DOG DOWN

[EJ]

Well when we rode up to chimney rock all was fine and good until the second day. We rode all day through rain and winding roads until wham alam bada bam. Drivetrain noise, sucking back through the carb and everything else. I cut the bike off check the oil and everything else and all checks out. So I crank it up and it runs fine so what the hell we ride a couple of hundred miles and then head home the next day. The bike makes it all the way home and I stop to get gas and more valvetrain noise. So I take it the the local shop and guess what the wham blam alam was the roller lifters and brgs. locking up and wearing the lobe off the cam shaft. I just cant believe that it got me home after a couple of hundred miles of screwing up. Well the only good thing is I will get a new cam maybe a .600 or so. Maybe it will all work out...

good to hear she stayed together for you and it will work out. did they say whether or not the rain possibly had anything to do with the failure.

 

[EJ]

I dont know but I wouldnt think so.

 

[EJ]

Alright guys I am wondering about something. I told the man working on my bike that i wanted a .600 cam in my bike and he told me that it already had one I didnt think that stock motors came with that cam in it. I didnt know if the motor had been modified or what.

 

[bdmridgeback]

Correct, Most of the bikes up to 2004 had the .600 in them.

 

[EJ]

I dont know much about this but he also told me that the next size was a .631 or so and was used for the strip.

 

[chacha]

Have the .600 in mine as stock...I don't see a need to change it....

 

[EJ]

Im not going to change it just didnt know that they came with a .600 in it. The guy charged me $727 for the cam, roller lifters, gaskets, oil and labor that seems like a pretty reasonable deal to me.

I think alot of Big Dog owners THINK they have 600. They only way to know for sure is pull it out and look at it or ask and see if they know at BDM or S&S. For 2002, S&S said that the standard cam was a 520, and that some at the end of the model year had 600 when they ran out of 520. Mine is being pulled this week and I will see what was really in their. I know this my bike DOESNT run like it has a 600, so I am guessing I have a 520.

I had an april production date 04 model with a 117 in it and big dog swore up and down that my motor was a non epa motor with the 600 cam. Well it turns out it had the taller cylinders in it and a 547 cam. So I trust no one with these claims.

 

[EJ]

Well I got my bike back out of the shop Fri. and with the new cam and other adjustments that he made it is running like a new bike. My old mechanic said that my bike would cough, spit, idle rough and what not but this new guy adjusted it to where it runs good and it seems like a new bike now. It will cough every once in a while he recommended that I put a Mikuni carb on it and that would fix all of the sputtering what do you guys think about it.

 

[lee]

is it coughing through the carb? what carb do you have on it now? If it's an S&S it shouldn't be coughing if it is set up right - you might want to go up one jet size. Mikuni carbs are good though.

Well, pull the cam the other day to put in the new 600, and low and behold, I already had a 600 cam!!!!
