After my Winter layup and the fitting of the 300 kit, I heat cycled my 21 motor and it ran sweetly. Upon trying to ride on the road the bike had a pronounced flat spot at 4/5thou and would not rev beyond 10thou. If I shut the throttle and opened it quickly the motor would give a small backfire. I sent the bike in to Apex, they thought it could be a faulty coil. This was replaced along with a topend strip down and rebuild and a tweek to the carburation. The problem was still there! Jo suggested that it might be a faulty TPS or even the wiring harnesswas to blame. I have the bike back home now and am looking for any advise on TPS problems. I am "Green" when it comes to electrics. Is there any way of testing if my TPS is working as it should? If the bike is static things are ok, but once on the move"and jolting around" it is as if I have a loose connection somewhere. I have priced up a new TPS and they 'aint cheap. As an aside , I have unplugged and removed the three wires from the sidestand that clip into a conector under the seat area. (for athetic reasons) Please tell me that this is not the cause of my probs. The bike ran ok before with both wire splices "GPS and speed limiter". Any suggestion will be most welcome.
