Dirt Bike Modifications Forum

I'm wanting to make my yz250 street legal but i need help with wiring the lights and blinkers. first off for all of you that think I can't because its a yz, in oregon as long as its 25 years or older you dont need to meet emission or equipment standards.

Im going to just put in a battery and charge it every night before I take it out so the magneto will be seperate from the lights. I know i need a headlight/switch, horn/switch, turn signals/flasher relay, brake light/switch thing, and the battery of course.

does anyone know what I will need to run these? will I need a reulator or rectifier? or is there anything else Im not thinking of?   If anyone has any help with this I would love it! thanks  

umm the yz in your avatar is not 25 years old...the 83 had the pipe coming off the other side. and it was a much different shape. ~pat  
PEACE GUYS ITS BEEN A BLAST!!!!! ~patrick

yeah the one in my avatar is an 85 yz250, im planning on switching frames with an 84 and then having the bike ready for next year.   good observation on the year though  

Why not get a lighting coil and run the lights of the mag? But then again, it being a 25 year old mx bike, theres no way I'd want it on the street. May I ask why? Its gonna buzz, be loud, annoying, get weird looks from cops and wear that bike out in no time. The road is not kind to dirtbikes.

I havn't been able to find any aftermarket lighting coils, ive been thinking about getting a stator/magneto from a yamaha that is set up for lights but that isn't going to happen for a long time if it ever does.

and to respond to you thoughts of a 2-stroke dual-sport...  

well to someone who doesn't appreciate dual-sports, I could see why you wouldn't think this is a good idea. it is true that the suspension of a dirtbike isn't as comfortable as a road bike or even a sport bike, but can you ride your crotchrocket to the mountains then literally ride deep through the mountains, have fun for the day, then drive back on the street while the whole time not worrying about getting that first scratch on your bike? I don't think so!

and to the loudness, buzzing, and looks...

You are OBVIOUSLY not a 2-stroke person thank you very much  

Me not a 2 stroke person???? Except for my first bike, thats all I ever rode was 2 strokes. Have you seen my avatar? Thats a 490 two stroke. And I'm telling you right now, you will not enjoy any off road bike on the road for very long. It will vibrate, it will be loud, and it will get annoying. But do you what you want. Ask any expert here woods, skip, chud, and just about anyone else here and they will tell you an mx bike doesnt belong near the street

we try to keep the flaming off this board so chill out. DCM was giving good advice. he and atk are 2 stroke people, and so am i. putting a yz250 on the road is very bad on the bike. its not made to be ran like that. DCM isnt talking about the suspension. he is talking about the engine, the road is just not good on a two stroke engine. and he did tell you how to hook up lights. if you want a dual sport then i suggest you get like an xr or klx or something along that line. ktm makes very good dual sports that are 2 strokes but they are designed different to be able to be ridden on the road. the yz was designed for dirt and should be kept on dirt. the DR's are also very good dual sports.

haha. jeeesh. do what you want kid. why would you come on here asking advice but not appreciate it no matter what it is? a 2 stroke is not made to be held at a constant fast rpm for any period of time. it will wear down wicked quick. i mean a mx 4 stroke is bad enough. but a 2 stroke? theri ergo's are not made for higher speed. 2 strokes especially yz's wich are motocross bikes do not like road ridineg. take it or leave it. and elko, lol he must have had a brain fart. ~pat

Im not trying to be difficult, im just wanting help with what I will need for everything to work properly. im not looking for anyones opinion or advice on what else to do other than what i already stated i was going to do. ive already thought many times about trying to put in a stator but its just not what im going to do right now, and i am appreciative that i got somewhat suggestive help at the least. i do appreciate you all trying to give me advice because you think i might run into a problem later down the road but thats not what im looking for in this post.

I guess i should have been more specific and less descriptive in my first post. what i want to know is what the purpose of the regulator and rectifier is and also will i need some sort of flasher relay to make the turn signal blink instead of just staying on.  please no opinions, if you have the answers to what i want to know then please tell me.  

just to clarify something... im not telling any of you that you are wrong, i believe you when you say it wont be comfortable and it will wear down a lot faster than a factory-made- dual-sport.  

noone ever said anything about being comfortable but the bike was not designed for that. what we did say though is that you will be destroying a perfectly good bike and i gave you examples of other bikes this will actually work on.

ktm made a couple two-stroke dual-sports and to this day they are still making them and the yamaha wr was a dual-sport, same with the old it models. as far as i know they all use the dry crankcase lubricated only by 2-stroke oil and the wr and it were basically the same bike as the yz's of the same time, but just with lighting kits. is there something different they did to make them more suitable for the road that i don't know of?
i know i will need to hone the cylinder pretty frequently if im going to ride it a lot, but other than the cylinder, what do you think is going to be going bad fast?  

yes all those bikes you mentioned are the same ones that i said. they are designed different. different trannies, different engines.

Sorry elko man I was tired and not thinking. i do think of you as an expert theres just so may dam* people on this board i forget. To the orginal poster, didnt mean to come off harsh, the diffrence in the old 2 stroke enduros and dual sports was less compression, diffrent port timing, diffrent trans gears, and softer suspension. A regulator will keep voltage at a constant, a rectifer changes ac current to dc current, if your running a battery with no charge going into it, then no you will just need to ground it and run your light postive to your battery. Just so you know, a headlight, taillight, turn signals and brakelight will drain the average battery you can fit on a bike very quickly. Just a heads up that you'll run the risk of the battery dieing mid ride and killing it quickly to where it wont hold a charge.
