i have an 87 carb boot, and yes it is shorter. but the bend is all wrong. it puts the carb into the shock even more. i had read this before and thats why i went ahead and bought a newer style intake boot. im just waiting for my 98 aircleaner boot to show up and then i will see what to do. if a hadent of spent all this money on a port job, i would throw this cylinder into the corner and put a newer one on!Roostius_Maximus wrote:the 85-88 jugs have a long casting and a short boot, the 89+ have a short casting and a long boot, resulting in the carb spacing from the piston being the same.
A long boot on a long cylinder makes a mess of trying to fit it in an AF, an 87-88 boot has the correct angle to work, and the length gets you back away from the spring. The front left fuel bowl screw will almost contact the lower left boot bolt normally, however far back you are from that is what you've lost for room on the filter side

if everything seems to be under control, ur not going fast enuf!
