The JTEC showed up yesterday and......... ITFITS !! Like a glove. Trimming the cowl today but it fits completely within the cowl with about an 1/8th inch of clearance. Some foil heat tape on the inside just for good measure and I am good to go. Just need to drill and tap the muffler for my oil port. A BIG THANKYOU ! to Al at JTEC for his help and amazingly fast shipping! I'll post a few pictures when it's mounted up.
