with wrist-pin roller bearings and because the rings haven't properly seated, your motor is really 'tight' at this early stage.
by the time your at the end of 3rd/into 4th tank, you should be all broken-in and well.
Sounds about right to me....I've been to 27MPH with the stock 44T and the engine is buzzing pretty good....To go faster after breaking the motor in go with a smaller rear sprocket....lower cruise RPM and higher top end..
thanks for the info This kit has been so good I was just second guessing my self. I was thinking that something got to give but so far all is 100% . Andrew Im building the black kat bobber and would like to ride low and slow 70cc what sprocket would work best ?
NID_FTL ThatsDax.com 2 weeks to ship but worth every day of the wait.I have had no probs. with the kit at all not 10hr's to install fired right up has not let me down .Do your home work on this forum as I did you will learn a lot . The kit has no directions to install and it was my first build went fine. Andrew Looking to run 10/15 MPH want the bike to be smooth not jerky 26" rear. Thanks Adam.
