Thanks guys, 0007, what causes pre ignition?

Hi all, Last year I stripped the engine on my 05 rev3, and replaced the seals, all was running great for about 4/5 trials, then, midway through a trial the engine started to rev it's bits off! And I couldn't shut it off, in the end it seized up and I had to have a new piston and relined barrel. I have checked the carb and the slide is running smoothly and shutting off crisply, the cable is ok and moves freely, has anyone any idea what caused this as I'm about to start her up for the first time, and I don't want to blow the engine again.I also checked the reeds and they were ok. Thanks Tony.

I'm sure I have seen on this forum how to adjust the float level on a 06 250,but can't find it now can you help please.

Hi All, My 06 Scorpa 250 Wont run, it fires but only runs for a few seconds then peters out! any ideas? I have had the carb off and cleaned it and blown it through, it was running ok.

Thanks Pete, a great help ta.

Pete, Where exactly is the oil level hole?

tHE ONLY TROUBLE IS THERE IS NO SIGHT GLASS

Hi, Can someone help me please, I have an 06 scorpa I'm changing the gear oil on, on the caseing it says 700 CM3, is that 700 ml? cheers.

HI all, I have had my engine out for some work etc on my rev3 05 which has taken some time, on putting my carb back I noticed there is a fitting for a small pipe/hose on the underside of the float bowl, but I can't for the life of me remember what was on there,or where it goes to. Any ideas please, cheers, Tony.

Thanks Neville, Just e-mailed Steve, cheers

I had the stator rewound at West country windings, checked the earths, the only thing I hav'nt changed is the coil/ plug cap, do you think that could be playing up?

Hi Guys, Thanks to you lot, I've finally got my 2005 Beta 250 engine built and in,I've had the bearings bore,rings, etc checked, new oil seals, gaskets etc, got a new CDI? (black box) had the stator rewound. When I try to start it, it kicks back really badly but won't start, when I put the stator back I put in the same position there were indents where it had been, I've tried moving it in the same direction as the crank (retard)?still won't start but now it backfires though the exhaust.Please help I'm at my wits end, I've done all this and it's the same as when I started!!!

Cheers Paul, I think it's the bearing gone on the gear lever side of the selector cam, it's so baggy it just pushes it to one side and jaming up, I'll let you know when I get a new bearing, Ta, Tone.

Guys, I have had my engine apart, and have assembled it and can't select any gear, I have split the engine again and it's still impossible to change gear even though there is no pressure on it. What am I doing wrong?
