421venom

Ok i will get that checked out thankx alot guys

But if that o ring is bad can antifreeze get to the oil? I thought they were separate cuz its transmission oil

is the o ring inside? where the water pump is?

Hey guys i need help...my shee was recently rebuilt and when i put the engine the bike ran great and i noticed a clicking sound coming from the crank case and today i did a oil change and antifreeze came out along with oil...what could cause this??? And can that do anithing with the clicking noise?? Any help is verry appreciated

thanxx alot for the help guys ill call those guys from millenium see whats up

yes thats what ima do,do you have any idea what they charge to do the plating?

yeah

those are the only sctratches, shown on the pictures

what happens if i put new pistons with the cubs like that? one cylinder has small scratches inside the cylinder from where the piston broke, will that affect the compression??

421 cool heads, whats the difference??

what do you mean??

i just found out its a 68mm piston, whats a one bigger size??

hey guys i need to bore out the cylinders on my banshee and i went to a machine shop but they said i need the pistons first but my question is how do i know what piston size i need and how do i measure them? this is the piston i have now..

the jug just one side and will any piston fit if i bore it a next size?

how can i fix it?

hey guys so i took apart the head and found out one piston is broken and combustion chamber is scratched up, there are little grooves on the head,do i have to replace the head??? or can i just replace the piston and piston ring??

exhaust ring,i just noticed the exhaust is loose from the head

hey man i just checked on that ring and it wasnt placed where it should be it was hanging on the outside of the pipe,could that cause that problem??

reeds are good

thanx i will try it, if i put my thumb should i feel something?

how do you check the compression?

as heat they feel the same,as preassure nope, the side thats backfireing is lower on compression

nope

hey guys i need help with my banshee its a 421, it was running awesome and at one race it suddenly stopped,now it has a hard time turning on n when it turns on it dies if i let go off the throttle but the main problem is that it wont run the way it should,,it makes a LOUD back fire from one side it feels very week, i changed the spark plugs and cleaned the carbs but still doing the same thing,any help is appreciated
