Hi all, I got 2 brand new NOS 1UA cylinders and it would be a shame to fit some over worn YPVS valves in it. Since YAMAHA new parts are expensive (and not impressive about quality/finish) I’m considering billet versions. I remember TSS in Australia selling 31K version and 1UA version to fit better 1UA cylinders. Now Mad Bikers Design is selling Wicked motorsport billet valve: www.mb-designs.co.uk/page12.php?view=productPage&product=220&category=9 and Norbo is selling some too So questions : are the wicked version the same than TSS ? Norbo: where yours comes from and do you have 31K or 1UA version ? What is better on the &1UA version ? Thank you Xavier |

Thank you Xavier I believe(hopfully someone will correct me if im wrong) there is about 1mm difference between the two, due to the exhaust ports being slightly different, the original ones from Yamaha had the same part number for both 31k and 1ua as you have a 1ua i would go for them.. |

Dunno.. I got TSS billets. First batch. A year for the Twit to actually deliver the paid for items.
There was a choice 1ua Or 31k I wanted the Iua What I got was Wrong .
There was a helluvalot of port fit errors in MY Iua cyls.
The port matching In and Out..was .More like 3 ~ 4 MM both sides of the valve.
IMO They were simply machined wrong... no other plausible explanation.
Lotsa horeshit and overselling with TSS.
Hopefully current supply Fits.. as claimed?

I have TSS's 31ks and they fitted fine. I dont think TSS made (if had made) these, Legend and FTTP and others have sold these long after TSS was gone.
