First of all, just like to say hi to everybody as i am new to this forum. Really great forum with loads of tech stuff and very clever people. Thanks to Saltygpr(Paul) for pointing me in the right direction, top bloke and very helpfull.
Anyway Last time i took my 04 gp1300r out my mate on my old xlt1200 ran the same sort of speeds infact some times he was quicker holeshot and top speed. The started to worry me a bit. So i ordered loads or Riva bits to see if i could improve speed. Put a solas 13/19 impeller on, riva ride plate, pump seal kit, riva scoop grate and some trim tabs just for starters. (got a modded head, protec stuffers d plate efi controller etc to go on but not had time yet to fit it.). Went out on Sat noticed the ski did not start very well at all and seems to be no quicker . Got really gutted when 2 kids on a rxt smoked me. some people have suggested the cat is gone, the ski has done 70 hours). Is it the best bet to fit the d plate and see what happens.

any info would be gratefully recieved

many thanks
