another question the bike I bought has no plate under the chain on the rear axel should there be one there and if so where can i get one

 

They don't come with a swing arm guard. You can buy them, might want to see what they have on ebay. You will lose and inch or two in ground clearance.

 

you won't loose to much clearance were the sporket is it is preety close there but it is a great thing to have i don't reamember hitting my swingarm much but i already bent my scid plate a lil were the chain is it isn't touching but if the skid plate wasn't there i would have hit the chain. i found out recently that these machines have no clearance stock. what a difference the 2 inches make in bigger tires than teh stock ones. i love my 24 inch dirt devils great for teh scrambler great traction and yet i can still go on teh road without any vibrations or load noises.
