Could someone tell me the stock jetting for my 1987 Suzuki LT230S Quadsport? Also, is an aftermarket exhaust system worth the money? I am already running a Uni filter with two one inch holes in the airbox lid. Other than that the quad is stock. Thanks a lot.

 

no one knows the stock jetting for a 1987 LT230S? anyone?

 

Stock LT230S Jetting is 112.5 on main and pilot is 20. I have an LT230s also and have the Xcellerator pipe and K&N filter with top lid off and runs great now that I rejetted carb. Once I put that pipe on it started popping like crazy. Cut out when I would floor it and crackle down shifting. Now I found that a 120 main and 22.5 jet is ok(might try one size bigger just for poops & giggles). And here in CA I ran the needle two notches up. Plug it black but dry too. White plug means lean and wet plug is rich. Now I got less popping(maybe just occasional overloading) and more top end than ever before. My wife says its a great bike, as its hers...lol. And yes the pipe will open a wider powerband and more mid to top end power. Sounds great too!! Kinda like a suzuki TL1000...lol....but not as loud. Hope that helped. Let me know what happens. Take care.

 

Where can you get jets. I have a mikuni carb on my 87.

 

how loud of a pipe do you want i bought mine with a dg rcm on it and it is just as loud as a straight pipe but it has a spark arrestor on it.

 

Can anyone tell me how to adjust the valves. I've never had to do it before since this is my first quad.

 

Any good atv/motorcycle store will carry the jets. Ask for atv offroad mikuini carb jets. Have fun.

 

jetsrus.com has genuine mikuni jets

 

im having same prob with my dg rcm popping and all that... i tried adjusting pilot air screw?? and first time it was too cold , but second time it got a lil better! so ANYONE have a clue as to where i can find a jet kit or the jets i need to fix this prob.....gettin ready to beef this motor a lil by polishing the ports and such but figure right now big waste of time since its too lean.......and it sucks cause this thing is fun and it has reverse[img]i/expressions/face-icon-small-happy.gif[/img]
