Basically i need what the title says i need a .21 engine for my new losi 8ight but just as a temp till i save up enpugh for a real good 1. Ill take some w/ exhaust and everythign also.

just save upa nd buy the new motor, its much more worth it

yeah just save up for a new nice one man...(RB).....just ask ponch about used motors....haha

Is your rb's front bearing leaking?

tlkaing to me rocco??

yes

well, i think so, because whenever I run a tnak or two i look by the flywheel and theres burnt gas and stuff, that i blow off with the air compressor

Yours is the 4th one ive heard of doing it....

I have a brand new one in box sealed for sale ...If anyone is Interested PM me

Kevin, if it helps I have my case from my rb with bearings. They didn't leak if I remember correctly, it's yours if you want it.

why??? is that a problem?

i dont see why it would be a problem, seeing how its keeping that bearing lubriacated???

no thanks, matt

if oil can get out in large volumes dirt and ait can get in!

It's not supposed to leak though-the oil gets to the open (inside) side of the bearing because it doesn't have a shield.

well how should I fix the problem then rocco?

New front bearing

hmmm, well ill take the motor apart tonight and possibly tke pics, and then ill decide, how much are bearings?

front bearings can leak a little with no ill effects..... it's actually somewhat normal for a front bearing to leak a LITTLE.... if there is a significant amount of gas coming out it's not normal.

its not significant, just small, like you can only see it when you flip the car and look right at the flywheel, its not like dripping, ill try to get a pic or show you guys at the track

Yeah i agree tex... Corey Crosley,dimo, another dude from this weekend whos name escapes me and now kevin all have the same motor and all have displayed the same thing... Look at dimos buggy after a 5 min qual... Serious leak... I can only assume dimos started as a small "normal" like leak...

Kevin i think if you go on amain the bearings are under 20 bucks. I put one in befor its simple.

oh im sure its simple, just hoping puttting a new one in wont screw the motor up.....if i put a new one in, will I have to re break it in so the bearing gets broken in??

naw im pretty sure they require Zero break-in. If its just alittle burnt oil comming out dont worry, thats cool . Dimos motor coats his block and chassis ... Before it gets to that point fix it!

welli have pics ill post up tommorow, the bottom of the mill is coated with grease and a little dirt, from the 3 day weekend....so I dont think its too bad yet

u do have to break in bearings, just run a couple tanks slow without blipping the throttle hard you want everything to get seated inside the bearing

Kevin, that sounds a bit excessive. When I say a little oil should come through, I mean a little, not coated on the bottom of your motor.

well heres some pics, Im guessing it may be a bit too much??



this is after the 3 day race
