February 15, 20215 yr I have a new repsol, 4 hours done on it, thought a little hard to start, few extra kicks,was out on it yesterday finished up and brought it home washed and cleaned it , now won’t start,I changed spark plug and have a spark, turn over is turned up ,throttle body connection clean , any ideas what could be up , any help much appreciated
February 15, 20215 yr The first thing to try is the easiest, reset the ECU (see "Engine start" in text snipped from manual). If it doesn't start in 3-4 kicks after that, the next thing is turn up the idle 1/2 turn CCW with the idle air screw. Doing another ECU reset doesn't hurt. If it starts, you can readjust idle following the manual after running for a while.
February 15, 20215 yr Are you a previous Montesa owner? If not you may have the wrist connected to knee syndrome where you crack the throttle on every time you kick start the bike. They like to be started on zero throttle.
February 15, 20215 yr Author Yes I have had 4rts for a while now,it’s more serious than that I’m afraid
February 16, 20215 yr Maybe check a few of the list below? is the throttle cable tight or snagged in some way? (will cause it to be like cracking the throttle open on starting and not run) Wire to the fuel pump connection issues will prevented a 4RT from starting. (check its all plugged in well) A bad kill switch can cause starting issues. (disconnect it to check) Some other connector loose? (there are a few to check) Grounding wires can cause issues. That is a few I can think of worth a look and if I can think of anything else I will chime in on a new post.
February 16, 20215 yr It could be the C19 setting? They won't run during lockdown. It protect the NHS A and E.

February 16, 20215 yr Hi You have all the usual suspects above. Here's a few more simple ones:- 1) Have you made any changes? Simple stuff that may effect connections etc. Like taking the headlight off.... If so retrace 2) How fresh is the fuel? 3) Did the plug you changed come from a reliable source? 4) Give the bank angle sensor a knock, make sure its not stuck. Cheers
February 16, 20215 yr Given it’s so new I’m sure Honda/Montesa dealer should sort things out for you. Best of luck.
