1996 Polaris Hurricane (Help Please)

[klze]

Hello everyone,
I'm new to this forum but not to the sport!

Been reading around the forum as other people trying to fix there problem,
now i guess is my turn.

Have a 96 Hurricane in mint cosmetic condition i would say,
bought at 45 hours now has close to 100 hours.

was working fine, till the end of last summer, when my drain plug broke and the cane was sitting full of water for about under an hour till I figured out what happened.

offcourse I took action right away, with a help of a friend, we turned it over to the side, got all the water out of the hull, than i cranked and cranked without plugs till no more water was coming out, but still no start
so i put foging oil in the cylinders and in the carbs just in case till i get home.

now once i got home, it still didnt want to srart, after playing for an hour
it finally fired up.
this was the end of the season so i did my regular winterizing and that was it for that summer.

now here is the problem,
I got it all out and ready for this season, checked all the fluids and was ready to go, but no srart !!

battery is full !
carbs and engine are getting fuel
constant and healthy spark when grounded
engine turns over without any noises

so i tried the old school way,
i was holding the plugs close to the whole but didnt screw them in
this way once you turn over everything gets burned in the cylinder as compression rises and combustion occurs

thats where i found the problem, the cylinder that is on the stator side didnt even bather to fire once !
so i put my fingers in the spark plug whole and this cylinder is not making any compression, maybe 10-20 psi I could hold it down with my finger no problem! compared to the other one where i could hardly keep my finger on the whole.

I didnt even bather to grab my compression tester and started to take everything apart, will take pictures today as i go !

It would be really nice of you guys to provide me with some tips
and guide me thru this procedure for cheap and reliable fix!!

thank you all for your time....

Welcome to the Hulk!

So you ARE getting spark on both cylinders, but no compression on the MAG cylinder.

Once you got it to fire at home after the sinking, did you actually ever ride it again, or just ran it for a moment, then winterized it?

Are you going to pull the motor out, or just do a top end job in the hull?

Are you going to re-do the 'good' cylinder at the same time, to ensure the engine runs with evenly balanced power?

You need to be very sure there is no rust in the crankshaft & bearings.

Has your Hurricane had any updates/upgrades?

Hello from Canada to K447
and thanks for your reply.


Yes I have spark on both cylinders but NO compression on MAG cylinder


Once I got it to fire at home I did not ride it in the water, only winterized with fogging oil and disconnected the battery, I didnt run the engine for more than 10-15 seconds because i didnt connect a water hose !


I dont wish to pull the engine out of the hull, first of all dont have all the tools right now, and that would take abit more time than i have on my hands.


doing the second cylinder for even balanced power would be just perfect,
all depends how bad it is once i open it up and the cost of parts


I understand what you mean, but how can i be %100 sure that there is no rust in the crankshaft & bearings without taking the crankcase apart ???

My Hurricane is bone stock ! NO MODS as far as i know!

thanks...

When you pull the cylinders, you will be able to see if the crank is rusty.

You probably should check the crank index, since you had water inside the engine, and if it was cranked with water in there while the spark plugs were still installed, it could have twisted the crank shaft.

I have never seen a Hurricane in person. Where in Toronto are you?

A Hurricane and Yamaha GP1300R - interesting mix!
How long have you had them?

Some Hurricane owners on here have done interesting things, like extending the ride plate.

I'm just finishing up taking everything apart right now
taking pictures for you guys to see, MAG cylinder is gone 100%
its all black with a whole on top thru the ring i think and the head is scarred.

will look at as much things as possible wihtout taking the engine out,
but will need your help if possible please.

I'm around Yorkdale mall area if you know where that is,
have had the cane for almost 3 years now and the GP1300R for about 1 1/2 years. so my friend was using the cane since.

whats the correct procedure to check crank index ??
thank you!

also cant seem to get the exhaust manifold out, the exhaust pipe came out ok, but this gaskets are just molded into the metal already as I assume this is the first time its coming of in its life time and plus all that high temperature from the exhaust port!

so how do you guys take it out anyways ??

[klze]

downloading pictures from the camera today to share with you guys aswell to help me out during the process.

the manifold is out finally, just had to wiggle it around abit.

working on taking of the cylinders now, dont have a small wrench or something to get the 4 bolts on the exhaust side!
