FJR1300 2005 Gen I Vibration, Adjust Engine Balancers, Clean Throttle Body & Replace Seals. (PART 2)
Вставка
- Опубліковано 30 тра 2018
- When I bought the bike, I had vibration peeks at 3k, 4-4.5k rpm. I tried most of the common methods of fixing the problem (TBS, Unofficial TBS, Spray cleaning of Throttle Body, Torque the Engine Mounts, Plugs, Wires & Coils) to no avail.
I then adjusted the Front Engine Balancer and my 3k vibration was gone. 4k was less but still had another peek at 4.5k.
Since the Rear Engine Balancer was under the Throttle Body, I decided to do other maintenance at the same time.
This video is the complete how to for removing and complete cleaning the Throttle body, Seal replacement on the Injectors, doing the Engine Balancer adjustments and replacing the Water Seals on the Thermostat to Engine Water Pipe.
My theory of a loose Balancer is that the Balancer will vibrate in the space between the teeth and have a resonate frequency based on it's weight and speed in which it turns.
Model: FJR1300A 2005 Generation 1
Front Balancer Specifications: 1 Line clockwise from ~4 inch pounds counterclockwise position.
Rear Balancer Specifications: 2 Lines clockwise from ~4 inch pounds counterclockwise position.
WARNING: Do not turn clockwise beyond the specifications. This may in turn cause the balancer to skip teeth and require visual inspection of the alignment marks.
This video is in three parts:
Part 1 - Disassembly of Fairings, removal of Throttle Body, and adjustment of Engine Balancers.
• FJR1300 2005 Gen I Vib...
Part 2 - Cleaning and Lubing of Throttle Body.
• FJR1300 2005 Gen I Vib...
Part 3 - Installation of Throttle Body and reassembly of Bike, Impressions, Modifications.

Geez they look like a brand new set of Throttle bodies after youve cleaned them. Amazing. I would have used a de-greaser or solvent personally. but hey if it works for you and they look like that then fair play.
Good video, Mike. Very informative. Just curious... why didn't you clean and test the fuel injectors while you had them out?
I had replaced them with a flow matched set, a few months before the video. They are the same as a "1997 - 2000 Mitsubishi 2.4L Bosch CDH275" injector.
hey mike. I have another question: the engine balancers is something that has to be done once you remove the throttle boddy? I see you do some adjustments. I am removing my throttle body to clean it, but I am afraid to do those adjustments you just did on the video. can I proceed without touching the balancers? other question is, where did you get all the bushings , O rings to replace the old ones? thank you .
Hi the engine balancers are purely optional. They normally don't need adjustment. i was trying to do everything i could to help eliminate engine vibration. The injector seals came from oem suppliers like partzilla.com or mrcycles.com. if you use the cleaner in the video, only use enough powder to fully dissolve in the water. Blow air through all ports when finished.
@@mikesfjrcorner7129 Mike, you are a great man . Thank you very much.
awesome video Mike. how many hours did you spend doing all this? I ask because my bike is over 100,000 miles and now is making a noise by the engine side and I think it could be a leak somewhere down there. not sure if it is a bushing thing or what. I am sure is not a bearing because it is not a regular squeak.
Hello, Thank you.
Each part of the series was done in a day of about 6 hrs for 3 days. But that includes camera setup, shooting footage, retakes etc... I would say you could do it easily in 2 days.
Which side of the engine is the noise coming from? What does it sound like? Take a hose and hold one end up to your ear, then use the other end to search around the engine to isolate where the squeak is coming from.
@@mikesfjrcorner7129 Hi Mike. Sorry I didn't read the last part of your reply, it was hidden and I didn't click on the "read more" option. the side where the noise comes from is the right side area, and it sounds like when air escapes with a lot off pressure. like, pss, pss, pss . it is not a squeak like a bearing when it goes bad, it is just a very unique sound I would say. I am going to use the hose to see if I can find out where the noise is coming from. thank you. another question I have for you is that I bought the tool to do a throttle body sync, I followed all the instructions on how to assemble it and install it to do the test, I adjusted the valves # 1,2 and 4, but as I was doing it, I could not make valve #1 to line up with the rest of them, the first valve on the gauge was reading very low, and to make it go up to line up to the others I had to go clock wise, but I got to the limit of that screw and I couldn't go more. does that mean something is going on with the injectors, or something else in the engine ?
Well, I'm scratching my head! An air sound... I don't know. I'm guessing you should have a dealer that know's these engines look at it.
I'll just throw a few suggestions out there, as there is a lot happening on the right side of the engine.
Check that the plug's are tight and not leaking.
Check if the sound is coming from the Intake or Exhaust. Maybe there's a leak there.
If it was a random clicking, grinding noise towards the front, I would say, check the cam chain. But this is like an air sound.
Check the balancer's on the front and rear of the engine. Maybe they are making noise.
Check the reed valves for the PAIR System. During the exhaust Stroke there is a reed valve that closes to prevent exhaust gases from entering the intake, if this valve is leaking, maybe this could make a sound. The reed valves are located on top of the valve cover on the left and right side.
Check the compression on the cylinders since you could not get a correct sync. Maybe there's air pushed into the valve cover or crankcase which, is open to the front right side where the cam chain is. I would think this would make the engine not run right.
Also make sure the engine idle's smooth. If there is wire, coil or a plug problem, the clutch can make weird sounds as a misfire causes the springs and plates to chatter. However this would sound like a clanging sound. The clutch is located at the middle right side.
There is a pump located towards the back right side of the engine. Maybe that's making noise.
Also, Make sure your sync gauge is calibrated. Connect all gauges to one vacuum source through a 4 into 1 tee, and make sure they all read the same vacuum reading.
Again, get it checked out by a professional. As I'm only guessing without actually hearing it.
@@mikesfjrcorner7129 I appreciate you taking the time to read and reply to me. I took the bike to a motorcycle shop to check it out, but the mechanic couldn't diagnose anything. He told me that to find what was wrong with the bike, he would have to do it by hours and that was going to get expensive because he couldn't think where that noise was coming from. Although he mentioned that it could be that the exhaust could have a leak and that might be projecting the sound through the pipes, making it harder to identify.
I am going to follow your recommendation on checking the exhaust intake, plugs, balancers, and check if the gauges are calibrated. Again, thank you very much. You are very kind.
Did the balancing adjustment help?
Hello, In this video I did several things at the same time. So, collectively there was a difference. In hindsight, I'm leaning more towards the throttle body and injector cleaning, over the balancers. Although, there seemed to be a lower vibration that was eliminated. Hope this helps.
Mike,
I have my throttle bodies off and ready to go into the bath. I'm wondering where you got your injector seals and filters from. Please share. I'm having a terrible time finding them.
Thanks
partzilla.com or mrcycles.com OEM parts.
@@mikesfjrcorner7129 thanks Mike. So once I put everything back together the left turn signal won't turn off... any clues why?
I'll take a look at the schematics tomorrow to see if I can itentify where or which connector to check. Likely, it's a connector or a star ground in the bundle of wires that's along the front of the frame under the tank that may have gotten either shorted or broken.
@@mikesfjrcorner7129 thanks.
Look for a short to +12v. Here's the schematic. drive.google.com/open?id=11krb1Sv_QQIDItSvbCNe6zUGGMPnOE7-
I4 engines are not balanced by nature, the balancer only reduce the vibration to certain level, no matter how you adjust it, it will vibrate. I6 engine is perfectly balanced.
