VF500F Rear Exhaust Pipes - Removal

Hi All,

Does anyone have experience removing the two rear exhaust pipes (with the engine still in the frame) on the VF500F?

There isn't very much room in there and it looks to be a herculean task to line up a socket. I am thinking the mono-shock needs to be removed to provide access...

Any tips on how to go about this would be most appreciated!

 

Oh man.....I remember how much of a pain it was to remove the collector....I don't even wanna think about removing those rear pipes.

Break out the beer and the swear-jar.

 

The front pipes, collector and mufflers were no problem but those rear pipes are a bit daunting!

You really can't access the inner exhaust collar nuts from the side - I'm thinking that I will need to remove the mono-shock to get a good line on these.

 

Your bike is so clean...I wanna lick it.

 

Thanks,,,,I guess... ;-)

They are definitely easier to work on when they are clean.

 

sadly, removing the rear shock is the method I had to use...that and a BFH

 

Thanks, this seems about right.

Funny, in the FSM ('84 copy) I couldn't find any reference to the removal procedure for these...

 

Why do you need to remove them? Curious. I didn't even try taking them off while the motor is in the bike. But in my case I was pulling the motor for head work anyway. I often thought about what would be involved. Pulling the shock and the associated hardware to do so isn't a big job. I would say less than 15 minutes past where you are in those pics.

Do you ride that bike? Man, it's as clean as my new one!

 

This is a good question...most of the aftermarket exhausts that I have seen use the factory downpipes.

So why are you trying to remove yours>?

 

For maintenance.

The rear downpipes and the mounting hardware have a some rust on them and I would like to clean them up.

Removing the mono-shock looks to be the best strategy then...

 

I am kinda new to the whole interceptor myself got mine mid last season for a deal (running on 2 cyclinders at first cause of loose coil power cable for a whopping $500 with 3 boxes of spare parts)I am doing the same thing on my bike (84 vf750) and I was curious if it could be done without removing the motor and if so thank god. I dont honestly know the condition on the rear pipes. The front pipes and collector were all rotted so I am guessing they are kinda beat up. I bought a parts bike with a intact very good condtion full exhaust and the rears on this one still had the heat shield on them. if you get this done on your bike PLEASE let me know its all I need to get done on my for the coming season.

You can easily access the rear headers by removing the mono-shock.

Another thought, perhaps a flexible socket extension will work without removing the mono-shock. I haven't tried this but it would save a bit of time.

Here is an example of this tool:

TM61A, Extension, Flexible, 6"

On a side note, if your mono-shock is original I would recommend replacing this with a shock conversion upgrade. The original shocks weren't the best when they were new and are dog-eared after 25 years.

Good luck with you project and let us know how you make out.

 

Is there a link for the mono shock upgrade somewhere?

 

Daugherty Motorsports - Motorcycle Suspension Performance and Modification

It's not really a cheap bolt on mod but it would make a world of difference. Jamie Daugherty on this forum is the mastermind behind the mod and I have yet to hear a single bad thing about the man OR any of his mods.

 

ok excellent I will look into his mod thank you for the heads up

 

Having a longer hose for the shock's reservoir (in this case an F4i shock) is key:

 

what is typically involved in a mono shock upgrade? invisable cities unless I am misundersyanding you are you saying I could pick up a f4i shock and bolt it in but would just need a longer hose to the reservoir or is there som fab work needed to be done. ( I havnt heard back from jamie yet )

 

He was only mentioning that because due to it being a CUSTOM part so its not guaranteed where you put the reservoir. The longer the line is, the more places you could mount it.

The real reason for the price of the mod is the fabrication for the mounting points of the shock along with the fact he will go by what people's weight will be when riding and use different springs accordingly.

hope this helps

 

I removed the swing arm not as hard as you might think and whole bunch of room when you do that. Also be careful I broke a stud first time I removed the exhaust. Is this the system I sent you?

 

yup helps a bunch and ty
