I was worried about this as well after reading about it on the BuggyPartsNW website. However, the truth is, the 17g sliders and red spring work very well together.

In any case, if you are mainly going to do hilly, trail riding in the Pac NW like me, the red spring is the only way to go. As for the sliders, as I said 17 gram seems to work well. One other combo I might try is real light and heavy sliders together. Say like 3, 15 gram sliders and then 3, 21 gram sliders.

However, this seems like the kind of idea that sounds real good, but in reality, (do to the laws of physics) doesn’t really work like your brain thinks it should work. Meaning the variator works by centrifugal force, so the heavy sliders probably override the light sliders entirely, and behaves the same as if all the sliders were all heavy.

yep, the red spring and the white are stiffer, there job is to keep it in low gear longer and to down shift quicker. they work well with 11 gram rollers to, but top speed will be reduced due to the lighter rollers. I had a white main spring and 11 gram rollers in my old 250

Mixing weights, you will have uneven forces in your variator resulting in either premature wear of the heavier sliders or fatigue of the variator assembly.

Why not use the average 18?

I just ordered a

Malossi clutch
Red Malossi main spring
Clutch arm springs
17g sliders
New bell

Hopefully I’ll have some good news to report late next week.

Thanks you all for the advice, and thank you BIGE for the parts.

when you get them if you have any questions let me know

This is the set up we ran at the bash in the hh250. The wife never had a problem. I'm now going from the 17g to 11 for more torque

What type of "impact" are we talking about with respect to the top end? How much of a reduction in mph are we talkin? I have a stock CN250, in a gk-13, so when I upgrade (including the CDI), I may not tell a big difference if I use, say a red main spring, red clutch arm springs, and 15g rollers (or sliders) from the stock top speed (which is pitifully slow to begin with). What type of mph's are you all finding when you modify the cn250 (or similar)? I just want to be re-assured that I'm not going to dump some cash on the tranny, carb, elec., etc... just to gain 5 or 6 mph. Thanks.

I have my parts! I thought once I got the clutch and read the manual I’d understand all the adjustments. Boy was I wrong. It looked like English anyway.

The Malossi clutch comes with yellow arm springs. Are these the same as the yellow springs in the clutch arm spring pack?

Any suggestion on which springs I should try first? (White, yellow, red)
Should I make any adjustments to the clutch or leave it as it came from Malossi?

Thanks
JD

I would start with the yellow springs and move the tension blocks back 2 teeth to put a tad more pressure on the springs. the yellow ones in the pack are the same as the ones in the clutch. then you can change the weights on the back and change the springs to suite your needs
