Suzuki GS850 Chop TLC Part 4 - Carb Strip, Fault Finding & Cleaning Mikuni BS34SS

- Today I stripped the carbs to investigate the fuel problem, the inlet needle valves are mullered and need replacing. These are Mikuni BS34SS CV carbs.
I chucked some of the parts through the ultrasonic bath and blew out the various galleries, checked the diaphragm rubbers etc.
I had a complete nightmare getting the emulsion tubes back in which involved a lot of swearing, I've edited that bit out... ;)
Fantastic clip
I have a 1981 gs850g and since I’ve had it for over a year now I have a wee issue .
At 5000 rpm about 70 mph it bogs down then I have to feather the throttle back .
Idle is good and all ok up to 5000 rpm .
I removed the airfilter and it goes above 70 with no problem .
Just wondering if you could help please ?
Thanks

TBH I think you've answered your own question, sounds like your air filter is restricting the air flow at higher revs. What type is it? Stock/pod etc. Has it always had this problem?
If the filter is clean and unrestricted then you might need to go up a main jet size or two.
I've found shed fault finding is OK but for the best results a Dyno is the best way to go as it will give you a picture of how the induction and exhaust systems are working throughout the rev range.

Thanks for your info I really appreciate it .
Yes it’s a stock filter and it’s been like this since I got the bike .
I’ll try a new filter and try and get it booked in to check on a dyno .
I haven’t a clue how to change the jet sizes 😀
Filters a good bet mate, good luck.
