At 10mm over using 1098 cylinders is efectivly a short stroke 1098, similar to the many 749/924 kits we sold should be good for an average of 20HP thruout the rev range.
More fuel is needed so will need a Microtec, Nemesis, Rapid Bike or Powercommander. The first in house job will have a Microtec and full Leo pipe so will have a map from it.
Normaly takes them 30 days so not sure on delivery date with the holidays, have 3 sets pre-sold. Should be a kit price around $1800 for pistons, rings, pins, clips, new cylinders and oem 1098 head gaskets.
