[QUOTE="gb250, post: 1250745, member: 82405"] I recently took on an '85 YZ250 to breathe some life back into. After stripping the bike to the frame, powder coating and re-assembling with care I have got the bike running and functioning well. Except the bike is exhibiting signs of reed valve problems. Excessive kicking to start, excessive fuel seepage from around the exhaust pipe-head connection (there is a decent gasket in there and it fits pretty snug with all 3 springs intact) and the spark plug is soaked when I pull it out after running the bike for a few minutes. It rides ok, but is a bit boggy when you crack the throttle. Not crisp and sharp. I am not sure of the jetting and needle setting, as well as I am not sure the stock settings and jet sizes. Its a Mikuni carb, didn't take down the model but I can if anyone can use it for reference. The air filter is clean and oiled. I will be emptying the tank and using a new pre mix, there was a little old gas in there which I added to for testing, also will pick up a new plug. I pulled the reed block and have found what looks to be some kind of backyard mod that someone has done. There is no stock reed stops which I believe should be there if stock parts are intact, and there is a set of 4 opening reeds present. A plate with 4 holes, with a plate with 4 fingers cover each, on each top and bottom of the reed block. It appears as though someone hack-sawwed off the reed stops as well. Will this cause the excessive fuel and trouble starting I am experiencing? I have some new Boyesen reeds on order and will be putting those in this weekend. Attached are front. Please help! [/QUOTE]
