So I tried to post twice already with a video, never went through, I got a 21 cforce 600 I picked up needed a rebuild after the last owner swamped it bad. Everything went fine and ran well, after a month or so it started making a loud buzzing noise from the left side, so I figured it was stator related, took it apart and it was fine, charging at 14.2 and not coming apart and nothing rubbing on flywheel. Only other thing I saw in there is the one way bearing for the starter so I replaced it. No change. It's only at first startup and lasts a couple minutes and stops but very loud and annoying. I wish the video went thru. It also may be temperature related because the one time it didn't do it was the 1 warm day we had here in mass. Any ideas would be greatly appreciated, thanks

Hi guys, my brother got a hell of a deal on a 21 z500 knowing it needed an engine rebuild, only thing is that he's getting mixed info when he searches for parts, does anyone know if a 21 is a year of its own or are the engine internals all the same? I was under the impression they were the same 17-22 or 23? Any input is appreciated, thanks in advance and happy thanksgiving to all

Cutting the head off won't do it, got to cut them at the bushing, plenty of room so you won't hit the arm or the frame, cut pretty easy too, only had to buy the 2 bolts and sleeves on driver's side, others came out with some work but are in great shape after cleaning them up. I just got the bushings yesterday along with 2 left ball joints and L&R tie rod ends. Also decided to take the rear apart again to re-grease. Then I brought all the a-arms to work to paint them all, getting a little rusty and starting to show their age, so I probably won't have it together till next weekend. Cold snap here in New England anyway, suppose to be below zero and my heat in the garage sucks

So I soaked them down for almost a week and even removed the grease fittings and drilled 1/8 in holes through the sleeves to the bolt and sprayed it with PB, WD, liquid wrench and anything else I could find-wouldn't budge, had to cut both on the left side. Got the right side out but not without a fight. Hopefully will have everything I need by the weekend, gonna try the blue polyurethane bushing set from Curren rv

I'll do that, I'm in no hurry, and as far as lazy days suggestion, that's a good idea too, unfortunately I took it apart at home not at work and I have no welder here. Was hoping for a couple hour job, thanks guys, I'll get back to it during the week, don't really want to cut anything if I don't have to

Ya, nut came right off, seems the bolt is stuck to a sleeve inside? I did the rear bushings when the machine was about a year old, very simple, front lasted till now, probably shouldn't have waited this long

17 zforce trail control arm bolts spin very slowly with impact but won't budge, tried a little heat but made no difference, any suggestions? No way of getting a swing at the nut side

Hey guys, many thanks to all that have posted on there cave mods, diced mine up this weekend and it made for a much easier job knowing what you're in for. I just wanted to add one thing that I ran into. For those of you with full doors, check th alignment before welding. My cage went boing when I cut it and the doors dropped quite a bit. Simple enough, I just ran a ratchet strap down to the hitch and cranked the rear of the cage back. Just a quick check could save a big headache later, thanks again, great info here

Nicely done sir, looks bad-ass, I won't ask any questions, I'll wait for the write up

C1 worked good but I did end up going with B2 after a bit of riding, its all personal preference and how you ride imo, and I did take the advice of other members here and used the pennies to figure out what I wanted for weights and was able to find 14 g weights from the can am guy. They were very hard to find at the time like everything else. They seemed to grab a little quicker than I thought they should so I drilled the center slightly on all evenly using a digital gram scale. Comes down to trying different setup's to see what you personally are happy with. Pretty sure my final weight was 12.75g, it was a while ago, it's in one of the threads, good luck with the new machine

I put a better one under the  pictures category here a while back

This is the best picture I have, wasn't naked too long before I wrapped it, I think by the end of this season I'll peel it off and go back to all black

Thanks guys, some good info there. Looks like I got some work ahead of me, now all I need is some spare time. I'll post if I find something, I think I'm going right to the injector first

Yes, valves were adjusted on all, they were all off, seem to run better and quieter. Did that over the summer. Now my next question is, what kind of scanner can I use? We have a new million dollar snap-on at work but I thought I read it could ruin the tool if plugged in to OBD?

Hey guys, hope you all had a great holiday. I know I've read a couple posts on this but not sure if anyone had a fix. We have 3 cforce 600 and 1 500Z in our family, one 2019 600 two 2020 600 and the zforce is a 17. The 500 fires right up no matter how long it sits or whatever the temperature is. All of the 600's will crank all day long and will not start unless the key is cycled 3 or 4 times as soon as the temperature drops or if they sit for a week or so. Once they start they're fine. I don't understand, key on fuel pump runs then shuts off, that means there should be fuel pressure, why won't it start unless cycled? Not really a big deal but the wife just don't get it, I can see me buying a starter soon if she keeps it up, thanks in advance for any ideas or fixes
