I would check/replace all o-rings and the dust cover and see how it goes.

Did it just start happening or was it like this from day go? I also get a little bit spitting out but nothing worth worrying about.....yet

Providing your temps are ok and you have a light smoke trail at full throttle then yeah try leaning it out a tad and observe the difference

THanks bro..

Anyway..if we chg the bearings from normal to ceramic type, does it shows any changes?how is performance wise?or is it just to make the bearing last longer?pls advice..plan to chg both to ceramic..
i dont see any point if u change it to ceramic bearing i downgraded my os speed from ceramic to normal bearing. and there is no difference in performance, run time and temperature how do i know this? my carburetor was set previously used on ceramic bearing, when i change to normal bearing? i didnt tweak any needle and it starts in a single kick! some might say, ceramic bearing is over rated.

Its just happen after changing front bearing..
im not sure whether all the spitting is cause from the dust cover or somewhere else..but what i can see is obviously the spitting oil is from the end of the dust cover near to LSN needle.

Neway..may i know what is the max temp for this OS TZ to stay in good condition and in top performance..normally i ran it out for 130 Celcius..is that ok?
thanks

Went back to the OS1040 pipe, engine performing well. Not as fast on the backstraight as the Red Dots and Nova's but makes up for it on the slower infield sections. Have ordered the newer OS1050 pipe, hope to get it this week.

Had increased the Nitro from 20% to 25% but at the end of the heat engine was idling very high unlike when I was using 20%. Any ideas, maybe it was too lean and got too hot?

when u didnt tune it right after changing, it is supposed to be lean and result in hotter engine when u increase nitro content.
a possibility of detonation which really occurs when changing from 16% to 25%.

when i change rubber front bearing, i notice my dust cover leaks a bit of oil at LSN, but it just give it a wet look, not spilling. according to friends, its normal if u get it too rich or if the o-rings worn off. so i lean it out a little, no leaking found.
as for engine temperature, normal run with the best power about is 115-122. i've seen people running 125-130 constant, and still the engine last 2 years.

no problem,im glad to help
there is no standard set on how often. maybe once a month if u run it every week.it all depends if u have an overheat or erratic engine behavior.
as an addition,the higher the fuel quality is,the less often u need to service it

what people normally recommend for OS TZ motors is T1050, SAGE, and HEC turbo. all are about the same price any where.
