Hello everyone. I was hoping someone could chime in and give a little advice. I have 8T 2.0 running a Bonito in it. The truggy has plenty of top end. I was hoping to get some more grunt down low. I'm running a 41021 header and 9853 pipe. The pipe has a few dents in it so that may be affecting the power. Is there a different pipe and header combo that would give me power on the bottom end of this Bonito ? Thank you

what are you running for a clutch and fuel ?

I'm running a Losi 4 shoe, 2 aluminum with gold springs and 2 composite with green springs. I run Byrons Race Gen 2 30% fuel. Thanks

is a p5xlt a good motor?

What's the difference between the keep off and the mugen bt5? What's the pros and cons for both?

Thx

Great engine. Works in buggy and truck, has good power and decent mileage. Very hard to beat if you factor cost into it.

Norwood, its fine when mine ate a plug it was within the first gallon and that was over a year ago and I ran that engine Saturday and it still runs like a top.

My piston and button still have nicks in them and it does not affect the engine.

Well a few things that I think will help in order of importance..

Drop the stock Losi clutch in favor of a M2C with hard shoes.......

Drop the 9853/41021 in favor of a 9886/41001

drop the Byrons race in favor of Werks or Bones brew fuel ( Byrons race gives up noticeable HP to these other 2, especially bottom end crispness )

Hello everyone, I have a 1/8 scale buggy running a Novarossi .21 engine. I have been out of racing for around 5 years and it has set. I have got my buggy running now and let it warm up and run a tank of fuel through it before opening it up. The temp isn't getting up to normal level, the hottest I've been able to get it is around 160 degrees, I know i need to lean it out to get it to normal level but I also have had to back off my throttle control at idle due to it idling so high at start up. I don't know if I need to take apart to work on carb or what to do to get it back to where I don't have to keep my throttle backed off so much. Any help in this would be greatly appreciated, I hope I have explained it well enough so someone can give me some guidance. Like I said, I've been out of racing for a few years and trying to get my buggy back up and running so I can complete again. Thanks.

either your idle gap is too large or your linkage is hanging the throttle open.......

how do i adjust the idle gap?

the linkage seems to working fine, I looked for hang ups but haven't noticed anything.

Do not use the radio to set your idle. That's a big no no. Idle gap is set with the idle screw. Radio should be set so the slide is all the way back against the idle screw when trigger is at neutral.

See the angled screw in this picture?

That is your idle adjustment.

Thanks for the info, when I first got it started from setting for years the idle was really high so i had to use the throttle control at the time to tune it down until I could find out exactly how I needed to adjust it. I will work on it and hopefully will get it tuned in correctly. I appreciate all the help.

i have a plus-4 and it's around 3 years old. I'm thinking of getting another nova. Not sure what i should get. I want somethign linear, easy tune, and long lasting. what's the differences between BTT, mugen BT5, Keep off, or what ever else is hot from Nova.... details please!

Does someone have a diagram showing the idle / low / high needle locations on a Novarossi offroad .21 engine. keep in mind this engine is about 8 years old but practically new due to not being run for several years. I've been looking online for diagrams and unable to find anything.

Thanks.
