Picked up a 1996 XP with the 787 motor. Motor was new from SBT last year. Ran great for me 6 or 7 times on the river in the last week or so. Last time out the motor lost power so I stopped and when it idled down it died. Did a compression check and the rear cylinder is 150 and the front cylinder is 30. Motor turns over and there was no metal flakes on the spark plugs, no clunking, rattling, or unusual noises when it turns over either. What could be the possible issue here? Head gasket? Also the rave valve on the rear cylinder (the one with 150psi) is leaking oil and running down the block but it has been doing this for 2 rides now. Thanks in advance for any insight or advice.
