I would start by pulling the front pump cover and see what you find. If all of the cage is there I would inspect the flywheel with a mirror and flash light through the sc hole as you rotate the motor...

You should change your screen name to "thatdueche596". Lol

Looks awesome!

My .02. Andy bought a used boat and these are the chances we take when buying anything used especially a boat. However with that being said there are obviously some other circumstances here...

Nice work bud. Best looking yami motor Ive seen. Looks like it should be able to take some punishment too.

Right stuff isn't sandable.

Lol.
Who said anything about cutting it apart? I have done several and never had a problem and never had to cut anything. Heat the housing, pop it apart, pull out old thermo, install new thermo,...

Very nice work and great idea to build a simplified harness.
Hey Shrabber.You really should put the bottle down. Your sounding like even more of an ass than usual. You should stop clogging up this...

Good Idea. All the BS does keep alot of people from posting good info.

I thought that was what the whole kawi section was for. LOL

Should also take into consideration how many hrs are on the stock springs. They will loose some tension as they wear. This being said I have spun 8800-8900 with stock springs and ti retainers on...

Where are you located?

Need to get rid of the ceramic washers in the SC before you put any time on it.

Considering the sea doo has an 83mm hub and 158 liner and the riva yamaha pump has a 75mm hub and 160mm liner it would make since that the riva pump would need a lot more water to feed it....

Dirty injector maybe.

Wish they had this for the seimens ecu.

[/QUOTE]

Your going to want to run 60's or 80's depending on ecu and ability to tune. 50's will work in some situations but better off going with larger injectors and lower pressure.

With riva ecu and ET race running 50 lb injectors I had to crank the fuel pressure to over 75lbs at wot in the summer. Much higher than I would have prefered. Could not even run 50's in the cooler...

More like 45000rpm to 30000rpm in a split second. Charger spins at 5.2:1 ratio. :eek:

Still dont work for me. says " video not found or access denied" Stange part is it shows the gps map and shows a still shot of the river and the length of the vid but when I hit play I get the error...

After this imact I don't see how there couldn't be possible crank damage from the motor either flexing backwards due to oem motormounts or pump/driveshaft getting shoved into motor. He said the pump...

Was the reverse bucket broken? If not I cant imagine how the impact could have pushed the shaft into the motor to cause thrust bearing damage. Even if the engine slid back I dont see it being able to...

140 extreme with 9.5:1's has a final comp ratio of roughly 19.8:1 and a Race charger with 8.5:1 has a final comp ratio of roughly 18.5:1. Now assuming both are running adequate IC's to keep things...

Understood and I dont disagree but some of us "rec riders" have race chargers and rude 3's and when it is time for a rebuild adding high comp pistons is not a good idea.

I had a rear bearing let go on one of my chargers at 20 hrs and screwed up alot of shit and I'm fairly certain that that would not have happened with the triple bearing. My next charger was triple...
