At a loss????

[D Slicker]

Ok, Three weeks ago I was working on by BR’s with Alex and was landing pretty hard a times. Towards the end of the day my ski developed a stumble when I would go from just of idle to full throttle then would run like a raped ape. It I went from anything over quarter throttle to full it was fine. So I figured it was the carb’s. I took them apart and made sure the low speed circuit was clear put it back together and it was worse. I am at a loss as to what it could be. I have put the stock coil back in and checked my flywheel. I am checking the water box tomorrow and weather permitting will ride. Paul has given me some direction and I have checked those. Does anyone have any ideas? Here are my mods.

Milled Head for 93 octane
Stock Carbs re-jetted
Factory Wet Pipe
MSD Coil
Advance kit
RAD Flywheel

I am pulling that out today to see. Anyone else????

did you check to make sure the cog looking thing on the end of the butterfly shaft isn't slipping on one of the carbs. Mine was doing this but only after i was ridding for a while for some reason and i was chasing my tail most the summer trying to find the issue.

That was one of the first things I checked. Its was good.

Damn I'm still worthless then :banghead:

Needle and seat is in good condition? Just asking, could dripple through and that really messes up low speed jetting.

 

[D Slicker]

Yep, carbs are only 2 seasons old.

Maybe you wore out the power bands?

I could have, or maybee the bearings in my wetpipe went. :biggrin:

If I dont figure it out soon I may have to ride my X-2 at the rager.

Ok so I pulled the waterbox out and It seams fine no rattles or noises. I put the stock coil back in and went for a ride(its cold) and still doing the same thing. WTF

 

[sjetrider]

sounds like a chipped read to m bro, i had same problem a few mos ago.remove F/A's and start it and see if any smoke comes out a carb (even a little smoke.

 

[D Slicker]

I checked the reeds when I pulled the carbs off and they were fine.

 

[Powder]

voltage regulator maybe? I have one you can try.

 

[D Slicker]

maybee, I can check that at the garage where i keep my ski's.

So I went to corsons today after going through the carbs one more time. Pu the ski in and it ran the same. Put it back on the trailer and rode the X-2 for the day. After I rode I came back and started the SX-R & X-2 to clear them out and my SX-R started to run away so I killed the fuel. When I got home I noticed there was oil comming from the rear seal. I seam to think that may be causeing my problem. What do you guys think.

 

[ANT]

spray some carb cleaner at the seal while the ski is running and see if it revs up some if it does then the seal is really bad.

I was going to presure test it tommorow.

I was going to presure test it tommorow.

That sounds like a much better plan:biggthumpup:

Sucks because the rager is in 5 days and I realy want to ride standup and not my under powered X-2
