GOOD "OLD"READ brought forward (Motorcyclist mag. Aug.1981)

[Piute]

The most effective (easiest and cheapest) way to raise the 750's performance is to increase its displacement and to improve breathing. The maximum displacement one can get with a simple bore job is 836cc. This is 110cc more than stock and, if the breathing is improved, will just about deliver the maximum reliable horsepower (about 75) of the otherwise unmodified engine. We used one of the Action Fours 836cc cast piston kits in our Honda. This kit has been on the market for almost eight years and many thousands are on the road with an excellent reliability record. The pistons are manufactured in Japan by the maker of the original Honda pistons. The rings are from the Honda 350cc twin and are, if anything, better than the 750 rings. This kit's piston pins are also borrowed from the 350 twin for the same reasons: reliability, strength and low price. The 836cc (or 811cc) kit retails for $179.95 and is available from Action Fours or R.C. Engineering. The Honda's weakest link is its connecting rods. If the red-line is observed and the peak power is kept to 75 horsepower or less, the stock rods are fine. More power will mean splitting the cases and installing heat-treated or aftermarket rods, either of which is expensive.

     there's lot's more

  WONT MORE
Adding a high-lift, short-duration (torque) camshaft will improve the engine's power potential enough to take advantage of the extra displacement while lowering cranking pressure so that the engine will be able to digest today’s gasoline. The cam is not necessary, but it is nice. Again we turned to the proven performer, an R.C. No. 295 cam. This cam enhances the broad power-band of the 836 kit, is easy on valve gear and is not costly ($141). R.C. valve springs ($49, No. 1050) and stock retainers were used to keep things under control.

A cam won't do any good if the engine can't get air. The Honda's airbox and carbs are fine; the 28mm Kelhin carburetors will pass more air than the excellent Mikuni 29mm smoothbores. The stock paper air filter, however, is too restrictive. A K&N cloth filter will take care of the intake's needs.

                             YES there's more

So if I want to build one with say, 125HP, I should get forged pistons, steel forged crank, and some forged high strength rods along with the better cam and high flow carbs? Next year I will have to start down that road. :) Good post, thanks for the info!

Stock Honda exhausts for the 750 four changed almost continuously over the life of the bike. The first were rather loud and not very restrictive; excellent for making power. They became quieter, more restrictive and heavier. There are few of the original, high-performance exhausts left. Either they have rusted out or have been replaced by four-into—ones. The late Honda four-into-one pipe was rather stuffy and very heavy as well — and it robbed ground clearance from the right side of the motorcycle. Aftermarket four-into-one pipes are lighter, longer-lived and usually make more power than the stock item they are designed to replace. One of the most successful of these collector systems was also the first: the R.C. Engineering four-into-one ($219, chromed). Although it will not give as much ground clearance as the Kerker (also $219 in chrome), it is better than the Honda four-into—one pipe. Both pipes will make a lot of power and remove about 20 pounds from your bike.

Jetting for either of these pipes is rather easy. Simply install the K&N stock replacement filter, change the pilot (idle) jets to No. 35s, go up two sizes on the main jets and adjust the pilot-air screws out one to one and one-eighth turns. Be sure to synchronize the carbs. (See the Feb. 1981 issue of Motorcyclist.) [Anyone have a copy?]

Have you tried contacting the publisher's reprints department?
They may have it available.

Haven't messed with yetNot sure what i can get out  NOPE NOTHING

A February 1980(i wasnt even alive yet!)magazine with an article on how to install tapered roller steering bearings...that didnt take long.

p.s.- that goldwing needs to be put out of my misery

[Daddyman]

Dude Ive seen some cool Goldwings bobed and cafed

[TOOLS1]

I have wanted a naked Gold Wing ever since I saw Bob Seger sitting on one. It's on the Against The Wind album cover. Funny thing is, that very same bike was , for sale here in KC last year, and I did not have any money at the time.

I like the 1st generation Gold Wings too. I had a friend in Seattle that made a real nice chopper out of one, just beautiful, wish I had a picture of it.

A neighbor of mine has a couple of old ones and an early trike conversion in his barn. He hasn't touched them in the 12 years I've lived here but he won't sell them. He's a hoarder. He's got a couple of '49 mercs, VWs, old pickups, all kinds of stuff, but he doesn't do anything with it.

Dont get me wrong guys,i dig gold wings too.Just not the Caddilac editions.

 1980 is Perfect parts bike for my F2 were I've gotten caliper and stuff

[MRieck]

 Mark...you will need all those things plus a ported head. 125 is very high HP for a normally aspirated CB. 1000cc will get you around the 105 to 110 HP. Let me know when you want to get started as I can supply you with all the parts at discount prices, porting and most importantly advice.
