Morini engine, Stretch frame, Nexus 8speed hub

This is a work in progress. I will post more about it later with more pictures.

07/23/09 The engine is a 49.8CC 3.2HP and it is upgradable to 5.8HP. I only have about 30 miles on it and most of them test runs. It seems as strong or stronger than my HT engine. My speedometer read 44mph when i opened it up recently. This is the same as the HT engine but the Morini isn't broken in yet. The Morini has some vibration at midrange but smooth at high rpm. Some of it may be the clutch and I hope it gets better. It is barely audible when idling compared to the HT. The pipe I have is loud (for me) but I'm working on it. I included a picture of my rear motor mount/jackshaft combination. It also holds the idler for the jackshaft to crank chain.

The rear hub is a Shimano Nexus 8 speed with a roller brake added. The hub is rated for offroad use and has about 400 motorbike miles on it with no problems.

wow, that is awesome. EXCELLENT clean workmanship.

i was running 5 HP thru a front freewheel for awhile, i fear that will be you biggest maintainance issue.

otherwise i hope you kept your layouts and dimentions, i can see requests coming your way.

It is a Greenline. Bought it off eBay $199.00 shipped. Best ride I've owned and holding up so far.
 
Super nice !
Do you have a link to where you got engine.
Found some.com but can't get them to open.
Really a fine ride. Good job..
 
Very nice, professional job, no complications, clean appearance. Congrats on a job well done is that the 3hp or the 5.8hp? How long did it take you to complete, how much heavier is that engine than the standard china engine? Good Luck with it.
