My son has a classic and has recently replaced the Throttle position sensor after doing a diaognostic test. It will not now start turns over allright but doent seam to fireup. The first couple of times he turned it over after fitting the sensor it started but cut out as soon as you put your foot on the throttle.

Please any hint as what this might be

They need to be setup after replacement, usually if taking of to clean you should mark its postion so that you can replace it in exactly the same position. There is a thread here that advises of the setup procedure. http://bbs.22b.com/cgi-bin/ultimateb...c;f=9;t=000556.

Hope it helps.
