Hi all i have arappy 660 & fitted a looney, I went night riding the problem is when i stopped i looked dow at the header pipes and they were glowing red should this happen? after a min it did cool down
Also i am running 145 left/150 right and 3rd clip no the needles, the bike runs ok throuought the rev range i have been issued with two 160 jets and two needles which are longer and thinner than stock items please asdvise!!!!!!!!

I was told today that i should fit the two 160jets in leave standard needles and adjust air screws 3 turns out i done this and runs perfect and the power gain is wonderfull oh i also cut out the flange bit in the snorkle what a different bike
