But once the bike is warm it will stutter as soon as you give it full throttle? Are you using choke when it's cold? If not put some choke on when its cold and then give it full throttle. If it stutters, then this may point towards over fuelling or not enough air as the problem when the engine is up to temperature. Also you can test this again by seeing if putting choke on when the bike is hot makes the stutter worse. Let us know what happens when you try this. Cheers.Information overload at the moment. But all ideas gratefully received. I am going to try it again tomorrow before I go any further. I normally start the bike on choke and reduce it over a couple of minutes. Then ride off with no choke. I'm sure when I rode it the other day, initially the bike seemed to be ok but when I started to give it the beans, that is when it started to bog down.
Plan of attack tomorrow weather permitting.
1. Try riding it gently all the time see if it behaves
2. Ride hard and try and get it to stutter. If it does, try putting the choke on to see if it makes any difference.
3. If it does stutter I'm going to replace the fuel filter and check out the No4 Diaphragm. If that doesn't help.
5.Set fire to her. Only kidding :b
