Not starting after chanigng plugs
« on: March 29, 2020, 04:12:24 PM »
I changed my plugs and air filter yesterday. On starting up the revs would shoot to about 2500 then drop to 1200. It would do this every time. I left the engine running for 15 mins and allowed to cool before each start.
This morning I chose to strip it all down again to see if I had missed anything. Hose from the airbox was off.
Rebuilt it and now it will not start. Turns over easily but not running.
What have I done wrong?

Are you sure the coils are in their correct places?

Double check the spark plug gap and also the coils are a nice snug fit.

have you got an engine management light lit up on the dashboard ? if so you probably have a plug off somewhere under or around the air box.

if you haven't got a engine management light showing, just make sure the kill switch is set in the run position, i know it sounds simple, but its easy to hit by accident.

you say it turns over, but wont fire, make sure all the coils are pressed well down on the plugs, and recheck every connection under the tank.

Likely an elec connection under tank.

Got back to this today. Stripped her down checked all the connections and fitted a starter motor from a 675 street triple.
Rebuilt her, double checking everything on the way.
Tank on, plastics on, ignition on, fired up first turn.
Massive difference in starter power.

I'm glad that your problem is fixed, but........

you said it was cranking fine in the original post so why did you go the [pretty significant cost and] trouble of changing the starter motor?
It sounds like a lot of work to fix what was probably a loose connection
