Title: oil leak @ vert cyl head! Post by: booger on July 07, 2008, 03:06:20 PM '06 S2R800
found an oil leak at the vertical cylinder head to engine case gasket - 1) is this common? 2) what causes it? 3) how much is it going to cost to fix it? It's not the breather, already scrutinized and found that out. It's definitely coming from the cylinder head gasket. I also found fuel leaks at the fittings under the tank. These leaks occured while the bike was on it's rearstand in the garage. I'm superannoyed. Title: Re: oil leak @ vert cyl head! Post by: printman on July 07, 2008, 05:08:14 PM Is it still at warranty?
The base gasket has to have the entire topend removed. Not that difficult, but hope its on someone elses dime Not sure on the fuel leaks Title: Re: oil leak @ vert cyl head! Post by: spaugh on July 07, 2008, 07:36:59 PM mine has a small leak on the vert head too. I'm not even gonna worry about it since it isn't dripping on the floor and I am not loosing any oil. Just a few drops on the top end here and there.
While we are on the subject. Is is possible to put in a thinner top end gasket to get a little more compression? I like my s2r 800, but wish it had a bit more juice.

Post by: printman on July 08, 2008, 02:18:13 AM Not sure on the 800's or any of the S*R's, but the 900 doesn't have had gaskets, just a few orings and a machined fit.

make sure your fuel leaks are not running down and looking like a head gasket leak, fuel can pick up dirt along the way and look pretty dark. You can change base gaskets to set your squish clearance, done right = more hp. Done wrong can have the piston hitting the head. If you give yourself at least 1mm clearance you are safe. If you are the original owner you should have no problem getting the bike warrantied, If you are past the 2 years you still may qualify for a good will warranty. I would ask first. Title: Re: oil leak @ vert cyl head! Post by: booger on July 09, 2008, 08:18:33 AM According to the parts manual it's a base gasket. I'll be taking the bike to the shop soon. I'm the third owner, so I think I can forget about warranty coverage. Bummer.
Title: Re: oil leak @ vert cyl head! Post by: clubhousemotorsports on July 09, 2008, 04:25:24 PM It should only take them 3ish hours to do the job with little to no parts.
I have done the job in less than 1 hour on race bikes but that gives them plenty of wiggle room to play with. [thumbsup] |
