Need some help with my 88....

[Red Warrior]

Hey guys. I'm new to this site, great info on here....
Here's my problem, hoping someone can help.
I have an 88 Warrior (owned since new) that I just finished rebuilding afer it went on fire.
It sat for probably 6 or 7 years and I squirted some oil in the cylinder and gave it some pulls while it sat.
I replaced all of the wiring, carb, cables, plastic, etc. gave it a good sand blasting on all of the burnt frame parts and a quick paint job.
I got everything together but had no battery at the time so I figured I'd give it a shot starting it.
I pulled it about 7 or 8 times and it started right up. It ran for about 15 minutes then I turned it off and was never able to get it started again. After a few more days I hooked it up to my car to give it another shot but NG it wouldn't kick over. Took the plug out and put it up to the cylinder and it seemed to be getting a decent spark.
I had the carb apart before I installed it and it looked really clean inside. I didn't rebuild it but I made sure all of the passageways were clear by shooting some air though them. I picked up a carb rebuild kit so I plan on doing that.
I also tried cleaning the tank out, replaced the petcock and added Sea Foam in the tank and replaced the spark plug.
Everytime I crank it over I do notice gases coming from the crank case breather hose. Don't rememebr that happening in the past.
I got the wire harness off of ebay and seemed to be in pretty good shape. I'm using my original stator and pickups but I had to splice them into the harness. I checked most of wires and they all seemed to match up and tested good. Does it matter which wire is which for the 3 white stator wires? If so how do you know which one is which since they are all white? Where do you test the stator and pickups at and what should the specs be?
I'll include some pics soon.
Any help would be much appreciated...... thanks

heres a link to a free manual download that has the specs and what to test:
ill almost bet stator but you can also all grounds, especially check all the conections for the grounds. the spark on these can be kinda decieving, where it looks good but is actually to weak. i know i can vouch for that and i think a few other guys had that problem.

Thanks 98. I'm going to start with the carb and the stator. Do you know if the 3 white stator wires are interchangable? Like I mentioned I had to splice them in so I really wasn't sure which ones were which. But it was running for a bit.

Did it smoke when it ran?

 

[Red Warrior]

No not that I can tell. Seemed to run pretty good.

 

[henry03250]

Definitely make sure you did not splice the pick up wire in backwards, because it will not run at all and it will try to kick the motor backward when it does fire.

 

[henry03250]

Did you paint the plastics or buy new?

 

[Red Warrior]

It was definitely running for about 15minutes. I just wasn't sure about the 3 white stator wires being correct.
I couldn't believe it started and ran with no battery after about 7 or 8 pulls and sitting for about 7 or 8 years!!! Really sucks that I can't get it started again.

looks like the white wires dont matter looking at the wiring diagram. have you ohmed out the other wires that come out of the stator. the colors and what they should ohm is in the manual i linked to, they are around page 290 some where.

 

[Red Warrior]

Bought red plastics from ebay. Looks pretty cool all red.

 

[Red Warrior]

I haven't ohm-ed that stator wires yet. Hope to do that next. thx

Seems to be the ignition coil. I get about 1.1 to 1.2 on the primary (ground ring to orange wire) and I'm not getting anything on the secondary (ground ring to spark plug wire). Yet I was still getting some spark, maybe its to weak? Has anyone seen this with their coil, getting nothing on the secondary and some spark???
Stator seems to check out ok. They give you values at a specific temperature, mine seem to be close. I have the shop manual from 88 and the coil values are different than the version I downloaded from here. Not sure what's up wit dat.....

Source coil - 270 to 330, I'm getting 266.
Pickup coil - 171 to 209, I'm getting 183

 

[Red Warrior]

OK I'm still baffled. I replaced the coil with one from RMStator. Spark looks real nice now. It's cranking over but not even kicking once.
Maybe I should try push starting it, I saw some guys on here posting that theirs started from a push start but not from the electric starter? That would point to the stator or one of the coils. The coils seemed to test ok though.
Think I'll try rebuilding the carb next, may it's plugged up or the float is hung up.
Any ideas anyone????? thx

 

[87warrior917]

hmmm try to push start it and see what happens... i think i have an 88 stator id sell ya... ill check it to make sure its good if ur interested

 

[1998yamahawarrior]

ill think here, but why dont you try pop starting it and see what happens. let me know and we'll go from there.

 

[Red Warrior]

Thanks I'm gonna try that next.

Are you fuel is in the carb? The float needle could be stopped up and not letting the bowl fill up, if it does fill up is it letting it pick fuel up to get it into the cylinder?

I don't think it would be electrical if its getting a good spark. By chance did you smell your oil to see if it had gas in it. Could be after sitting that long rings could have been rusted or seized just a little, ran great for a bit then one of the rings is broke or cracked and it doesn't have the compression to get it to run. Just a thought

 

[Red Warrior]

I did plan on taking the carb off this weekend to give it a rebuild and check the float. I was also going to try to shoot some starting fluid in there to see if it kicks over.
Thanks, guess I should double check compression also, seems like it's got good compression as it's still pretty hard to pull start without flipping the lever. Think I know where I can borrow a guage from.
Thanks.....

 

[Red Warrior]

I tried starting fluid, same thing, cranks and cranks but doesn't even try to start.
I'm wondering if it could be the rings or maybe a valve is stuck? I'm gonna have to get a compression gauge it check that.
While cranking it over I notice a lot of exhaust coming from the crank case breather hose. Has anyone seen that before? How can I check that a valve is not hung up?

 

[dirtrider73068]

You could take the valve covers off and look to see if valve spring is stuck compressed down or now. If there is alot of exhaust coming from that hose it could be something wrong there should be some its normal, but shouldn't be alot. The next thing would be a compression test just to make sure.
