Any advice would be much appreciating in helping me diagnose the following problem:
(1) Bike Details - 2009 Busa with Bazzaz and Yoshi R-55 exhaust - PAIR values disabled but present - bike has clean map pulling around 160 HP at the rear wheel on Dyno - bike burns no apparent oil, based on oil level check approximately once every two weeks
(2) Frequency of Event - roughly once every three (3) months - problem occurs on startup after bike parked for several days - parked at approx 65-80 degrees F on sidestand.
(3) Details of Event - bike starts with some hesitation and idles very roughly - feels like running on two or three cyclers - strong smell of oil coming from the pipe. After about 30 seconds engine is barely running - white smoke begins to issue from pipe as bike warms up. Must keep jogging throttle to keep RPM above normal idle at 1200. After roughly two minutes of assisted idling there is no improvement in running condition. After no idling improvement start bike rolling - very, very heavy white smoke issuing from pipe with very strong smell of oil. After 1/4 mile at about 15-20 MPH bike is barely running with extreme amount of smoke issuing from bike. After 1/2 mile at about 15-20 MPH condition begins to clear and all cylinders appear to be firing. After 1.5 miles bike is running perfectly but still smells like oil is burning. Park bike after 7 miles and leave during work day. 8 hours later bike starts perfectly with no noticeable problem - no noticeable degradation in performance. Problem does not re-occur for months.
(4) more details - during earlier occurrence of problem bike was immediately driven to Suzuki shop (in Honolulu, HI) - bike was running fine by the time bike made it to shop. Mechanics pulled plugs and they (purportedly) looked clean - bike reportedly dyno's with no problems and good mapping.
(5) theories - 2 theories: First, one of the value seals is leaking (bad seal or irregular valve stem) causing oil from head to leak into cyclinder whenever that valve (probably exhaust value) is open on shutdown. Second, leaking head gasket causing oil to leak into two adjacent cylinders.
Any ideas or advice would be much appreciated. I am concerned that this episode could lead to serious engine damage if it continues. How can I verify that the problem is with valve or gasket or something else.
Thanks for any advice.
