Looking for 1200 rocker arm ratio.
And 1000/1100 rocker arm ratio.

Probably not a lot of people that have ever been even curious about that, it is what it is.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

EKvh,
Just set up a dial indicator and read the lift by putting the plunger right on top of the valve retainer and cycle the engine making note of the highest point. That is the lift at the valve. Doing some math you can figure the rocker ratio also. lift at the valve divided by lift at the camshaft. (lifter) would be the rocker arm ratio. As a matter of fact you can get any info you are interested in that way.

@wingandaprayer
Yes, the dimensions needed for figuring ratios. To be useful where I am, I need the info for 1200's and 1000/1100's, which are the same. If you have to disassemble the heads, don't, just measure the actual intake valve opening. I can work backwards to figure the ratio.

@redwing52

As mentioned I am 10,000 miles from my bikes and in a country that has no Goldwing. If I could measure these, I would. My predicament is trying to feed my shade-tree-mechanic side and have a good handle on what to expect when I arrive home in April. My plan is detailed above. It's a one-off attempt.
I am fishing for any info I can get, and beggar I am.

The only thing I have been close to being able to do is using pics from eBay. There the arms look to be a different ratio, but you never know what angle the pics were taken from.

Something like this. It could be anywhere on the vertical line of center as long as both sides were measured from the same spot. Top is a 1000 arm, bottom is a 1200.

back in the 70s that is why we rode em! you could run with almost anything on the road. that DAY IS NOT here any more but back in the day it was MY favorite! but it still 1 of my most memorial bikes. i got a gpz 1100 also. had to have em when they was hot. still have my first of em both. but that day is long gone but not forgotten! so there is not anything but found memories of first bikes. i still like the 1000 gl very much as any bike i have owned. have youu rode a new fast bike.them new bikes are 99% faster through the gears! just think what are are great great great great great great grand kids gonna by riding! 1st gear 200 mph 2 gear300 mph. lol.

life is good.

If we are going outside the box....maybe a small Porsche motor swap?!?


I've often wondered if an air cooled Porsche, beetle or bus motor could work.
