I hear a lot about JHP but who are they ? And where can you buy them ? £30 seems a lot cheaper than £125 for a FIM chip from Sigma !
As regards the CO trim, I had been experincing slight "missing" around 3000 rpm, the trim pot was found just lean of centre so I set it to the mid point today and found the missing almost gone. Perhaps a slight richening may completly rmove it, I,ll try next week . I dont have a CO meter at the moment so am not sure the percentage. I am lead to believe the trim pot will have an effect across the rev range, but less so at the highter rpm ?
Allways glad for technical advice, cheers.
