two dealers deny the oil sumping issue causing the gutlessness at highway speeds
and claim it won't show on the dyno and my dyno specs are correct.

But then two other dealers claim just the opposite.

so after the bike is out of the shop and if it does not run right and after they re- dyno it and
if the figures don't come up going to take it to another dealer.

He asked why am I willing to pay for the dyno and diagnostic time if the bike is still under warranty.
without going into details told him two other dealers have claimed it is running as good as it ever will at this altitude with the performance items on it and they REFUSE to test it for sumping, keep blaming the mufflers.
He said it's under warranty and that he will do the dyno and diagnostics under warranty
at no charge. He also says it sounds like its sumping.
He is less than 50 miles from the other two dealers.
so for now it's a waiting game. another couple weeks or so.

 

Ok, what is sumping?

Bob

 

huh??? Sumping??

what a minute, i figured it out!! the dealer isn't speaking the queen's english, he's speaking the king's (you know, Elvis)

What he is really saying is there is "something" bad wrong, not a bad "sumping"??

 

Basically Oil sumping is when the oil pump mounting o'ring fails and lets the
oil pump dump more oil into the engine than what it can scavenge
back out. This excess oil causes the reciprocating and rotating parts
to work harder turning through this oil, thus robbing the engine of power.
Kind of like the difference between you running on a hard pavement versus
trying to run waist deep in water.

 

I try very hard not to run at all. lol As my manly gurth will attest to. But at 350lbs, I could be two men. lol

 

What altitude are you at?? I have never heard of sumping b4...but sumping gotta be wrong...hehehe! Remi

 

confusion rules???? Rules who? With all the back and forth you have talked about for months with this sumping idea, If you are as sure as you think you are why not just replace the dang oil pump and O rings ? Seems a lot less investment than all this dealer to dealer hoping and dyno testing.

 

I believe all you have to do is pull the crankcase drain plug to find out if the engine is sumping.

While not as common as it was in the older EVO, sumping can occur in the Twin Cam will the newer style oil pump. But any competent mechanic can usually spot it in a short time.

 

Because the SOB is still under warranty and unlike some fools here I am NOT going to spend my time and money fixing what I believe is a warranty issue.
HD won't re-imburse me for the parts or time.
And if some of you lazy ******* that have problems that may be warranty connected would start making official complaints to HDMOCO we all might get our respective problem corrected.
But if all you do is sit in here and whine to each other nothing will happen.
Numerous times I have given you all the name of the consumer affairs executive administrator
and address and phone number.
Lets' see a show of hands who all have contacted her with your complaints and a cross reference list of others with the same complaint!!

 

you're correct and apparently there are no competent mechanics at Sun HD in Thornton, Co
or at Thundermountain HD in Loveland, Co.
I left three voice mails (polite ones)with Todd and Shelly Erdmann Owners of Thundermountain
About the lack of competency and the fact the service department refuses to at least check out the possibility. Haven't got a call yet. Guess they don't much care either.
