Hi folks
Within the past 2 months I bought a 97 Valkyrie after riding a Shadow for 11 years. The Valk is such a dream to ride in comparison! However, since I have put 2k miles on, I note that she burns blue smoke primarily out of the right exhaust. I changed the oil, check it before every ride, and it does seem I am burning it. I get condensation smoke out of the left pipe when I start, but after a few miles I get blue smoke / oil smell on revving as well as that great oil smell on coming to a stop. I have probably added a quarter quart 10-40 no fuel saving oil into the bike in 2k miles.
I have read through a lot here and will be looking to check the right side plugs / valve stem seals depending on what I see in the plugs. This Valk, even with my miles, has just crested 20k miles. The previous owner was proud to mention how it would peel out in third gear and I am wondering about the clutch having sheared rivets on the plates. I don't have folks to ride with, so I only know I blow smoke at stops / lights and revving, as well as that oil smell whenever I come to a stop.
My question is primarily this: if you were to open the clutch and saw sheared rivets on clutch plate B in particular (which, if I am not mistaken, is the main culprit for sheared rivets), would you replace just that or just replace all while being in there otherwise depending on how they look?
And or what else could I be missing?
I could be putting the cart before the horse as I haven't yet had time to get in and take a look at plugs etc, but this bike is incredible and a several year long dream come true - post Shadow years. So Question 2: any other thoughts or tips to where / how to check why I am burning oil and blue smoking on rev primarily on right pipe?
Thank you all!

I’m not familiar with the additive in 98Valks post. it may be a great product but I’d be very leery of friction reducers in a wet clutch engine.
As for your rivet worry, if the clutch feels normal, you don’t have the rivet problem. The clutch lever will feel wrong when pulling on it.

I have had some popping to N from a shift to 2, but nothing else shift related really. I will be pulling plugs tomorrow, I did find some oil spit out next to the mid right plug on a long ride so I am kind of hoping it is valve stem seals on that side rather than clutch. Thanks! |

It doesn’t sound like sheared rivets to me. Have you drained the drool tube ? Are you checking the oil level with the bike upright and the dipstick not screwed in ?

it is not a friction reducer. it is a high synthetic ester oil product. esters clean out engines. they have a protocol and cases of it being used in motorcycle engines. |

I have not checked the drool tube. Where is that? Also, thanks for the head's up I may not be looking at the clutch. For the oil, yes the bike is upright and unscrewed dipstick. It is an after market dipstick, so my first check I drained the oil and measured my qts, refilled and checked the dipstick reading to know the lines on it and know I wasn't misreading. |

Look underneath. It's the only tube with a cap. Remove the cap, drain the drool.
Mine usually only have a half thimble full of gook, but after an all day rain ride, it can be way more.
Replace the cap, use the clamp.

And as for the oil next to the spark plug, as well as the popping when shifting: you might need to reploace the o-rings on the short intake tubes going between the carb and cylinder head. They become rock hard, and leak, before 20 years in my case. Vacuum hoses also need replacing by this time, too.

Have you given this a try? If so, what sort of results did you get? |

Else, it's been raining here for what seems like an eternity so I haven't got to pulling through the rest of the bike to figure out where it's coming from. |

SOMETIMES flushing an engine will cause more problems. It can wash out seals and gaskets. May be better off doing a couple oil changes before condemning the engine. P/O may have been lax on maintenance. Use oil specific for this engine. Do not buy discount oil. Post your local as there is someone knowledgeable near by. We never disclose those in witness protection.
