VT700 Airbox "Hypercharger" Mod

went to remove airbox cover, bolts spin with some resistance but do not come loose, any ideas? Also does anyone have a procedure to remove the airbox, I need to get it out of the way to remove the rest of the wire harness.

Check out Lowe's or even Home Depot's sites.....I know ours on Saturday mornings have 'young builder' workshops my youngest son and my 7 yr old nephew found them very helpful. You might ask them if they have any idea's how to back out a spinning bolt.

If not.....try putting a little outward prying pressure on the item being held on by the bolt and 'slowly' start backing it out until it catches a thread. If still not happening.....sacrifice the bolt by removing it's head, slide the air box off and vise grip the remaining bolt piece out and visit your neighborhood Honda stealer for a replacemnt!

I remember seeing a few blower units for modern 1100's on the net someplace about a year or so ago, unfortunatly i got an 86 and there were no units for them available. Has anyone on here ever mounted a blower/compressor/supercharger on their 86 by any chance? Would be interesting to know how that works out.
May the eternal shadow always block the glare of the sun.

Can you achieve the right fuel/air mix by adjusting the factory jets, or do you need different ones?

Is it really necessary to have the butterflies attached to the throttle cable? I would think the vacuum increase of feeding a larger mixture to the engine would cause the vacuum inside the "hypercharger" to rise and open the butterflies?

What kind of air cleaner element did you start off with?

You will Deffinetly have to rejet the carbs with larger jets, adjusting the mixture screw just isnt enough. the butterflies would open on there own, but would not close. and you do want to restrict air flow at lower engine RPM's and throttle opening.

Now down to business...
ase175 & js83shadow, thanks for the comps!
As far as suggestions....what ever you want to do. Really, these bikes may be old, and you might not be able to get all the goodies on the market today, but don't let that stop you.
Just get a picture in your mind of what you want your bike to look like and do it.
SeaBass is makin' his own bars, and lang lopped off his guage cluster, and as you can see I hacked up my airbox.
If you can make something work, like mirrors, side mount, then go for it. :thumb:
Your imagination and drive to get the job done are your only limitations...and sometime the pocket book too.
If you've got questions, there are more than enough folks on here who can answer them.

Nice mod, Very creative, clean looking, Great job!

I removed the airbox from my 1985 VT700C. I added these clamp-on air filters from eBay. I also relocated the fusebox under the tank.
