Hi all. Geoff is the name and Beta Rev3 250 (circa 2002) is the bike.. The Beta was a shed when I got it (my mate bought it unseen as a surprise.. yay cheers for the work I have to now do) and is now In much better fettle. swing arm bearings had disintegrated, both brake calipers and master cylinders where seized. had fun bleeding the rear brake.. its sprung a leak and needs doing again which I am putting off until last as I hated the bike for a while when I did it the first time.. Head bearing were dry and shot, replaced. various plastics missing or damaged. The air filter looked to be years old.. Clutch is weird and grabby, that can't be right on a trials bike surely, with the finesse needed for some manoeuvres? First question: 1. I have had many 2 strokes but this one rattles and knocks, sounds like its pinking. I am told its normal?? What do any of the beta owners have to say about that? 2. After the last use it was put away.. it now has no spark... I know its Italian but ????? Reading forums its likely the stator but I am struggling to get a wiring diagram so I know what goes where. I have basic electrical knowledge and a basic multimeter. Are there some proper tests I can do? Yellow, red, brown, white a B/W terminate at the stator, black comes out of the connector and terminates in a spade connector and does not go to the stator. Both brown and yellow are ‘grounded’, by that I mean I have continuity if I test between the connector and the body or coil pickups. little or no resistance Both white and B/W are also ‘grounded’ but show some resistance. .200 when set to the 2k Ohms settings from wire to stator and .400 between the 2 wires. red I get nothing, it could be broken but I don't want to strip the rubber tubing away just yet. I have attached a pic, anyone able to tell me what year it is.. ignore the decals as I put them on it. Attached Images

Cheers guys. Reposted in the Beta specific forum. Geoff

Hi all. Geoff is the name and Beta Rev3 250 (circa 2002) is the bike.. Been into bikes since I was 16 and currently ride a VTR1000 on the road and will soon ride the Beta off road. My life long friend thought it would be a good idea now we have turned 40 to get trials bikes and an ex-ambulance to ferry them around! I think we need the paramedics as well. The wife's a nurse but I get poor bedside manners if I ever have need of her skills.. The Beta was a shed when I got it (my mate bought it unseen as a surprise.. yay cheers for the work I have to now do) and is now In much better fettle. swing arm bearings had disintegrated, both brake calipers and master cylinders where seized. had fun bleeding the rear brake.. its sprung a leak and needs doing again which I am putting off until last as I hated the bike for a while when I did it the first time.. Head bearing were dry and shot, replaced. various plastics missing or damaged. The air filter looked to be years old.. Clutch is weird and grabby, that can't be right on a trials bike surely, with the finesse needed for some manoeuvres? I am not sure of forum etiquette, am I okay to ask questions from the off or am I supposed to get involved first? First question: 1. I have had many 2 strokes but this one rattles and knocks, sounds like its pinking. I am told its normal?? What do any of the beta owners have to say about that? 2.
