i guess the older generation of novarossi engine are more reliable right?

not necessarily , but i do favor the 14mmx25.4mm over 25.8 or 14.5x26mm bearings just maintenance , no big deal to me , i love to work on nitro engines

i see. guess bigger bearing doesnt mean good too.
so you bought yourself those bearing tools to install the bearings/?
do u use ceramic bearing too?

houston

iTrader: (96)

ceramic bearings increase engine performance dramatically
i use heatgun to change bearings

rossii

i see. do u happen to try those ceramic bearings before?
oh, heat gun will do for bearing changing? how bout taking the bearing off the crankcase?

houston

iTrader: (96)

i have changed hundreds of bearings this way (literally)
i use the tko ceramic bearings for 14x25.4mm size and 7x19x6 for the front bearing well performing engine bearings

oh tat is good. tat is the easier way to change bearings.

how does the exhaust restrictor that comes with engine effect its performance and fuel consumption? does it have a dramatic effect?

The reducer should increase bottom end torque.

thanks for the quick reply


so i would i be right in saying fuel consumpion would be improved on a shorter track because less throttle would be required?

Sorry Chaps old thread i know,

just got hold of a 08 model and im starting run in

but i have a question

does it matter what way the button goes into the crankcase as it has little dimples on it at each end ive not seen this before so assumed they are there for a reason

any one clear this up for me i understand im probably being a numpty

The 4-dimples are usually the 'exhaust' side.

Megacrash

Hi thanks i think i understand what you mean,

ive attached an image with black circles of what i mean do i have them the right way around then

Not 100% sure, but from what I have found and seen taking them apart, the 4 dimples goes on the exhaust port side with the single dimple at the carb side. I don't remember if my 367 head button had that many dimples.

Also, you need to shave the case to clear that driveshaft in the MP9 and tighten the screw to the radiobox lid

Megacrash

Ah cheers Buddy ill do that now before i forget with the dimples

and as for the other bits ill do them to i bought the car used but never used so i may strip it down and re do it

Cheers for the tip though
