Exclamation 1991 Polaris 650 indy RXL triple .. NEED HELP!!

okay, so i have NOT a clue whats going on, but i have gas, i have spark, but no kick or anything.. it hasn't run since last year, but i've had problems with it back firing and kicking before, which makes me wonder if it's the timing, but another thing now, is i have no clue how to adjust the timing on this. Can anyone help? thanks.

are you sure its not the carbs it sounds like carb problem to me have you tried to turn gas off some how try pulling it a cpl times let it sit and dry up then take a lil bit of gas and drop in the cylinders trying not to flood them is the whole reason of turning gas off then pull and see if you get it to wanna run that way and completly eliminate the carbs off you check list if its got spark and your buddy is real sure of it after holding the plug while you pulled then move to timing if your hell bent on it being timing get a manual to what the specs should be then get a timing light and go from there manual will tell you how to set it even if the book cost $200 its better then paying $1000 to have some shop do it

1991 should not be points it should be electronic ignition and if it was not messed with i doubt its a timing issue i would also say carburation have you thouroughly cleaned the carbs and synced them

No i haven't ... there used to be problems with a coil, but i managed to fix that, so i don't know if that could affect the timing at all, but i'm going to try shutting the fuel off, and dropping gas in the cylinder.. but the weird this is if it was getting gas, shouldn't it have at least kicked?

If its a rxl isnt it fuel injection? I got a 91 RXl and thats what mine is. Maybe I don't know what im talking about but had to ask.

All RXL's are fuel injected. It's possible that somebody converted it to carbs, though, but pretty unlikely.

Well then it's either an Indy 650 with an RXL hood or someone converted it to carbs. Anyway, sounds like a fuel delivery problem. Timing usually isn't messed with on older sleds like this.

It's definitely an RXL, the VIN number and everything matches, but nothing i do works, i have let all 3 cylinders dry, i've got new plugs and heated them up before i put them in, and also gave each cylinder a snort of ether and not even a kick, i've checked the carbs and everything, i have a gun somewhere to check the timing, but thats all i can think of, it couldn't be CDI or electrical, because i'm getting good spark?

How did you check the compression? What do you consider good?

This may sound silly, but are you sure you have the plugs hooked up to the right wires? That's pretty much the only way your timing could be off.

Everything is good, i checked it by taking one plug out and putting my hand over the open cylinder, and having someone else pull it... and i did that to each cylinder.. and yes all the wires are connected to the right plug

Can you find someone with a compression gauge? I picked one up at harbor freight for less than $10.

Just because you can feel that it has some compression doesn't mean that it has enough. 90 PSI feels alot like 110 PSI, but 90 probably isn't enough to ignite your fuel.
