Hey so I just bought a 2006 Buell blast. Apparently it sat for 3 years and the guy I bought it from got it running, replaced the fuel, cut the stock exhaust short, rejetted the carbs BUT didn't change the oil. I just rode the bike home then changed the oil today (having looked on youtube at several videos on how to do it). I'd say there was less than a quart in the bike :/ Anyways, I started the bike and let it run a bit to get the new oil churning then checked the oil levels. There was an great amount of pressure when I went to open the oil case. I'm assuming there's a vent somewhere for the crank case but not sure where is it. I've looked at several different threads on different forums and can't figure it out. I'm still new to the motorcycle world in general so any advice would be much appreciated! Also, since the bike sat for 3 years (it only has 3300 miles on it), should I also change the tranny oil? | ||

Check oil - engine just turned off. EZ | ||

Concur. Check (and change) oil only when HOT. The Blast will show zero oil after sitting for a week (or less). It only takes 1.5 qts to do an oil and filter change. Maximum capacity is 2.25 qts. | ||

Change the tranny after you've put a few miles on it. | ||

CRANK CASE VENT TUBE: There are TWO of these ... One on the Rocker Arm cover and One on the rear of the crank case for the transmission ... The TRANSMISSION BREATHER for SAFETY should be ran to a catch container because you do not want to get oil on the rear tire ... The ROCKER ARM BREATHER(HEAD) is ran to the air box and is recommended to be ran to a catch container also because it will fill up the air box and leak out on the engine ... Iam Noone | ||

I did change the oil while the bike was hot and the level on the dipstick while the bike was hot afterwards was fine. And I don't have an air box on the bike yet. They guy put some weird air filter on it that's foam and has a spring in it, but fits into the carbs with a rubber seal. I'll have to check and see if there's a tube or something where the air box should be... Beullistic thanks for the info on location. I feel like there shouldn't be any pressure in the oil tank after running the bike a bit so maybe one of the vents is clogged (or blocked off since I don't have an air box) | ||

This is a TWO stage OIL PUMP ... The RETURN side has more pressure than the feed side as the input pressure aids the FEED side ... That is why the oil CAP is the screw in type and you only check the OIL only when the engine is at operating temperature ... Get a FACTORY SERVICE MANUAL and PARTS BOOK for your MODEL YEAR ...

Thanks Buellistic! I did check the oil at operating temperature which is why I noticed there was a lot of pressure behind the dipstick and why a lot of air escaped while unscrewing it (it started blowing a little oil out with it too) I also looked where the air box should be and found a hose that has a three way hose connector but one of the ends is covered. I'm assuming this is where the PCV valve would go. What happens when you ride the bike with no PCV valve in place? Also I did get a service manual and it does help, however I do like input from other, more experienced Buell owners  I appreciate all the help! | ||

The PCV VALVE is in the ROCKER ARM cover, not on the end of the breather hose at the CARB. and it also should be ran to a catch container, not the carb. air filter ... Iam Noone | ||

I have checked the oil level on my bike at least once a week for the past 14 months. Always checked after a run. I have never noticed any venting of pressure when the dipstick is uncscrewed. | ||

I have a similar issue, mine leaks all around the oil fill. It also leaks/bubbles at the DO NOT REMOVE bracket. I believe for me it’s all my gaskets on the top of the motor causing some leaks, I'm tempted to just rip the whole motor out and go through it all. But yes, the bike holds very little oil and I think that is also part of my problem even after doing a complete oil change, including filter, and only using 1.5 qts it still seems to bubble out of the oil fill. | ||

Pressure at the dipstick usually means oil overfilled or crankcase breather (PCV) blocked or plugged. The extreme cause is oil pump failure, which means you'll keep filling it with oil, until its very overfilled, just to get it to read on the dipstick, because the oil isnt getting pumped out of the engine crankcase. Is the bike completely stock-no modifications whatsoever? I doubt it is if you dont have the original engine. Are you changing the oil when HOT. Draining the engine immediately after shut down? Oil leaking out of many places can indicate someone modified or connected the PCV valve breather hose improperly. Plug the hose or restrict the hose and you will develop leaks everywhere. FWIW:Ripping the engine apart without knowing what the problem is and putting it back together hoping the problem is solved is just like taking the carb apart to "give it a good cleaning" and hoping that fixes the problem: It rarely ends well and rarely fixes the problem  |
