The clutch is weak when trying to go slow, rock crawl start on steep hills etc with stock gearing. I have had the stock clutch with the following: 1.heavy flywheel on stock tires 2. heavy flywheel w/ GYTR gear reduction and stock tires 3. heavy flywheel w/ GYTR gear reduction, 32in tires 4. stock flywheel w/ gear reduction, 32in tires. I don't have plans to upgrade the clutch. In my experience, with the way I drive it is sufficient for me. I've tried to setup my ride on a budget. For example i skipped the 15% 5th that was 500.00 extra at the time and used the money for the tires. If i felt worried about the clutch I would find a way to "budget" the upgrade but I don't feel it is necessary. Of course I could burn it up tomorrow but I haven't had any close calls yet. For the money it seems that gear reduction would be the next best mod to do. I have no experience with the rekluse.
