    Well, I found the overheat problem. The impeller is cracked and one fin is all the way gone. I don't see any holes or cracks in the housing but I really am not sure where to look exactly. Not trying to hijack OP's thread. :freaky

    Sorry to bring up an old thread but I am being offered a Beta Techno 290 in exchange for a set of KTM 950 Heads/cams. Its in Immaculate condition. Low Hours/Miles. Basically about $1,000 worth of parts.

    I would say that's a good deal. displacement should be 270 not 290.

    Only the 1999 Techno was available as a 270. All the older Techno were 250cc. I paid $1,000 for my 96 Techno with title and Green Sticker. Which is a good deal. If you watch CL most 90s well used trials bikes are listed closer to $1,500.

    I have had a ton of fun with it for a fraction of the maintenance as a KTM.

    Be adviced Beta did not follow DMV VIN number standards. It can be impossible to get a OHV sticker for one with no title.

    I would be intereted in buying it if you want to make a quick buck . :deal

    The `98 beta came out with a 280. They were late, so the first order had a 250 with the 280 cylinder, piston and head included in the crate. I made a `96 with this kit `just because I had it`. So it is possible. Beta never had a 290 till the EVO.

    I have a 97 Techno and the only way it starts if the throttle is wide open, and also when riding up a hill it will stall out? I'm thinking it's all connected? or may be a float level issue, does anyone know what the float level is?
    Thanks

    I does not sound like a float level issue to me. Too high of a float level and the carb overflows. Too low and you starve for fuel when you hold it wide open too long. I would pull the cab and clean it and check your jet sizes. Did it ever run right? I have had great luck running a 30 pilot and 145 main.

    The starting problem is likely a plugged pilot jet. But while you are in there check everything including the choke. Jet size will vary by elevation. 3000-5000 140. 5000-7000 135, 8000 = 130. Good luck!:D
