Boss,
Thanks mate, I appreciate it.
The spark plugs had a little fouling and all looked the same, some oil. They are new and NGK 10's, maybe need new ones and go champion?
Cant believe you can get your revs that low. At 900 mine want to die, would you put this to timing?
I have sync the carbs, there wasn't much there to do really. I changed the position of the cam roller follower as it was heavily worn one side to being flat. Upside down trick.
Ill check Joes forum.
Being this is a low revs issue, I would assume then I don't need a timing light to do the bottom end then.
Also when you say bottom one is this the idler screw? You nailed it in saying bring the idle up enough so I don't conk when changing to gear, as that's the primary issue.
I wouldnt bother about changing spark plugs, unless you have spare coin to chase up a 50/50 chance.
Id put your 900 solely down to the thermostats being out. I need to idle mine up around that until its warm then i put down the warm up idle lever and she drops right down .
Correct you dont need a timing light on the bottom end as its all done by as low as you can get it before conking out (when shes warmed up!)
I would be a bit wary about high your top end is, if you can do with not hitting 90kph id adjust the max timing advance in a bit until you can make sure using Joe Reeves method that you arent sorching your pistons.
Also do check your steering system as if something gives way at that speed its really serious. I always wear the lanyard line for that reason (it kills the ignition instantly). I know down here in Aus and NZ we havent had any high profile recent tragedies but in the Uk and elsewhere many people have being maimed/killed by steering system failure.
Not wanting to sound like a stick in the mud, but when ive check all mine over and wear the lanyard line then im definitely in the best head space when out there
