[QUOTE="joshbot007, post: 1429510, member: 124095"] Ok so i bought a 1998 ktm 300 exc 2 months ago. And just recently to note it has been getting colder out. So after idoling for 2 mins the silencer gets a nice spooge line down it.(i know letting it idol is bad) it is takem for a nice run a few days later and there is lots more spooging out the back. Also this bike smokes alot. A litte less when it warms up. Also till it warms up the pipe spooges and leaks exaust at the cylinder head where it meets the expantion chamber. I am running 53:1 for reference. So after that ride i was like what exactly can this be. So after some research i was horidued to find that it could be a crank seal. The bike can idol real low and runs very smoothly when reved. Just a little boggy when slowing down using engin break. Did not foul a plug yet of the total hour it has been ridden sence i had it due to this issue. Smoke smells like two strokw smoke that i noticed.good to note that the previous owner only used the bike 6 hours(he was the second owner) never rejeted but added a aftermarket pipe. I can not do a run and oil drain test to compare quanites because there is a leake in the clutch cover now that leaks and that would defeat the purpose. No strange noises or feelings. As this is the first 2 stroke i ever owned. I will try to post a pic of the forst 2 minuet idol of spooge as that is the only picture i have. I have not checked the plug or other things yet. I am realy hoping this is just a case of the bike running rich. Like i said can idol real low and stay there. Starts on first kick as well. Please any thoughts are more than welcome and greatly apriciated! The smoke is mostly all blue excepr for a small puff of white after i blip the throttle. Also does only smell like 2 strokr from what i can tell. I changed the silencer to a core 2 with fresher packing and it still drulles on the silencer when idoling and bliping the throttle alot. (Trying to simulate a ride. I know it is bad but i can not ride it due to ollocation) [/QUOTE]
