Sunday Fun Run


Here's a short film I made about our fun run adventure driving the Fairlady roadster:

Carburetor and Engine Tuning by Race Guru Fil Gulfin

Finally, Fil had an open schedule today for tuning the Fairlady. New jet settings: Pilot Jet - 52.5, Main Air Jet - 170. Hopefully, fuel consumption will also improve.

Cleaned and checked all the Mikuni PHH40 parts and assemblies. Found a number of blocked jets and leaking parts. The pilot screws have been replaced with the correct Mikuni screws. The previous screws were from a Weber carburetor!

The butterfly valves were still in good condition and are sealing well. The grooves on the rubber isolators have been sealed shut instead of just using rubber tubing as what the previous shop did during the last overhaul.

The timing was also adjusted since it was retarded. The timing advance mechanism was also checked. Valve clearance was also tweaked.

New NGK BP6ES spark plugs have also been installed. The idle is so much smoother and the throttle response is insane! There's more power in the engine and low end torque also improved. Top end power has greatly increased and also much smoother. The induction noise and exhaust tone is so much more addictive!

Resto-Mod & Restoration Updates:

Fairlady @ Caltex

1. Re-jetting of Mikuni PHH40 twin side carburetors and engine tuning by Fil Gulfin - still waiting for Fil's call
   
2. Ordered a set of HD Kai semi-race front disc brake pads (0-500 degrees Celsius) from Japan c/o Speedmode - P7,000 for the set
   
3. Greased zerks at Caltex
4. Planning on buying Sparco 4-point racing harness - found a supplier that is selling it for only P2,700 each
5. Planning on re-grinding the disc rotors and flushing the brake fluid prior to installing the new set of racing brake pads...when I get it hopefully in 2-3 weeks time.
6. Had an oil change using Valvoline's 10w40 DuraBlend (Synthetic Blend) oil
   
7. Had recently cleaned and sanded both rear drum brakes and pads
