For more accuracy take the measurements for each valve when the cam lobe is pointing away 180 degrees from the cam bucket/follower. Although the manual says do it only in 2 positions, you aren't getting the true clearance because the cam is often not perfectly round but slightly oval. At least take measurements in both positions to find if there is a difference. Often at 180 degrees (pointing directly away you will actually get less clearance. It is possible to be within spec in the manuals position and be too tight when the cam is pointing directly away.
At 8:31. Is this step a MUST-DO? I did valve clearance checks on my 1990 GS500 (80,600km) a month ago all valves were in spec. However, I don't think I did this step of "re-aligning" the engine??? How important is it to do this part? Thanks!
Thanx for the vid...I been riding my GS500 a bit harder lately and it developed a muffled sound on accel...then started to knock 1 morning, increasing & I checked oil level..nearly out & now has a shocking knock at idle, decreasing as revs are increased...any ideas??...I`ll have to strip it down but just not sure where to look first :(
My Suzuki service manual say's _not_ to use a magnet to remove the shims; stating that the hardened steel shim material could become magnetized, which might attract debris or even pop out of the bucket. I use a pair of tweezers (Zircon encrusted optional), which is a bit more challenging, but may be safer. Please advise. OK on the magnet or no? Thanks.
Guessing you are in Baltimore. You work at a shop? What would you charge to adjust my 92 GS500E valves? Just picked up this bike and it stalls out when coming to a shop. Carbs are clean, heard valve adjustment could be the issue.
I have recently bought a 1992 gs 500 it has 25K mile's it has great compression but is hard to start back fire's and when I do get it running the left side carburetor shoot's out little stream's of gas out of a little hole where the air intake port is . Is this because I need to rebuild the top end or would it be as simple for me to just adjust the valve's?
I had a GS500 and it was ok upto about 90mph then it would just hit a brick wall. I suspect the shims needed doing. I like this method which doesn't involve removing the camshafts. To do the shims on my ZZR600, you have to remove the camshafts.
It's the fuel control valve. Put it on "pri" under high load and check if the problem is gone. Vacuum operated and there's almost no vacuum under wide open throttle and the diaphragm gets old as well. On pri you put the system on priming and thereby override the system but never forget to put it back on normal afterwards. Common problem and try it first
2018 but still one of the best videos for valve adjust. Thank you!
2020
2021 and this video still holds strong 💪
2022
2023 still pushing the gs500
I check my GS today and this tutorial help me , great video and thank you
thanks! this helped a lot even in 2020

Me encanta esta motocicleta y el entender su funcionamiento es bueno, gracias por hacer estos videos y espero hagan muchos mas…..Gracias

great job, very informative. whats a good source to order parts for 1970s to 80s bikes??? building a racer now out of a GS 400.
Thanks this video is very clear!
Does there need to be oil in the engine to do this? I have already drained mine and my engine is out because I am about to tear it apart.

No magnets......
Good to know, thank you for the advice

at 3:00 could that be a method of crank starting?
dose this apply to all models I have a 1981 gs550L
when should I check valves my bike has 40.000 km or 25.000 miles.
2:10 ..."only turn the engine clockwise!!" Okay...but why? and if you did...what do you do to fix "it"...asking for a friend. hahahaha
Una pregunta.. seria el mismo procedimiento para una zusuki 450gs L?? De antemano gracias y saludos desde estado de México
El mismo, básicamente es el mismo motor
Thanks for sharing this video, next time I'm going to check the valves by myself.
... + girl please marry me! Lol
Muito bom👍
...i love you so much special girl...
Baltimoregd just uploaded a video can you check it out txs
She's a cute girl :)
Hola nena ,el motor se gira antihorario ,...
Se gira en el horario! no confundir a la gente
