Starting problem after mud riding.

[Roccothebeast30]

hey guys,

Yesterday I went for a ride (trail, mud and water hole) after maybe 2 hour of ride, my blaster stop (into a dry trail, had enought time to dry). I tried to kick it back and no start up. I ran it since 2 years without changing spark plug and everything. I had one new with me so tried that out. It won't kick start but started by compression, ran maybe 10 meter and stop again, never start after this. Need to bring it by hand to home grrrr...

When I got home I inspect some point:

- Spark plug was in good shape.
- I had spark into my spark tester so I figure that coil, spark plug, tors system, kill switch are good???
- Spark was moist and smell gaz, so I figured that my carbs is good.
- I had water into my magneto cap, dry it out with compressed air, cleaned it with brake cleaner, having spark but wont start.

Do you having some idea what I need to check?
TORS System can be the cause ??? (i'm having Spark) ???
Kill switch??
Anything else????

Let me know that will be great!
Thanks All....

i have the same problem i went out biking a couple of days ago and it quit out in the trail after a mud hole i had to get my blaster towed home i cheaked it all over and still cant get it started lert me know it you fiind anything

hey,

that's weird because I rode it arount 15min into an open road (dry area) before failure.

So I don't really think the probem comes from water or something like this...

If I'm having a kill switch , magneto, coil, spark plug, TORS system, wiring problem, I'm supposed to have NO spark at all, right?

2 years same plug huh lol
check the compression...get a compression gauge 30 bucks at auto parts store

 

[jus_me]

All grounds good? What color is spark?

 

[98blaster]

I had one of mine do this, it had spark when plug was against head, but once in the cylinder under pressure had no spark, the stator was weak, changed stator, all good now

 

[Roccothebeast30]

Yep ! I confirm, just changed the sources coil on the stator and Works. Source coil was out of specification. Thanks all.

Huhhh YES, if the carbs jetting is right and well adjusted like a BOSS, your spark plug was supposed to run on a nice chocolate color, we are not supposed to change plug every 2 weeks, dumb ass! And I run BR9ECS just saying, It cost more money but react better in high temp and can take more vibration.

compression test LOLLLLLL! funny guy!

With a plug chop the plug insulator should be a biscuit colour, if it is chocolate you are rich.

Unless you are running sophisticated fuel with high compression you waste money on plugs.

The B8es will be just fine.

When you scrape chocolate with your nail it come like pale brun (biscuit) that what I mean.

And it's not a waste of money because It last longer in my case!

thanks

for someone coming on here asking advice...you sure sound RUDE..
if you know everything then why are you asking for help?
we can only guess because your quad is not sitting in front of us!
if it was sitting in front of me then i would have solved the problem already
thanks for your rude comment

Sorry about that, my english is not good as you so maybe i didn't use the right term.

Sorry again

cheers

ok thank you for apologizing
what are the mods done?
why do you need a 9 range plug?
you do know that a ngk 8 is hotter then a ngk 9 right

 

[Blaaster]

If you have to use anything other than a B8es plug, something is amiss with the jetting.

Are you conversant with the smoke ring on the insulator after a plug chop?

Extreme compression and the use of sophisticated fuel to avoid detonation needs a specialised plug.

Even highly modded engines can get away with using the stock recommendation plug.

Mods:

FMF Gold Series Fatty Complete kit.
TASSINARI V-FORCE 4 REEDS
UNI Filter Open in Alu. Cage.
Jetted (don't know the size)
Intake, exaust and head port and polish.
Barnett Clutch kit.
banshee front brake and front YFZ shock.
RAZR back and Kenda Front.
Motion pro TORS eliminator kit still to be install, just receive the idle screw.

It was like this when I bought it last year, run with maybe 40 times, wide open throttle, since last years and still strong

The owners before said that it run it on 9ECS with 98 octane fuel at 40:1 (motul) and I never had problem, I run the same plug since this time, only clean air filter and oil it every 5 run.

Will probably rebuilt and restore it completely for my girlfriend this winter and buy a banshee, will see...
