Great vid! I also see lots of people just "throwing pistons in"...its great that you brought to light the importance of ring end-gap.On a side note though,i usually measure the bore before measuring end-gap and measure end-gap where the bore is smallest....usually it is smallest and least out-of-round just above the transfer ports or somewhere close to the center of the stroke.just thought id mention that.thanks and keep bringing on the great vids!

im no master mechanic and I'll probably catch hell,but i thought that checking ring gap was a absolute no brainer?! thanks for all your videos..love this channel.

Love the tech vids Louie! Especially the Polaris and Landcruiser ones!

I feel you with the rain. Down in Mn we just barely get enough snow to ride then it rains .. sad sad time

Thanks for the info, i like these kinds of video.

Your kids a good camera man

Vary nice love your videos!!!👍👍👍

Maybe mention there is such a thing as a ring filer tool. keep up the good work!

ring end gap thats ok but now when ur done for the gap you have to file the end so you have no sharp edge (debure)

thanks for that

What kit do you recommend for the 800 cfi ass far as reliability goes. Have you tried the ssi kit? Thanks

Next time if you are doing big bore, maybe Terra Alps racing?

I saw you in Carlton place today

Nice toque I just work with Chris Evans down in Cranbrook

so Kelsey switched from the German pistons to wesco?

Do you have to do anything cylinders before putting in rk tek pistons. Thanks

Is that the kit that comes with the spacer?

Do you still have any of the iqr's?

What year is your rev

Where is that chainsaw mounted on the bicycle???? LOL

Kids do better than the adults on the camera work!!!

How would I know what size gap to go with i have a 2010 Dragon 800 rmk ?

if you had a tight ring gap, would you have an issue right away? or could you run it hard for 1200miles and not notice a thing?

do you know if the gap needs to be smaller or larger with a turbo?

How do you like those RKtek pistons, are they holding up?

How long did this piston kit last?

Did I miss something? Why the new top end?

whats up witht he camera... its only playing in 360p

hate to be that guy.. but technically your doing it wrong.. if you apply side pressure to the ring it can get warped. better to use a file and pull it back and forth across with just the ring tension or use the tool made for it

Should file from the inside out, if that was a moly ring that would be destroyed now. Not trying to sound like a douche Louis. I love your videos.... You should get a ring file machine, you do enough top ends.
