No power above 5-6k RPM?

[Tronspeed3]

Got it mostly back together last night! After battling with the air box for an hour (stupid rubber boots), I put the fuel line on the tank and Dammit! a hole in the hose at the tank petcock. Will be up a running tonight hopefully!

Any suggestions on air/fuel mix screw settings for the #40 pilot and stock main jet? I'll probably start with 2 turns out.

If the bike is completely stock, most people run at 2.5-3.5 turns out. Might be a good idea to start at 3? Dunno, I know they seem to differ sometimes - I know mine refused to run at 2 turns.

Then again, it might be better to just leave it alone for now. Only reason I suggested the #40 jets is because it's an easy upgrade and it's worth doing, especially if you're going to mess with the carbs anyway.

#40 pilot jets surely isn't going to make the bike run worse.

Got it running again and it idles real nice now without the choke on! Then I decided to change the oil and filter ... The acorn nuts and studs are stripped out and I cant get the filter cover back on! Does anyone have a place to buy them from ?

Never mind,I hope 6mm X 1in is correct! an new acorn nuts! stupid tiny bolts !!!

Update: picked up exact duplicate studs from true value along with some regular nuts and washers to fix the the stripping issue... i'll just torque them to 60 IN-LB and be done with it hopefully the seal doesn't roll out of the groove on me this time and I cut it to shreds!

[Tronspeed3]

Ok fixed the stripped out studs and got it running and it still really struggles to rev past 6k "with me on it" but sitting on the stand in neutral it'll rev right to 11k no problem... however I think I might have found the issue, when sitting on the bike if I pull the left spark plug wire off the motor doesn't miss a beat. However if I put the left plug wire back on and remove the right side plug wire it dies instantly. I am getting electricity to the left side because it shocked the shaZam! out of my hand when i put it back on with the bike running.

Any suggestions?

Pull the tank off and swap coils.

I'm just going to take it into a shop and have them fix it... I've had enough and my wife is pretty pissed I've spent every night for the last week in the garage. We'll see what they say....Thanks to everyone for the help!

Whelp looks like I'm doing this myself now none of the shops around here work on anything that's older than 1996 and the one that will is booked out 2 months. FML

I'm not sure if its a coil issue, it definitely had spark going to the plug wire when I pulled it off. I'm going to do a compression check after I go buy a gauge on my way home tonight. I think the float might be stuck closed if that's possible?

Tell them it's a 2010 with the fairings removed. The motor is the same, and there are very few differences in the carbs through the years. Or don't they know how to work on a bike without plugging it into a laptop?

Back to switching the coils: switch the spark plugs as well. Adidas got a couple bad spark plugs - including new ones. If the problem stays on one side, then it's either: carbs, valves, or piston rings.

Thanks a million Rich!!!  new plugs fixed it  Thing is fast as hell now! well compared to what it was! you should of seen the nasty black smoke that poured out of the exhaust when I swapped the plugs from all the unburnt fuel.

Whelp just got back from a nice 1/2 mile trip pushing the bike the whole way after it died... just cruising around a turn in 2nd then all of the sudden just no power and bluh it dies.

Before I took it out at idle there was fluid coming out of the left exhaust pipe to head connection. It didn't smell like gas but I don't know what else it could be? it made a pretty good puddle but wasn't oily either, and when I first started it wouldn't rev again and then all of the sudden it came on and ran fine until just before it died.

Now it won't start at all, it turns over with the starter but will not fire. I pulled each plug and it sparks against the cylinder head. So it's either compression or fuel right?

Bump

Could just be condensation if you haven't ridden the bike much lately.

Are the plugs wet after trying to start the motor? And keep the battery charged up while you are trying......

[Tronspeed3]

I had the battery jumpered to my car battery and the plugs looked dry when I pulled them.

[mister]

Hat to state the obvious...

Do you have enough fuel?
Have you tried it in prime?
Is the undertank petcock set so the notch is up and down?

Michael

[Tronspeed3]

Yes there is gas in the tank and the fuel lines are full since I have clear ones on there. I rode it 100 miles round trip to work last week without issue. I parked it until yesterday when it fired right up and then died mid trip.

I've tried it on prime, res and on and it still wont even act like it wants to fire

[Big Rich]

If the plugs are dry, then it's probably your carbs. Make sure there is gas in the bowls first. Then it may be time to clean your pilot jets and enrichening circuit (choke).

[Tronspeed3]

Whelp just took the bike apart again and checked the fuel in the float bowls and there wasn't too much in there. I didnt have any clear tube handy so didn't check the hieght via the drain. I pulled the carbs off and am gonna try soaking them in pinesol and blowing out anything with the air compressor. Also ordered a rebuild kit off eBay so ill probably let them soak until that gets here. I will check the float hieght before I put the bowls back on.

[dropitlow88]

pinesol? Interesting.
