Fouling plugs and stalling out

[xd45c]

Alright here goes...I went riding for a while today and changed out the plug before I went. Rode probably 1/4 of the time on rocky trails and the rest of the time the throttle was down pretty hard. But when I am going slow and try climbing over a log or something like that in first my Blaster will stall out on me.

When I changed the plug before the ride it was a shiny-ish black. Usually it's dark black though when I change it. Is this a product of riding on rocky trails for a little while, or should I start looking elsewhere for a solution.

It hasn't had a rebuild in a long time as far as I know but still starts on first kick with some throttle. Rebuild the solution to my plugs fouling out so quickly? I'm not sure what jets it's running, but I plan on taking it apart and finding out. Also I've been running sh*ttier oil in the premix at 32:1, but I found some Amsoil Dominator that I'll run after this tank. sh*tty oil also probably leading to the fouling I would imagine?

Here are the specs from when I bought it last year:
Wiseco Piston
Hotrods Crankshaft
Fmf Fatty Chamber
Fmf Powercore 2 Silencer
V-Force 2 reeds

I know that's a lot of questions but help me out I:I

Thanks.

Sounds like you are running rich by the color of your plugs...

They should be a brownish cardboard/coffee color.

Do you know what jets you are running?

also the crap oil will cause faster fouling, im running a lrd pipe, no lid, k&n filter, 32:1 with klotz techniplate, 300 main, ran alll day on a plug that already had prob, 5 hours on it to start with, and no even so much as a hickup

I'm not sure what jets are in there. It's my first quad so I'm learning as I go, I'll have to look around online for some help on how to get to them/change them out. Any idea of a general jet to be running with my pipe?

4cfed, were you open throttle all day when you were riding or did you do some putting around? I was running really cheap oil in the mix so hopefully the Amsoil will help me out. Thanks for the replies.

sounds like u need to change jets might have been setup for winter for more fuel..

You need to keep it revved while "Putting" or its going to foul out no matter what,atleast clear it every once in a while.

 

[brandoz28]

yup...good oil will help, and get that thing opened up sometimes to keep it from loading up

 

[blastermaster01]

Find out what jets you got in it sounds like its jetted rich

 

[xd45c]

I always rev it up whenever I get the chance, and last time I rode I was wide open throttle a good amount of the time. Hopefully I'll get the chance sometime this week to find out about the jets.

We mean while you are putting around to clean it out. Meaning hold the clutch in and pin the throttle till it stops sputtering.

As for learning about the jetts and jetting try using the search function at the top of the page or if you have any questions just ask. We are happy to help...I:I

putt?? whats butting? im on the pipe or idle lol... i ride hard, but i do put now and then, but i normally chop the throttle when im putting, ( wack throttle open well puttin along)...

2 strokes dont like loading up, always ride in a lower gear wehn going slow, ( so the rpms are higher) that helps keep it cleaned out

Yeah that's what I was referring to. And anytime going down hill the clutch is in and I'm on the throttle.

 

[brandoz28]

leave the putting to the 4 pokes

 

[4cfed]

not me ill ride out 2nd or 3rd down hill... . i need a go pro so ppl can see how i ride

I have a tendency to put around quite a bit some times, specailly going through fields from track to track and haven't had any problems with it fouling plugs, or spuddering.

Ok update. Just checked the main jet and it's a 280, my pipe info is in the first post, should I be at a 280 for the main or drop down a bit? Also the idle screw (jet?) next to the choke was at 1 and 1/2 turns. I turned it out to a total of two turns out and my quad started idleing instead of dieing out like it was before I turned it. Any ideas on the main jet and screw positioning? Thanks

 

[UniRacing]

what color are your plugs now when you chop them?

May go down 1-2 sizes and see the difference,or maybie 1-2 higher if your plug is grayish/white.

Keep the air mixture screw 1-1/2 out. needle clip in middle position

Whenever I change my plugs they are black/soot. I haven't done a plug chop, don't really have a straight away to do one. I guess I can go ripping down a couple side streets and give it a shot.

Anybody with similar pipe setup have any input on what jets you are running?

 

[chevyayers]

Is it standard that the idle screw is 1-1/2 turn and the needle should be in the center clip? I have a stock bike. Thanks

 

[xJust_Causex]

yes, start you idle screw 1.5 turns from bottom then adjust accordingly, but that should be close
