Well here it is finally.
The first start vid!

Its actually its second start, but first start with the new manifold and bike carbs.

It needed a lot of choke on the carbs but seemed to run nicely, a lot better than the old carb and the exhaust manifold didn't glow bright red this time!

First mod to the carbs will be adjusting the idle mixture to get it running without lots of choke, then not sure what to do for IVA. Leave it or open up the jets to 1.5mm or 1.6mm.

I've also laid my loom in place and will be connecting up the ignition , so it will start off the key next time (super cool!)

Mine passed iva on the standard jets with flying colours, obviously you cant drive it hard up in the revs like that as it will be lean

After a good few runs on a rolling road I ended up with 180 jets, 170/175s were safe too mixture wise but 180s had a touch more power

Still would have passed emmisions tests if required with the bigger jets in

The cvh head doesnt flow very well so doesnt suck very well hence the quite large jets for a modest power output

Well done Mike, looks a tidy build so far you should be proud

Congrats on the first ( 2nd in vid ) start up, sounds great
A major milestone of anyones build,

cheers

Yeh the builds really starting to come together now.

Mark, did you do anything to the carbs to get the engine idling as mine needs lots of choke at the minute, i was planning on just adjusting the idle mixture on each carb.

Mine ran pretty well as they came off the bike

If you havnt already make sure the idle screws under the carbs are all in the same position by screwing them all home then back out the same ammount (approx 3 turns should be somewhere near)

Running without a silencer/no airfilter and no coolant isnt going to give you a steady idle with no choke after 30seconds running

I suspect once you have coolant in and can let it run for a while with the throttle stop adjusted accordingly it will idle anyway

When you get around to fitting an air filter i would change two of your trumpets also so they are all the same length

Something else to consider with the zx6r carbs is the heating circuit underneath with the little coolant pipes

Every man and his dog will tell you, you dont need to use them but i would suggest you do! My carbs froze up in temps nowhere near freezing point (due to fuel atomisation having a refrigerant effect)

I know the same happened to Spuds car with these carbs too

I have them plumbed in and its never happened since

So unless you are using it only during summer months i would plumb them in, but you do get some nice dry sunny crisp winter days where you cant help but take it for a spin

Small bit of progress.
I bought a susuki tl1000 LH silencer off ebay for £10. made up a link pipe.
Looks ok, its mainly to keep the neighbours happy, sound pretty good to.
May have to upgrade for IVA but fine for now. Will post a pic when I get her outside next.

So £10 for an exhaust not bad!
