so i got my ultra and i am trying to bring it back to stock. i think the timing is a hair off. when i put a timing light in the hole for the flywheel, what am i supposed to see? thanks

you should see the timing marks line up. why do you think the timings off, unless someone had it apart and failed to put it back together as taken apart it unusaul for it to change

at one point when i was putting the triple pipes i got for it on i was playing with the timing. then i decided i didnt want to put the pipes on. i beleieve i changed it back, but it seems choppy kinda like a car does with bad timing. i remember lining up the stock timing marks but who knows. just a thought

You need to find out what the original BTDC spec is from the factory and use a dial indicator to set a mark on the fly wheel or clutch in line with another mark on a stationary part of the motor. You then need to rev the motor up to whatever rpm the manufacturer calls for and check the marks with a timing light. It's the only way to be sure if things have been shifted from stock and not marked before the work was done. It may take you a couple of times before you get the marks dead on. Doing a good timing job can be a little time consuming depending on how accurate you want to be. Remember that having timing a little off can destroy a piston very fast.

right. thats kinda what i was hoping that someone knew, i have all the tools to find out the degree, i just need to know what its supposed to be at. on the flywheel there are markings too.

I never trust the flywheel markings until I have checked the timing with the dial first. I have used a section of coat hanger temporarily bolted to the motor and bent right at the clutch then scribed a mark on the clutch to get my two marks. Sharpen the hanger tip and you have two very precise marks to look for. Some people use a marker on the flywheel but that leaves too much room for slop as far as I'm concerned. I used the wire trick when I worked on sea-doo's and had to take the timing off the pto flywheel.

well ive tried that and even got a degree wheel, because u had to time it for triple pipes. but when i put the coat hanger on it was vibrating back and fourth at the rpm SLP told me to set it at.
