Ninja JX.21 BOA / Fresh Rebuild
I have a Ninja JX.21 BOA for sale. I just got this motor back from Rex Welch @ RW Mods last week. I sent it to him after just 2.5 gallons just to be sure it was up to par and ready for an upcoming big race. After his inspection he replaced both front and rear bearings and put a slight pinch on it to increase compression. I have decided that I don't need it afterall and would like to sell it. It has been partially broke in using using the heat method per Rex's instructions but only two tanks so it could use one or two more at half RPM's or so. I can get pics upon request. Engine is in great shape and very clean.
$150 shipped (Paypal gift or add 3.5% for fees)
