JUST CHANGED THE CLUTCH ON MY 2003 UK300 6 SPEED (IN THE DRIVEWAY, STUPID IDEA).
EVER SINCE WHEN IN SAY 3RD OR 4TH LIGHTLY ACCELERATING AT 1700-1900 RPM I GET A VIBRATION / THROBBING FELT THROUGH PEDALS AND NOISE THROUGH DASH. APART FROM THAT CLUTCH DOESNT SLIP AND DRIVES PERFECT ALL OTHER TIME.
ANY IDEAS OR ANYONE ELSE HAD THIS, OIL WAS CHANGED BUT NOT WITH THE BEST STUFF.
THANKS.

surely that has to be something you have simply disturbed from factory assembly?

I would look straight to the down pipe/centre section touching the gearbox crossmember and anywhere else first.
Make syre all cables/pipes are re-attached in any anti vibration clips (etc)

I doubt it any more serious than that.

I had a similar game with my Sti V3. 3''Exhaust j-u-s-t touching the prop shaft centre bearing in shell.

No, don't think so unless it is bolted-up realy badly. I've had mine off about 6 times now and never bother marking things up to the diff flange. Things are all factory balanced separatly.

Look for anything that might as well as it touching something else. When power is on or off the engine twists on the mounts and things can come into contact when they are well clear with everything off.

When I worked in Automotive we always had a simple rule, 'have at least one finger thickness of clearance betwen moving parts'

Things can reach a natural resonating frequency and move alarming distances, yet are quite rigid when at rest.

Look for the simple stuff first!
