Title: stalling out at 60mph (SOLVED)
Post by wickedbiker on 05/07/14 at 16:42:49

Hey again, I am sure glad I have this place because ever since I bought this bike and fix one thing, I'm right there with something else to fix right after. Guess the good thing is I am down to one thing after another as before it was multiple issues. Anyway, I thought I was having a clutch slip issue fixed that and now everything runs perfectly right up until I reach 60mph at that point the bike will begin to hesitate and at between 65-70mph it will stall out completely until I get back to 60 & below. It reminds me of having a governer. Here's the scoop I have the stock BS carb wide open shorty mufflerand screen air filter (temporary to make sure the cone wasn't my other issue)
Carb has 2 washers instead of the white spacer and 55 pilot and 155 main jets any ideas?

how many turns out on the mixture screw? You might be running too rich..

Try turning the screw out only 2 turns, maybe 1.5 turns...


Try running on prime and see if that helps (your petcock might be faulty)

You can check your pet,... it could be giving trouble...
... but, you will never run well, with a screen and a open muffler...

Get a real filter, and get a chamber baffled muffler... you will see a huge boost in power...

Loud is not fast...

I forgot to mention I just added the raptor petcock and as I said I have a real air filter but I was testing it cause its the cheap Chinese blocker pod. The muffler didn't fit with the baffle so I had no choice, although it has a nice deep Harley tone now and I like it not to mention when you live here in Florida where 75% of the pop is geriatric loud is alive. I had an old woman watch me pull right up to her at 55mph before she decided to go. My wife and kids where in the car behind me watching me almost slide under a boat and truck as I'm power sliding down the red @ 55. So you mean to tell me with a straight pipe on these things they die out at 65?
I must be missing something, I know one thing I am about to give up on this bike and sell it or trade it for something else cause for the past few months since I got it I have wrenched it twice as Mich as I have rode it. This thing is getting rediculus. I think even you guys are getting sick of helping me.

Naw, you're just getting into the good stuff. All the piddly crap so far has been just that, piddly crap.

Florida is sea level or below. 155/55 is too fat, you're actually choking it out with too much fuel on the top end. Stock is far too lean for sea level, but perfect for people above 4000' elevation. You forgot to factor in how much denser sea level Dixie humid air is. Your 155/55 is acting like a 185 or bigger main.

I used to live a block and a half off the beach in Long Beach MS. You need a 152.5 over 50, or a 150 over 52.5, haven't lived on the Gulf since 7/99, forget exactly which combo it was, but leaning towards 150 over 52.5...

Pretty sure I have a 150/50 in my 03 right now. I could use a bigger main, tops out at 72mph, but, my 14EEE logging boots do act as brakes, so do the saddlebags and windshield...

I was thinking that was the issue I'll try those combos out tonight, thanks

And the petcock said it was a raptor Yamaha 660 petcock I ordered it on eBay from zoom zoom parts in Michigan. It seems to be working a hell of a lot better than the one that was on there..

Looks the same to me but those Chinese knockoffs do sometimes

I'm assuming this is the un -orange-urinal

I'm not going to lie though, I did pay $7 shipped for it... :P

If this helps, I'm in FL (sea level) and my factory supplied jets worked fine before and after removing the white spacer..

I did run on prime after my petcock started displaying symptoms like you described (ran fine on prime)

OK did I say I was fet up with this bike? I think what I meant to say is I love this little bat out of hell!!!! You were right on the money I swapped out the main for the 152.5 and bingo bango I got to 70.... 75....80.... the bike was saying "is that all you got???" But I didn't want to push my luck on us 19 so I was happy with that. Thanks guys bike is ultimately running perfect all the way up the throttle. :D

Great to hear your problem was fixed.  Don't stop tuning; see if she's got more!

FWIW, that petcock definitely looks like a Chinese copy.  Genuine Yammer-Hammer pet-rocks have only 1 lip on the outlet nipple.  They also have a stamp at the top edge on the same side as the face.  See attached pictures for references.

You may find that your chinese copy works okay for a while.  Ride it till it dies - that could take some time.

I just checked my raptor 660 petcock, which I just received, to see if it is a copy.  It came in a Yamaha box with part no. 5LP-24500-01.  It has the single nipple and it has a stamp in the same place as your H14, but it says b3N.

Hell $7 shipped I don't even know how they can afford to make and sell these for this price it was actually pretty well made it had to have been at the least $3 to ship.
So in reality this part was cheaper than any chinese part I have ever seen and I got it faster too LOL!!! LMFAO!!!

Nope.....That is a chinese copy.  The original has a brass tube with an expanded raised area - not a machined nipple with two ridges.  The original is also a full 8mm(5/16")....the copy is slightly smaller and the original fuel hose is too big and leaks....unless you install a screw clamp.

Title: Re: stalling out at 60mph (SOLVED)
Post by wickedbiker on 05/09/14 at 08:41:08

Thats true the gas outlet is a lot smaller. I had to use a screw clamp for it. But all in all it hasnt been all that bad it is working pretty darn good so far so no complaints yet. I'll update here if otherwise, to let you all know. The main thing for me is it fixed all my oem petocck issues and the gas tank is a hell of a lot easier to get off darn thing use to be a complete struggle now its disconnect and pull right off, I love it!!!

Quick question to the experienced guys, I can't seem to remember to turn the petcock off to save my life and I am yet to do it even 1 time. I leave it on all day and night sometimes if I get lucky and remember I will go back out and turn it of. I haven't had any issues or leaking or anything like that, but my question is whats going to happen or is happening as a result, perhaps if its bad enough it might actually make me remember more to turn the darn thing off.

Post by WD on 05/09/14 at 08:50:14

Get one of those double belt clip stretchy key rings. Clip one end to your keys, the other to the fuel line at the petcock... Just a training aid, should take about 3 days until you remember on your own.

Post by Dave on 05/09/14 at 09:21:27

I initially got in the habit each time I hit the end of my driveway.  Now I shut it off on the way home when I turn the corner at an intersection 1/2 mile from my house.  As I reach the end of my driveway the bike starts to stumble.....my bike now is parked with little fuel in the carb.

Thanks Dave, that is disappointing.  I would have not known, I really dislike that feeling of getting swindled.   :(

I noticed I still wasn't get quite the power I should even though the bike was running normal now I realized I needed to got to the 52.5 pilot as well. I thought about what you said about it being more because of sea level. The bike is running top notch now. So for anyone in Tampa Bay I am running wide open pipe and carb with 152.5 main and 52.5 pilot. Thanks again WD you da man

How many turns out is air mixture screw from the factory?

Less than 1 usually.

Alright I'll give it a shot, I'm thinking there is way too much air because all I have is a screen over the carb right now

I did this and it did help a great deal I acctually had to turn it out 1/2 to 1 turn and up the throttle screw and the popping is still there but a heck of a lot less of it.
