Morris said:Hi there, like this bike, nice work! I'm finishing my ''77 gs550. Little problem in the carburator/jet adjustment...
Really would like to know what you are running as pilot and main jet, hope you can help!
Wil post a pic if possible.
Greetings from Amsterdam
Morris said:Thanks for your help. I will check soon what I have in there now, I thought 110.
And yes those cheap air filters are a waste of money! The outer ones are k&n, and slightly shorter but I like the look of the filters on your bike more.
I'm also looking for a set of calipers from a SV650 ... I think a great improvement from the oem ones.
I'll keep you updated when it's running.
Mad Ratter said:Let me know if you go with the SV calipers and I can give you dimensions etc for the caliper mount plate,
Morris said:Made a deal for a set of calipers
Woul´d be really great if you can help me with the dimensions!
Do you perhaps have a drawing or...?
I also bought bigger main jets (110), i will try them asap.
Mad Ratter said:Here is a drawing of the caliper plate, the curve goes against the caliper and I think the spacers were made from ally and were 24mm thick by 24mm Dia. Picture too of the machined parts. Good luck, let me know how you get on.
Great!
As far as I know there are no lowering kits, but its dead easy, remove the damper rod and put a spacer behind the damper spring of whatever length you want to lower it by. I just used some old handlebar tube which was a perfect fit (7/8") and machined the ends square. You will have to remove the same amount from your spring ( I did it from the short rebound spring) unless you want serious preload! which with the GS, you will have to cut it (use a grinder cut-off wheel), you could try say 10mm at a time until you reach the tension you want, but you will have a hard job getting the fork nut back on, a friends help is always welcome.kwtnk said:Just read on Bike EXIF that you lowered the front fork by 50mm. Now I am curious how you did that. So far I couldn't find any fork lowering kits for the GS550. Do you have any tips or instructions for this upgrading?
Mad Ratter said:That looks a real nice build, high quality!!!
It looks like you have, pardon me for saying it, cheap Emgo type filters, not used them before but many have not had a great deal of success with them, best to get the real K&N's then you know its good!!! Get RC-0884, its a kit that includes 2x K&N part # 0880 and 2x RC-2620 so the outer ones are shorter and don't hit the frame.
I have a supertrapp muffler on mine, so all in all my settings will probably be different.
But I have 107.5 main jet, standard pilot jet, needle centre position, pilot air screw out 1 turn, pilot fuel screw in 1 turn for factory setting. Works great and runs sweet. Good luck and get those K&N's
Measure the OD with a vernier, then look on the K&N website, but be careful as the ones listed for my model DO NOT FIT properly and the ouside ones hit the frame, 52mm sounds mighty big, but then mine are completely different carbs, not sure that pods work well on those CV carbs either. I had to dig around the forums to eventually find the correct set. The GS Resources forum is good too as they are pretty much GS only.stevogs550 said:Hi there.
I've been struggling to find a set of those stubby K&N filters for my 1980 GS 550 with the Mikuni carbs. I think they have a 52mm OD. I don't suppose you know the K&N part number for those?! I've had to settle for foam Pipercross filters for now!
