what power should i expect with modded 1409 cc

managed to get to dyno in freezing temperature

only managed 1 run - why fuel pump was not supplying enough fuel

210.5 hp with 14:1 AFR , IT was 210 with AFR 13% back in July
2nd run AFR was 15% and 207hp , last run was 192hp with 16% AFR :eek:

But the power and torque was up before fueling became lean

below graph shows today (OEM stacks, new plugs, new Sprint Filter and injectors cleaned) versus run in July this year

torque up from 121 to 125 lbft and 5 more hp across low end and mid range another 7hp @7,000

expecting more top end , new fuel pump ordered , so should be back at dyno this week or next :cool:

Put a HI FLOW paper filter in and you will see better low and midrange power without any loses at the top.
I have test both filters(sprint and hi flow) in my 1441 and i prefer the hi flow....
 
Returned to dyno we took out the old and added afternarket

with decent pump we needed to knock off 6% fuelling top end and mid range

really please to get 214 rwhp and 127.6 lbft - that torque figure makes the difference mid range
had to take it easy as still -1 C coming home unable to give her full beans
plus i picked up a slow puncture

i have only used this dyno in the 14 years i have owned the bike and Dynostar dynos are pretty accurate
