Hi all,
I have looked EVERYWHERE online for an answer to why my bike is doing what it is, and have had very little luck, so i turn to this forum in the hope that someone can shed some light on what may be happening!
I own a GS1100GK which i bought in average condition and have cleaned up quite a bit, I am having alot of fun modifying it and making it my own, although i've owned 9 different bikes in my lifetime, this is my first real delve into the mechanics side of them. >
I've come across a problem with it having trouble accelerating under load.
The bike will idle and rev at a standstill without trouble, but as soon as it's put on the road and given more than half a throttle (or put under heavy load) the bike just splutters, or bogs down. It doesn't die, it just refuses to accelerate further, and I hear pops from the exhaust, not backfires, just pops. The engine DOES propel the bike forward, but it's certainly not fast, and no where near as quick to accelerate as it should be.
So far I have taken the carbs apart. and cleaned every orifice according to the GS RESOURCES carb cleaning tutorial, I found a rebuild kit and replaced the main, air and pilot jets, same size as original, just new. I have had a mechanic friend compression test it and it tests fine. I have swapped the coils over with a GS650G set, the problem does not alter at all. I have carefully checked float levels and set them to 23mm complying with the maintenance manual I have.
Any information on where to check next would be fantastic, i'm pulling my hair out here, its frustrating just not knowing where to go next.
As part two of my question, (and this may be one of the problems, i dont know) Upon cleaning the carbies, I found an orifice that i have no idea what it does, it seems to be blocked up with what looks almost like solid superglue, which i guess could be varnish, i have linked a photo below with the subject circled in red, I can take a photo later of the actual part if required. any info on that would be great too! Possibly this being blocked has something to do with my issues? >
Thankyou for any information you can give me, i realize this is quite long but I've nowhere else to turn to!
