lol wow sounds great to me ...i didnt here anything in the lower end ....there is a shaft switch you can do to bring fresh never used shafts to the rockers i do this always it always tighten things up ....lots of old oil in exhaust and all that will go away...id keep the running smooth as possible till it gets more clean running lots of setting still to get rid of .... opcorn:

 

[81 Gwing]

i really want that engine for the higher 5th gear

 

[dan filipi]

Sounds good to me but being there probably sounds very different.

I'd adjust the valves and let run good to burn out the oil from the exhaust.

got my taller 5th gear. 83 1100 with 20,000mi motor :yahoo: ..im waiting for a pic of the complete bike that motor come out of.he said it was loaded with chrome and in wicked nice shape

I thought the 82 had a taller 5`th gear, according to the chart not so.

 

[Ansimp]

Something not right there Jeff as the 82 that I rode was 500 rpm slower at 70 mph than the Rats Nest ( 81) :yes:

 

[dan filipi]

My 84 engine that's suppose to have the same gearing as the 83 motor, runs right at 4000 rpm and 70 mph.
These charts are hard to trust, same for the tachometers.

 

[slabghost]

Agreed. Neither the speedometers or tachometers on bikes in general are dependable or accurate. Often they are referred to as clocks. Pretty much any clock running is inaccurate. Broken clocks however are right twice a day.

For my money that sounds right Dan as the 82 was 4500 and the 81 5000 at 70mph if memory serves me correctly and I was lead to believe that the 83 dropped another 500 rpm off due to its taller gearing.

 

[joedrum]

yes the 82 is taller than 80-81 in fourth and fiifth gears in the motor 83 -84 motors geaded exactlly the same ....what dan posted was about right....most charts are full of it...when dan put in 1200 84 motor ....nothing changed but motor size
