good usable power throughout the power band.. track dependent for mileage but 9-11 mins consistently.. 2135 pipe. 41021 header.

anyone got a recommended link to what they feel is a good breakdown of going through your engine and prepping it for winter storage?

what if the pistons material is created to expand at operating temperature in a calculated ratio more such than the brass/chrome the liner is formed from?

Yep, and those engines I have seen like the Kyosho RTR stuff. Almost no compression when cold but they do start and run well.

When heating the engine to start it for the first time, don't just place the heat gun at the top of the engine, you need to move it around the sides and even the bottom of the chases where the crank case and bearings are. You need to get a good amount of heat in the engine before trying to prime the engine with fuel this will make it start a lot easier. Make sure your glow ignitor is charged fully, most of the Nova plugs come with a little oil in them, I always take them out first and test them to get that bright glow before trying to start the engine. Replace glow plug, heat all around the engine, top, bottom and sides.....prime the engine, then it will start right up. If it does not fire off and stay running lean the idle screw a hair just enough that it fires and stay running. From there follow who ever you follow for break in. My method I have been running these engines for 20 plus years never has failed me and they last, but we all have our own way. Getting it started for the first time is pretty standard. CHARGE YOUR BATTERIES IN THE GLOW IGNITOR AND BOX FIRST!, HEAT ALL OF THE ENGINE, PRIME IT, THEN IT WILL START,

Mephesto is a very good engine, very easy to drive and gets decent mileage, don't be afraid to run it with a 7.5mm venture to get the power out of the engine. You will still get good mileage with this setting.

YES..... add the water into the pipe and use the black caps that come with the engines to cap off the ends.....cant believe someone asked that...smh. Leave pipe in freeze over night at the most and it will push some bad dents out of the pipe. Do not leave the pipe in the freezer to long as it will hurt the inside of the pipe baffles.

To clean the pipe, soak in concentrated anti freeze in old crock pot on low for about 5-6 hours. Take out and polish with clean towels and chrome polish. A Dremel and polish tips work good or a big table buffer works even better.

2135 is an EFRA registration number and with that registration all dimensions are noted and may not be changed. What may be different is the header connection, thickness and coating.

I'm sure this has been asked before, but new to Novarossi. Have a Bonito in a truggy (NT48.3), and was wondering what is a good pipe/header combo. Medium size track, with one straight and fairly tight infield.

I'm currently running the 41031 conical header with the 9901 pipe on 7 port Rolling
haven't got it fine tuned yet after changing front bearing still pretty rich and was pitting at like 7mins on truggy

i would personally recommend 9853/41032 or 41033 header

most bottom setup ..

I have a copy of that manual. Feel free to PM me if you are still looking.

Anybody know where to get HIPEX pipes stateside?
