How the f##k do you remove the airbox?

Hi Guys

Got an 700 Maxim, how do I get the airbox out? Looks like I hvae to cut it out.

 

If you remove the starter, the carbs, and the exhaust system, you can undo the front engine mounts allowing the motor to pivot forward and give you room.

Don't cut it up; that way you'll have it when you realize you want it after all.

 

What benefits are there to the airbox over K&N Cone Filters? I have 4 sitting in my garage which would look great on it, and improve airflow me thinks.

 

just do a forum search for pod to get a whole lot of argument about it.

 

I cut mine out, but it already had a big hole in it. The big problem with pods on these bikes are the constant velocity carbs. Some have had good results with velocity stacked pods which will still involve changing jets. Or you could get a decent set of round slide carbs for about 350.00 that are alot easier to deal with and handle air & exhaust mods better.
May cost more than you want, but will be less of a headache.

 

I don't know about the 700 Maxim, but there is no way to remove an airbox from a 1982 750 Maxim without removing the engine, I sat on my little bench turning the damn thing every which way, but to no avail. I removed the carb boots from the head and engine mount bolts, no help there. It seems Yamaha designed it to be removed after the motor was gone.

 

Uh Oh This looks like another Starter clutch thread LOL

 

Wrong! it's an airbox thread.

 

It is my experience LVSteve is correct I removed engine side carb boots, starter, headers, engine mounts to sag the engine forward, .... still cant get a dnam airbox in or out of a 650 Seca or 750 maxim. I did find a bike lif
but Id rather go through what I went through to install one than go the pod trials

 

Yes understood...what I meant was like the starter thread, there seems to be debate on whether its possible :wink:

 

I get it now Adrian, you just didn't phrase it right.

 

It's possible depending on the bike. It can be done on the 550s and we had a member that was successful using the same technique on I believe, a 700 Airhead, which is why I offered the suggestion.

I don't think it can be done without removing the engine on most of the 650/750s, but I can't say for sure.

Yes, the K&N "pod" filters will increase airflow, and that is exactly why they cause tuning headaches with CV carbs. These carbs need a finite, regulated airflow to produce the correct responses, if given an unlimited air supply they don't work well. As above, do a forum search for "pod filters" before you shoot yourself in the foot.

Once again, I will tell you how I get them out when I don't plan to pull the engine.

I heat the sides and bottom of the square part, when the plastic is soft, fold it together and remove the airbox. After putting it back in, re-heat it and carefully unfold it and smooth it back out.

Thats actually pretty slick. And makes good sense too

 

That's great if you have the ability to heat it, I don't, darn it.

 

walmart has a decent gun for around 30 bucks. But home depot has a porter cabe thats better for about the same or not much more. They have lots of uses, this is just one I never considered and I should have (duh) the primary use for mine is to heat and form PVC condiut. Great for stripping paint too.
Got give it to Dave on that one for sure, bravo Sir

 

I know how to heat it, don't have access to electricity, not allowed to use propane; working out of a storage unit.

 

dry ice and a hammer

 

I was able to install an air box on my 83 750 Maxim. I'm sure I could remove it and re-install it if need be. You need to pull the carb manifolds and the front mounting bolts for the engine. I had just enough room to fit mine in. I wish I had taken some pictures of that. I just remember it all had to go in from the right side of the bike
