Finally had chance to take mine for a spin unfortunately only in to the town but hay it's better than now't and quite windy 

 , first impressions are as follows:
Start's better and ticks over virtually from go 

Definitely smoother 

Picks up far better from lower revs 

Sounds awesome on song with my can 

I must admit I was a little 

 about getting it done  but on first impressions, am I glad I did............................ 
Oh Yes!big thanks to Mike 

 for doing the fitting and obviously to Ivan for developing these kits, Can't wait to try her out on a longer run.
