The bike would flip over if I didn't!

 

Ok. This is my first tie posting on here (new member). I have been reading the posts and find that you guys are pretty helpful. So here is what I got. My dad bought ,what he says, is an 85' 250. Rode it once and decided to go 4-stroke. So he gave me the bike. Its in really good shape. Just got back from a 5 day trip to sand mountain in Nevada and it performed well. Now the guy that had the bike before my dad did alot to clean it up and make it rideable. The only thing that broke on us was a brake line connector and his homemade exhaust. After looking at alot of pics of 85' 250's, I noticed that my plastics dont match the pics of other 85's. My radiator shroud and fenders look like those of an 86' (I think). I will try to figure out how to post pics soon. The only mods I want to do are new shocks (front and rear), a fmf fatty pipe and a new carb. I can handle the suspension and pipe upgrades ,but not sure where to start for searching a new carb. I'd like to go a little hotter on the carb ,but right now I would be happy with just being able to adjust it. The current one is pretty wore out. My brother-in-law went through and cleaned it up ,but we still cant adjust it. Turining the screws does nothing. The needles are fine according to him. So I would rather put a new one on. So where do I go for a new carb.? And is there good places online to find aftermarket stuff for my "vintage" sand screamer? And I guess any advice you guys could throw my way would be helpful. I am not new to the off-road scene, but this is my first quad. Thanks.

 

Personally I would just get a new carb kit and rebuild the old carb, unless I was doing some engine mods I wouldn't change it. As for a new carb your best bet might be e-bay or a Zuk dealer, which will probably be over priced. You also might can try vincescycle.com he sales alot of aftermarket items for the 230, but I am not sure about the 2 strokes, he is normally quick at replies and has fair prices. My suggestion would be get a carb kit rebuild the carb, pipe it and rejet it, new shocks and hit the dirt - or sand - which ever.

All right, you and I have the same issue with hot starting. Ive got this one figured out. Its runing rich, if it wont start hot, give it about half to 3/4 throttle when you kick it over.
Works every time, in my case anyway.


Good Luck.

Yeah, I sorta came to the same conclusion from looking at the plug and tinkering. I have the needle clip at the top most position and took the washer that was under the needle clip and put it on top of the clip so the needle is the farthest it can be in the slide. I also have the airbox cover off and I took out 2 big screws from the exhaust and that seems to relieve some backpressure (not sure why those screws are there). Finally I have the plug looking about right, but I lost some power I think. I can manage to get it started now, but not very reliably. Sometimes it fires right up and sometimes I have to kick 20-30 times. I have tried the "open throttle" technique before. Not sure if it helps or not. It seems reasonable. But my question now is why would a bike that is bored out with higher compression piston and K&N filter with no box cover and less exhaust pressure need a smaller jet????

Do you know the stock plug for this bike? Mine has the NGK DE7A I think it said. You know if 8 is hotter than 7 or the other way around? I have an 8 I could use out of my bayou.

 

i believe that 7 is hotter, but im not 100% sure

 

One of these days I'll get around to looking at the NGK site,,, just haven't gotten around to it. My instinct was 7 is hotter too.

 

well i got you an answer
-Knowing which plugs are hotter or colder than the ones you presently have in your bike is easy if you're content to stay with the same brand. Nearly all of the world's plug makers use a number-based code to designate heat range: foreign firms follow a system in which higher numbers mean colder plugs; American companies do just the opposite, assigning hotter plugs higher numbers. Unfortunately, there is no semblance of order beyond this point. One company, Champion, is in a state of nomenclature transition that makes its product line inordinately confusing. The American Rule applies at Champion, but in an odd way, spread across three series of heat ranges that encompass touring and racing spark plugs, old and new, with double-digit numbers assigned to some and single digits for others.

Alright guys i am tired of my carb ordeal, it wont idle at all anymore. so i finally just bought a 300ex carb off ebay for $25 shipped. not too bad. i took the suzuki apart and messing around with it i found it will need some modifications. we're going to our cabin tomorrow to ride so i threw it back together quickly. i found that the bigger carb fits in the intake boot, but it is stretched pretty good. i was thinking about taking the old head i have and having it sent to a specialist to rework the flow and make the port bigger to go with the carb. while im at it i might as well get a new web cam, maybe the race one [img]i/expressions/face-icon-small-smile.gif[/img], along with the titanium valves n springs just to make her run good. what do u guys think??

 

hope the carb works out 4 ya mine wont idle either pizzin me off
