if your using all of TS' parts, case, cylinder ect.. its as simple as assembly using proper gaskets ect..

but if your talking about doing the port work needed to get the most from one of his Reed Cases, there is alot of stuff you ll need to know.

I'm building a TS reed motor with the new TS head kit (once it's out in a few weeks)

I was wondering if I should use the dd263 - HRS Zero Drag Crankshaft Seal Inserts
from DDM or these dd268 - Allanach Teflon Zero Drag Seals

Any of you engine builders use these?

Also if I should go with a lightened flywheel for the 30.5 cc engine ??

And I was gonna use the craftworks spark plug wire.

The TS headkits come with detailed instructions. Definetly use a torque wrench when putting it together tho, It would be easy to over toque the 6 cooling head bolts without one.

Gonna try and use all TS stuff for now. Looks like Oneil brothers makes a good top end for the reed motor. Don't think I would ever try my own port work. That's why we pay the big bucks to the pro's..

Will his new head kit tell you whats the proper tourque?? Where can I get the tourque wrench?

Sears, Snap On, ETC

The kit will have torque specs with it.
Any good tool shop will have a torque wrench, you will need a small one that reads in inch/lbs 1/4 inch drive.
I dont bother with zero drag seals, I dont see the point in using them in a offroad car.
I do use a lightened flywheel, had no heat probs with them.
I always use a drop of 2t oil on the bearings during assembly and lube the cyl well before installing the piston.
If you use the TS fan cover you can fit and gap the coil before the cyl goes on. It would be hard to do it with the cylinder on. You also need to machine the coil mounts off the cyl if you use the TS fan cover.

You will also need 4 x m5x20 cap head bolts for the cylinder as the Zen headkit doesn't come with them.

Hey Kel... do you have a copy of the instructions you could email me? My kit didn't come with any instructions. I have to order the wrist pin washers and now I have to get the head cap bolts too I guess.

I don't have a TS engine but I've heard that the zero drag seals are not as efficient at keeping out dirt and sand.

i have a stuffed 2mm stroker in my setup, my next BIG motor build will bea full TS 4bolt 30.5 i think.
i would forgo the zero drag seals and go with a ceramic crank bearings.

+ 1. use good crank bearings and stay away from the 0 drag Teflon seals. I tried them once and they are not so good and cause more problems then they are worth. IMO Great thread

Did you get your kit from DDM? Did you get a copper head gasket with it? And are you running a stroker crank with your setuo? Sorry for all the questions, I just didn't get any of this with my kit... without tat paper, I may have f'd up my motor. Luckily I have been draggin ass on assembling it.

The kit comes with a paper gasket but I used a copper one.
Yes I got mine thru DDM.
I am using a stock Zen crank not stuffed. I got over 23500 rpm out of it the other day. That was under load to.
