    Looking to buy a <S>2005</S> 2006 Scorpa SY250 it will be my first trials bike, but I have been doing lots of technical riding on my trail bikes.

    Any issues that need special attention with this bike?

    Are parts going to be available if they need replacing (I am in the US)?

    What I want is a reliable bike and it seems this could be the ticket with the Yamaha motor.

    Had many sys very solid bike.parts should not be a problem.Check to see if center exhaust is not cracked had a habit of doing that in that year range.They are a bit tricky to work on carb and motor but if you remove enough parts not bad.Good luck JR

    Parts are much better for Gas Gas, Sherco or Beta. If you are actually planning on competing. Just buying it for the Yamaha motor is crazy. It was a poor (not competitive) design when Yamaha made it in `92. That is why they had so many motors left over. Dependable ,yes.

    No top level competition, Might try some of the lower level stuff but never see myself at an advanced level.

    I've had one for about 3 years. I think that it is a fantastic beginner/novice bike, and it has been very dependable. The few parts I have needed (consumables mainly) have been a non issue.

    I spent a few hours on a new Sherco last week. I honestly think I'm better off having been on the Scorpa vs. something new like that. I also believe that at this point I would benefit from a new bike but I like the Scorpa enough that I'm not in any hurry. It's an easy, mild and forgiving bike.

    Call Mike at the Tryals Shop and talk Scorpa for a bit before you decide. That way you'll know where you stand with parts as Mike is pretty much the only source in the US.

    The bike has now been bought, oh and it is actually a 2006. I am not going to be doing any Expert riding almost surely and even if so it would likely be time for a new bike anyways. I am new to trials but not new to technical trail riding but I have to unlearn a good bit of bad habits picked up from that (a riding buddy does lots of trials and he graciously allowed me to try out his bike).

    Here are some pics of the bike:

    One good thing about the Scorpa... is there used to be a "long ride" seat and tank for these, maybe even available new nowdays? show up from time to time in places like our forum, but not very often.

    It is almost too clean for me, I like to buy them pre-scratched.

    I was thinking about the Long ride seat/tank but it seems very hard to come by and probably very expensive.

    Wonderful looking bike! I had the yellow-black reed valve Rotax 250-based Scorpa. It was a heavy pig but I loved it. I watched and listened to a lot of Yamaha-based Scorpas, and rode one. I found them exceptionally smooth and mellow, which is great for learning.

    A well set up older bike can perform very well, especially against a poorly set up or maintained newer model :clap. Starting out with a not beat up bike is an advantage. Great setup and maintenance and you'll have a heck of a nice ride.

    Yes you will have to remove and clean very good before welder can get a good seal on the split.While you have apart check carb and your clutch slave cylinder is under there also.JR

    What am I looking for on the clutch slave cylinder? I already have cleaned the carb, it was gummed up and not idling well, which now seems good.

    Also, is there any validity to the tank on these bikes having issues with Ethanol gas and shedding a white slime that can clog the carb. Might have to looking into getting AvGas, no non ethanol reasonably priced gas is available.

    Just figured while you had things apart worth looking to make sure everything looks good with clutch cly.you are right with the little white balls JR

    Yes, keep ethanol away from your tank. I've used AVgas and a few different flavors of VP with success. I also have no source for cheap ethanol-free fuel (This is usually where someone posts a link to the websites that list ethanol free gas stations :D). I also don't really have an easy source for AVgas and have settled on VP C9 for a while now. Fortunately, even when I ride a lot, I don't go through a lot of fuel.

    I have not been able to find any local stations for reasonable priced gas(various websites), but I may have a way of getting some avgas. Do these different gas types require different jetting?

    I am getting ready to fix the mid pipe and found this in the tank, Will be getting a fuel filter:

    Here is the damage:

    [​IMG]

    and culprit, Red points to corner and I am wondering if the piece of coolant pipe (yellow arrow) placed there is stock or if it maybe was put there in reaction to this issue, I think it may even make it worse by pushing the midpipe onto the corner:

    So now the question is how much of that corner am I safe to take off without thinning the case, I would assume the entire block is superfluous material but I would rather get some verification first.

    Welding that pipe isnt an easy job, but if you can find a good TIG welder it should be possible. Rather than grinding material off the cases, simply get your welder to out an indent into the pipe, when he repairs the hole.

    Never seen them wear like that mostly split at rear seam.Clean it good and a good welder can fix it.That rubber pc is factory installed.I think you could safely remove that spot on the cases just go slow.I always run race gas in my bikes and no jetting changes needed.

    I am a little confused at the moment, as I see mention of filing down that corner and tearing at the seam. I am now thinking these are separate issues. I should probably see about getting some reinforcement on a commonly cracked seam when fixing the puncture.

    Is this the location of the seam that cracks?
