basically if drains were plugged would it overfill it?
thanks

yes, if the drains were plugged it would overfill to the point of spewing oil at the seams and submerge the seals.

Tony,
Unfortunately I think you will use some oil when you are on the freeway. But once you get to the hill country I do not think you will be using much. I am really hoping that the 30 tooth sprockets will help slow these conversions down and resolve this oil use issue. If it does it is a reasonably priced fix at $60 for a sprocket.

We are then going to take temp readings using a lazer temp gauge and just see how much hotter his bike runs than mine does at various speeds. If nothing else we can see how much difference the conversions affect temps.

Hey, this sounds like a company boon-doggle! A fun-ride supposedly related to "work"!

[QUOTE=cjburr;745538]Gee......I was told the longevity of my bike would be better than stock as all the tolerances would be optimized and better than stock parts were used.
now you guys are saying I can't cruise down the highway at 4000rpm or more without losing inordinate amounts of oil and having excessive engine wear ???
I'm not buying it. 
If this is the case I see no reason for anyone with an 883 to buy a big bore kit and NRHS and all the rest might as well shut their doors to this portion of the Sportster community.

It's no different than the hot-rodder who puts high-compression pistons, high-flow heads, and really stiff cams in his Nova/Mustang/Dart/etc. with an automatic transmission. He suddenly finds out he has to run a high-stall converter to make it driveable and the high-stall converter puts tremendous heat into the tranny fluid, due to the increased converter slippage. So, he adds a cooler to keep it under control on the highway, only to discover he has to go to a larger radiator to keep the modified engine from boiling over, etc. It's all a trade-off.
Plus, why would a person want to run 4,000 rpm on the highway with such a big engine? Even high-rev, big-bore sport bikes don't arrive at the dealer with such an appetite for self-destruction.

Do I ask my riding buddies, Hey can we keep the speed down to 65 mph ?
Yea, they will be laughing at me all the way down there.
I changed my oil and filter to straight 50 W, and I am carrying 2 extra qts.
Did I bring enough oil ?
Also, will have to be constantly checking my oil temps and oil level.
Are we having fun yet ?

Imagine that "fun" the whole way to Alaska from Pennsylvania, 10,000 miles... hence why I'm trying to throw anything at it to "fix" (read band-aid) just to get by. Should have the 30T by the weekend, but probably won't get it on until early next week. I guess I'll have the Jagg oil cooler from NRHS sometime next week (sound right Dan?). Once I install the oil cooler I'll switch to synthetic.
Any thoughts on what grade of synthetic I should use? I want to stick with the Syn3 from Harley simply for my trip to Alaska so I know I can get the same oil along the way if needed.
My buddy that has been helping me out has politely dropped some hints that he's getting tired of me being over there, so I just don't have the time to work on this like some of you guys.

Been there done that, 450hp, 347 stroker, 6 speed Mustang never stopped me from cruising down the highway at all, quite to the contrary, but that's apples and oranges.
My point is I have the oil cooler and the motor is fine except for this oil problem with the seals. Once I put the new seals in and get going again there is no reason I can't have what others here have, a bike that doesn't overheat and can cruise down the highway at 4000rpm. If the gears on the primary side need to be changed so be it, but these bikes shouldn't be regulated to running 4000rpm and lower, if they are what's the point in having one ??
Are oil changes and topping off going to be regulated by how many times you take it to redline, or take a 10 mile high speed cruise ?? I do that every day going to work
If I wanted a bike to cruise around on at those rpm's I would have bought a BT.
This is a crock.....if the Buells can do it then we need to know why so our Sporties can too.
Does Aaron's 100+hp Sportster use oil ?? it's an 04 if I'm correct.

I am glad I have a 93 that just leaks. Anyone feel better yet? I am sure in the end it will be worked out and we will all be bombing down the road.

I realy dont think anyu harley was make to running High RPM's for Very Long I feel this way if I cant bet you in the 1st 1/4 miles why I need to chase you down. Heck if I want a High RPM Bike I would get a Jap Bike But if you want an stump Puller Keep the HD and Smoke they ass from Red light to Red light.

By your logic (and apparently many other 883 converted owners), I should be able to ride my Hayabusa regularly on the highway at two-thirds of factory redline, or somewhere in third gear at about 7,260 rpm. 600cc sportbikes would be running the highways at 10,000 rpm - in either first or second gear. Will they take the abuse? Absolutely. Is it good for them? That's questionable..........

This 4000 rpm limit is a bunch of bunk. This is not a fix, not even a good suggestion. What good is a bike that can't handle high rpms.. I constantly cruise at 85+ Now I don't have a tach (yet) but I can tell I'm revving high......
,,,,,,,,,,hoping that CJ's Bike is great when his new seals are in.
