I have just purchased a 1984 wideglide .But i am not sure whether the engine number is a Harley number.(engine number and vin number do not match) so i am unsure whether the engine is a genuine Harley motor. Not all that concerned about it as i picked the bike up cheap and it runs well.

After more investagations i am starting to think this is a buell engine. 

The EB in front of the number was a dead giveaway!

From memory Evo engines had an abbreviated VIN as their Engine numbers. 

My guess is that motor came from a 1990 FXRS, 1340 CC.

Yep, Thats what I worked out as well.

Hi all...here's my little input on your research SnakeMan,I believe you have got one of the the first FXRS 80cubes evo engine(the first 2 letters..EB stands for" FXRS" model),although it's 1984 in papers it might have been factory built in late 1984 for the 1985 season.1984 was the last year for the Shovelhead engine and were no more produced as a powerplant by HD afterwards.I'm not 100% sure but the "LL" following might indicate the "L" for 80 cubes" and the other "L"for Asia pacific import....then the production number.
