battlax,s and big smiles

Dug the red 400D out of the shed this week, replaced manky 110/90/18 metzler and 90/90/18 pirelli phantom with a pair of old stock Battlax BT35,s 110/80/18 and 90/90/18. put some fuel in and took it for a first spin of the year, tyres have transformed what felt like a lumbering oil tanker compared to the 250 on K82,s into a much nimbler bike. cannot thrash it too hard as it only has 160 miles on clock since crank rebuild,

but when i opened it up abit it kept dying, ok poodling along but get over 5000 revs for any length of time and down it went, nursed it home, could hear a hissing coming from filler cap, remove cap clear crap from vent, another test ride and well its pretty good now. only thing is it surges on the overun
