New guy needing some info.
4stroker:
we are at sea level.
i will tell him about the 44 lectron.
k5abuser:
stewart knows more about alky than a wine-o . but i know that stewarts motor hold up to all we can dish out and that the dyno numbers are right on . i have a quadzilla that at one time made 100 hp at the chank (7 flat in the 1/8 97 mph taking off in 5th) when i rode stewarts bike i told him it felt like my quad on 120 otane and nitro mix. it dyno'd right at 100 hp at chrank . he has seen close to 105 . everyone that rides it comes back and says thats enough. resleving the motor with a steel sleve is the wrong move the k5 motors were not designed to run a steel sleve . the 560 was steel sleved and the piston sezed.i hope the 91x91 works would love to see it . others have tried to bore bigger 60 over (with out stroke to match ) makes the most hp but you lose the reliabilty. wolbrinkrace took a stock motor we built to bonnelville salt flats and set the modified record at 132.4 mph with a stock motor on 110 octane. 2miles up to speed with the third mile a flying timed mile wide open .run after run on the same motor and piston . they are riding it on the dirt now and playing . that motor pulled 110 mph with my 290 lb butt on it in full mx trim before we sent it to wol brink.

kaw rider:
if you what to make more power then you will have to make a oversquare motor or fix the many things that this motor has wrong.
4stroker:
