hi JPX , thanks for your info. just to let you know about my ski, its an 98 xp ltd, purchased for £2200, itook out a loan , so had no money left for magor repairs, i had ski inspected before i purchased cost £40, all seemed ok compression down a litlte 120 same on both cylinders and was told to expect that. i had ski for about 5 weeks probably put 15-20 hours on her then what i would call the rear cylinder small end bearing broke up and ski stopped running. my dad removed engine from ski due to costs this is how we found out what the damage was. the head was quite battered from i can only presume the needle rollers being squashed against it the top of the piston also damaged , it looked as if the conrod was slightly bent, but the crank was still free the other piston was ok, so that is why we decided to go for a complete engine re-build by a company who stated they would remove and collect engine (this i had already removed), within one week return and re-fit and test all for £900. so i borrowed some more money paid a £500 depost waited 6 weeks ended up taking my ski to them and collecting it 4 hour return journey each time, and the ski was still not working, because of the ammount of lies i was told by them i am not sure if the crank was replaced or both pistons done, maybe they just replaced the one damaged piston . do you think the head needed skimming or replacing , sorry this is a essay
yours bones
