If you don't feel comfortable opening a motor don't have someone show you. You can bust the piston skirt off see it many many times. If you can't find help you can send you mill into a number of guys here. That way they can inspect. Pending were your located there's renew, monty, CRE, RW mods etc

I recently rebuilt a Bonito and it isn't the easiest engine to tune, but the first thing i thought of was the condition of the internals after sitting for a while.
I would recommend taking the entire engine apart and cleaning it and buffing the crankshaft. sometimes the bearings and crank get rusty while sitting without lots of oil. I think if it is done right the engine will run much better without much replaced. worst case the rear bearing may need to be replaced and possibly the front, but I'm just guessing. the orings usually last a long time in my experience. if i remember right the low speed needle likes to be just out from flush and the high speed can start flush to get you running. also make sure the idle setting is readjusted. that one is critical on that engine.

Hi All,
I have a +4 that previously had a 9901 pipe (with the header from a Losi RE10, which looks similar to a 41020).
As part of my learning experience I thought I'd try some new pipes this year, so got a 9853 and 41001 headerb(looking for a bit more in the very short run up to a tripple we have).
I'm no tuning expert, but I found I had to lean out the low speed a lot (~8 hours or more) when I put the 9853 and 41001 on. Now a good bit in from flush (was pretty much flush previously).
The thing is still sounding 'fluffy' down low and in to mid range. Performance seems ok, but not great, it feels as though it's still too rich...
Is this expected? Is there something I may have done wrong and should be checking? I was expecting a little tune variation between pipes/headers, but this is way outside what I was expecting.
Cheers,
Michael

Hey guys!
Got myself a new package car and engine, I got the novarossi plus 4C 2010 team engine for my buggy.
I heated the engine up to 100 degrees before starting which gives less stress on the engine.
Had problems starting it up so i thought the plug was shot. Took the plug out for the first time and it some shavings around the thread of the glow plug, Does novarossi have a problem everynow and then with a engine or 2??
This was purchased brand new in the sealed box.
Heating the engine to 100 degrees is 2 hot??? carb hot which the fuel is evaporating and not getting into the engine which i couldnt get it to idle on the factory settings i havent changed anything on the engine?
Any ideas???
Cheers,
Troy

Where about in oz are you.
I'm about to buy the same set up. I'm in Brisbane. Will let you know how it goes but have you checked your clutch lately.

of course they wont idle at factory settings, that is far too rich....you need to lean the needles a fair ways from there they come in order to get the engine running nice

Hi Shimano.
I'm in Canberra.
I'm running a Buku, which so far has been flawless. Didn't seem to be slipping or performing poorly from a clutch perspective. Just a 'fluffy' engine sound in the low and mid range, even after leaning the LSN about 8 hours or more. As stated in my origninal post, I was expecting to retune after changing pipes - just not by that much...
