I recently switched from the RC8.2 standard clutch to a Werks (Heavy) clutch system. Would this affect my tune much? The car ran fine but seemed to idle a bit irregular (faster). Almost sounded a bit lean. This is on a Plus 21-4.

i dont know anyone who uses the heavy flywheel from werks or any other manufacturer for that matter

i would recommend getting at the heaviest the medium weight flywheel

the heavy flywheel will make your engine feel as if it is doing some weird sheeit

Thanks, like I said the car ran fine just idled a bit weird.

the weight of the flywheel is probably keeping the engine rotating even after it wants to come down to idle after the fuel has been spent out of the crankcase

Makes sense. I figured it was something like that so i didn't want to start twisting needles for nothing. I need to geet my hands on a medium flywheel as I like the feel but the idle is bothering me.

I spoke to the people at Werks and have been told that the Heavy clutch should actually cause the engine too idle better. So now I'm a bit confused. One person saying it's no good and the other saying it should be better.

i think you are misunderstanding what i am sayin , the heavy flywheel will keep the engine idling through rotation of mass and in turn will allow you to lower the idling of the engine . i was trying to tell you that the heavy weight of the flywheel will keep momentum for a longer duration and force the engine to rotate after the fuel in the crankcase is spent , hope that is clear , sorry for any confusion

What you told me was what I was thinking but the Werks tech said it should idle better that's what's confusing.

I can tell you who is excited about the Roma .25 truggy engine!!!

This guy!!!

Soon so i am told

Already pre-ordered mine from Monty.

Hey guys, I need some input.....I am having a bit of problems with the idle on a 21-4BTT. It only has a gallon, maybe a bit less on it. The idle is rich and when I lean it out, it goes from rich to pinging. I can't get it just right. I have a 21-4C Team, and I can get it perfect.

I have replaced the glow plug and went that route....I don't think that is the issue.

Any ideas? Do i just need to run it rich and let it break in more maybe?

Are you dropping the idle gap when you lean it out? Sounds to me like its too big

hey guys i dont have a issue but a questern i have two btta motors one i brought a few months ago and one i broughts this week for a big race they are both identical part numbers but the older one has a nova branded bearing and the other has some random bearing the one that can be view from out side the engine

is this normal alos could this be a fix for the dodgy nova bearing issue ?
