Building 1100/1200 block, 1000 head engine
Hello, everyone.
So as you probably know, my engine is toast....
viewtopic.php?f=1&t=64528
So I've decided since I'm gonna have to replace the motor, I might as well build a fast motor.
That said, I'm gonna need a lot of help and advice, as I'm going to be doing all the work by myself.
So first things first:
Which block/head combo should I go with? For me, revs are important, and I really don't need to go above 120 mph. But I'd like to have optimal acceleration and performance between 20mph-100mph.
I also don't have any experience with metalwork or welding, so frame mods may prove to be problematic.
Let me know what you all think. This is gonna be a long thread a long time in the making, but its happening. Thanks in advance for all the help.

honest opinion? For what you want? Just put a stock motor back In it. Stock 1000, 1100, or 1200.

My only concern is how high the engine revs. From what I understand, you're saying that even with the loss in revs, I'd still be better off with just a stock 1100 or 1200? If that's the case, then I guess I should just put a 1200 in there and call it a day.
If I do that, is there something I need to do with the final drive?
Also, how do the electronics hook up? I'm assuming that there's differences between a 78 and whatever 1200 engine I get. Are there wiring diagrams somewhere?
Again, I'm gonna be asking a lot of novice questions, so please bear with me. And thanks.

Re: Building 1100/1200 block, 1000 head engine
I’ve done it. It’s work with no real book on how to do it. Benefits of 1000 heads on a 1200 block are unproven in any meaningful way. I’ve not seen anything but seat-of-the-pants opinions. Until someone does some strip, track or dyno time, it’ll remain like that. My gut tells me what you gain at high rpm you lose at low rpm. The increase in torque makes up for it, but may not better it by a lot.
Having done it, my opinion—- get a 1200 with the frame attached, the wires attached, etc. The 1000 is a light duty bike with a wobbly spindly front end. I did it because I found a 1200 for $120. Since then I added a different front end, a different final drive and had to mess with carburetors more than I ever wanted. It keeps me busy, but if I just wanted a good Goldwing ride, a stock 1200 is hard to beat.
Parts an adapting parts cost moolah. It adds up.
If you’re serious, an 85-87 will bolt in without much modifications. The 84 is more work framewise.
Cyborg likes his 1200 in a 1000 frame. I believe he bumped up to a 1200 front end too.

Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.

1000 frame..86 engine, (ign pickup in the front) coupled to the 1000 rear drive,...complete 1200 front end. I also converted the swing arm to a mono shock. Very fast, very nimble in the curves

This is sounding like a lot.... extra power is nice, but I'm thinking a stock engine replacement is the way to go. Grrrr......

Re: Building 1100/1200 block, 1000 head engine
In that case, I'm assuming a whole 76 or 77 motor would be best, if I can find one. Is that a direct swap, or are there minor differences?

Re: Building 1100/1200 block, 1000 head engine
What about work that can be done to the motor itself? Are there services for porting and polishing the heads? Is it a waste of time?
Or should I just enjoy it for what it is?

lol. In the end, it's all about intimacy with the machine. If you want to drag race or run with the sport crowd, it's probably wise to start with a different base machine. If it's that intimacy you crave, the sky's the limit. There's a lot of satisfaction to be had with these flat fours in touching all those secret spots.
Sheesh. Careful, this is a family site!

If speed is your goal,...start with the newest, fastest, production bike. If you just want to tinker cause it makes you happy, put in the shop time, and learn as you go. To some that is the fun of the "hobby".
if you rely on others to experiment and figure out the details, then you are missing the point, and need a new "hobby". To me, motorcycles, and engineering them, is not life and death,.....its more important then that.
