Hey Guys, maybe you can help me out on a 900RR.
i had this thing running great last summer but it has sat all winter long. Now it is doing the same thing that it was doing when I first got it. The motor spins over but it will pop thru the exhaust pipe and make a hollow sound from the pipe.
I had the carbs off today and totally cleaned everything and reinstalled. I did the exact same cleaning that worked last year.

Any ideas? I cleaned all the plugs but wonder if I just need to replace them. Also wondering wether I may have crossed a plug wire. Do you guys know which wires go to which cylinder. I thought that I did them one at time but who knows.

I have the air box off now, and when it pops, you can see a spark in the #1 carb..

Thanks in advance

 

The wires are labeled (on my 99 they are anyway)

 

carbs,carbs,carbs...
that's all I have to really say..
unless you drained them when they were clean..
that's what you nee to focus on..

I'm just about to sort my carbs on my 918 RRV!
They are coming out tomoz hopefully and taking a bath!

 

I had the same problem with mine. Changed the plugs and it was fine.

 

I cleaned all the jets and floats, new plugs and air filter!
Running much better now!
Happy days!
