How bout 2 951's?
I recently acquired 2 skis with the 951's so I am sure that I will become a regular in this forum, yeehaa. I need to run both stories trough you folks in case I am missing something.
99 GSX limited with 115 hours, all original except for new fuel lines. The battery was not being charged. I replaced a faulty stator that was taken out by the metal chips from the starter bendix. I also installed a new external voltage regulator. I blocked off the oil pump and started using the SPX-2 bombardier synthetic oil at 40:1. I also siphoned out the counter balance oil and replaced it with 30W(1.35oz). It runs well. I have not touched the carbs. Needs new fuel sender float and a new beeper. I will drain and fog regularly and use stabil in the gas. I will also check the compression soon, kinda don't want to know until summer is over. I do not sense any cylinder noise, rough idle, sputtering etc. I will refresh the top end before next summer.
98 GTX Limited, blown engine, it was flipped over in the lake and blown shortly afterwards after a "friend" was allowed to ride it. Its been sitting for 10 years ever since. I pulled the engine this week and found the hydro lock damage, the mag side piston literally exploded. The skirt is completely shattered, the small end needle bearings are gone, the reed cage was broken, the head is severely pitted and the rod is bent. The crank is rusted now and I can not get it to turn much. The good news is that the engine cases are intact except for a little damage on the bottom of the intake port where the crank comes close to the case behind the reeds. The mag side cylinder looks like it needs a resleeve but no apparent cracks. The PTO side looks just fine but the crank may be damaged there as well, hard to tell, not that it matters.
For this ski, I have a whole year to work on it but I have a limited toy budget with 4 dirt bikes, a 4 wheeler, and now 2 skis. Needless to say, meticulous maintenance is a very important aspect of my routine. I would like all of your thoughts on how to get this one going again.
- SES will rebuild my crank for $299 (phase 1)
- head/cylinder exchange - top end kit?(phase 2)
- SES full rebuild?
- Fullbore complete rebuild?
- SBT full rebuild (3rd choice)
- replace gray fuel lines
- eliminate oil pump
- rebuild carbs
- check jet pump
My goal is to have the 98 GTX for pulling the tube, giving the younger kids rides, and Dad's backup for the GSX. I wont want anyone playing on this one, reliability is first and foremost.
The GSX will be tortured buy the kids, probably flipped, towed, flooded, raced, etc. I think I need to set a rule that they do not try to start it after it has been flipped and they need to kill it if they hear anything different or feel it sputtering, I know this is asking a bit much from 13 and 15 year old kids.
What is the best way to flush an engine after it has been flipped/flooded?
Is it necessary to connect the garden hose after each lake outing? We start the ski on the trailer on the boat ramp to flush out the lake water, let it idle and give it short revs for about 30-45 seconds. The goal is to get the water out of the crank, should i fog it a little after each lake ride? Will that foul the plugs?
I will try to upload some pics, I have some good ones.
