Buell XB12 Hot Hot

[LeFox]

dozer, aslong as your fun runs when shutting the engine down, shows the it's still getting signals to go on.

i need to ride more than an hour at a lower speed (less cooling) to get my fan to work.

Hmm...even lower speed with less rpm's...seems like it would cool better. Lower speeds with higher rpms = engine gets hotter. What the hell, its running fine, im not gonna worry [smirk] It just seemed like something wasnt right. I've been using synthetic since about 600 miles on the ODO. Now im at 3200ish, and changed the dam oil 3 times already [mad], once with Mobil1 v-twin and 2x with Royal Purple Syn. I think maybe its a combination of the bike breaking in and the oil doin its job.

LeFox is absolutely right here. If the fan kicks on after you shut off the bike just like mine does that means the oil is keeping the motor cool enough. My bike does the same thing when I shut it off the fan kicks on and I mean as soon as I shut it off. That is ok it is doing it's job correctly there is no burnt out relay or antyhing. If the relay was burnt out the fan wouldn't come on at all.

If the relay was burnt out the fan wouldn't come on at all.

Yeah figured that...but didnt know if there was a temp sensor during riding, or thought that maybe the fan just automatically comes on after riding by default.

I have an 08 Firebolt, just picked it up month and a half ago. 1k service last week, I had blew two sparkplugs and had to take it in on one cylinder. I went out and started it this morning and came back out about 5 mins later and my pipes at the top were red hot. Couldnt believe it, idle and throttle responce seemed good. Any ideas or is this normal for 5 mins of idle time on these bikes. Thanks alot guys

 

[LeFox]

it's not good to let your bike just idle like that...you can burn your valves, plugs, etc.

could be that your engine is running a bit on the lean side, but that's hard to say with the info.

When I blew the orignal plugs the service guy said that i should let it warm up a bit before running it to avoid blowing more plugs, but ya im pretty sure the bike is running lean, top of my pipes have started blueing slightly. Any advice. Appreciate everything guys.

Edit: oh btw, the service guy also said the 07, 08 firebolts blow plugs fairly often. Any have any input on that seemed a bit fishy.

 

[LeFox]

a good way to let the engine warmup is:

- get gear on except for gloves & helmet.
- start the bike and let it idle, no throttle during startup or warmup
- put on helmet & gloves
- start riding with smooth, soft accelerations and no more than 3500rpm for about 10 minutes.

after that you can do what you want.

got some pics of your headers?

if your service guy says the firebolts plow plugs ofter he should go back and service those engines, cause that's not normal

And don't forget to put your lid and gloves on while sitting on the bike.

I've heard bad tales about leaving Buell's ticking over on their sidestand...

What do you mean by "bad tales"? You've heard of it walking off the sidestand? Sounds like bad tales of poor clutch adjustment to me.

was mostly a tuber problem...

but on a fully loaded uly is would also recommend sitting on it. the newer sidestand is revised...

I've read that pre-'07 bikes had a different kickstand bolt. If the bike was parked on a grade, they would fall sometimes. I back my bike up to put it on the kickstand and leave it in gear just to be a little safer. It would make since that our bikes, as much vibration as they produce, could fall while idling. Especially a pre-07...

oops, sorry. Didn't realize this was such an old post. *Disregard*
