Does it matter if I leave the plugs out or put them back in?
I checked valve clearances before I got it running and replaced shims as needed. I am going to recheck shims soon. I know one is out of spec. I...
I have an 81 xj550 seca that I'm "fixing up" after being put away in a garage for 7 years. I swapped out the airbox because of missing parts and...
I've also been having this same issue with my 81 XJ550. Replaced all of the seals in the carburetor except the mixture screws which I could not...
Well I re-jetted the carbs to 120 mains and 37.5 pilots and still the hanging throttle issue persists.. choke is closed, throttle cable is smooth...
Well I currently have 2 k&n open air filters on my stock mikuni carbs(one for left two carbs and one for right two, it looks sweet). Like I posted...
I'm going to be running a custom 4-1 exhaust eventually anyway so I guess its time to go jet crazy! @chacal I assume you have a great selection...
Swapped out the resistor plugs for non-resistor plugs and it fired up. Now, obviously my carbs haven't been tuned yet but when it came on it...
@chacal that's a great explanation! Thank you. I'm going to try the non-resistor plugs tomorrow and see what happens
My Clymer confirms that the OEM spark plug end caps are 10k ohms. I'm just not sure if it would cause any issues using 5k ohm caps with...
Just tested. I was getting 11 volts while cranking with this superstart ext9 AGM battery.
I am going to test this battery tonight while starting. The last battery I had in it would drop to around 9 volts when starting so I replaced it...
The OEM end caps are 10k ohm, aftermarket NGK end caps are 5k ohm. I have 5k ohm end caps and 5k ohm plugs which brings it back to OEM 10k ohms.
I have an 81 XJ550 Seca that I have fighting to make run for a while now. I cleaned and soaked the carbs and replaced the seals for the throttle...
I'm not sure if anyone is still sharing a pdf of the xj550 repair manual but I could really use one as well..
Side question. Is there a specific way to remove idle mixture screws? I tried backing one all the way out but it didn’t come out, it just kept...
Rechecked resistance through coils today and found out my caps are what need to be replaced. A full tear down and soak of carbs is in the works...
Update: I took the carbs out and the idle jets were completely stopped up again so I'm thinking I'll need to clean out the tank soon. I cleaned...
Alright, I guess i'll dive into this next week and just finally take my time and clean them thoroughly so I don't have to remove them again! Thank...
What pieces should I remove before soaking? Obviously the diaphragm but what about the float seat etc? Also, how long to soak? I’ve looked...
Checking the float height isn't something I have tried doing before. I'll need to do some research to figure that out. I did not take the carbs...
So just some background, I bought an 81 xj550 seca that had been sitting in a garage for 5 years and would not start. Naturally the first thing I...
Joshua, are you still going to get some pictures of the air box cover?
Thank you so much
This may be very off topic but it sounds like you have all original air box? I am currently rebuilding a 1981 550 Seca and unfortunately I am...
I have decided to take on the task of making my own cover. May even try to 3d print one. The only problem is I can't seem to find a good picture...
What type of oil is recommended for the 1981 XJ550 Seca? I bought this bike out of a garage where it had been sitting for 5 years and am slowly...
I may actually end up making my own but I’d rather not.. Also who is Chacal?
This is pretty old but I have just purchased a 1981 XJ550 Seca and I discovered today that the air filter and filter cover is missing... may be...
