New owner of 93 REAL FRUSTURATED

Hi guys, I am Jeff, the new owner of a 93 in Georgia that had to do the stator replacement and find some new plug wires as I broke one.... Well first the good news.. After a week of nights everything is back together. I had to drop the coolant 3 times as the first time I filled it up, the rear cylinder coolant pipe oring leaked. Time #2 it was ok but the front now leaked. Time #3 was the charm... no leaks... Now today I finally got the pipes back on and tank on. After triple checking fluid levels, for any oil, coolant, or fuel leaks, I hit the starter... after about 4 seconds, it fired up and settled into a nice fast idle at 2k with full choke.... No leaks no stumbles, IT"S ALIVE!!!!!!!!!

Now for the bad part... I noticed a little smoke coming from rear cylinder but thought it was oil or something in the pipe... Well then all of a sudden, the fire hose turned on from the rear pipe...... The oil in the sight glass is choclate milk color and i have a 5' streak of blown out coolant at the back of the bike... Front pipe is dry and no smoke..... Ok so I guess it's a head gasket....

What's involved in replacing that...Please tell me the motor doesn't have to come out again...Should I replace both when I do this? Lance in Buford, can you do this? At this point, I am at my wits end and ready to dump it for something more realiable.........HELP

If it is a head gasket (there are other possibilities) then yes, the engine has to comeout again, the cams have to come out, along with a bunch of other little parts to get the heads off, plus you have to deal with those awful cam chains, and retime everything when you put it back together. No fun at all. It is not something I would try to do in a hurry, if I needed the bike for transportation, I would look for something else. I am a professional auto mechanic, but tearing into the Vulcan 750 engine is something I would take my good easy time with, especially since I have never done it before. Lance could definitely do it if he is nearby.


And yes, I would do them both, if that is what the problem is, while you have the engine out. And I know people here are getting tired of hearing this, but someone new is always coming along. If anything can be considered reliable, the Vulcan 750 can. I put over 80,000 miles on a '93, and currently have almost 45,000 on my '02. The ONLY problem I had was with the '02, the automatic cam chain tensioners messed up, but I solved the problem permanently (I hope) with manual cam chain tensioners. Jerry.

I am a motorcyclist, NOT a biker.

From what you described it could be a head gasket or the impeller seal failed. A cylinder leak down test will confirm the head gasket.

The Real Frustrated 93' Owner dropped of the bike, doesn't look good.
It's not the impeller seal so that leaves the head gasket, cracked head or cracked cylinder. I won't find out until the end of the week when I am done with Asbrand's bike.

What ever it is we'll have him back on the road in a couple of weeks.
