Australia was doing 1620 conversions, I don't know much about them other than they were not cheap, and they went real well.
A guy I know on the East coast has one in a drag bike, we had another on one of our group rides a while back.
You could see if PTR want to just sell the parts you want.

There's one around Brisbanevthat the local Suzuki guru / mad professor put together. I think that one is bore and stroke to closer to 2000cc.

You sir are correct.
I am trying to sell my 1402 powered EFE.
However... i still have the remains of my 1700cc disaster which i intent to put back in stock form for another EFE. Long term plans.
Still need to finish my GSX1100ET with a GSX100F engine, sell that one too.
I only have a small shed to work in and do not fancy renting a storage box.
