CHP Oil passage tube. Installs in your stock TRX90 clutch cover and engages
in the primary drive gear nut, to supply oil to your crankshaft.
Machined out of billet aluminum for a precise PRESS fit.
Press fits into stock TRX90 clutch cover.
After you have completed your big bore motor and have installed a 54mm
stroke crank shaft, this billet tube is required to bridge the gap between
your clutch cover and the stroker crank shaft.
Without this tube, you cut off oiling to your crankshaft
