1999 X1 Lightning (Carbon Kevlar #208) So I just bought this bike and don't regret it for a minute (see the bugs in my teeth)...except I am having a prob: please see the attached. I have not overfilled the oil and I also have a catch can. Any suggestions?

check primary level. if it is too high, you may have crankseal failure | ||||

Maybe these pics will help since my previous attachments were difficult to open...   | ||||

+1 on what Fasted said. That is your trans vent tube. Crank seal failure will result in overfilling of the gearcase with engine oil and it goes straight out that hose. Kilroy | ||||

Thanks Fasted and Kilroy. Just getting my feet wet on these bikes so I really appreciate this Forum! | ||||

Its not a difficult fix - do a search here on Badweb for info PS Get a service manual if you don't have one yet Kilroy | ||||

The vent tube on 2000 and up tubers runs up the right side of the frame/tail section ending up just ahead of the tail light. (Message edited by jramsey on March 02, 2011) | ||||

I don't know of any other hoses that terminate below the seat that would have any oil ever come out of them. Checking your primary fluid level will tell you for sure. Kilroy | ||||

Mine did that at 40,000 or so. It was the crank seal just as everyone else here has suggested. Pressurized oil from the engine comes though the crank seal, leading to a tranny that's over full. Don't forget to change out the rear pads when you fix it! | ||||

OIL PUKEAGE can be caused by the motor sprocket oil seal gone bad allowing the engine oil to drain into the transmission or over filling the transmission and out the transmission breather hose ... Over filling the oil tank which will puke out the OEM head breathers or in the case of a bad engine oil seal into the transmission and out the transmission breather hose, plus you get weeping base gaskets or any where else the oil can get out ... | ||||

Just to be 100% sure its the transmission breather hose I suggest you follow the hose/tube to see if it starts out from the side of the case right above the starter. Like James said, in stock form the tube is routed on the opposite side and under the tail. It could be one of the oil lines between the oil tank and the motor...Just a thought. | ||||

For "SAFETY" the transmission breather hose should be run to a catch container !!! OIL TANK CAPACITY Class 101 and TRANSMISSION FLUID LEVEL Class 101 available on request, just PM me ... | ||||

Transmission vent on a '99 doesn't vent back by the tail light. Your leak IS your transmission vent. Put in a new crankshaft seal and all will be well. | ||||

yep thats the vent hose. also over washing the bike and spraying water in the hose will cause problems too(eventually) but most likely the crank seal. to test it i put some oil dye in the engine oil then looked and found it ended up in my primary fluid. | ||||

"'99 doesn't vent back by the tail light." I stand corrected, earlier post edited. | ||||

"'99 doesn't vent back by the tail light...I stand corrected" Ditto. | ||||

I have a similar problem on my 2001 X1. I tested my crankseal using the oil dye method and it's ok (no colour change in the transmission oil). My transmission oil level is correct and hasn't been over filled. The amount of oil coming out is not that much and only really happens after long highway speed type riding but I don't want it getting anywhere near my rear tyre. The transmission vent tube's standard route goes under the battery then up the right hand side of the rear subframe. My hose only goes halfway up the subframe. The problem with this 'routing' is that there is a significant low point as the hose goes under the battery and therefore the oil that goes up the tube as part of the oil mist cannot drain back into the transmission, it sits in the low point of the hose line. The hose is therefore blocked and no longer vents. Then next time the transmission vents the oil is blown out and you get it over your rear guard. Ideally the hose should be routed so there is no low point, but that's hard to do due to the position of the battery. At the moment I've put on a gear box catchcan/breather to stop the oil getting on the rear tyre but I now need to think of better route to eliminate the low point and fix the problem. Any suggestions on a revised transmission vent hose route would be appreciated. HD put out a service bulletin M-1103 REVISED TRANSMISSION VENT HOSE ROUTING FOR 2000 MODEL SPORTSTERS. This was the fix for this exact problem on the sportster. | ||||

+1 Ausx1er Water in your tranny fluid will exacerbate this issue. If you've ever washed your bike with the seat off, you may have shot some water down the vent tube. When the tranny gets good and hot, the steam carries oil out with it. | ||||

All, It was my crank seal. I took it to a dealer and had them replace it...I read the posts on problems with seating the new seal and the special tool needed...didn't have the time to futz with it since I ride to work everyday. I did download the tool specs from this forum and will likely have one machined for future. While the dealer was in there I had them change the stator and chain tensioner. They only charged me for parts which was a big cost savings on labor. I really appreciate everyone's input. | ||||

Sounds like a great outcome! | ||||

If I "overfill" the engine oil and I get the same "spewage" from my primary vent hose. Will the problem be solved by getting the oil level correct, and getting the tranny fluid level correct? Or is it once oil pushes through that crankshaft oil seal, it MUST be replaced? Thanks! | ||||
| Psyclown |
Its gotta be replaced unless you like filling up your bike with oil all the time and don't mind spewing oil near your rear tire. | ||||
| Fahren |
All a good reason to run the same oil in both holes, by the way, so you are just spewing 20w50 engine oil into 20w50 primary oil, in case of a failed seal. | ||||

Squidravioli: You have a lot of mail !!! | ||||
| Squidravioli |
Buellistic: I appreciate it! | ||||
| Squidravioli |
Do I need to drain all of the engine oil out in order to remove and replace the crankseal? Thanks |
