    I bought a set of headpipes and collector box for my 85 VF 759 F. I want to get rid of the Hindle system and return it to stock. Question #1: Do I have to remove the engine to install the rear headpipes? Clymer manual says you do.#2 The front headpipes have some dents. Has anyone had any success removing the dents or is it best to cut out the bad spots and weld in new pipe?

    I believe the '85 is like my '83 in that the rear cylinders had their own short pipes that went in to the collector box. When I put on my Vance & Hine headers, they used the existing rear short pipes, if the Hindle system did the same, it is a pain in the ass to tighten all the nuts, but I never took the engine out. I would make sure you have a universal joint for your socket set to get in there.

    Apologies if this is not applicable, but the 500s had double wall header pipes, something to ponder as far as the dents go.

    Ohhhhh! It is applicable! Double wall. That could make it very difficult. Might as well take out the bad pipe completely and have a new one bent up.

    You should Google the effects of dents in header pipes; apparently it makes very little difference to the engine/power. If it is ugly, well that is a different matter.

    I took your advice about going on the internet, Terry. Basically 3 methods to try. #1 Cap the pipe and fill with water, put it in a freezer. #2 cap and force compressed air into the pipe while heating it. #3 Forcing ball bearings (of an appropriate size )through the pipe while heating. Think I'll try the freezer method first since it is the easiest.
    Chime in if you have any other ideas.

    That's what I thought.

    This is the V&H set of pipes, the rear pipe on the right which used the stock short pipes. Even this method was a pain. I could get to nuts on rear flanges to loosen enough to mate up pipes and slide the header onto them. I do not see any way of attaching these pipes easily, if at all.on the bike. Have you found a stock system in good shape?

    On the 86 you pictured, no. But I have installed the short rear stock header pipes on a VF1000R (which should be the same as the VF700/750F) with engine in frame and rear suspension on. I got ahead of myself on a build, realized what I did and did not feel like taking shit back apart. Extensions, swivels and patience.

    Here's the $5o find. You get what you pay for. Note damage on front left pipe

    Bummer, as they look fairly decent otherwise. I'd rather have a couple dents than a bunch of rust holes most used collectors have. With the chin cowl on and radiator right there, no one will ever see them, right? Then you can keep your eyes open for a nicer set.

    I only want to pull the motor once (Actually, I don't want to do it at all ). The dent is squished quite a bit, to the point of being restrictive. When I get them apart Ill freeze the bad one with water in it and report back the results.

    Are you pulling motor to install exhaust? Like I stated above, I've installed a whole exhaust without pulling motor or swingarm.

    Yes, but you say it's not necessary. There are conflicting opinions on this. If you're right it will save me a lot of hours and skinned knuckles.
    Think I'll wait and see how the pipes turn out before I start wrenching. I've got all winter ( which just arrived this morning ).

    All I know is that I've done it. Can't hurt to try first. Extensions, swivels, flipping wrenches around for another 1/16th turn. And beer.

    Just like the Captain, I've done it. Takes time and tools but be patient.
