Are you sure its the ignition? The XT500 standard ignition is usually very reliable, I ran one of these in enduros back in 1978/9 (am still looking for WBJ227S) & never had any trouble with sparks. But the Mikuni carb caused poor starting especially if the bike was dropped and it became flooded. I replaced it with an Amal Mk2 and it was never any more problems. Maybe a modern carb suitably jetted would be in order. But first check all the usual things plug, points, connections etc. The ignition is direct from flywheel mag.

Before it was registered in UK it was in a barn in Spain for about fifteen years the previous owner had put new koni shocks exhaust and repainted the frame so it looks OK.

It does start so it's carburation that is the problem I am getting it cleaned at rexs speed shop Robertsbridge today plus the exhaust header was loose with no gasket in place and the manifold is perished and bleeding air (I had the same problem with a BMW F650) obviously not helping so I am looking to see if it's worth fitting electronic ignition and or converting to 12volt just to make it easier to start not used to kick starting bikes at my age.

Best of luck with it. Dont think you will get much help on here, there never seems to be anyone posting, I only came on board to see if I could trace my old XT (WBJ337S) as mentioned in previous post, but never got any replies. Strange as the XT500 (and SR500) are popular bikes so the forum should be very active. Although there are other XT500 forums they seem to be in USA and abroad. This XT500 club dont seem very active and only appear to meet once a year in Wales. Looks like it needs a 'kick start' and some new blood.

Looking at the dates on the previous posts I think you are right, good luck with your search for your old bike.

john m,just a bit of advice on your starting/carb concerns as I'm not sure how used you are to firing these things up.First off, never try to kick it up and get it to catch by blipping the throttle,this is gauranteed to wet the plug and is almost impossible from then on.Try this. from stone cold,petrol tap on and choke on,give 2 or 3 kicks, no start? choke off and kick again, it should fire.You can also turn the tickover screw in half a turn if you feel its 'trying to start'.


The XT carb is a reliable thing and certainly better than the OEM SR500 carb which has many internal diaphragms that can perish and give big problems [I'm a SR500 man]. Secondly if you conclude your old carb is worn out consider a Mikuni VM 34 aftermarket carb which are great value and bombproof once dialled in.I'm sure Marcus at Rexspeed will give you experienced advice.Generally speaking the XT/SR is easy to start once you have perfected your own technique.


Regards,

Andy
