Is that rear piston broke or am I that green to v twins?
Are you referring to the short skirt on it? It's the clearance for the front cylinder.


Unless I'm missing something. :D

ray, you should temp bolt the jugs back on to get the deck height. since your gonna have them machined you should have then cut also. proper deck height will give you a more efficient burn. along with slightly more compression to go with your 600 cam. IMO

also most local machine shops are overpriced compared to shops who do this work daily.

contact john sachs. bet its worth the shipping costs to florida.

I'll have that done. Thanks for the suggestion.

Got the final part of the motor apart now. Didn't find anything wrong. Pulled the pistons and lifter blocks and all the lifters look fine. No broken parts. No starting to think whether I heard something wrong or not! :loony:
But I have enough miles on these motors to know when something is not right. Wondering where to look now?
Again I only hear the sound when it got up to over 1500 rpm so lifters still come to mind. Seems anything else like oil pump would make the sound at any rpm.

Here's the latest pictures:











At least I will have a new top end job when it's all said and done. :D

:cheers::cheers:

Ray, after you get the scoot running could you post up the PDF file from TP for those of us with the TP boxes.
Sure will. Will get it printed and scanned and upload it for all of you here that have the TP covers/rockers.

:cheers:

hate to suggest it but check the vent tube in the tank. when mine broke it sounded real bad at certain rpm's.

but like you said, you were due for a rebuild.

Ray, for those of us that hope to get as many miles as you and have to rebuild due to "wearing it out", thanks for the day to day updates. Damn near like we're there handing you the tools. Oh yeah, get some damn 12 pts!!

Well that never crossed my mine even though I replied to the other "rattle" tread suggesting this. My tank is drained so will be easy to check. I'd shit if that was it! :eek:

A top end job is good though. Another break-in period. :lol:

No problem, glad you are following. Now if I could figure out what that noise was. :rant:

Ray Do you still have the valves in the cyl head.I wonder if the guilds are out of spec ( TP Problems) making the valve stem wear wrong slap instead of glide.You said in one picture that the exhaust was leaking into the rocker box area correct. Just fishing:cheers:

Hey chop, yeah I'm sure they are worn. At least the rear exhaust. I haven't pulled the valves yet and really don't intend on. Replacing the heads that Little Boo is sending me off of his 06. Thanks :D
 
Ray just to give you an idea of cost, to have my cylinders honed and .045 milled off the top was $120. Well worth that investment. You could do that and get a 600 cam on ebay for less than a $100 and you would still have a dependable rider.

Hey Ray,

Thank's for sharing the pics for all of us gearheads to see. I've studied them and of course not being there to examine each part makes it hard to pinpoint your marble issue. I for one don't see anything out of the ordinary, you have the normal piston skit wear and of course cylinder wear. Like you said earlier you have a rear exhaust seal/valve issue. I know your replacing you camshaft and of course new lifters are a must on a new cam and with the mileage on you motor. Your motor is clean given the mileage but also because of the oil and filtering system you used and your attention to detail. I was wondering did you pull your K&P filter and check to see if there was any abnormal debri in the filter media? Since your getting donor parts from a 06 model are they the new style heads with the larger valves and S&S rocker arms? Or are you going to reuse your TP rockers and boxes? Like most have I would also recommend the S&S .600 cam to bring your motor back to the way S&S would had built it, especially because of your desire to keep it reliable and it will certainly wake up the motor in the lower and mid-range end.
Keep us posted Ray and I hope you find the marble soon, one
last thought? When you heard the marble sound your weren't shaking you head we're you? :roll::roll::roll:

Have you checked the wrist pin to rod clearance? That will make a knocking sound at a little above idle.

Ray - you probably did this but have you taken a look in your primary to make sure everything is Ok in there?

You guys "ain't" going to believe this!!! :eek::eek::eek:

My vent tube is busted and most likely the culprit to the sound I was hearing. The tube is just laying down on the tunnel inside the tank. I can't frigging believe it. :rant::rant:
I pulled almost a perfectly good motor down for nothing. :angry:

I can't believe this is happening. Thanks MARV (I think!).

I would rather find it and be pissed than to not find it at all.:angry: But you can't beat your timing! How often will you tear your bike down for a rebuild and have most of the major components donated? Good luck getting it all back together. I have the split tank on my '05 Pitbull. Does it have a vent tube like that too? Guess I really never looked for it, but I will now. :cheers:

It will be most likely in the right tank and if you look underneath the tank at the rear you will see it's plugged on non-Kalifornia models. My bike was a Kalifornia model so it has a tube that originally went to a charcoal filter that's now been removed.
