85 to 88 Suzuki LT230S Quadsport help.
Well i got the cam in. I guess since it runs excellent i didn't mess up the timing at all. It idles great. If i get the rpms up high than cut the engine off the plug is a light greyish brown thats good right? But if i try and nail the throttle from a dead idle it just stalls out. So whats this mean i need to adjust the clip on the needle? Once i get the rpms a lil higher than idle than i can just nail the throttle and it goes just fine.
From a dead idle to about 3/4 throttle, It didn't do that before since thats how i usualy ride (nail it than WOT) im sure i would have noticed it before hand. But it runs to perfect at every other rpm range. So im baffled
Well, all you can really do right now is fiddle around with the needle clip. Try it in different positions and see what happens. Try with the airbox lid back on and see first. If it works with the lid on, you know its running lean and to lower the clip on the needle.
Check out the profile of MalHombre. His mechanic came up with a solution for a spark arrestor on the dg rcm pipe. He has the aluminum exhaust. You can order a replacement screen online as long as you know the inside diameter of the end of the muffler, then fabricate and endcap and drill and tap some holes to fasten it to the muffler. I think his mechanic turned a chunk of billet something on a lathe but I don't imagine you'd have to get that fancy with it maybe send him a p.m. I know he's on here from time to time.
I still have the lid on never took it off. I just got off the phone with a friend who is a seasoned mechanic when it comes to the 230 he said all i should have to do is adjust my piolet screw or change out my piolet jet since it runs at every other rpm with no issue, Im not gonna fiddle with it much since i have the exhaust comming on thursday.

I had a bit of a rough spot just off idle and the only solution I could come up with was grinding the cutout on my slide bigger. But that's on the 28mm carb
The thing is, you can put in a bigger pilot and that will give it more gas just off idle, but then you will have to figure out a way to inject more air into the pilot circuit at idle because it would be too rich and you have the stock carb which has a fuel screw, not an air screw. In other words, if you're set at 1.5 turns out right now and it idles good, upping the pilot jet could mean you have to turn your screw all the way in... or more. This is why carb tuning is an art. One circuit affects the others and you cant fix one thing without messing something else up.

Oh the joy of spark plugs! There is an art to interpretting a sparkplug too, but I don't know it. Yeah, brown is what you want, but did you run it right to get the brown? The way I used to do it was get the quad warm, put new plug in and go full bore across my field as hard as I could go then pull the clutch and hit the kill switch at same time. Yank the plug out and look.
