    need help! 07 crf250 kind of seized

    If your head/valves/cam are all good, you are probably looking at about $350 to get it back up and running. If it locked up, your cylinder is probably toast along with your piston. http://www.ebay.com/...=item3f1e785739 My son's 250X started using oil and we didn't check it close enough so the cam lost lubrication. I just tore it down yesterday, it took about 2 hours to get it tore down. No special tools are required. If you know how to check and adjust valves, you have enough capability to get the cylinder and piston off.

    What piston to run in 04 250X?

    Do I need to do anything to the cylinder, like get it honed? It looks really good, cross hatching is still visible all throughout the cylinder.

    What piston to run in 04 250X?

    Time to freshen up the top end on my son's 2004 250X, it has been using oil a lot more than usual and it's time to make it new again. I'm trying to decide what parts to use after we determine if the cylinder is ok. Can I use a newer model piston for more compression? I prefer to use stock Honda parts. I think I saw that a 2008 or 2009 250R piston is the way to go? We are also in the market for a cam, if anyone has a 250R cam or HotCam.

    dr350se tank on dr350 dirt frame

    I think the Clarke tank has mounting options for both bikes. The street tank has pockets that slide over rubber pieces that are mounted on the frame. The dirt tank has brackets mounted to it which bolt to the frame.

    DR350S Fuel Cap

    I could sell just the cap, not planning on using the tank anyway.

    DR350S Fuel Cap

    I have one, swapped the steel tank for a plastic one. I need to get a spare key made for the tank lock, only have the one for my ignition. Interested?

    1990 DR 350s Carburetor Rebuild

    Definitely the BST33 CV carb. If you tune it properly, it's a good carb. The biggest thing is to get it clean first. There is a lot of info online about jetting, including opening up the airbox, so do a bit of research and then get to work! Enjoy!

    1990 DR 350s Carburetor Rebuild

    Buy a petcock for a Yamaha Raptor, direct fit to the DR and it has on/off/reserve positions, completely manual with no vacuum operation. When you replace your stock petcock, you need to cap the vacuum line on the carb that goes to the petcock. For parts, you can check out this site. http://jetsrus.com/carburetor/carb_mikuni_TM33-8012_pumper_carb_exploded_view_parts.html

    quick question

    I run Shell Rotella-T 15W40 in every bike I own. Which oil to use is almost as bad of a topic as religion or politics. Everyone has an opinion and theirs is the best. All I can say is that it hasn't given me any issues. If you ask another person, they will say that it's a matter of time until one of my bikes explodes and takes out a bus load full of nuns and crippled children. Enjoy!

    dr350 running problem

    Checking the valves is not a bad idea, but I'd bet a box of donuts that your carb is gunked up. It will need to be taken apart and cleaned really well. You may want to look up soaking your carb in pine sol, and blow out all the passages with compressed air.

    cracked case half. Can I replace just one side?

    They are supposed to be matched. You should be able to find a set, just might have to wait.

    cluster f'ed

    Sounds like maybe your battery got damaged, due to the dim lights unless you rev it. You can easily remove the key from the cluster, I have done that on mine and am working on getting a DRZ400 digital speedometer cluster installed on my DR350. Good luck.

    Cam chain tensioner location on '96 DR350SE

    Ok, well the best way to measure it is to remove it, let it extend all the way and then put it back into it's mount location.....just by hand, not bolt it in. As you push in the tensioner against the timing chain guide, it should stop and there hopefully will be a gap between the tensioner and the cylinder. If it's pretty close, say less than 1/4 inch then you're close to wore out.

    Cam chain tensioner location on '96 DR350SE

    The tensioner is located on the rear of the cylinder. You don't need to mess with it, it's automatic.
