Sup guys/gals. My name is Mark. Just came across this website while I was searching for parts for my quad. I have a 92 LT250R quadracer. It's got some mods. Some are:

P&P jug
Bored 1x over
Rejetted w/ a 30 main jet
boysen pro stock reeds
Stock 12 tooth front/44 tooth rear
Turf Tamers out back
FMF fatty with S11 equalizer silencer

Looking for a FMF power core silencer if anyone is selling one. I checked Ebay and found nothing. Seeya on the boards. -Mark

Hi Mark

Welcome to the site. That is a big rear sprocket you must have a lot of torque. As for the FMF's you should post it down in the classifides.

Hope to see you around

Hi Mark! I am Allie, I am new here too. My husband has a '92 LT250R. I am not sure on all the mods but he does have a FMF Fatty on it and an 11 tooth sprocket on the front, not sure of any more He took the airbox cover off of it last night and insisted that I ride it and I about killed myself!! Anyhow, welcome to the group. They seem like a nice bunch of guys. (they haven't kicked me off yet & I have a 4 stroke)

Thanks. Ya I went big since the kind of riding I do is mainly short tracks and trails. I figured I use more of the lower gears and don't whine out 6th gear too often.

Allie- I took off my air box cover too and it felt like a totally new quad. So needless to say it's staying off!

You should if you haven't already rejet. Taking off the lid is going to make you run lean. Just a heads up. Running lean does make it insanely fast but it will burn up your motor pretty quick

Don't take banshee's suggestion lightly. Either put that lid back on or put bigger jets in. A friend thought he was cool when he put FMF pipes and a K&N filter on his banshee without changing the jets. We all warned him not to do it, but you know how some ppl are. You should've seen how quickly the pipes started changing colors from running so hot. I guarantee once that head comes off he'll see how crispy his pistons are.

I run mine without the lid because of the bigger carbs and jets in mine. It actually "growls" when I hit the throttle because of it sucking in so much air. Check out your spark plugs after riding around pretty hard for awhile. You should see a difference in color and less oil on them from too lean a mixture.

I used to have a 28 jet in there and went to a 30. I also adjust the needle 1 setting to fatten it up. After riding hard for about 10 mins the cylinder wasn't any hotter than it was before I removed the air box cover. But I think I'll maybe put a 31 or 32 main jet to be safe. Thanks for the advice.

if you take the airbox off all together adn just run a clamp on thats a big difference. thats what i have on both of my banshees

Heck I'm skeered enough with the top off let alone that whole thing out in the open. I cross creeks alot to get where I'm goin. Must be nice to have that as an option.

 

[Banshee]

As long as you have an outerwear you should not have any major issues. If you have the airbox and water gets in it then is just holding the water for the filter to suck up. I am going to move to an bolt on air filter soon. I go through quite a bit of water and creeks. To each his own though

I told him last night and he said that it had already been rejetted. Not sure how much tho. I can't wait for this rain to stop so I can really ride it. :evil: I was so tired and sore from riding Sat. that I didn't want to ride it right after he took the cover off.

Thanks for the info!

What does removing the air box and putting striaght K&N air filters from the carbs do?....on a shee

 

[370banshee]

i've had mine in stanfing water before with no problems. you really have to be in pretty deep for quite a while to get water in it. if you getthe toomey2-1 filter it sits really high in the frame. guess it just matters how deep of water your going through. just remember it's a quad not a submarine

Essentially it puts the least amount of restriction (besides runnin without filters, haha) which allows more air to enter the mixture. Unless you have some big jets you're going to kill your motor doing this. I'm sure most of the guys with banshees here have upgraded to bigger and better things.

If you keep adding more fuel by going with bigger jets you'll eventually reach a point where you'll be running too rich with gasoline and not enough air to burn properly. That's why people switch to less restrictive air filters, add 1inch round filter holes to their lids, run without lids (my case), or run without the airbox entirely. It all depends on what the manufacturers of your add-on parts suggest. After adding a few though it's mainly a guessing game and paying close attention to how your spark plugs look.

If anyone's got any additions/corrections please feel free to enlighten me!

 

[ReeperLT500]

What I started doing is richen up the mixture and checking the spark plug after about an hour of riding. If plug is white I'll either adjust the needle or change to a cooler plug or both if need. -Mark

 

[370banshee]

yeah you have to "read" the plug. white plug = lean so bigger main jet usually. a needle settign might change it a little but if you lean enough for a white plug i'd bump up a size or twn on the main. tan= good. black= rich. back off on the main a size or two at a time until the plug is tan.
