Im about 95% percent sure that my plug is fouled, i have two questions though, when i kick it leaks fuel is that normal? It drips a little. Also i have a ngk R br7es
Can i go to autozone and get a ngk br7es
Idk what the R means...
 
Where is the fuel leak?
Yes you can get a plug at any auto parts store. I get mine at advance auto.
The "r" means "resistor".
You want an NGK B8ES
 
Fuel dripping means a malfunctioning needle and seat either caused buy crap in the seat, worn tip on the needle or an incorrect float level setting.

You need a B8ES plug the 7 is not the correct heat range.

No need for a R series plug unless you listen to the radio whilst riding.

What are your mods, what oil and what ratio do you use?

Do you know your jetting?

If the leak is black spooge coming from the header pipe attached to the jug, you need to seal it as the jetting will be affected.

Blaaster, Have you ever noticed how alike we think??!! Hahaha must be a southern Hemisphere thing.

What he said! Check your float height in your carb. thats usually culprit No. 1 when it comes to fuel leaks.

So basically I should take the carb apart? It only leaks when I kick, and its only happened since the plug got fouled, The top end was done by Yamaha and the whole thing was gone through done to spec 3 motor hours ago. ITs been bored .40 wiseco piston, port and polish, full HMF exhaust, idk about the carb it does say mikuno but idk the "MM" Idk how to check but it is a twist throttle, it has a 360 main jet I do know that. bout all I know And I run a 32:1 ratio with yamalube 2R with 91 4 gallons to 1 pint. it is a black color though. And I can tell its a fouled plug due to I have to take it out clean it, and then it'll start but I have to hold it the throttle open a little to keep it running and it has no power lol.
It didn't ever do this until I took my K&N air filter off and cleaned it, I did put the seat back on to cover the air box though if that's what you mean by seat........ That could cause this? Also what could I use to seal it, it should be sealed as it was just gone through and rebuilt and never leaked before.
 
Contact the stealer if it didn't leak before. Unless you put the 7 in since you got it back, they should have put the correct plug in if they were doing a complete re-build.
I suggest cleaning carb and sealing exhaust yourself so your quad doesn't sit for a week or more at the stealership.

Do they make actual gaskets for the headers or do I use RV to seal it or...?
