Is that parkitt as in park it in a laybay and forget becuase its not operated correctly? I have numerous bikes on three different dynos and each run on each dyno was within 0.5bhp of the other two. The parkit thing does seem a bit amateur............No RPM reading even at anglesey...........

One of the first DD bikes on it was my 600 Monster Class B bike as ridden by the journo at Brands Test day.
This bikes tacho wasn't accurate, several other bikes that were among the first to use the Dyno had no Tachos what so ever and as the Dynos Ignition pick up system was off for repair, the start of the DD database was a bit offset as the 3000 rpm calibration point was guessed at.
Over time as more and more readings were taken with more accuracy the offset was gradually corrected and readings became more accurate, with the figures trending downwards.
The Dyno operators also had a few initial issues getting the conversion between DIN and SAE sorted
The reading of my Class A bike at Pembrey was only tenths of a bhp lower than that given on the DWR Dyno at 61.3 bhp which is about what I expect from mainly home brew setup. Could probably eek a bit more out on the dyno if I add another Lambda port and get both cylinders mapped individually |
