"Sir do you know how many valves i had to change this Year??? INDEED!!! 0" "Oh i changed my oil to one that has a Strawberry scent, so when i sweep past your inferior 4t you can smell something nice" Now that i think most of the time 2 stroke riders are a bit snobish.... |

I have also been looking into the Orion street legal version. I learned to ride on a Yamaha XT250 and the power seems to be similar on paper. That was a great trail bike and am looking into getting another dualsport as my second Bike. Think im going to pull the trigger on it soon.
newish to this forum, any good threads for modding the Orion 250? Hell might even throw a sheepskin on the seat and some soft saddlebags and make it a mini adv. |

I can guarantee you I can do a 2 stoke top end in less time then I can adjust my valves on my KLX. A shimmed setup can take putting the top end in and out several times before getting it right. The high performance 4 stroke stuff in modern MX bikes is nothing like these air cooled motors. 12000 plus RPM's can really beat those things up, intervals of 50 hours aren't unheard of.

I do love the Orion RXB-250 but I can't seem to find it on either the 'ON-ROAD' or the 'OFF-ROAD' EPA/FMVSS lists-so-they are a NO-GO here in Colorado. Orion claims it has a Zongshen 249cc with an overhead cam (which is what I want!) They also claim a whopping 19.5 HP with a 5 speed. I even emailed them awhile ago as to the manufacturer...with no response...so there's that! It lists for $2099 with "free home delivery."

I'm mainly playing devils advocate here, and freely admit that for most on here doing a valve check on these is really a non issue, and no comparison to a top end swap.

The reason I am adamant about the 4 strokes isn't just the idea of servicing. As I said, it is valve checks, not just servicing. The valves might not need a service until the second or 3rd check, and yes if you have to wait for parts, such as shims, it can take a while, but the actual work itself isn't any more time consuming once you know how to go about it. It might feel more tedious to be sure, but time involved? nah. Admittedly, some 4 strokes are better than others. Most of Honda's 4 strokes are fairly easy to do a valve check, which is what I have the most experience with. I am, after all, a huge Honda fanboy lol. You are correct though, service of a 2 stroke top end is easy. There is nothing there to get in the way other than head and cylinder bolts. Plus, a big aspect of 2 stroke service that many 2 stroke enthusiasts love to leave out is seal leakage and crank/rod service/repair. In my experience dealing with both, the 4 stroke wins here time after time. Leaking seals on a 2 stroke is a huge deal in terms of power and rideability. They also punish the crap out of the rod bearings and crank, so they often need replacement much more often. Just the nature of the beast. Like I said, I love a good 2 stroke as much as a good 4 stroke. I just try to be realistic about both.

Plus jetting is more annoying on a 2T than in a 4T, even more if you use premix, just trying to mix at a different % will throw off jetting.. |
