SS valves- 250X

Recommended Posts

I just got back from 600 mi Mex ride with Ferrea SS intake valves and PC springs from Randy at Fastman Racing. We rode rain, snow, mud and dust so it was a good test for the valves reliability. All the carb vent tubes were filtered. There was no valve clearance change but I think it is still too early to say they will last several thousand miles. No noticable power loss and the bike was ridden hard. Geno :cry:

Geno1: Why did you do the Stainless Steel intake valves only, and not exhaust also? I see on the 450X specs they have the opposite, Ti intake and SS exhaust. I want to ride my bike without counting the minutes to my next rebuild...

Z- Start clutch worked great and no problems with wear. IMHO it is eaiser on the clutch plates and motor.

The exhausts are already stainless on the 250.

I thought all the valves were TI on the 250X?

From the Hondanews website:

"Unicam valve train features a carburized single camshaft that directly actuates two 31mm titanium intake valves. The camshaft exhaust lobe actuates two 26mm steel exhaust valves via a forked, low-friction, roller rocker-arm.

Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height. "

      So I have never actually posted on one if these forums. I usually just stalk them to get answers but I messed up and I might be out 800 bucks🙃
      I have a 2013 CRF250L that I recently bought and I wanted to get supermoto wheels for it. I got online and almost ordered a set of warp 9 wheels but then I saw an add on Craigslist. Long story short I purchased lightly used warp9 wheels from a 2012 CRF250X not realizing the axles are different sizes. The rims are the same size as what comes in the kit from warp 9 but the spacers and bearings are larger on the wheels that I got. Does anyone know if I can buy new bearing and spacer kits to go in these hubs to fit them on my bike or will I need to purchase new hubs entirely? 
      I work on a fishing boat and I'm off the coast of Oregon for a few weeks and wanted to order something so I can get these wheels on my bike when I get home.
      Thanks, 
      The guy who f***** up

      I was working on installing new needle for JD jet kit today. While trying to get a bit more rotation on the carb i broke a little plastic tee on the top of carb (left side). I think its some sort of vent? Not sure if the brass part is threaded into carb or not? At any rate it will have to be replaced. Wonder where i'd get this little item?
      Any ideas?
      Thanks joe

      Ever been bored or really ticked off by not being able to reach your fuel screw for trailside adjustments?  Well, I decided to do something about it, and not spend a bunch of money to boot!
      Parts liste included:
      Short length of brass tube. Short piece of old, broken speedometer inner cable. Nut from the rejects bin.   I welded the nut to the speedometer cable inner and soldered the other end to the fuel screw using the brass tube as a connector.  I didn't need or fab up a holder for the end, but I wouldn't be too hard. My DIY flexible fuel mixture screw works great and the price is right! I highly recommend this mod.

      Cheap, but effective DIY fuel mixture screw

      Hi everyone. I’m new here so I don’t really know what to do but let me explain what’s up, so I bought this 2008 CRF250X today and everything looked in tip top shape, but within a few minutes of riding the engine and radiator gets to hot to touch and then the bike dies at low RPM, then it is a hassle to get it started(i drained the battery trying) and once it fires it dies super easily again like by touching the trottle or just idling and I have to be super cautious on the throttle to grt it going. I don’t know if it is overheating or if there is another problem, if anyone could help me it would be very much appreciated.
