idea for improving oil feed to the cams |

Good morning gents, |
|
I am rebuilding my Nuovo Falcone engine. It started with |
|
intending to just change the clutch plates but once the cases |
|
were off it was clear that more work was needed. So far: |
|
Crank regrind including recovered nose for the oil feed, and |
|
new big end. New bearings throughout the engine/gearbox. New |
|
selector forks. Complete cyl head re build with improved |
|
valves/new guides/springs. New standard oil pump. Camshaft re |
|
grind/new followers. |
|
I'm intending to fit a viton oil seal instead of a plain |
|
bearing on the crank nose oil feed. My attention is now on the |
|
camshaft oil feed. What a dumb system that relief valve fed weir |
|
is!! I'm thinking to tap the relief valve piston and fit a 0.3mm |
|
carb jet into it, giving a permanent small feed to the weir but |
|
still having a full valve operation at 3.8 bar. |
|
Has anyone done this? and/or any thoughts? |
|
PS: I already have the Moto Pirner modified oil feed and full |
|
flow filter system fitted. |

There's a 'standard' fix for this adding a separate oil delivery |
|
pipe, but I don't have full details of it. |
|
I think it originated in Germany, so you might find something on |
|
guzzitreff. |
|
Also pretty sure it's covered in Leafman's thread on advrider, |
|
but I can't get into that right now to get you a link. |
|
Kater on that thread has definitely done that mod. |

I have the secondary valve feed. It smokes after a while on |
|
idle. Apparently they all do... To minimise cam wear I don't set |
|
the idle really low. I have it set like a brit single. |

This is the additional feed to the camshaft Cloggy: not to inlet |
|
valve |
|
Incidentally, I have the inlet oil feed, and no issues with |
|
smoking, but I also have the cylinder head modification using |
|
8mm stems and guides fitted with valve stem oil seals |
