Rieju MR 300 Racing | Episode 3 S3 Extreme Cylinder Head & Flywheel Weight | Hard Enduro Bike Build 

Thanks mate, I run a smartcarb. So no jetting basically

Thanks Chris, I can't say for sure but I don't imagine it would have too much effect on the longevity of the engine. However I have read that low comp heads are claimed to make the bike run cooler, would could possibly have a positive effect on engine lifespan

Thanks man, good question - that is a 400g weight we installed in this bike

@@highcountryhardenduro awesome, interested in one for the gas gas. So looking around 🤙🏼

@Relentless_Hard_Enduro I think it would be a great addition for the gasser 👌

Nice review, and you confirm the extrême S3 head is a good choucroute! Do you know there is other manufacture for the flywheel weight ?
