Hey Dino, how about that. a turbo onepiece head, with maybe six ports instead of three. I know you think the 3 port is enough but your competetion are all releasing multiport .28's

A .28TH (turbo head) I can see it now.

STS keeps changing what comes with the motors. first ones came with all three shims for a total of 6mm then they changed to just the sliver 3mm now they put .4mm worth of shims in . I think they readded the shim to make breakin easier on you and the pullstart.

thanks.

ok I started it the breakin process and so far so good except that i burned 3 spur gears, the cb is melting the spur gear teeth, why is my cb getting so hot?
other wise i let it run for about 2 mins and temps are around 210+/- idles good, stays running for the whole time.

Are the clutch shoes rubbing at idle?
Are the bearings in the bell o.k.?
Is the bell improperly shimmed? Too tight?

I have never heard of this before, there is no way the motor can be doing it.something has to be rubbing on the cb to get it hot. wether its shoes or bearings , something right there is causing it

When you have the engine started make sure its not trying to drive at idle (wheels should not spin when you pick the r/c up) If they do you have clutch problems.

i adjusted the idle and the wheels were not turning and the truck was not pushing or trying to go, plus right now is so rich that even if i give it gas with the control it won't move. the last spur (3rd one) last it longer than the first 2. like i said i ordered all new clutch and cb, bearings etc. oh and 5 more spur gears just in case.

very very very strange. I really hope its just a bad bearing but to melt your spur is so wierd. I would like to see a vid of it running and melting the spur.
if its not a bearing I am stumped

Thumbs up NEW sts .28 here

I got my new sts.28 in today and installed it on my Savage. I had to modify a few things, but I have it working now. I put after run oil in before ever pulling crank rope, this really helped.The compression is unreal on this motor. Then I ran 6, two minute cycles with the engine. After this point I started driveing the truck around a little giving it 1/4 to 1/2 throttle. I find the motor to be reved a little high at idle. I am certain that this is due to how rich I am running the motor. Tomorrow I will lean down 1/16 turns at a time to get the idle right. I cant wait to see this bad boy RIP!! The motor sounds awesome.. I like the look to, It is really going to look good passing those T-Maxxes I am sure that it will make some of the fellas around kinda pissed. Oh well they should have purchased a sts...
Thanks for all of the help on here. I will keep you guys updated on the progress of the truck.
