Mikeb's Builds Thread

Can definitely relate to that scenario.

Strange how quick logic goes out of the window in a brief moment of panic.

I once changed the engine on my nephews Turbo charged XR2
He didn't tell me that he had fitted one of those fangled gadgets on that keeps the engine running for a while after the ignition has been turned off ( Supposedly to allow the turbo to spool down properly ?? )

After first start, I immediately noticed a major oil leak, quickly turned the ignition off.
Imagine my shock when nothing happened, blind panic when faced with the reality of a newly rebuilt engine likely to go pop ( I jumped in & stalled it on the clutch )

Turned out that I had not fully tightened the turbo's oil feed pipe ( Thankfully, no harm done )

All that aside, it is not uncommon for a manifold to glow a bit when very hot ( very noticeable in poor light conditions )

i wonder how many of us have dropped a spanner over both battery terminals and paniked like mad getting it off. I tell myself not to do it over and over, but the flat top of the battery is such an apealing place to subconciously put tools!

Picked up some Zx6r carbs from ebay for a good price.
They look ok I just hope I haven't been sold some lemons.
So it was time to make a manifold for the CVH. FastDan cut me an inlet flange for the CVH that blanks off the water take off. He also supplied me with a length of 45 OD pipe.

I sat down with my drawing board and worked out the cut angles for the pipes to give me a 20deg incline on the carbs, I'm sure I read its not necessary to get the float chamber line horizontal so 20 deg is halfway so should be good.

Using the trusty rage saw to cut the compound angles made things easier, it was still tricky getting everything the right length after compounds cuts.

heres the result

I'm actually quite impressed with my skills!
The inlet looks good all painted, I've gone for a red highlight theme, so will be using red coolant hoses etc so should look nice and will go well with the white and black body work I have planned.

Just need a fuel pump and som 8mm hose to try out the bad boys!
No idea what hp whe will put out over the standard, hoping for about 115bhp.

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
