Default '16 ZR handlebars slipping and shock upgrade

Hey HCS, hope everyone's summer is going well. I have two questions:

My bars periodically slip/ fold downwards/ towards me when riding hard and pulling on the bars. I have the riser (stock 4.5") bolts tightened as much as I dare, but it still slips once in awhile (at the base of the riser where it meets the steering post). Does anyone have a tips to make it rock solid and stop slipping?

Also, I have searched in the past but have found a myriad of suggestions regarding what to do with the non-QS3 center shock. I'd like to upgrade it to perform better or on par with the rest of the QS3s. Any and all suggestions welcomed. Thanks!

I would say the bolt aren't tight enough on the riser, both upper and lower... All 8 bolts need to be very tight.

On the shocks, order the aftermarket spring from the Yamaha site that is availble for the sidewinder. It makes a world of difference. I will see what I can do to get you some contact information.

A thousand times order that spring! I have one and it is undeniably needed. The stock one is a Textron special, they just kept it the same as the lighter 800 version.

Is that shock something recommended for the 2 strokes also or just with the heavier 4 strokes?

I saw this thread and it reminded me that someone I ride with lost 2 of those handlebar bolts last year, so good idea to keep eye on them. Ended up riding with 3 and 3 until we found a hardware store.

Not a bad idea to use a little blue loc-tite on the bolts.

I'll will definitely be ordering that spring. Also, I use blue threadlock almost everywhere on my sled. The problem isn't that the bolts have loosened, but are just not clamping tightly enough. They feel like they are going to strip the threads in the aluminum riser block.

Are the two sides touching each other when you tighten the bolts? If so, an easy fix might be to take .010 - .020" off one side of the clamp. If they are not touching each other, you're gonna have to create more friction between the handlebars and the risers somehow. Create some serrations on both. Multiple ways to do that. A good sharpened chisel could create "grooves" (aka serrations) on either (I would do both) if done properly. Then, use some kind of Loctite when you're putting them together. Clean both parts well and use retaining type Loctite.

No, the caps aren't touching the riser block when fully tightened. I think I will do what you guys suggest and notch the bars where the block mounts to give it some bite.

Regarding the Yam spring: is that a stock part or does anyone have a link on where/ what to purchase?
