'83 GL1100A cam upgrade

Postby NKYWinger » Wed Jul 04, 2012 5:05 pm



It has been mentioned on one of the other forums, that I can get some additional HP out of the old gal if I install 85-87 cams. So.....three questions -
1)Where can I find Gold Wing cam spec? (lift/duration/overlap)
2) Is this a reasonable approach to adding some HP?
3) If #2 is a no-go, then what would be?

Thanks in advance!

I don't alter engine designs.Generally speaking you'll never notice a increase of 10% in HP,only the 10% loss of a few paychecks.
Tell ya true....I tweaked my 83,fixed all the malfunctioning parts and it would flat outrun my 1200 any day.
When a bike is running around 90hp,changing it to a 95hp is mute.
If your gonna change...move to a 1500.
Wait...ya know something....it's not better or worse...it's just different.You know hp/weight ratio stuff.
Ya really want to be surprised?...bob the bike...loose 200 lbs of stuff...leave 2wheels,handlebars,seat and that engine.
I've have/had all 4 models.I really don't have a favorite.....well..except the 78 gl1000 naked.
It was just nasty radical.

I've not heard that fitting 1200 cams will improve it, but fitting 75-77 cams, left hand head, carbs, manifolds, advance/retard, remarking the crank timing mark and Dyna ignition system will get you more power. A lot of work, time and money for a result that you may feel but only if you are a push-on kind of rider, otherwise as Virgilmobile says, with the extra weight of the bags, fairing etc. you are chasing dreams. Plus your fuel consumption will suffer.
These are NOT sports bikes, plus unless you are rebuilding the engine, pulling extra power out of an old one and using it will quickly ruin it.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!

OK - I guess it really isn't worth it... I'll just have to enjoy my 30 year bike as it is...only 40K miles and looks like new. Quit yer whinin' John and just ride :=}

From a guy borne and raised in Portville NY.....
Ya want some cheese with that ..
Really,it is what it is.Just get new timing belts in it,fix the 3 yellow wires,sync the carbs and don't let it set up too long.

I know about the winters......I used to put in screws in my dirt bike tires for traction for the winter riding. :o
