i like those adjustable strut tops.

1. Smaller idle jet, even with 45's I idle pig rich, also check that ballance is spot on between carbs.

2. Valve springs, you need more seat pressure.

And I agree the strut tops are awsome! just what I need now!

1)Agree wif u tat too rich...
But 270 cam will coz nosedive rite?

2)Wat kinda valve spring tat i can buy from junkyard?? :P

The strut tops were so rare in Malaysia...
Tats the 1st 1 i saw when i bought it...
Btw i think my engine sound like pings at low-mid rpm even i retard it...
I cant really confirm the sound coz it also sound like those twin...

1. I run a 296deg and its perfectly smooth, only down side is a slight lope under 1200rpm, over 1200 its as smooth as stock with a loverly powerband from 5000-8500

2. GX dual valve springs will help

Im thinking of stock spring from other engine like mayb L16 or etc??
I scare those hard spring will wear off my regrind cam...(not sure bout tat)
Low budget spring i mean...
Thanks...

you'l need heavyer spings to make the best of your cam otherwhise its a bit of a waist. for much over the 6000 rpm mark you will need doubles.. allthough I hav heard of some racers who arent allowed to use doubles useing Haley davidson springs and allso buick V6 springs.

Is single spring good enough or i must use the double 1???
Any other engine's single valve spring(heavier) tat i can use??

Rather go double on any performance 8valve a 16valve head is another story there the valves are about half the weight and you can get away with one spring. On the 8 valve the valves just become to heavy. Anyway that the way I figure it to be.
