hey guys it says OS TR(p)T specs as follows
4000- 38000
1.3 HP @ 30,000 RPM
does that mean the motor actually has more MAX HP considering it has 8,000 more revs to go if you know what i mean? :P im getting either a OS tr(p) T or OS TR R-spec which ever i can get my supplier to order! as he never ordered from tower.

You should get the R-spec since I believe it's the only one that has a machined piston.

I am getting my TR R-Spec modified as I speak. I have found that the motor does not like to run under 230. It seems really rich if it is not running above 230.

Default Engine stalling

G'day All,

I've has my OS-TR for about a year. I have been very happy with it. However I haven't been able to finish a race for the last three meetings. Any sort of bump and the engine just stalls. I have replaced plugs but still the same problem.

The compression is pretty poor now and I'm wondering if that is the problem. If so what tools do I need for a rebuild or is it cheaper just to buy a new engine? My feul consumption is through the roof too. I would appreciate any advice.

Ya i wanna get the R spec as well for the bigger head and that its 3 port turbo (better fuel consumption than the 5 port turbo) but there arent any available on hong kong sites only place online i've seen them on is towers and my supplier doesnt order from towers!

Browny, try re sizing the p/s.....pinching. Check out this site. I think that they are cheaper than new p/s.

Brain Teased, why do you go through a supplier when you could get online and purchase the engine from tower yourself. Cut your middle man.

Nah cause i dont trust using my credit card online dont care how safe it is now just dont trust it! i read a few posts back that the R spec had trouble with the turbo head button? also cant seem to find the R spec engine on hong kong sites?! or any of those aftermarket heads for the OS TR's :P as when my supplier gives me the bad news that i cant get a OS TR R spec ill just get the 5 port turbo model and try and find a bigger head for it i saw them on rc-mushrooms.com like 2 months ago! but all their stock for OS parts are gone! only thing left is 5 port piston and sleeve set.

#8 works ok on almost all os engines. in my expereince, A3 gets the engine in the right temperature faster compared to the a5 and #8 plug. hope this helps...

Dokidoki There is alot of difference between the two. The stock is well...stock. The zac modified engines are modified to various degrees. you can get everything from only sleeve porting work all the way up to crank balanced and fully polished zacs. Also a big difference in price to the stock engine.
