I put on an SE atv mid bend and like them.

Something was wrong with the primary gears.It was making a knocking noise and vibrated pretty bad when the clutch was let out. I was very discouraged because my bike was damaged during shipping and then after riding it twice it sounded like a freight train. I took the bike back to Don Hubbard and it has been repaired in less than a week. I figured it was going to take a month of dicking around before they would send a new primary set. I am pleased with the way this was handled by everyone involved.

Dan, my bike started knocking so loud I took it to the Dealer to get repaired. Did you dress both sides of the tab or just the side that gets pushed on under load? I took mine apart on sunday and dressed just one side and cleaned out the glue between the friction pads, but it was making so much noise it was making me sick. The dealer has assured me that it is going to me made right. Neil

I took some pictures of mine, but I don't know how to post them. It's a great looking bike, too bad it's a piece of ****!

Dan, when you left 2 springs out, did you put the bolts in or leave them outs as well? My '08 270 clutch is inconsistant and grabby also chatters/chudders and is about as noisy as a Ducati dry clutch with the cover off. It also vibrates to beat hell. I just got the bike and have only ridden it twice. I'm not too happy about it either. Thanks, Neil King

I've never ridden an SY250f or a WR250, however, the gearing is probably going to be a major problem. Traditional trials gearing puts the first 3 gears close togather and 1st gear is pretty low, 4th gear is a large leap from 3rd and 5th is like a normal wide ratio from 4th. The cam profiles are way different, the Sy is going to have little or no overlap for max low end. The carb is also completely different one of the main differences is that a trials motor uses a small throat bore to keep air flow velocity high at low rpm. A WR/YZ motor is a screamer with a rev limit at around 13K an SY is probably going to give out about halfway there due to cam profile and carb flow limits. You might be better off buying 2 bikes and swapping motors. Like I said before I really don't know the specifics of either machine just generalities. Of course you may have known all this already.

I ordered an '08 270, we'll see how I like it. I'm looking forward to riding it at Rio. The next couple of years will be interesting to see how the 4 strokes develop.

I got to ride the bike that came to Austin. The power delivery is much smoother than a 4RT, and it did feel to be about half the size. I didn't notice any excessive starter gear noise, but my 315R makes quite a bit of racket so I may just be used to it. I really liked the bike, but it cost just a little too much for me to spend. You gonna have fun though!

'08 ordered.

Is it worth the extra money for an '08? I there any difference besides the carb and plastics? It may be worth it for resale value alone. Anyone out there who's had both I'd like to hear from you. Or should I buy a an '06 Sherco at half the price? I don't have long to decide. Thanks, Neil King

Are you sure it is getting voltage. You will want to check, those motors ar not cheep.

Lewis Sport has taken over the parts distribution for the US. I don't know about the bikes.

The new WR250X and WR250R from Yamaha with EFI run the same 4-valve motor. Personally, I'd like to see a sidevalve two-valve trials motor, as it would lower the center of gravity of the bike. We certainly don't need twin cams and four valves given the rev range of a trials bike. Isn't that what the gasgas 4t is supposed to be? I think that 4 overhead valves was a great advancement for a single cylinder engine, and multiple cylinder engines for that matter. Kind of like the reed valve for 2 strokes.

I am wondering if the new 250 fi is going to go to trials, I think it might if it proves reliable. I believe the 5 valve engine to be a good design, I have a WR400F and like it. But four valves are probably enough. I haven't seen the new 250 and don't know the weight comparison between the two. What do ya'll think/know? Neil King

No clutch in a section sound dangerous to me.

I fixed my problem. The regulator has an external capacitor and one of the wires was broke off. This was on a 315R, I dont know about the scorpa.

my fan goes off as soon as I rev the motor, whats that mean?

Checked the timing, it was in the middle position, advanced it to maximum, somewhat better. How can you tell which flywheel? I was thinking the same, maybe time for a top end kit, just haven't ridden these for years, the only thing I can compare to is my last bike, 03 yz450F, and I don't think they are in the same category. Try keeping that 450 in a section, you'll find that an underpowerd 250 works better. Try taking that 450 up a 30deg hill with mutiple 2' steps. You can come out alive on the underpowered 250, multiple broken bones on the 450( at least I would). No they are not in the same catagory, I bet that 450 is fun to ride though.

I forgot to mention; I run 105 octane fuel. Running pump gas makes the piston sound like someone is trying to hammer the crap out of it.

Acdelco, sounds like your bike is doing the normal clogged slow jet lean surge. I've had my '00 315r for a year now. The slow jet clogged very easily, I must have cleaned that carb 5 times the first month. Stock setting on the air screw is 1 turn out. If the jet is partialy clogged turning the screw in all the way will help. I ended up drilling the jet out with a small jet bit. It was a lot better but still clogged again, so I drilled another size larger and all has been well. But the screw is 2 and a half turns out. Another thing to check is the o-ring on the air adjustment screw, if it is cracked it will leak causing the same problem as a clogged jet. Elf 740 oil is the best for the gear box, it is expensive but the clutch might actually work. I didn't sell my enduro (wr 400) but I don't ride it very often since I started trials. If you don't have knee/shin guards get some and don't ride without them. Every time I ride without them I land on my knee or shin on a rock. So far every time I think I've gotten better than the bike I learn that with the proper technique the bike will do what it is suppossed to do. Have fun!

No

I've done manual labor most of my life, so I'm in fair shape. I used to play racketball years ago, trials riding gets my heart beating just as good as racketball. When I'm practicing by myself, I don't rest as often as when I'm with someone. Wrestling the bike trying not to fall down, falling anyway, picking myself and the bike up, that gets my heart going.

The 2 paper plates go on the outside. At least that is what I was told, and how I installed mine.

Well............. get a damn bike and get crackin or as in my case wrecking. Wondering what bike to get? If you have a lot of money, get a new one. Or like me(that means no money), get the cheapest thing you can find. Want to know what class to start in? Anyone crazy enough to ride in a sidecar need to start in the master class!!!!!

I feel that a systematic approach is easiest to do if you start at one end of the spectrum and work your way to the other end. The less rebound dampening you have, the easier it is going to be to hop, and harder to control on rocks and logs plus cause traction problems. So, you might want to start with as little dampening as possible and move up from there. But first you will want to set the preload to where you want it, then make the rebound adjustments.
