DOES ANYONE KNOW WHERE I CAN GET A CRANK FOR MY EVO 3 BUT ITS NOT THE STI KYOSHO AMERICA SAID TRY BACK IN A MONTH

I finished breaking in my STI last night. What a wicked powerhouse. I can't wait to let it rip at the GLC.

Dave

Sweet....ill be there also running STI See ya there dave

got my sti home and my god what a pritty thing this is.vary nice inside very nice

i just bought a sti. i was still breaking it in on the track and it was my ninth tank and all of a sudden it shut off. i took a look and the crank broke right at the collet. brand new motor snd thought it was supposed to be improved. what would of caused this

idono send it back and get a new one. iv never hear of this happening to ne1.

How many turns out on the HSN would have it ready for racing, safely?? After break in of course..

Hey Austin.....Sorry to hear that happening to you man...I havent heard of that yet....I would contact Kyosho America and see what they tell you....I would put motor back as is....they will probrably have you send it back...also the part your talking about is the very end of the crank were the collet sits on right....

well this will all depends on weather, type of fuel, what you have head shimmed at....I could not give you an exact or accurate answer without being at hand for the tuning....I would start at the factiory setting closing or opening depending on how the motor responds if its fourstroking lean it a little vice versa....hope this helps

What does the STI come shimmed for from the factory? I see two shims here. I imagine the copper one allows you to run 30%. Am I correct?

Dave

Nope.. if you run it at 30% with the actual shimming, you'll grenade it.. you need to add another 0.10 shim or depending the weather conditions an additional 0.10mm shim (0.20 total). Measure it with the solder wire how much clearance is and tell us with more security.

It's the stock shimming that came with the motor. I didn't add/remove anything. I imagine removing the copper shim and running 20% would be a bad idea as well?

Dave

yes it would be a very bad idea......if your running 30 percent you should be using between .40 and .50 total head shims......

im gona run 16% with stock shiming

Hey, i am looking for a new engine and was wondering if the Sirior EVO III is a good choice. I have a STS RS12(few years old) handmodded engine. Will i notice a performance gain over this if i buy the SIrio EVO III?
