hi can anybody tell me what is the reason for the Revs clock to not work correctly, ie on tick over its either goes to zero or it shoots up to 7000rpm , the drops again after a while to either correct tick over revs or keeps doing a dance from 0 revs to 7000rpm could this be the EXUP Value in the exhust sticking or could it be the EXUP server under the seat, as for the bike its ticking over great and pulls like a train , also i had the engine strpped and rebuilt last year and have only done 1500 miles since then so it couldent be a problem with this could it ? anybodys help in this matter would be appreciated Cheers Ray
