timing

Hello, I’m trying to figure out what is the proper procedure is for magneto timing on a Rotax 717. I just got a rebuild from SBT and it’s going in a 97 sportster. I cannot find any timing marks on the stator. Also, I was wondering where the pistons need to be, if it needs to be at TDC, or...

Hello, I just replaced my 2004 RXP 215HP with a 2011 260 Horsepower engine, I received the engine with the crank and the cam gears already in place, stated in description of eBay that it was a good running engine, I reused my old flywheel (used new flywheel bolts) and reused the back cover, now...

I’m working on a 787 motor and I’m trying to figure out whether or not I need or how to repair/replace the flywheel key. Its worn down a good amount but still protruding. Does it come out and if so is there a way to do that? There is still enough protruding that it catches the notch in the...

Installed a new bendix in 2003 RXDI 941and all went well until starting. Turns over perfect has spark and fuel, would just pop intermittently. Sounds like timing. Took back apart to check flywheel key, all good and everything thing else appears good. Put it back together still same issue. Any...

:chillpill: So I have Sea Doo Problems... I own 3, 2 run awesome (717's) but I also have this 2000 ME DI GTX. But this GTX DI has been a royal PITA but I like it and want it to run again. So in 2014 she took on some water and I had to change the stator. Keep in mind that it ran just fine...

According to specs manual timing marks should be at 149 and 65. When i install at 149 the other side is bout 10 degree off. It lines up at bottom of valve opening at about 55 degree. Seems like 130/65 works better but this is definitly a 657x engine. Is there something i am doing wrong. Ive...

Hi, I really need your advice please. I am in the process of rebuilding my motor after a supercharger break. I had to open the engine base to clean out everything. I removed the head, and i did not make any change to the components ( cam or valve..etc ) Now i am putting everything back in place...

Does anyone know what the function of the yellowish round plastic part is that seems to be attached to the camshaft sprocket? My '07 215 wake quit running, lost compression on all three cylinders (35 psi each) and BUDS showed a cam position fault. When valve cover was removed, found the...

Recently got a 1996 sea doo spi project. Had not been in water for couple years, replaced mpem as it was blown. Rebuilt carb. Started in shop for about 5 seconds with slight rev-up on three different occasions. Took it to water and had to choke it started and died couple times. Dd get it to...

Hi everyone, My supercharger gear broken. I had to move the motor Inside ma garage. I removed the PTO cover and found the double gear missing teats. I will change the gear and clean all the oil pump. Now i what to clean the whole engine. I got the 2 sea doo locking tool. I found the TDC of...

Hi All. What's the difference between the single and dual carb 587? Obviously the intake manifold is different, but why is there a different spec for the rotary valve timing? Seems like it should be the same unless there is a difference in the cylinder porting or block machining. I noticed...

I bought a 97 Speedster last summer. Long story short, Starboard side motor runs great, Port side motor misfires back into the carb. Carbs were professionally cleaned, new fuel, plugs, etc, I even switched the carb and ignition coil from the Starboard side to the Port side and it still...
