Thinking of experimenting a bit, 3-3 wrap on secondary and ton of weight in the tip?

Yes

Aluminum with thin washer , you'll be surprised.

Just have to try it and see. Some Vipers like it and some don't.

Most I have seen like a little weight in the center.

So what should I use on my sled. I got mcx270 and have the HHY68 weights. Should I go for so much weight I can in the tip? what does the middle weight do? I'm goin to field test the weights tomorrow and trying to get it close to 8700

Start with 3/8 steel bolt and thick washer in tip, 3/8 aluminum and thin washer in mid, and 3/4 set screw in heel. Check and adjust from there. If you are still high on top end add to tip until you are at 8750. Then add to mid until you get to 8700. I have a stage 1 OSP and i am 58g base, 7/16 steel tip, 3/8 aluminum and thick washer in mid, 3/4 setscrew in heel with O-P-O spring and 46/40 helix set at 6-1 for reference. PM me directly for more info after you try this if you need more help.

I just installed a Big Venom kit on my stock ltx se. No studs. Will the factory belt work okay? I've heard some guys are switching to gates carbon fiber. I'm sure this has already been discussed at some point but I didn't want to weed through 40 pages of threads

If you want to run the 8JP equivalent (stock belt).....use the gates 40C4313

This is a carbon fiber belt. This belt will last much longer than the yamaha belt

 

[NOS-PRO]

and grip better......

Stock belt will work with the kit, but washers may be needed as the rpms will be higher with the stock 8JP belt due to just a little more slippage than the Gates belt.

I've installed the carbon fiber. 40c4340. (8dn length) I've added shim washers and the belt deflection looks good.

Hey guys, new here. Im pretty much doing the same install. TP big venom, gates 40C4340 on a stock stxdx. Just wondering where you get these shim washers for the deflection ajd. Or will any equal washers do? Blew my budget for now cause picked up the shaper bars too. Cant afford the new belt adjuster...lol. Thanks.

Dealer or Hardware store. Just make sure they are the same thickness. 1mm thick.
