HYA MICK!

GOOD NEWS!......I finally resolved the "failure to launch" issue with the old V Star! After screwing with the carbs for months and months, I finally found that the "pro" that had them last, did nothing for me. I started from square 1, and was able to find a very serious vacuum leak  due to the 22 year old carb boots being cracked like the bottom of a dry lake!

I replaced them, and was able to fine tune my bench sink to the point of having a great running bike again!

I still have some popping on decel, but having a little fluid from my homemade manometer sucked into the engine revealed that the front exhaust header gasket was shot.  Have them on order, and looking forward to getting a couple of good rides in before the snow flies here in NY.

Quick question though: there was N-O gasket of any form on the front exhaust/header pipe union. And I mean NONE. The connection is even different, as in the rear connection has a collar for the gasket to hug, while the front has a flat surface on both the pipe and the cylinder head. The gaskets come in identical pairs, but I'm confused as to whether I should put one in the front, or is some sort of sealant used? I'm quite certain that I should have found SOMETHING there upon disassembly. Almost to the point of being able to leave you alone, and forever grateful for all the help you have provided throughout this long and painful summer! You are a patient man, my friend.

There should be a gasket on the front as well as the rear.

Exactly what I was thinking, however, there was not and the pipes have not been off at the jugs since I bought the bike......new. I recently read a thread somewhere, in which the author made the same statement as I, and everyone came back with " there HAD to be one" "you must have lost it" "that's impossible" etc. Well, I 'm here to tell ya, the flange faces are as smooth as a baby's bottom, and there is no indication whatever that there was ever a gasket in there. I have put 153K miles on this bike and the exhaust leak is a recent development.

Now back to the question: if there ARE to be two gaskets, are they the same, or is there some difference? I see them in the schematics of parts books and manuals. They are each PRICED differently (the front one being more costly) but look the same to me.

I just don't get it.

If I remember correctly there are 2 on the rear and they are different from each other. 1 for the elbow to the head and 1 for the exhaust to the elbow. 1 of the 2 are the same as the front I just don't remember which.

I don't want to be THAT WISE A** but how were the oil and filter changes accomplished; I don't see an ORK or perhaps my eyes are failing me too. Could the dealer have lost the gasket in the drain pan at first service.

There most definitely a Jardine ORC on the bike. So I guess SOMEONE had the pipes off. The bike had 800 miles on it when I bought it, so...........

But that still doesn't explain how the bike has run flawlessly with the gasket missing for over 150 K miles.

No real mystery whoever installed the ORK lost the gasket and probably over tightened the cap nuts on the studs and they went undisturbed for all those miles.

WTH?! Bought new gaskets specific to my bike......don't fit! The inside diameter of the gaskets match the inside diameter of the head pipe, not the sealing flange!

Went to Autozone and picked up the FelPro #23588's that other riders have used.........same situation! There is no way they are fitting into the pipe to reach the sealing area of the pipe. I have attached a pic to ponder!

This bike (except for the ORC) was bone stock when I bought it back in 2000, and all I have done to the exhaust is install Jardine slash cut slipons, which does not alter the head pipes.

If that's your rear cylinder it takes a different/smaller one. That one fits into the head like in front but not the header in the rear. Most sellers are either unaware or unconcerned. I did find a set that included everything I needed and more but I'm not sure where. I think it may have been some Europeans on E-bay.

RIGHT YOU ARE! I found this out today when I finally went to the front cylinder and the gasket fit right in. Sadly, I will have to go to the dealer and pay 3 X what I paid for the pair jus to buy the one!

THANKS EVERYONE!!
