  1. Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason. Thanks for any input!

    Jetting help please

    I just have the spring in, holes are un-drilled. Jets and needle are all keihin. Do you think I should be looking at the mainjet or pilot?

    Jetting help please

    I'm having a minor stalling issue with my current carb setup, hoping to get some of your opinions before I tear it down. Carb setup: Jetting is 55/158 as per Dave's mod Stock needle shimmed .025" Dynojet soft slide spring Air screw 2.5 turns out Fresh Uni filter Airbox snorkel removed Baffle removed from stock exhaust Altitude is sea level Gas is ethanol free 91 I also did Spud's Battery relocation mod, which might restrict airflow slightly. My issue: The bike seems to run fine at most RPM, however if the bike is below normal idle RPM, (on the edge of stalling), blipping the throttle will cause it to cut out. If the throttle is blipped at idle the bike does not stall or noticeably bog, but there seems to be a slight hesitation before it climbs revs. It also smells somewhat rich just above idle. I've tried messing with the air screw, but that does not seem to help much. When I pull the carb my current plan is to take out the dynojet spring to eliminate it as a point of failure. If that doesn't solve my issue, I'll remove the shim from the needle and go down one mainjet size, as I suspect the bike might be running rich off idle. Any suggestions are appreciated, especially of you've experienced a similar issue.
  5. Dude's asking 2800. I'd say it will probably sell at that price in my area.
  6. I don't think the current owner knows.
  7. Im currently in the market for an xr400r, and considering buying one that's had some heavy engine work done. The current owner claims to have bought it from a friend who's an XR enthusiast. The PO installed a big bore kit and high comp piston, as well as a xrs only pumper carb, rsw triple clamp, aftermarket clutch, street lights, and a whole bunch of bling. My main concern is the effect the upgrades will have on the engine's longevity. How much quicker will I be going through top ends with the setup on this bike as opposed to a stock setup, and should I be worrying at all about bottom end longevity as well? I wouldn't mind having to eventually redo the top end, but I don't want to deal with a race bike type top end rebuild schedule on an XR. Is there anyone here who's running a bike similar to this one who can give some advice?

    Should I trade in my 650l for a 600r?

    I've never worked on a 600r carb before obviously but most xr's seem to be jetted quite lean from the factory, and from what I've read the 600 does not seem to be an exception. If you put in a uni filter without re-jetting the carb, your bike is probably running extremely lean which could explain why you're down on power.

    School me on the RMX 250

    Cool. Any idea where I can find a model history for this bike, or advice on what years to look for/avoid?

    That can't be all that's different. I'm pretty sure they at least had a wide ratio transmission as well. They also don't seem to have been updated along with the rm's.

    School me on the RMX 250

    So I've been trawling my local Craigslist for enduro 250s and found what looks to be an early year RMX in pretty good condition. Im digging that cheesy early 90's color scheme, but I don't know too much about these bikes and it seems like there isn't a ton of info out there about them in comparison to other Japanese bikes of the era. My main question is about model year differences. Is a late year RMX any different than an early one or were they the same through the entire run? Also, are there any known issues with these bikes? I saw something about the power valve being a common point of failure on another thread but it did not go much in depth. Any other thoughts about the bike would be much appreciated.

    Should I trade in my 650l for a 600r?

    I've nearly given myself heatstroke a few times trying to kickstart a flooded bike after picking it up in rough terrain, I think my mind's made up on keeping the 650L. Any tips for weight loss on the L? I've already taken care of the battery box and smogtopus, anything else major I'm missing?

    My main fear here is going through all the effort and spending all the money to get me a xr600r only to take it out for a ride and not be able to tell the difference between it and my 650l. I don't care about power, just handling in technical terrain. Would you sacrifice an e-start just to drop that twenty pounds to make it handle better in the rough stuff?
  14. I live in Upstate New York, and as a consequence of my great state's ban on all things fun it is not possible to register any bike for road use that has "Off road only" or anything similar written on the title. What I'm hoping to do here is bring my off road only title into a VT DMV, and get back something that I can bring into a NY DMV to get me NY street plates. I know VT does not title bikes less than 250cc, instead they give you a certificate of origin. If you bring in an out of state title with off road only on it, will the CO they give you also say off road only? What about bikes they do title? Can you get a normal VT street title for a dirt bike >250cc?

    Should I trade in my 650l for a 600r?

    So I'm still in two minds about this dilemma. At this point im leaning towards keeping and building up my 650l, but I have one more question. Does anyone know if the 650l has a significantly different cam or porting to the 600r? Once I do all the weight loss mods to the L can I just slap in a hi comp piston and have a big bore 600r with e-start or is it more complicated than that?
