     Loloxb12r |
ive had my xb12r for 2 years now, and always just took it to the shop to do the plugs, but since this thing fouls plugs soooooo much, id rather do it myself!! It really cant be that hard. anyone got some directions or help for me?? | ||

First of all, the XB should NEVER foul a spark plug. I change mine after 10,000 miles and they look brand new when they come out. Your spark plugs should NOT fail in service. Is it possible that either your idle speed is set too low, or that you have a brother in law twisting the throttle incessantly while the bike is not in motion? Either of these conditions can cause a lot of unburned fuel to accumulate. Remember: 1050 RPM is idle speed, and TWIST NOT THE THROTTLE except when under way. As far as the infrequent plug service, the front may be accessed very easily with a straight box end wrench, after removing the intake air scoop ( 3 screws, T-27) The rear spark plug is not too tough to access, but the air box needs to come off first, probably about time to service the air filter by now anyway, sand and debris accumulates up there anyway, so it really needs to be checked/cleaned about every 3 or 4 thousand miles. so when airbox is off, use a deep 5/8 socket, u- joint, and about 10 or 12 inch extension to remove plug. I use a foot length of fuel hose to re-insert the new plug, kind of like a skinny flexible hand, just to get the threads started. seems like a bitch the first time, but really not all that bad. | ||

Thanks for your help bud!! I let my bike warm up plenty but even the guys at harley said these things kill plugs left n right, but i know they just want the money ne ways!! So excessive reving when the bike is not in motion is bad then correct?? i should give it more of a slow twist is what ur sayin?? ill prolly begin this lil project tonight!! | ||

ok i got the airbox/filter/and the black plastic peice it all sits on or whatever! i still cant get into the top of the motor where these plugs would be, im guessin!! hmmmmm maybe ill just go buy one of these so called 50$ service manuals or something! | ||

Outstanding manual yes. Just checked my plugs Sat. I just removed and started plug with the 5/8 socket,universal and extension Follow fullpower's advice. Works like a charm | ||

Again, I am into the conversation late. Hopefully this will help someone in the future that reads this thread. If you are the only owner of your bike and take care of it then most likely your XB series bike will not foul plugs that often, if at all. "However," with that being said I see a LOT of XB series Buells that have fouled plugs. About how many you say. A guess would be 7 out of 10 bikes I see need to have the plugs cleaned/changed because they are fouled. Not sure what the previous owners are doing but that has been my experience. Now onto the plug changing. You can do both plugs in about 10-15 minutes. Front plug I don't think anyone needs any pointers on. It is rather self explanatory once you see it. For the rear you don't need to remove anything from the bike except the seat. Yes, that's it. From there you need a long set of needle nose pliers where the tip is bent at about a 45 degree angle. Insert the pliers through the little access hole to pull the boot off the plug. Then take your spark plug socket with a wobble extension and feed it through the access hole again. Remove spark plug and reinstall in the same manner. It's as simple as that. It takes me roughly 10 minutes to R&R a set of plugs. HTH | ||

Be careful on the back plug! I was very stupid and overzealous and stripped my head when pulling the plug out. It cost me $900 after that JUST to CHANGE that PLUG! I have since done my plugs many times without any problems I now take my time and use a wobbel/ swivel adapter I also read somewhere here, to use some gas line to hold the plug while you install it. It works GREAT! | ||
