whats the best plugs for a 1991 lt250r?

[jeepman137]

sorry, i dont know if this post is in the right place of the fourm but if it is, just let me know, or can one of the mods move it?

well the guy im getting my LT from said it fouls plugs like crazy, so i am wondering what is the best plugs to get, because i was just gonna go get a case of plugs to keep around.
NGK?
splitfire?
somebody told me that i can get a case of 12 NGK's at a MX shop for like $10, so i was just gonna do that, but i dont know yet...

I run the NGK BR8ES plugs. I have really good luck with them in my 86 LT and I think most people will agree with me that the NGK plugs are about the best plug out there to run in a quad or dirtbike. Sounds to me like you need to check you jetting and you mixture in your gas. Sounds like it is running really rich if you are fouling plugs all the time.

i use a NGK B9ES. I've never tried anything different because that is what came in my quad when i bought it used. I figure if it runs good, why change the plug type? I've owned my 250r since feb 8th and i have NEVER fowled a plug. I almost fowled one when i was breaking the engine back in from the rebuild...but i replaced it and still no problems. Good luck...i'd try your jetting.

yea i know, when i get the quad friday im gonna have someone take a look at the jetting, and im gonna ask him what ratio of gas he was using...

use amsooil dominator at 50:1. if you need some get ahold of pete (primesynthices) or me.

[jeepman137]

well say if this guy is using some other oil at 32:1. will the change to 50:1 and a different oil make a difference? like harm the engine?
also, what gear oil should i use?


EDIT: oh yea, and can you or that other guy ship it to me or something? is it cheaper than if i buy it at a shop?

[suzuki LT250R]

the change in oil wont hurt. 370 and pete will be able to get in delivered to your door for cheaper than you can go to your local shop and buy it. I swithed to a amsoil gear oil in my LT and it made alot of difference. It shifts so much smoother. and at 50:1 you will be running alot less oil.

the best way is to set you up on a prefered buyer program. i'll be setup in a couple weeks. on the prefered buyer program you order your own oil stright from amsoil and you get it a dealer cost. i would say buy a bottle of dominator from pete (prime synthetics)

actually i heard amzoil interceptor waz made specifically for powervales "less build up" then dominator iz this correctjust what my shop told me

Any of you guys ever use splitfire plugs? I am tempted to try em in the R, but just wondered if you guys noticed a large diff. if you've tried em.
