Hello there!! I believe you have the same trouble me and another owner in Lisbon are experiencing! I own a 2014 M3W and since 1,5 years from now starting the engine was becoming harder and harder untill it just didnt start without a push. Iddle was normal and running particularly high rpms above 2k was absolutely fine! Then I left at a certified garage in Lisbon where they had already another 3wheeler with misfire - they identified fault at hydraulic tappets! Currently cars are stopped more than 7 months ago since original S&S X-Wedge Hydraulic Tappets (part number 37-0030) seems to have been discontunued from S&S and european stocks like zodiac dont have them!! I am looking for these and probably more morgans might stop since these seem to fail with time, anyone might know or have stock for these?

My 3wheeler engine serial number P5600503

Best and luck with yours!!
