Glad I could help. I was lost also when doing the swap

I ran the stock belt and it seemed fine. I don’t think that small of a difference is going to matter. It’s not like it’s a 80 mph sport machine. Lol

I sold it about a year ago. I liked it but in stock form, the predator was just not reliable for me. The carburetor would get out of tune very easy and would not run right. They can be good engines if you want to build them but in stock form, I was not very happy with it. If i did it agian, I would rebuild the stock engine, put a honda in it, a kohler, or maybe a Duromax engine. Not to say all 670s are bad but I did not have good luck with it over the long term in stock form.

@@atvrepairsandmore2482 hey, thank you so much for your reply! I appreciate your very detailed feedback! Going to have to give this motor some serious thought, The thought of doing a complete rebuild and then throwing in a mediocre engine... Definitely have my concerns. Thanks again for your reply!

@@billmers3219 Just because I was not a fan of mine does not mean yours is bad. I do not want to give the engine a bad reputation but that was just my honest experience with it. If you join the predator 670 group on Facebook, there is a lot of useful information on there. Many people kind of feel the same way I do about the stock engines. Most of the issues can be solved with a aftermarket fuel pump and oem honda carb.

It’s doing alright. I’m having carb issues since it’s a predator. I need to put a new carb on it. Otherwise it’s been good

@@atvrepairsandmore2482 did you consider using the original mule carb? Those seem to be pretty good and I believe have the same bolt pattern.

@@buddywebser7498 I didn’t check to see if it would fit. Not a bad idea though

No I do not. Try to adjust your shift cable. If that does not fix your issue then it is probably a internal transmission issue. If you are having cold start issues, do a valve adjustment. I have had many Kawasaki ATVS I have bought dirt cheap that would not start or were hard to start because the Kawasaki engines are bad about the valves tightening up over time

Colton Dieringer Thanks. I’ve been meaning to adjust the valves for a while. Should be an easy and quick service.

wmkess it’s very easy. Just buy a feeler gauge on amazon for $8-$10. I’m sure there are plenty of videos on how to do it you have never done it before or you can look at the service manual if you have it

@@atvrepairsandmore2482 what pulley did you use for the alternator? I'm doing this very same swap on mine now

I think the 670 might be to big for a 610. I think a predator 420 would be best for it. I have heard that the 610 factory engine roared the opposite direction but I can not confirm that for sure

I mounted my 670 on a 2500 Mule.Heard the direction of rotation was an issue as well.Fortunately I didn't have that issue.The output shaft on the predator rotates counter clockwise as does the shaft on my transmission. Put your mule in forward and see which way the trans pulley rotates to make it go forward.

Thank you! Good to know

Know which wire kills it?

If I could do it over again, I would have rebuilt the original engine or dropped a Honda engine in it. The fuel system on the 670 is awful. You have to swap out the pump and carburetor just to make the engine somewhat reliable. I got tired of messing with it and ended up selling it. It would never run correctly on the factory carburetor.

@@atvrepairsandmore2482 Cant even find a Honda and the ksaki is trashed. Ever use the duromax engines? (Amazon has them, another clone I'm sure) 713cc for $991 I figured the carbs would be the issue as they are not designed for foot pedal control, I'm amazed the k saki works as good as it does. K saki carb mount to these clones? Does the clone engine carb even look like the k saki carb? I haven't seen one as i don't want to buy the engine till I think it'll work worth a darn.

@@Freefamable I have heard good things about the duromax. I believe you can buy a OEM Honda carb that bolts on to the predator. If you join the 670 group on Facebook, there is good info on there

I just got it as close to the stock distance as possible since it’s a stock belt. Best thing to do would be to buy one of the weld on plates that allows you to adjust the distance. As long as the belt is wearing properly and the clutches aren’t catching at idle then you are good

I used this and welded washers on the inside to make the center hole smaller

I will have to go look at it because I forgot what colors were what. I had them wrote down but I can’t remember where. I can take a look tomorrow and let you know. Glad you enjoyed the video. Just trying to help people out because it’s stressful doing it without a guide

Hi I’m doing the same but I don’t know the year of mine’s it’s marked mule 550 on the hood how can I check?? Thanks

I really could use your wiring diagram.im doing the exact same engine swap

Could you send me a message I’m Doing the same swap and have some questions

I never had a problem with it. As long as you are not submerging it in water, you should be ok

@@atvrepairsandmore2482 awesome thanks

I’m just outside of Houston and I do occasionally work on other people’s machines. I won’t do custom engine swaps like this but I can work on stock machines and things of that a sort

I used a comet 780 which is designed for a 1” shaft. Best thing to do is to get on a Facebook group for that engine and ask what other people have ran on similar projects. I know for the 670 that the comet 780 is the best option for most applications. Comet should make a clutch for the 459 also

You can go ahead and ask me here. I’m pretty good about replying on the comments

Still like the swap ? Thinking of doing the swap with a van guard and and a kit 6x6 conversion place
