Okay....I have, over time, removed exhaust and intake restictors, drilled holes in the airbox and gotten a new carb and installed it. The thing runs pretty good but it dies if left to idle too long after warmup. It also has a little bit of haesitation that goes away for the most part after it is warmed up. I took the old carb apart and it had some crud in it. I cleaned it up real nice and raised the needle one notch and removed the piggyback jet. I installed it tonight and the throttle response was much better even cold. I fiddled with the mixture and idle screws a bit after it warmed up....and it still isn't just right. my main problem is that I don't have a book for this thing and I don't know which screw is which. Could somebody throw me a bone here on which screw is what and a good starting point to dial this thing in?

Thanks

 

Don't be shy, just shout it out if you know the answer. Or better yet reply to this thread. You know the screws that I mean. One is slotted and one is phillips head coming out of the side of the carb. That thing in the hole in the plastic beside the right calf......Is this thing on? Tuff crowd.

 

The phillips one is the air screw, have you rejeted after your mods, prolly need to if you have not.

 

Thank you for your response. I have no rejetted. Was waiting til I put on a pipe. It starts much easier and doesn't stall anymore. Seems to go pretty good now. I haven't had it "out" since, but probably will this weekend. Are jets something the dealer will have or do I need to get them online? I did ream it out a bit with a .022" jet drill when I was claning it out. The orfice may have opened up about 5 thou.

 

Not sure if the dealer will have them in stock but if they are worth a poot, they can get em for you.. just be carefull and not run it lean.. if you opened up the air box you prolly need to check the jetting. too much heat = bad for motor..

 

Worth a "poot" huh? Must be a missouri thing. I didn't see a size stamped on that thing anywhere, I could barely see the little booger itself. What size is it, stock one anyway, and what would you recommend going up to? I am going to try to dial this thing in tonight and I'll put a fresh plug in to see how it looks.I assume you must have done similar mods and found something that worked for you. Thanks again for your help.

 

The stock one in mine was a 55 (I say mine, but it's my daughters[img]i/expressions/face-icon-small-smile.gif[/img]) I have since moved up to a 72.5, but I do have a ct racing pipe. best thing to do I have found is to just keep moving up on the main jet untill you get it to cut out, (rich) at full throttle then move down a size. then just check the plug now and again. When you pipe it you will have to go bigger i'm sure, and if you remove the oil injection that causes a jet change also. It's also not a bad idea to go with a cooler plug too. the poot thing was just me trying not to say a bad word..[img]i/expressions/face-icon-small-wink.gif[/img]

 

well med hows that thing run with that pipe. have you put the K@N on yet if not its a must do. im only running a 70 main was thinking of jumping up to a 75 you think that might be to much fuel. maybee ill order both the 75 n 72.5. man did them works shocks really make this thing handle better and there no heavier than stock.

 

I run a dual element foam filter on the daughters lt it seems to do pretty good. So the shocks really do help huh? do they give it more travel or just better dampening? I don't think it's something I will do since mine will prolly move up to her 90 next year, so the money will have to go to suspension for it, but I do have another daughter that's 2 now so in the future hopefully she will like to ride the little lt.

 

They have about an extra 2 inc. of travel an they really help the dampning my son takes the woops alot more stable he guns it now. that is a little steep for those shocks but nicks got 2 more race seasons to run on this thing so he needs them.
