    Parts bike is an 81H......4N9 is an 81.

    The 72 is a combination of 72 and 81SH.

    880 kits require oversized sleeves that require the barrels to be bored to take the oversized sleeves and the cases have to be bored as well

    .........Money spent on a head from Craig weeks http://www.650performance.com/Home_Page.html and a 750 kit with well tuned carbs will get you to 120mph.........There was a guy who used to be on here a lot used to have Helco 840 engines but he found they had to be rebuilt every couple of years.... xs1961 http://650rider.com/index.php?name=coppermine&file=thumbnails .....the 750 kits keeping the HP to around 70 or just below will last years without having to rebuild...........

    This may be of interest to you, only a 750, still good for 120mph.... http://www.xs650.org.au/Club Racer Stuff/Club Racer.htm .....Later years from about 2013 the pages read from bottom to top...........

    Well you sure do have a good project and a bunch of spares too. It is pretty neat to see the guys here go thru and see what part is to what year. I always like seeing the bits that have gone on each new bike that shows up on this site. Good luck with the build!

    I gotta say this site and the members are awesome, I can't tell y'all how much I appreciate all of the help! you guys are amazing.

    I'll be ordering the main harness from MikesXS, I feel like for $60 its well worth it instead of me and my dad trying to make one from scratch like we had been considering

    Have some reservations about the motor in the 72 frame......spidery sense twitching..........

    Your engine side case has gear No's stamped into the side cover...........Yes later engine side-covers did interchange with the 72.........Why i have reservations relates to the paragraph about the side cover differences

    Early motors from 70-73 didn't have the gears no's stamped onto the engine side cover......that started in 74.........All pics are off different bikes

    72, Brochure and pics

    74, Brochure and pics....Can see the gear no's stamped on the side case

    Around the year 75 the engine Cases and side-covers had a modification and where the chain-guard front sprocket area was covers the cases and engine side-cover changed from a square edge to a round edge.

    Comprehensive threads about this........Second thread goes into this as well with some updated info

    Pics show where the side case meets the cases and the fit..........
    72................................................73..............................................74

    In your pic it looks like the engine side case fits the engine cases........Bit hard to see so its worth a look so, check the engine case where the edge of the side case meets the cases........if your engine cases are round like the engine side case then it may be a later one...... No's can be changed.........This is critical when or if ordering engine parts.........

    A couple of links regarding early frames/Motors and the interchangeability of the motors/Frames for later yaers and differences
