The issue is that at random, the bike will just continuously crank and not fire. It takes several key cycles/pump primes for it to finally fire.

I have installed a $400 Optima battery in it, new spark plugs, every single relay in the fuse box is replaced, a brand new fuel pump and fuel filter, and I located every ground point on the chassis/cleaned them and applied di-electric grease.

The battery WAS an issue for a time, because whenever this would occur I would get about 8 or 9 different "low voltage" codes for various different parts of the engine.

The problem went away for a while, but it is now back (Without any codes though) It happened to me on the trails in West Virginia about 10 miles deep in the wilderness. We pulled off to use the bathroom and grab a snack, so the machine was definitely hot. Sat for about 10 minutes and went to crank it - Took 3 key cycles to get it started and me sh*tting my pants thinking we were gonna be stranded.

By all accounts, it doesn't appear to be an electrical issue and the battery is DEFINITELY strong enough (It's an Orange Top with Optima CPR)

What it seems like to me is it's losing fuel pressure, and fast. When the issue occurs, you can hear the engine sputtering and trying to fire but it won't until enough fuel is supplied.

I had considered replacing the injectors for a while, but if it were an injector it would still fire one cylinder and just run rough as hell right?

Has the check valve failed again? Is there an upgraded or aftermarket fuel pump I can put on this thing?

I love this machine and have invested a ton of money in it - No more warranty, so I am on my own to figure this out. The parts cannon gets expensive.

Thanks

I know this thread is very old, and I apologize for digging it up. I have a 2022 ZF950 Gen1 with this exact problem, but here is the catch:

I removed the front driveshaft and drove the bike around to confirm it's the driveshaft. It has too much play in it and when coasting from 20mph down to about 10mph it makes a hellacious rattling sound only in a certain RPM range. A guy on FB said this was a manufacturing defect and CFMoto replaced his, but mine has been out of warranty over a year now. Has anyone been able to shim this out, or does anyone know the part number of the updated shaft that will fix this? It's driving me insane.

2022 950 Sport non-HO/EX, just regular model.

My issue is that the front diff is in 4WD, regardless of the icons on the screen or the switch position.

The actuator is working - It makes noise and doesn't sound like it's bound up.

This is most likely my fault, because the ORIGINAL issue was that my front diff started leaking gear oil around the 4WD actuator seal.

First removal - Replaced o-ring, re-filled with oil, stuck in 4WD

Second removal - Fixed the 4WD issue (Slider was too far over on re-assembly) but upon re-assembly, the new o-ring tore and it leaked again after about 6 months.

Third removal - Discovered torn o-ring, replaced, re-assembled - Now it's stuck in 4WD again.

This time, I am buying an entirely new actuator and o-rings, as well as removing the winch to get a really good shot at it.

Has anyone else had this issue? It's so annoying. The machine is a demon other than this really annoying problem.

I just got a further update on the ETA with these and they will be available from around sept. oct.

Hey, just checking in on these. Are they ready for orders yet?

I got my blower installed!





Fit like a glove!

Just wanted to say thank you for this idea. I bought the exact same blower and 2 Fernco fittings from Lowe's. I am curious to see how it's holding up for you? The Ferncos are not rated for much heat at all. I'm putting some heat tape over mine just to be safe. Also installing a temp gauge. It was a PAIN to get the CVT intake tube off - I had to remove the entire back of the machine lol.

Sweet! Thank you so much!

Has anyone done this before I start digging into it myself? Which hose is which on the canister?

Literally only 3 miles on them. No issues, they will just collect dust. Make me an offer. PayPal preferred.

I cannot find guards for the front/rear A-Arms anywhere. They have mounting holes there for them already, but I can't find anything online. Has anyone had any luck? I don't need a whole skid plate setup, just guards for the A-Arms. Thanks!

We will have some soon for the ZForce 950 Sport. I have not got an ETA yet though. There will be front and rear A-Arm guards that you can buy as a pair or a full set, a center skid plate, footwell protection and also a front bumper.

Thanks, Mike.

Awesome!! Any idea on how much they will be?

Ricochet has a set for the 1000. Maybe they can be adapted/modified to fit the 950.

I called them and they for sure won't fit. They aren't long enough

I don't know if it's similar to the 2021 model, probably is, but I found mine underneath the front plastics. Pretty much a full disassembly on the front to get at it... All of the plastics, side panels, gauge cluster... Really a PITA

I found what was causing mine!!

Thanks for these links! I am trying to find the LH COVER, ENGINE - PDS#-044051-6000 for my '21 600 Touring. Looks like I'll probably have to order it from China ugh.
