anyone test this combo

hey Monty whats the f/r bearing sizes for and older p5 ? and the toro nero ? thank you !!

The X7 is a Nova.

old old pre p5x is 14x25.4x6mm anything p5x or newer is 14x25.8x6mm , toro nero is 14.5x26x6x6.3mm , i would recommend sticking with the stock novarossi bearings especially with the toro nero size as i havent found a bearing that i am happy with in that size .


as for the front bearings in all nova off road i would recommend part #17011 7x19x6x6.3mm


hope this helps


doogie?

jp-4 works fairly well with nova engines actually

um runtime difference , hmmmmm well the nova plugs will yield better runtimes when properly shimmed and tuned , you can lean on the nova plugs a little more and they will hold up better but are a little more difficult to get the tune spot on .


c5tgc and c6tgc are the two nova plugs i would keep in my box


nova = longer lasting but a little more difficult for the average joe to tune but will yield more power and better runtimes if tuned properly
odonnell = shorter life but easier to tune

he must have gotten my bench break in

That was my engine Monty.

It had a few more than 6 tanks through it. The bench break-in is great ... you know the critical part is spot on, save money on fuel (to pay for part of the service) and, the big one for me, the time you save.

Y Thank you sir !
Yes it's Doogie Whatssssssss up !

Get a hold of me if you need anything Doogie

Hi guys..I really need help..
I have just run in my plus4 and was using it for the race last weekend. Im using the Dynamite 053 pipe and 30% Mecca fuel. Here's the problem.
After the straight stretch which is about 40mtrs, as i brake and negotiate the hairpin, the engine will flameout. It will only not flameout if i were blipping the throttle. Whats wrong with the needle settings?. Im using the odonell 097t plug.

I doubt the HSN is too lean as the engine is not bogging. Im using the 7mm carb restrictor. If my LSN is rich, will it cause the problem?Maybe its a bit rich as when the engine is fully warm up...It takes about 8-10secs before the crankcase is fully load up with fuel.

The HSN is only about 1/8 turn in from default. The LSN is about half turn in from default. I knw that its all in the needles but I really need some help here.
Theres no problem with the car as it was running fine with my old RBC6 the week before.Thanks..

Check the idle, it might be too low.

The idle could be one thing as mentioned in the previous post but something else to keep in mind is the needle positioning. A very common mistake is people will run the hsn too rich and to compensate, they lean the lsn to clean up the bottom end but as the engine builds heat, the engine naturally leans itself out and if you are running too lean on the lsn, the engine builds even more heat in the infield and cools down in the straight away but over time, the cooling effect will not be effective and the engine will tend to flame out when the slide closes as the heat buildup in the carb from the lean condition evaporates some of the fuel entering the case and the hotter the engine and carb gets, the more fuel and the quicker it evaporates until there isn't enough getting to the chamber to sustain continuous operation.

If the engine is doing it right out of the gate, try raising the idle a little and/or going to a hotter plug but if it runs good initially and it is somehting that happens several minutes into a race, retune the engine so the lsn and hsn receive proper fuel delivery at all times.

The engine will start to flameout about 5mins into the race. But the question is it didnt happen during the 7mins heats. After 3 flameouts consecutively at the same place, I gave up...
My HSN is almost at its default setting and my LSN is about 1/2 turn in from default.
The engine is not overheating as it can be restarted with ease after it flames out..

I would slap a new 97t in ur engine just for shits and giggles...
What happens is when the engine fires up it idles a bit high and it takes a good while for the engine to get really warmed up. About 5-8 minutes during the main....Then the idle drops and the engine seems to mellow out just a bit...

this is why you need to thorougly tune ur engine during practice....and remember mains are usually later in the evening and the humidity comes in and causes the engine to be a bit richer than it was....

Before every main fire it up and let it warm up and lean the bottom end about an hour, and raise the idle just a bit too, this will compensatefor the drop in idle during the main....

There is nothing wrong with ur engine.....Most likely.

Put the top end flush, and lean the bottom about 1-2 hours, just remember the bottom end is a sensitive adjustment and a little goes a long way, then after it idles great after 5-10 minutes on the track readjust th top end just to make sure it ha plenty of speed....

I hope this helps.....
