Losi 8ight building and setup

Thanks.

Hey guys I am looking for a new motor for my 8ight and my limit is $200.00 dollars and I was wondering if this is a good motor and if anybody can tell me if it is worth buying. Now I know it is a Italian made motor so I know it will be good.

And instead of grabbing the caps with a pair of pliers, just run a small screwdriver or allen driver through the shock mount eyelet on the top of the cap to turn it. Losi put a hex shape at the bottom of the shock body, so you can grab there with a wrench while doing this.

i ran that engine last summer, i loved it. lots of torque. i ran an 053 on it and o99 plugs. if you are running on a big track it will run out of leg on the straight a little but as long as its not a 170' straight you will be fine. i am going to order another one for this summer.
1 thing thats i was told by jim hott. from fusion, take the "brass boost port plug" out of the block and jb weld it in so that you dont have it come out on you. thats how i lost my bf, lost the brass plug and sucked in dirt.

How tight should the piston be against the inner shock body wall?
My pistons seem to be very tight against the inside wall of the shock body. Is this normal? Should I sand them some? I suppose it will be smoother over time.

The .21 BF is a great motor and mine really woke up when I changed from a dynamite to JP-2 pipe.

Also, make sure you stick to one brand of diff oil, so the comparitve viscocity is linear...translation, 1000 wt oil may be different from brand to brand(or so I'm told). Just get 5K for the front, 7k for the middle, and 2k for the rear. That'll be a good starting point.

Well the cars been out since Oct and still no diff fluids. I'll believe it when I see it.
Let's get it right.. Release the car AND it's supporting products OR at least tell us which other manufactures oils are the closest match. It's really a shot in the dark on which oils to use to get out of the box matching performance which we tuned the setups around in the first place.

Droop
J. Wright: Post # 1963 and #1965 (nice picture) on how to measure Droop. You will need a digital caliper to measure it. You are correct. 95mm in the front 106mm in the rear. Hope this helps.

Mugen, Kyosho and GS are all exact C.P.S. differential and shock oil. I would reccomend running one of these so you know your oils are exact.
I ran 5-6-2 this weekend and it felt great! The car was very positive and pulled of corners very well. I'm going to try 5-5-2 this weekend.
