jimmyl Posted November 18, 2013 Report Share Posted November 18, 2013 Funny mine did similar Sunday. I think I inadvertently stalled just as I kick started it or didn't start it properly. Fired once or twice then struggled with it as you described. I have winter plug in mine which seems to improve things. Also make sure in neutral and stopped on kill button. If you find anything else let me know! Quote Link to comment Share on other sites More sharing options...
jrsunt Posted November 18, 2013 Report Share Posted November 18, 2013 I had a similar issue on my 06 bike, turned out the valvues were running too tight when the engine was hot. It started fine when cold tho. Might be worth checking them. 1 Quote Link to comment Share on other sites More sharing options...

oz thumper Posted November 19, 2013 Report Share Posted November 19, 2013 I had a similar issue on my 06 bike, turned out the valvues were running too tight when the engine was hot. It started fine when cold tho. Might be worth checking them. I was going to add the same advice as John, Had exactly same experience with tight valves, ashamed to say that I had not checked them for a year or more as they so rarely change, however picked up the exhaust valves were about 0.03 tight when I checked them, adjusted and an immediate improvement in hot starting and never looked back since.

scraggydog64 Posted November 19, 2013 Report Share Posted November 19, 2013 I had an 05 4RT that i gave to my lad and never had these problems. We still have the bike. I bought a nearly new 09 (It had only done 1 trial.) and have the same problems as you. The bike has done this from day one. I often have to open the throttle and kick to remap before it will start. I have never checked the valve clearances and the bike has done so little they should not need adjustment. I have asked a few people who have owned 4RTs and the newer ones often have this problem. Think i might be getting the feeler gauges out. Quote Link to comment Share on other sites More sharing options...

warby beta Posted November 19, 2013 Report Share Posted November 19, 2013 As above my valves were mega tight and it was a hooer to start. Reset the gaps and away she went, never a problem since. This was 3 rides after pidcocks had 280'd it. Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted November 19, 2013 Report Share Posted November 19, 2013 I find that if I stall my '05, it can be difficult to start after. I also had a problem recently with the throttle cable pulling out of the fitting on the hand throttle just enough to crack the throttle open even when I held the throttle in the closed position. As you know, if the throttle is open at all, the bike will not start. Check that the cable end is fully seated. Quote Link to comment Share on other sites More sharing options...
