Hi guys,


Today I have pulled out the carbies cuz the bike was not idling good ( I think problem is clogged jets).


When I took them a part I have found a kind of caramel varnish on cylinder heads - where booties attach- and also I have seen it on the "butterflies" - the ones you tune when you sync carbs-.


I have seen through plugs that bike is running rich, so now Im going to tune air-fuel mixture. 2,5 turns would be ok?


Do you think this varnish is just because of bike running rich? or I might consider gas quality, rust in tank, or bike sitting for some time?


Help would be appreciated.


UPDATE: I have remembered that last time I have synced carbs I did it with a home made device, that I built with hoses and oil inside. Some of that oil was sucked by the carbs and later burnt by exhaust.
I have realized "caramel varnish" could be oil, and I hope is just from carb sync.


Anyways, any help would be appreciated.

Pictures, in this situation, would really help.

 

Hi Cornrice,


Thank you for your reply.


I have already cleaned everything. I made the mistake on not taking pictures before. I took some pics now, where with a little imagination you can figure out how was that "varnish", as there is some still left.


Regarding jets, they were quite clogged so I think would start idling ok.


By the way, don't you know a fuel stabilizer or something I can use to avoid jets being clogged due to bike not running for some days?


Cheers mate,

Wow, that's a lot of oil build up on those valves and ports. How's your oil consumption?

 

Hi,

Bike has been sitting for some time, also has been leaking some oil through a seal that you have helped me to identify on diagrams to order it

Even though, oil level looks fine.

 

Well, if its been sitting and you haven't been putting a lot of miles on it, you won't notice oil consumption.

Even with a small leak - oil looks like its a lot bigger volume when its on the ground than it really is.
