Hello all. A fuel leak, proper gushing, after storage has prompted the carb rebuild I've long suspected was coming (partly because the secondary air filter element was found to have disintegrated when I got the bike). Thanks to Adam Frymoyer's guide, removal was strait forward. Upon looking down into each of the intakes on the engine I noticed allot of carbon deposits on top of at least one pair of valves. All had some, but one set had a little pile (3-4mm lump). I'm aware that the bike is probably miss firing and is under powered. I checked the resistance on the coils, and HT leads (with and without caps), the caps on the left bank are more than double the resistance they should be, as a pair, but without caps are in spec. Obviously I need to maintain/replace the spark plug caps on this side. My questions, to any one willing to advise, is:
The bike has been run for a few thousand km with a misfire and noticeable repeated fouling on the plugs of one bank. I'm over hauling the carbs....but do I need to be concerned about the amount of carbon that will be present in the cylinders?
Can excessive carbon damage the piston rings/valve seats?
Once the carb is sorted should I run a couple of tanks of fuel additive?
It's probably obvious to many of you that I've limited experience in deep maintenance like this. I enjoy it and prefer to do what I can myself, not least because I hate shelling out for often poor work by mechanics. I'll be going further than Adams guide because the fuel leak is down to a failed O ring on the fuel tube, necessitating a total strip down and rebuild...so wish me luck.
