Just getting ready to do the same thing on my 660 Grizzly, the video helped my confidence level a lot. The only thing I would like to have seen you spend a little more time on is the timing sequence itself and how to time everything, timing marks etc.

Glad it helped! We already broke it again so I’ll be making one more video on this soon. We ride stuff hard around here haha

How did you reinstall the gear with the springs on it behind the flywheel??

[@flipposgarage]

You have to make sure you keep the springs in place and the springs slide into the recessed slots on that gear and that lock ring holds that gear in place. Does this help? I’ve been making sure my video skills are better in my new videos my apologies.

Hey man i gotta few questions on how you did the timing I have one almost identical and im having timing issues

[@flipposgarage]

I’m just now seeing this bubba. Did you get it figured out? If not, how can I help?

[@shawnwilliams7917]

@@flipposgarage no I didn't get it figured out I've almost given up on it

[@flipposgarage]

@@shawnwilliams7917 don’t give up bubba just take a breather that’s what I have to do sometimes step away for a min. What questions did you have for me, sir. Maybe I can help.

[@flipposgarage]

The timing goes like this, make sure piston is at top dead center (piston is all the way up) when you install the cam and cam gear there are two dots on the cam gear you want these to be exactly level with the deck of the motor (dots parallel with top end deck) make sure valves are closed and the lobes of the cam are facing down and install the timing chain. Also very important, u can have ur timing right and think it’s off if your valve clearance is off by even a small amount refer to video for this. If your timing chain is even one link off it won’t b in time. So make sure timing is good then check valve clearance. If you still have trouble email me I’ll help further. [e-mail]
Lmk how everything goes brother!

[@giovannimartinez9547]

​@@flipposgarageWhat do you mean by valve clearance if it is shifted?

[@RevDevGaming]

You didn’t really explain how to remove and install tensioner and set the tension back.

[@flipposgarage]

It’s because it’s just two bolts to remove/install and it can only be installed one way. Once you install and turn it ,it sets tension automatically with a built in spring. Make sure you have installed everything and set your timing before installing tensioner. Hope this helps.
