Ive had a few. They are all restricted still even though they have the ypvs servo the only full power ones are late 80,s early 90,s from Italy, the Swiss and German ones ive had were easy to derestrict never had a French one, I always laugh when I see them on ebay as "full power" the last Swiss one I had was an 88 and it had more restrictions in the exhaust I cut it open in so many places I ended up throwing it in the bin, the ypvs cables were slackened off so the servo had no movement. It was all easy to sort out though new exhaust and 2 mins setting the ypvs cables up.
I've seen a few on ebay over the years and just wondered if they were a possibility .you always see 250/350 lc's on german plates .but what I'm thinking of doing is changing the fuel tap on my gsx and then selling or swopping for a dt still not sure which model though.
