No Bou won. That was the best Sheffield for a while IMHO. I think I was most impressed with Dabill, he gave it 110%. really good night!

Recently I had a thread going regarding a problem I was having with my 06 SY250. After months of frustration I eventually had to find the problem for myself and traced it to be a faulty CDI and Rectifier. Having put new ones on, the bike ran better than ever for the three trials I have done on it since. However, 2 days ago I went out for a ride and the problem appears to have come back. I ran the bike for an hour and a half and the fan was cutting in within 20 minutes of riding, so it was warm. The bike wont rev past half throttle. Its like 4 stroking at the top end. It was struggling to go up a 2 ft. rock! I took the bike around the field a few times to try and clear it out. Put it in 4th gear, and rode accross the field opened it up to just before 3/4 throttle and it was 4 stroking badly. Had to call it a day. I've spent months going over this bike last time tracing the problem and i'm incredibly frustrated. Birketts appear to be shut until after new year, but i have an entry for the Vic Brittain trial on the 7th and would like to get it sorted. Any body have any ideas what to check or look for etc!!?? Thank you.

I did this mod ages ago for when I had gassers. You can get them from gasgasuk. makes the clutch loads lighter on the scorpa. imho.

Ive fitted a lighter flywheel (about half of it off) and advanced the timing plate and its about the same as my mates 07 250 gasser with a keihin carb on. but i like it because it still grips extremely well. best bike ive ever had. The other week I put on a larger clutch m/cylinder and its made the clutch a lot lighter. You will notice a big difference with the lighter flywheel and is well worth doing IMO good luck with it.

most of the damage on my 06 has happened from washing it. You have to be careful. Best is to wash the plastics with some hot water and with some car shampoo and a sponge. The paint on the tank is fine though. Genarally the paint has only come off on the back mudguard. A replacement is

Yep, never really been a fan of betas but... thats a nice looking bike! How it goes though is a different matter. If thats the final RRP of it, I'd buy a 4rt Nice bike!

Found the problem - duff CDI and rectifier! Put on a different one and the bike ran better than it ever has done - possibly a problem from the word go - sorting it out with the dealer the week. Thanks for all your helpful comments. Hope I can get out this weekend and ride it properly! Shows theres a first time for everything!! Thanks again

Hi sorry for being so long to update. dfwilson - no have not had anything like that happen, thanks anyway I have eliminated the carb because it ran absolutly crap on sunday. Poping and banging. Reeds are ok etc. So now its down to electrics Got my mates bike here (he's kindly lent it to me while he goes on holiday ) so I can try the coil and the CDI. would like to ride a trial on sunday for the first time in 2 months! will let you know when its sorted.

Yes it is connected. Went out on it today with a different carb on with standard settings. The bike ran crap. It was still pinking, wouldnt rev, hunting. Theirs also like a 'murmer' from the engine, like after you've ridden down the road for a few miles... if you know what i mean . went back, put on my mates spark plug which is a Denso (ive been running NGK Platinum) the bike didnt seem any better. rode around for a bit and wasnt happy. played about with the mixture on the carb untill it seemed to run at its best which was another full turn richer than standard! Still not convinced its the carb because it came off a bike which runs spot on and on mine made no difference untill I richened it a lot. I was pushed for time a bit today so will be riding it on sunday as is for most of the day... if it will run properly. if it isnt the carb, then surely its into electrics? cheers...

Hi blockbob. ye the pinging started at the same time as the misfiring etc, which is odd because they may be two different things? I've been running the ignition advanced (just before the indicator recommended) since it was new and it has never done it before. Ill hopefully be going out on it tommorrow but the bikes are relativly simple, all that can be swapped is the carb and the CDI unit. Ill report back tomoz Thanks again

No the carb is mint. Never actually taken it off untill a month ago! there was nowt in there tho. Got an airline on all the jets etc. Yes the wiring for the lights have been taken off...... more explanation needed lpb cheers

Thanks for the suggestions Baldilocks; Yep, the fan is cutting in properly so it is'nt getting hot. Also it has'nt lost any coolant. Checked all the connections etc cleaned all with electrical contact cleaner. no different. Reeds are OK. P.A; checked the filter in the tap and its clean. ScorpaF ; I have tried the bike without the inline breather at the cap. No different. I also cut the breather pipe down when I first got the bike so it has no contact with the exhaust and is fine. I was running a Hope fuel cap on the bike but put the origianal one back on for the trial yesterday and did'nt help. Had to retire from the trial yesterday (second time in the past month) coz the bike was running so sick. Then it back fired and blew the mid-box which leads to believe its electrical. Had a go on my mates 05 and it runs better than mine ever has done! He's kindly offered to lend me parts off his bike to swap n try. Thanks again for your thoughts....

Got a problem with my 06 scorpa (7 months old) thats been doin my head in for the past month. to cut a long story short; it wont rev out; its pinging - and the strange one, when riding a section on any kind of hill/bank, it start fluffing all the way up, loses its power and when you get to the top its fine again . Its died on me in sections and then it will start first kick and will run fine for about a lap... untill it starts pis**n' about again. it used to rev really clean at the top end but now i'm lucky if it revs clean past mid range. The spark plugs a couple of weeks old and is chocolate brown. when the spark plug was replaced, it made no difference. The pinging started at the same time. richened it 1/4 turn at the carb. no difference. dont want to go any more as the bike struggles to rev as it is. The boging down on hills/fluffing I thought it was the floats in the carb but they are correct. All the jets are correct. dont know what else to check. It has been to the dealer twice, cant find anything wrong with it. Phoned birketts twice they cant think what it is. I origianally thought it was the carb but, i'm adamant now it is electrical. both the dealer and birketts said it absolutly wont be! Tried all the usual disconnect the kill button etc hasnt done anything either. I'm running the air filter dry as recommended with different filters and still the same. I'm trying parts off a mates bike this week and going to see what happens but in the mean time..... thoughts??!! cheers.

Gaz, give Daz my regards if you can. that sounded like a horrible crash! I'll probably phone them later in the week see how he is. cheers.

AT LAST!!! scorpa italy

Thanks for that. yeah i have a link, shizenyama if you can read japanese! They dont sell it out of Japan. It has the narita brothers, isao shibuya, tomoyuki ogawa and a lot more. Do you reckon this ties in with atomants topic of the future of trials??

My mate tried a dellorto & keihin carbs on his a couple of years ago and no difference! only had that 1 bike a year and sold it. did his head in.

anyone know where you can get that dvd!!? I have the japanese one thats like that called Re:born which is pretty good.

High compresion head, bigger flywheel, exhaust changes, slightly different frame (dont know wheather that means design or colour?) and apparently blue... doubt they would put the 2T in the 4T frame. Pictures.. we need pictures!

from what i've gathered the 2T is still going to be the main volume bike! exhaust changes, different head, graphics and some other stuff but cant remember!

I'm riding. Did it for the first time last year and was prob the best trial i've done. One of the first riders off on Saturday on the national line (if not the first ) but like Doogle, good number for sunday after saturday night. Is there a full entry list Cubby?

You mean like the bomb proof Scorpa Yamaha or the technological Montesa Honda? Or am I misinterpreting what you said

Hey Atom I really like that! Get some black 'bars and a radycool carbon headlight and then get some '03 yellow 'Sherco' stickers for the frame

It might even be a '97 if its got a red tank? who knows!?

I had a go of an 06 125 with the race kit fitted a little while ago and i could not believe it was a 125! It was quite firey (obviously not ridiculously) and i'm nearly 14 stone and the thing had no trouble going up 5ft steps. This one had the full racing kit and the timing advanced as much as possible and a couple of other mods (dealers demo bike) , you would'nt believe it though, it felt like a 250.
