Well recently being trying to track down rough running on the Sprint... I am making progress but not cured yet ??
But a short list of the do's & don'ts of the maintenance I have done so far...
Don't...brake off one of the mounting lugs for the body work before you have even done anything constructive !
Do...repair broken mounting lugs with Araldite and hope it works ?
Don't...break off the fuel selector knob even though you have read a million times on this forum "they all break"
Don't...then phone your local dealer for a replacement and have them let you know it is not available on it's own you must purchase the whole fuel tap assembly at £66 quid (probably plus vat too!!)
Do...keep hold of your broken selector knob when the break including the bit that broke off to save you from running around in a mild panic trying to find the bits in the garden !!!
Do...repair your fuel selector with Araldite..also fill the void in the rear of the knob like you should have done ages ago when reading about how they "all break" !!
Don't forget when you have the carbs off for a clean to also pull the fuel filters at the hose unions on the carbs rather than thinking a quick spray up with carb cleaner will do..
Do...then set these aside and fit inline fuel filters.
Don't...twist and force you new fuel filter into the fuel line so much that it looks like this
and won't pass any fuel..as you will only know this when the bike is fully assembled and your miles from home :-/
Do...flush your rusty fuel tank and seal it
Don't...do this when you have a full tank of fuel which you have to drain...double don't.. syphon it out as you WILL get a full gob of unleaded fuel complete with RedX fuel treatment !!! bit tart slightly cheeky but full boded :-0
& finally...
Do...if you have a faulty HT lead check all the others carefully as another may need replacing..this will allow you to cure a potential problem further down the line that may manifest itself as fuel related and so overt a LOT of ham fisted spannering....
Sheeesh ever had one of those days !!!!!
