Default Base Gasket Leak

How long can you let a base gasket leak go on. Yea its a PITA but cash flow is a little low. Its been leaking from the rear of the rear cylinder. At idle you can see it bubble. Leaking like that for about a year, 9,000 miles of riding.

That's one way to change the oil. That could depend on how bad it's coming out. Most of those gaskets are fibre/paper w/ a bead. Can't see it being a TC unless the o-ring is shot.

you can let it leak like that as long as you keep oil in it, personally, even if funds are low, id buy a cometic gasket kit 60 bux, and a manual. 30 bux and do it. besides a torque wrench, no special tools are needed and its very straighfoward. chad.

I found a Top End gasket kit from Cometic in Drag Spec. When I get her apart, what other bolt on's should I consider to get that "reliable" power. Emphasis on reliable, plan on doing Sturgis from SoCal. Or should I keep her as she was?

Well you'll have the heads off....Consider head work. Check your rocker arms,shafts,valve stems,seats,collars,springs. Freshen up your cylinders,rings.

the only thing i would do is maybe a ev27 camshaft, and rering the bike, also as far as a ring compressor, i found it actually more difficult to use a compressor around all the cylinder studs, so i have my pops come over, and i feed the rings in by hand, 100% percent success rate so far.

first leave the piston in the barrel, you can lift the barrel up enough to pop the clip and pull the pin. thats how i put mine back together, piston installed in the barrel and didnt nee a ring compressor just small screw driver. after all thats how they use to, and maybbe still , install the porsche 911 barrels, with the pistons installed in them then line up the pin. it really pretty easy to do. i had to heli-coil a front head bolt on mine. i know next time to coat the base gasket with permatix ultra grey, i dont care what any body says about not using it i know it works and havent found any one that had any problems after doing it that way.

I cleaned mine up and used some pourable silicone and it seems to have stopped it. That was over 2 years ago. There's a thread about some where on this site. That's where I got the idea. Cheap fix and it worked for me.
