Working up the BHP ladder.

Just installed my ultra light flywheel set up with a new plate. The flywheel and backplate have been machined because the drive faces were chewed up from a paddle clutch. The faces have been flattened in a lathe and the turrets on the backplate macnined accordingly.
I am using an organic AP race/rally plate (new).

There is a horrendous amount of clutch judder! Is this normal and does it just need some bedding in or should i be worried?

Ta very much

Lowestoft, Suffolk.

I had a panic when I fitted mine a month or so ago was doing the same, A few miles on mine has now cured it, also slipped it a few times while on boost when stationary.

Try doing a few standing hard starts with the clutch really slipping it.

I find that after say Avon park, my clutch feels lovely as it's all smoothed of and beded in.

Thankyou Avonbar!!!!!!

leeds/wakefield.

really bad judder would suggest poor machining , in so much that the plate is no taking up evenly,, are the three bolts all tight,if ones loose it will judder.

and no clamping load backs up my theory about machining,
i suggest someones made a cockup.

who machined it and do they know what they are doing,

Ian at Avonbar machined it and considering the whole thing came from there in the first place in absolutely screwing!!!
The second hand unit with all the machining has now cost me more than a new setup!!!
Just ordered a new shinny one from minispares.
