Under seat mods.
As Dazco says, you remove the seal. I then cut away a lot of the plastic under part of the seat with a Dremel. it looks very neat, not a hack job.
This was being done whilst dynoed.The seal was worth about 2hp and the mods another 2-3 from memory.
Overall I am getting about 105 hp and 167 nm of torque(126 ft lbs).
I currently am getting my original 1600 cams re profiled and will be experimenting with pod air filters as they guys doing the work think we will get around the 120 hp mark. Will keep you posted when it is done.
