SINGLE CYLINDER STAINLESS STEEL PUSHROD TUNNELS, DIY

SINGLE CYLINDER STAINLESS STEEL PUSHROD TUNNELS, DIY

SUITABLE FOR 350, 500 AND 600 SINGLES WITH THE FULL LENGTH TUNNEL (NOT THE VERY EARLY BIKES WITH THE GLAND NUT ON THE BOTTOM AND NOT THE LATER ONES WITH THE SHORT REDUCED END TUNNELS THAT DISAPPEAR INTO THE CYLINDER HEAD).

CONTENTS
2X LENGTHS OF STAINLESS TUBE, SAWN OVERLENGTH.  YOU WILL NEED TO SHORTEN AND DEBUR THESE TO SUIT YOUR ENGINE.
4X PUSHROD TUNNEL END FINISHERS, TURNED TO SUIT THE TUBES SO THAT THE TUBE NEATLY ENTERS THE FINISHER WITH A NICE SNUG FIT.
2X RUBBER O RINGS FOR THE BOTTOM WHICH SEEM TO SEAL WELL

THE TOP WE LEAVE TO THE CUSTOMER, FIBRE WASHERS ARE OFTEN USED.

NOTES:
THE END FINISHER MAY NEED TO HAVE A LITTLE TURNED OFF THE VERY END, SUCH THAT THE REBATE SUITS THE SEALING METHOD CHOSEN.  WHEN YOU ARE HAPPY WITH YOUR SEALING METHOD YOU WILL NEED TO SHORTEN THE TUBES TO SUIT YOUR APPLICATION.  A LATHE WOULD BE USEFUL BUT A HACKSAW AND A FILE WOULD SUFFICE.  ONCE CORRECT LENGTHS ARE ESTABLISHED USING SOME ARALDITE (PART NUMBER 610594), GLUE THE ENDS TO THE TUBE, KEEP COMPRESSED UNTIL THE GLUE HARDENS TO AVOID CREEP.  WHEN FULLY SET THESE CAN BE POLISHED AND IF DONE CORRECTLY THEY LOOK IMPRESSIVE AS IF THEY ARE ONE PIECE
