Project My Fizzer

So the old bitch stayed true to form and wouldnt run .... it did fire many times though after a six pack of starting fluid
Aerostart worked so much better than Start Ya Bastard
Might resort to 91 straight down the carb throats

The fuel pump was leaking so Im hoping its just died and not feeding the carbs .... its the original and I had replaced it with a cheap china but from memory it failed .... time to search the 101 boxes of FZR parts

 

Emptied the bowls as its been sitting for awhile .... fuel was ordinary
Fresh fuel and it started (with help) and ran .... wouldnt go above 7/8000 RPM and was smoking from the headers and also out the EXUP cover ... Im guessing I didnt install the valve correctly and thought I should be checking the orientation at the time ... Id say its locked shut

The smoke alarm went off in the lounge room and the neigbours Im sure enjoyed the screaming open exhaust on a peaceful Sunday arvo .....

 

Workshop is in the back "sunroom" .... I can be a lounge lizard and contemplate my latest design and engineering breakthrough .... or just throw empty stubbies at bikes that wont go, without getting up

I think I have the EXUP correct .... been awhile for me too .... theres really only 1 way it will sit.
Its actually nearly fully closed at startup .... these are different headers that had a visit to the metal drop saw and obviously painted .... so thats probably more the cause of the smoking

Sensitive to engine speed, the EXUP valve is almost entirely closed at low rpm and gradually opens to permit unrestricted gas flow at high rpm. Improvements include smoother and quieter idle, more power at all rpms, significant low-range and mid-range torque increases, and higher gas mileage. By gradually opening the valve as revs increase, the positive wave in the mid-range is eliminated, yet the exhaust system can "breathe" fully at high revs for maximum power.

Its the first attempt at running with the COPS installed so Im hoping theres not a glitch there .... it seemed to run smooth enough but just RPM limited
Need to remove a little engine oil too as I overfilled it slightly

Ill try again tomorrow

 

Smoke? what smoke ?

 

So redid the EXUP .... theres really only 1 way it will go

Changed the fuel pump as the original sounded dead

The vid shows it running , holding it on full throttle

Strange behaviour
So ... fuel or electrics
Yes the carbs have sat for some time but the new harness and COPS are untested till now.

Temps on all 4 headers were somewhat the same
And **** it was loud ... I had to get the earmuffs

 

Slides were sliding just fine

Surgery table enabled

First problems .... choke plunger hanging out and brass pipe has come adrift again

Ive only opened #1 so far and a bit gummy in the bowl
Main jet clear
Starter and pilot jet blocked

Ho hum
Looks like Ill have to forego church tomorrow and operate on Mikunis all day





Other than that I loaded up a 15T sprocket (17T stock) and lubed and tightened the chain for those wheel standing takeoffs

 

Yep fixed it initially back in the day

 

#2 carby

All jets blocked and the jet holder bolt/screw broken

Mr Green/Blue .... your o rings are holding up well .... its nearly 10 years since I initially did these carbs
I also actually found those sleeved jet holders ..... so in they go finally
The merge chamber o ring on #2 has a nick out of it .... are any others in the kits the same? ... I have plenty of your o rings on hand , but from pre merge chamber discovery

Tip for young players .... dont have the pilot merge chamber bung sitting on the table after u have put a carb all back together
