If you had water in the cone, you should replace the seals. Would also check the bearings and replace if any signs of wear. You shouldn’t lose any pressure after 10 minutes. Water in the bearings will lead to a seized pump.

Pulled this out of the back and the box was full of water. Lot of corrosion. I was able to jump the solenoid with a screwdriver and engine turned over. Replaced a few terminals and cleaned the fuses(they had not blown) gonna let it dry out then hook it all back up and see what happens.

Hey all. Rolled the ski out yesterday and started it up. I revved the motor and then it dies. Try to start again and it’s got no power to anything. No gauges no beep no start. I put in a new battery at the end of season and kept a tender on it over winter. Even started it a few times over the...

Hey all. Did a top end rebuild on a 717 back in July. Motor started and I checked compression. Had 150 in both cylinders. I started it again and then heard a screeching noise and immediately cut it off. Motor was very hard to turn by hand. I took the plugs out and tried to start again but made a...

Well after the weekend of the 4th. I'm happy to say that the new engine ran great!! Got a top speed of 53 with one rider.

Finally took the new engine out for a break in today. Warmed it up at idle for 10 min then varied the throttle up to 20% for 30 minutes. Will go back later this week and vary up to 50% then 90% throttle. Got to get it done before the 4th!!

Thanks mask1!! I have no idea on the hours. Paint has held up well. Run rail not so good. Need to do some touch up on the vinyl wrap but that was expected. I'll let y'all know how it runs.

That's what I'm reading too. Too much would not be a bad thing would it

Hey guys! I replaced a 717 engine in my speedster and have a question. I know there is a break in oil to run in 10 gallons of gas in addition to the stock injection system. What is the correct oil ratio????? Don't want to get this wrong as I've got a lot of time and $$ in this project...

Yes it is. surface is raised then drops down to the seal around the cover.

They are more shallow scratches. Nothing deep. Can the surface be honed down? My son works at a machine shop. Only concern is the gouges on either side of one of the holes.

K thanks. Will definitely get the new valve.

Even with the gouges at one of the holes?

Hey guys! Getting ready to install a new SBT 717 engine. I'm concerned about the condition of the rotary valve cover and valve. It doesn't feel like there are deep grooves just light scratches. I am concerned about the gouges on the edge of one of the ports though. Also, is the valve supposed to...
