not really ... your 79-78 1000 has the mildest cams....second largest carbs ....if all is doing good they can run well ,,, as far as 1000s go the 78-79 have the best lower end ...75-77 have the most aggressive cams and the largest carbs ...the 75-77 lower ends on them are a bit noisey from the primary chain slap when they run rough ....the 1100 motor is and improvement over the 78-79 lower end ...crank is beefyer and primary chain tensioner is even better ... there carbs ar smaller than the 78-79...but at least they finally address the cv carbs lack of getting going with excellerator pump added...the cam a bit hotter than the 78-79 also ...carbs seem to give up at about 7000 rpm and fade off ....many gearing changes in 1100 motors 80-81 were the lowest geared of all oldwings and in 83 the 1100 was the tallest ever made at that time ...1200s have the best lower end ...its basiclly a stroked 1100 with beefyer crank 11% more oil and coolant flow ...and best gearing spread of all the oldwings along with the 83 1100...thing i dont like on 1200 is carbs are the smallest of all oldwings ... heads have small intake valves ...head is a hydro lash adjuster...not simple to deal with ..i like the big valve heads of 1000s and 1100s ...i like the early aggressive cams of the 75-77 1000s... i dont like any of the stock CV carb racks ....
my bike is a 77 framed 1000 with 86 1200 motor with 1100 heads ...76 early 1000s cams ...1200 piston knotch so piston dont hit...with a progressive linkage weber 2 barrel carb ...that makes a complete never said slow oldwing .....it is a rocket hunter ... the bike also the best.. fantastic multi spark c5 ignition also ... it will jerk your arms off the bars ....but also did a several month road trip with no problems ..this is all just my opinion ..what else can i say and be honest ...this ought to fill you up with my thoughts :heat:
