At the end a wonderful ride yesterday I discovered My rear cylinder Base-Gasket is leaking. So far the only ill-effects has been a 3 "coughs" which is pretty unusual for my well tuned Cyclone. After some thought I think when the snow hits I will probably tear down and freshen up the top end with a performance package, Untill then (as long is it runs fine) Could I possibly do any damage by riding it??? It is my main transportation.

FWIW my Blast weeps at the base gasket and it has for over a year. I don't think I'm damaging anything.

I would say mine is more than weeping. I rode about 125 miles yesterday and when I got home the whole right side of my engine was covered in Oil and pooled up in some nooks and crannies throughout the area near the bottom of the pushrod tubes. Thanks for the reply though. And for anyone else who might read this, I am sure the leak is at the bottom of the cylinder. I first located the leak right after my ride because I could see fresh oil bubbling right at the base of the cylinder. Then for verification I completly de-greased the motor. Only after 2 minutes at Idol the leak presented itself at the same spot I first diagnosed. The bike does hav 44k hard miles on it and am currently running the stock breathing system.

In that case I would be worried that something has broken, causing both the leak and the cough that you mentioned.

You might check the vent hoses. It sounds like the case is pressurised if it's squirting oil out that quickly. I forget exactly how a cyclone breathes. I think there are two breather bolts in the sides of the heads. I don't remember where they feed. If thats the problem, you might not need to do any engine work at all.

The breathers are on the sides of the heads and they route back into the infamous "breadbox". When I get home I'll take a look at the routing system for problems.

Yes. In the last 2 days I have put around 100 miles on it and I believe the "cough is getting worse" I hope that it is a case of bad gas and not as a result of the gasket leak. I've decided that I'm going to continue riding untill my leg starts getting wet with oil. As of the last 2 days it is leaking but not bad enough to make me park it. Yet.

I do gotta mention that last night I picked up a real cool heavy-duty chain pulley system from a buddy of mine that will hang from my rafters while doing the winter top-end freshen up. Sure beats ratchet straps. I usually use those for tire changes but I figured I would need something more secure since the bike will be hanging for sometime. He said it was an antique dating from back in the 40's. He told me I could have it free of charge because it has sat in his garage unused for over 20 years. Now i need to start collecting other specialty tools because I'm going to attempt on doing the top end myself.

Open up that breadbox and you just might be in for a surprise. The external oiling and the occasional coughing just might be related. There's a reason many of us have re-routed our breather lines, and others have upgraded to XB style rocker cover venting. Simple enough to open up the breakbox to check, and to check for air leaks while you have it open.

Hot oil travels in mysterious ways, and much like a magician often has you looking in the wrong direction for an answer. Grab a milk crate, sit down next to the bike, open up the breadbox, have a sandwich, and ponder things for a bit.

Mickey,
No real specialty tools needed. Only ones I use are the bent allen wrench from American Sport Bike for removal of the intake manifold bolts and the shortened allen for the rocker box removal.
Oh yeah, a good torque wrench is mandatory.
You got the service manual right?

Shoot us a picture of the old chain lift. Lots of us around these parts dig old tools..


Also, ditto what Mike said above...

I do have a service manual and I also have a Snap-On inch and Ft lb Torque Wrench. It's good to know that I won't need much else. I do not have a digital Camera ( i Have and Old Cannon) but I will try to borrow a buddies so I can post a pic of my new pulley system. Did I mention how cool I thought it was??

I have a base basket leak, rocker cover leak, and a head gasket leak all on the rear cylinder. Nearing 30k miles, I'm expecting it. Looks like I have my winter project! But for the time being, it runs good.

Oil and wind do funny things. Are you sure it isn't just the rocker cover leak running down?
