Performance parts for my 750 or should i just buy bigger

[Shadow Coyote]

Hello everyone,

I have an 07 Honda Aero 750. It is currently totally stock. I was just fine with my bike when i got it, but since it is my daily driver i have found myself getting really bored with it. I just want more oomph and muscle out of it. I didn't think i would outgrow the 750 so quickly. Now i find i just feel too big on it or something. My bike doesn't get anywhere near as good a gas mileage as it used to, maybe i just push it too far, but i still need good gas mileage and some performance out of a good cruiser bike.

I only owe a tiny bit more on my loan, so it is almost paid for. If i keep it, i will need some performance mods for it to give it alot (realistically speaking of course) more power and guts. I don't have alot of money to work with, so i could definitely use some advice. Am i better off keeping the bike and buying some performance mods for it, and if so, what mods are best. Or am i better off looking at a used bike with larger displacement.

I would really like to customize whatever bike i end up with and really make it my own, so i would like to be sure i get something that can be dressed up abit and customized or if i keep the current bike i need to know it's worth it before i begin messing with it's original design.

Any help you all could share with me would be really appreciated. Thank you.

Performance mods most likely won't give you what you want, V twin cruisers are not like a SBC, you don't add pipes, intake and carb and pick up 30hp ...... perhaps you should be looking at a sport bike

What is SBC?
(Sorry if it's a dumb question)

Thanks for your reply.

I don't need a racing bike, and i don't need to be doing 110mph or anything like that. I can get up to about 90mph before the bike starts to slow down and stop accelerating, if i keep it up, it sounds like it will explode. At first i was dissapointed that i couldn't reach the 100mph mark, but i realized that i really didn't need to do 100, so i am okay with top speed. But accelerating from 65-80 seems to be sluggish also. The bike just seems to not have very much get up and go. Sometimes it does, but other times, it just seems to be struggling to work up to a speed. I just want to get to the speed quicker and have better response.

When i throw extra pounds on the back (backpack with books) it gets even worse. I would like to be able to carry a passenger occasionally (i know it's probably not a good passenger bike, but i would like to use what i have available), but seeing how it has been acting, i don't want to hurt it by putting even more strain (weight) on it until i can find a way to make it work better.

Also, is there a way to reduce the drag affect the shaft seems to put on the bike? Just curious, because if i just take my hand of the throttle for a few seconds to scratch my back it seems like i will drop 20 mph in no time at all. It's kinda annoying. If there is no way to reduce the problem than no biggy.

Thank you.

SBC is a "small block chevy" V8 engine, and you do mention getting up to top speed quickly numerous times, not one of the "top" attributes of a V twin cruiser, that's why I mentioned sport bike, that is one of their "top" attributes. You wouldn't want to buy a bigger V twin and and up with the same disappointment.

As for the drag, that is most likely the gearing more then it is the shaft drive.

Thank you for the explanation of SBC.

I guess i wrote it poorly. The top speed isn't real important to me, and jumping right to high speeds isn't real important to me, a good steady climb to speed is important to me. The bike seems to be sluggish , not always, but off and on, it just starts to feel bogged down and it slowly rolls into it's speed. I know it's not a sport bike, but i just want a little bit more oomph without the occasional bogging down. It doesn't die on me or anything, but it sometimes sounds like it. Sometimes it runs awesome, quick enough for me to be real satisfied, but other days it just doesn't run the same. I was mainly looking for a way to increase performance a bit and just make the engine run stronger. If it runs stronger it probably won't bog down under normal riding conditions and will always give me real adequate performance, or at least that's my thinking at the moment.

What kinds of mods are available for the '07 aero 750. I don't care about the exhaust note or things of that nature, so i will probably keep my pipes just the way they are, but i want a strong healthy engine that runs real good all the time. . I have heard that hyperchargers will up the performance, but i don't know anyone with a hypercharger so i don't know anyone to ask about their experience. Same thing goes with the air intakes, filters, and things of that nature. Do they really help the bike run stronger?

I don't know alot about bikes. I like riding 'em and i am slowly learning more as i read new things, so if i say something stupid, please correct me.

Thanks again.

To be honest there really isn't much you can do that will give you more then 1-3 HP MAX/at best, that's just the nature of the V twin, there's not much you can do with them that will give you big gains. A hyper charger is just more air, with that comes rejetting, and if you let in more air, you need to let it out (pipes). If you want to get what ever gains there is you need to add at both ends to achieve it, and most agree that the best bang for the buck if you're looking for more power is upgrade the bike .. because unlike a SBC, you can't just add a few bolt ons and get good HP increases.

But to be honest as you explain your situation further it sounds you may have a carb tuning/gas/air problem if it has inconsistant performance?

[Shadow Coyote]

What would be good tests to perform to find out if i do have a carb tuning/gas/ or air problem?

Would this be something i could do with some simple instructions or would i need to find a mechanic to check for such problems?

If it is a mechanical problem, than a good tune up should give me alot better performance right? I still have less than 2000 miles on it, so i still have like 7 or 8 months remaining for warranty if there is something serious.

Thank you for your help. I appreciate it.

Shadow Coyote,
You're somewhat limited as to what you can do to gain performance!
It's not so much that your bike has a smaller 750cc engine, but the fact that your Aero is shaft driven and only has one carburetor.

When compared to the 750ACE or Spirit 750 (both have chain drives and two carbs); on your Aero, you can't change the final drive ratio, and you can't tweak each individual cylinder in terms of fuel/air mix for optimal performance. With only one carb you are forced to find a happy medium that satisfies both front and rear cylinders regardless of what each cylinder is calling for in terms of fuel/air.

Even if you did have a chain drive and two carbs on your Aero; you still wouldn't find gobs of power. I can tell you, the 750 engine responds well the right combination of jetting, pipes and timing/ignition mods. But, in your case, without being able to change the final drive ratio; (via-chain drive) those mods might not be as effective.

On my 750ACE, I raised the final drive ratio (numerically lower) by adding a smaller 37 tooth rear sprocket, added Dial-a-Jets, K&N Air Filter, Aftermarket pipes (Cobra LoBoys) and a Dyna-3000 Hi-Performance Ignition Module.

I'm satisfied with the power increases from these mods. It's no rocket but it does have a noticeable difference; especially noticeable when carrying a passenger and luggage.

Thank you for all your help guys. I think i will end up keeping it the way it is. I can't afford to take the loss in value if i tried to sell it. Wouldn't be able to even have a good down payment on anything yet. I will probably just buy something bigger in the future when i have more money set aside. Gives me more time to shop around.


I think my current bike just needs a good tune up.
