Tips for starting a bike after 2 years sitting?

4 posts in this topic

I have an 02 YZ426F about a year and a half ago I started loosing the clutch in a race, so I put it away. now I've put a new clutch in about 5 months ago, after a year of sitting, I managed to start it for about 2 mins and it stalled and would not start, I am going back to get it ready this weekend and I need tips. The carb was factory rebuilt just before the clutch went. I added fuel stabilizer before it was put away.

What I'm giong to do is:

-Drain the fuel tank and add fresh fuel.

-pull clean and gap the spark plug.

-clean and oil filter.

What I need to Know is:

-Any thing else I should check?

-When should I shim the valves?

and most importantly

-I found a small amount of metal in the oil after the clutch change, I flushed 10L through till there was no more, but could those be from the clutch, or should I rip the engine apart now and rebuild it before I try to start it.?

It ran like a top in the last race untill the clutch started going, first kick, hot/cold, like a top, piston and valves only have about 10 hours of use, I need solid advice on my next action.

Thanks -Matt Moran

Pull the carb, clean out all the jets with carb spray and compressed air replace the small jets and reassemble carefully.
