my dad has had his lt250r ever since he was 15.it still runs.i want to fix it up for him as a surprise so he could see that i can handle engines and stuff.i have all the tools i need to fix i.i want to make it faster, and look better.we race it every first saturday at orlando speed world in floida.i want to get the whole thing redone.i just need guidance on it.i can handle all of the work and i know that he will be surprised when i am done with it.i know that he wants to bore it 20 over, and tha i will need to tighten the chain and i need to fix the plastics and reweld the front headlight back on and fix the front grill on it.i want to keep it stock parts but just modified.any body please e-mail me with advice or just directions on how to do stuff to it.thankx

 

Let me know where you want to start and i'll do my best to get you through it. If i don't reply to this thread over the weekend don't get worried, the weather is great here and i plan on riding all weekend.

 

i would really start any where.i just need the directions on how and what to do.but if i would have to chose i would start with the intake and exhaust.thanks

 

ok lets start with the intake. How much do you want to spend?

Some good mods would be remove the air box lid, put in a high flow filter, replace the stock 32mm carb with a 36mm+ carb, better reeds

Cost in the order i listed them:
free, $30, ~$50(ebay), $40

exhuast: this is where it gets expensive. get a LRD or FTZ pipe and silencer

finally rejet it correctly and you have some nice power already

 

thanks for those. the quad keeps boggin out and i dont know why.is there something wrong that can be fixed or what?thanx

 

It could be bogging for a ton of reasons. Carb, or worn out motor out top end would be my first off hand guesses. I'd get a bearing kit off e-bay(60-85) that includes all the bearings on the bike.

 

alright so now i know what to do for the intake, exhaust, and a little bit of how i can fix the bogging, is there anything else that i can do to enhance this quad?thanks

 

There are lots of things. These, of course, are limited by money. I'm sure it could use new a arm bushiings, and tie rod ends. This would take up the play in the steering, and tighten up the front end. Having the head shaved is a cheap way to make a little power, if you are going to do any motor work. Then you can have the ports cleaned up.

 

i know money is the one thig that i would need but for now i just want to get a list of priorities set and then werk on them one by one.i was wondering if any one could tell me how to bore the quad 50 over and what/how to port and polish it?i really dont know that much about engines, only the basics, but im taking classes to learn all that i can.thanks.you could just email me at jor1216@webtv.net

 

You can't bore an engine, or port them either. Take them to a reputable machine shop.
