im going to buy a new pipe in the rebuild. what pipe gives the best high end? im using a FMF power core 2
also i drained the oil from the engine today and it was GREY. some how i doubt they sell grey gear oil. so my guess is water is entering the engine. can it only enter threw the water pump area? or is there other areas? i want to run the bottom end this year and then send it out for a rebuild next winter.
thanks

 

For a high-end pipe check out the LRD adjustable or the FTZ. Both make excellent high-end pipes.
Do you know for sure that water is leaking into the tranny or was your ride submerged? Try putting in fresh oil and ride it and see if you continue to have the problem, then go from there.

 

i bought it rode it down the road once and tore her down for the rebuild.
when i drained the oil i seen the grey oil. i figured while the motor is out and i am replacing the clutch i might change what seals i can get to.

 

Some of the bearings/seals on the water pump require special tools. If you need to replace anything other than the gasket, you may want to just have your local Honda dealer do it.
But, like I said, you just changed the oil and really don't know how the quad was treated before you got it. If you put fresh oil in it and ride it awhile you can see if you're getting water in the oil, but then it would be getting hot also.
Are you just wanting to "rebuild" the motor?

 

i was hoping to rebuild the lower end next winter. i was going to do a compression check on the top end when the bike gets back together. but from taking it down the road it still seems to have good power.
im replacing all bushings and bearings ETC on the rolling chassis and its adding up fast so i was hoping to wait on the lower end. still havnt got my frame back from the blasters yet. so progress is slowing down.

 

the grey oil is from the clutch plates. It is normal. If you want a top end pipe, I'd check out the Eddie Sanders Racing pipe, its a very nice pipe.

 

Dill is right, gear oil changes to grey when you use aluminum clutch plates. If it really bothers you change the plates to steel and your oil should not change to grey.

 

for some reason i just thought that grey oil meant water in it
it dosnt bother me if its not hurting anything. i bought a dirt digger clutch kit for it. will put it in after the chassis is on 4 wheels again.
thanks for the help.
