I have recently bought a 2001 yz 125 and its a bit rattly, i stripped the head down, had a look at the piston and rin which all looks ok, whilst striped i cheaked the con rod for play and it was ok, i put a new ring in it as it was stripped and put back together, its still the same and sounds like its got piston slap or something. Anyone have any advise on what it could be?? small end bearing?

my bike keeps on not having a spark and i have to puch wires wiggle wires. does anybody know the prob

Just wanting to know how to wire one light to my ttr125le. I need to know what wire to splice and where it is on the bike.

I bopught a POWER COMANDER USB by DYNAJET for my 700R ive got it all tuned in for the woods and track but when i go to the dunes it really leans out, i have a laptop so i can mess with all the fuel curves when im there ,but if somone new were to get a map i could download or give me some ideas that would be great.

My 700R RAPTOR is running to lean at the dunes ive got the DYNAJET power commander usb so i can hook it up at the dunes to my laptop and ajust it but would be easyer if somone already had a map i could down load or tell me how to adjust the all the fuel curves.

where can i find a vin number on my dirt bike. i have a 1987 yz80

ok, first off thanks to all those who helped me with finding the problem with my carb on my 2001 yamaha ttr125l, i can gladly say that it is up and running now and i went for a easy ride on it this morning.

i need to tune the carb though, it wants to start with a half or more open throttle and as long as i keep the throttle open it runs, if i let the throttle go back to "idle " position it will bog down and die, there are a few jets and things to adjust i just dont know which ones to adjust? the throttle screw set is as tight as it can go, which should mean it idle high, but doesnt? i am new to dirt bike carbs. so any help to tune this thing so it can idle with out me on the throttle.
