I currently own a SG and today decided that my SG needed a baby brother. So I purchased an X90 shortster. I had one of these as a kid and it is what I learned to ride on. I pick the X90 up on saturday!

nice starter for the kids.

 

Nice buy, I have 4 X-90s, 2 with titles(street legal) and 2 without. They are a blast to ride around town and easy to park. If you need some sources for parts. let me know. The best that I have found is Jim's Harley in Mendon, Ohio.

Those are so cool. Unfortunately for me, by the time they came out with the Shortster, I had already graduated up to slightly bigger bikes. By the tank graphics, it appears to be a 1974 model. They changed the graphics yearly and I had a 1974 SX175 with those graphics on it.

 

I just recently picked up a X-90,a trade for some work;and know absolutely nothing about it. I have a few questions about it that I'm hopeing I might be able to get some answers here( haven't had much luck anywhere else )

1)dose anyone know where I could get a shop manual

2)the fuel system :
A)fuel oil mixture is it a premix (rider needs to do the missing ) or a self feed system.
B) type oil and grade or wieght.
C) if it's premix, the ratio.

3) the gear case :
A) fluid or oil.
B) wieght or type.
C) capacity

4) clutch :
A)is the clutch houseing part of the gear case, in that dose it use the same lubricant; if not:
B) tpye oil or fluid.
C) wieght or type
D) capacity

 

1. Shop manual or parts book - ebay.

2. You can use any good motorcycle 2-stroke oil in the injector tank or premix at 50 to 1. Originally Harley wanted the oil mixed at 25 to 1 in the 1970s but with todays modern oil I mix at 50 to 1.

3. The manual calls for 2-stroke oil in the gearbox but I use SAE30 motor oil in the gearbox. It takes 1.3 pints.

 

Love those Shortsters! Great fun!

 

Where was it manufactured.. I heard once Italy?????

 

The little bikes were made in Italy at Aermacchi, an Italian motorcycle company that was owned by Harley Davidson.

 

Kool. I thought maybe. I have an NOS 1971 Viking never riden sitting in my rec room. Someone saw it and said that Harley Shorster was made by the same company and they do look very much alike.
