G'day, I am looking at a 1999 Valkyrie Interstate that appears to have some blued pipes. Is this normal for the Valkyrie's or should I steer clear?
Also, how many miles/km are you getting from your bikes. Is 99000 too high to start with?

probably just has been a little rich at some point or sat and idled too long. Aftermarket pipes blue easier since they are single walled and oem are double walled. 99k is nothing for these bikes. DDT (Bruce) has over 600k on his, so i would say 99 would be fine to start with.

The pipes may NOT be stock. Like gavin_sons stated could also be from a rich condition or too cursed much idiling. 125+++ miles on mine and the pipes came with a slight yellowish tint on them!  Mine starts and runs just fine!!  NOT even broke in yet on yours or mine!  RIDE SAFE. |

Try Blue Job and elbow grease on those pipes. Restored mine. Took a lot of rubbing though. Idling too long without fans on them discolored them. Good luck.

It's common to run the bike say monthly in the garage for 20-30 minutes instead of winterizing it. If you do that w/o setting up a fan, you get blue pipes. Otherwise - forgetting & leaving the choke on or otherwise running it significantly too rich or lean will also get them too hot and then blued. W/O such abuse - they won't blue indefinitely. Talking about the dbl-wall headers, OEM pipes here. All the others, if chrome they will blue no matter what you do. Except hi-temp powder coat or black paint them.

Bluing depends very largely upon what kind of pipes. Let us know something about what they are.
99,000 is certainly not too many miles but depending upon what kind of care it has gotten it's likely that moving parts such as bearings and U-joint and such may need attention or replacement.

Indeed on the Blue Job and a lot of rubbing. |

Photos would be helpful to identify the bike's pipes.

Thanks for all the replies. Bro and his buddy had a look last night. It has a little rash on it but nothing terrible. Runs real nice. Is carb syncing etc ever an issue on these bikes or are the carbs typically pretty trouble free?
Not sure how to post a pic on here yet. I can tell you they are slash cut pipes turned out to the outside.

Tell us more about the pipes. Are they six individual pipes that are slash cut and turned out? If so, they're aftermarket 2Brothers pipes and will blue due to single wall construction. If it's a single pipe on each side, slash cut and turner out, they might be OEM with the turn out added on. To post pictures, set up a free account on Postimage.org, once loaded on there from your computer it only takes 3 clicks to show them here.

... If so, they're aftermarket 2Brothers pipes and will blue due to single wall construction. ... Why do people who don't run TBRs seem to say that so often? I have 170,000+ miles on my TBRs and they're not blued. They are slightly golded at the headers but not blued. If your TBRs are bluing there is something not right with your carbs. BTW, those are not TBRs. The earlier explanations of why OEM pipes might blue do apply, fuel mixture or letting the bike sit idling for a long time. |

Yes as mentioned before, they are not stock pipes and single wall.
Also blue usually a sign of heat meaning lean or sitting at idle.
Willow hit it on the head.

BTW, those are not TBRs. The earlier explanations of why OEM pipes might blue do apply, fuel mixture or letting the bike sit idling for a long time. Maybe I should have inserted the words "tend to turn blue" with single wall construction. I was going by observation of numerous bikes running single wall headers(some have been mine), opinions via observation are still valid without personal experience in many situations. As for yours being golden as opposed to blued.....kudos. That is an exception rather than the norm. When building up my 1200 I installed aftermarket headers with single wall construction. I had the carbs tuned to the point the plugs were a nice light tan color and I had no reason to let the bike sit and idle for long periods. I rode it as soon as it was possible. In the end, I painted the pipes black due to discoloration. However, I do agree with the statement re. OEM pipes for the reason(s) stated. |
