Motorcycle, MORE power!?

Question

Whats up!!
Ok. I added a performance exhaust and I plan on adding a K&N filter to it once I get to the end of my current air filter's life span. Can anyone reccomend any further performance or power enhancements short of buying a bigger bike? :)
Also, it is a honda 750 aero, incase that matters. Thanks tons.

Answer 1

If you don't want to mess with the engine internally, then you really only have a few options with things like carb and exhaust mods.

Putting on a lower restriction exhaust is a start, next changing to a lower restriction filter like a K&N or Uni filter is also good and then of course you will have to re-jet the carbs richer to compensate. This may involve some experimentation before you find the ones that work the best. If you're running CV carbs, you will probably need to increase the jet size of the main and pilot jets as well as shim up the slide needle. Check with your dealer on how to do this - it's pretty simple...

Next, a lot of factory bikes come with airbox restrictors - that is the airbox will have openings inside that are smaller than what the carb needs to breathe with. This is done for several reasons including noise, fuel mileage, emissions, smooth power, etc... If you can open up the box, you're engine will breath a lot better.

While it won't produce more power, a smaller countershaft sprocket will increase your speed off the line.

Beyond this, you will have to get inside the motor and spend some serious money. That would include high compression pistons, a hotter cam, head and valve work, etc... For a 750 Aero, it's probably not worth it.

good answers mostly. i am assuming u have a fuel injected bike. if so, u need to have the dealer add a power commander, put in the proper map for the ecm, and for best results, put the bike on a dyno to get the air/fuel mix dialed in perfectly. it would be best to do this all at once; pipes, air cleaner, then the remap. this is what they call a 'stage 1'.
what 1 said about changing the sprocket is right. i saw a guy talking about something like this on harley chat group message board that i got a link to in the mail awhile back. for a bit more power, u need to put on 'stage 2'. this requires changing the cams to either high performance for high speed, or cams that are geared to put down some stump pulling torque. the heads are also usually ported for better air/exhaust flow....and a much better breathing engine than with the stage 1 alone. with this added power and torque, it would be a good idea to beef up the clutch plates to something more heavy duty.
if u have the coin for it, put on the stage 3 after. this requires alot of internal engine re-work. pistons and jugs are typically bored out alot more, the rings, valves, etc....everything inside the engine would be reamed out a bit bigger. upside, u'll have a deceptively powerful bike, downside....that wont come cheap.

I own one of those too. I put "Cobra" drag pipes on mine as well as installed a K&N air filter. To answer your question, all thats left to do is purchase a jet kit for the carb. Your pipe manufacturer recommends that anyway. It increases the power and sounds great. I like loud.

Answer 4

Trade it for a 1300. Seriously, modern bikes are very complicated due to all the emissions crap. You are likely going to spend as much money trying to sort the bugs out as you would making payments on a bigger bike.

Answer 5

Most sensible motoring organisations will tell you that speed doesn't kill, bad driving does. Our speed limits are the things that require changing. The limits were imposed when most cars on the road had brakes made of rubber and the cars were more likely to kill you in a slow speed crash having no seat belts of safety equipment. I travel to France and sometimes Germany in my vehicle and years ago my Dad used to ride to Germany a few times a year on his bike. Wouldn't be worth it if all we could buy here are bikes that wont brake the antiquated 70 barrier.

Answer 6

Is that bike Fuel Injected?? If so, you'll want to get a Power Commander to go with that pipe and K&N filter change... if not, you will want the carbs rejetted for more power and usability of the pipe!!

Also, if you dont mind losing top end, you can change sprockets for more low end launch offf the line. Easy to do too...just order a larger rear sprocket or smaller front!

Answer 7

Buy a "jet kit". It will be pre-calibrated to work on your bike with the aftermarket exhaust and air cleaner. No fine tuning required.

Answer 8

Use BMC filters instead of K&N.. they are much better.
Also, get a power commander or change the gearing.

Answer 9

you want to put a smaller sprocket on the front not larger... go 1 tooth down and that should feel torquier!
the other thing is to put a dry nitrous kit on it and Hang ON!! throw a 20-30HP shot in it to start... this is very easy if your bike is FI... if not you might have to fatten it up by putting a jet kit in it...
take it to the dyno and get it tuned that will help!
and you might want to try BMC race filters over K&N, just another option...
