More water cooled engines

Old Bike Australasia - - LETTERS TO THE EDITOR -

When I did the ar­ti­cle in the last is­sue about the water cooled Tri­umphs I thought that it was ap­pro­pri­ate to do so be­cause they were unique and un­usual. Not so. I have been con­tacted by Gra­ham Branch, a mo­tor­cy­cle and car en­thu­si­ast from Port Mac­quarie who is the owner of the late Mau­rie Pear­son’s sin­gle seater hill climb type car fit­ted with a Manx Nor­ton en­gine. He ad­vises that in 1990 he pur­chased two Tri­umph engines – a 1949 Tiger 100 and a Speed Twin. Both of these had water cooled jack­ets around the cylin­der bar­rels. He later re­moved the head and found that the in­ter­nals were new and they had not been run at all since they had been re­built with new parts. He tried run­ning these with a ra­di­a­tor and fit­ted a water pump as well be­fore he gave up and fit­ted reg­u­lar bar­rels. Whilst later at­tempt­ing to ac­quire an en­gine for a fi­bre­glass Berkley car, he also pur­chased in that deal a 328cc two stroke Ex­cel­sior which had also been fit­ted with jack­ets for water cooling.
