Did a RWYB on RAF Lossiemouth in October and it as 155 tops on the radar gun, although nearly 170 showing on the clock ! Since then I've fitted a pair of Blue Flames and had it Dyno'd at Bob Grant (Knockhill) so once its back from the painters in the Spring I'll be trying it all over again !!
Its funny cos the bobbies wanted to use their gun on the roads on the way home as well, strange eh !!
