Pro Tips Prepping My ROK Shifter Part I movie

With the start of a new season upon me, I decided to drop my trusty but underpowered Honda ProMoto shifter kart engine for the Rok shifter engine. Join me for part 1 of this two part series where I am introduced to my new engine and begin installing it on my kart.

The engine sounds aggressive ❤

nice motor package. i did notice you didnt have to change the rear sprocket gearing.

[@RKSiler]

Yes, the rear sprocket did not change but the front sprocket did...on the Rok, you run (apparently) a 17:25...other tracks might vary +/- one tooth on the rear sprocket. Thanks for watching!

Good info! I’m about to purchase a new ROK shifter package myself. Look forward to seeing part 2!

[@beginagain8101]

Hey, thanks for watching and best of luck with your new Rok shifter! I'm pretty excited about mine, and you will see Part II on Wednesday evening of this week.

Can’t wait to get back out there! So glad to see a new engine package for you! Great Video!

[@beginagain8101]

Thanks Casey, I appreciate it! It is definitely a big step in the right direction.

[@danagibbons99]

Glad to see your update !! Congrats. Interested to see the performance improvement !!

[@beginagain8101]

Thanks Dana, pretty excited to get this new engine! I will release Part II of the build/installation next week, and then the next video will be track testing the new engine. Stay tuned, should be interesting! Thanks for watching!

Really enjoyed the content. Is the motor broken in?

[@jasong712]

Great video. Mikes a good dude!

[@beginagain8101]

Thanks so much! Yes, Mike is a great guy, he has been super helpful!

[@gregoryjones9754]

Totally enjoyed the content. Really interested to see how Mike tunes it. Is the motor broken in?

[@beginagain8101]

Hello Gregory, thanks for the very kind words! The engine is now broken in, but we haven't really had a chance to tune it yet due to bad timing and bad weather. That will soon be another video, however.

[@sw653j]

Now I'm confused, after the KZ vs vid. I was ready to buy a KZ!...LOL

[@beginagain8101]

LOL! The KZ is faster but I think will require more maintenance than the Rok, so I went with the Rok

[@twinturbo3470]

Hey any idea how a Rok compares to a TM-R1 in terms of reliability, maintenance and performance

[@RKSiler]

Thanks for watching this video and great question! I really don't have any experience with the KZ (TM-R1) so I went to several friends of mine who race both and what I found was this: The typical time for a top end overhaul on a Rok is 10 hours, with 20 hours being about the norm for both a bottom and top end; the KZ engine is about half that in terms of time. There is no doubt the KZ is faster than the Rok; the longer the track you are on (either longer straights, faster turns or both) and the KZ will walk away from the Rok. That said, I love my Rok-it is plenty fast and very reliable, easy to tune the carb, etc. When you run in a class that is mostly Rok engines, as I do, then you have plenty of people to race against.

@@RKSiler thanks for the reply, great info

[@RKSiler]

@@twinturbo3470 Glad I could help! Two other data points came to light after I replied to you. The first is that at the really big races (like the Super Nationals), the KZ guys are running on the ragged edge of lean (almost to detonation) and for safety's sake, they do a top end rebuild prior to the Final because they are not sure the piston can take that kind of abuse for an entire race meeting - that means a top end every 60-90 minutes of running. And, apparently the thing to do is run a Lambda sensor instead of an EGT since the Lambda sensor is way more accurate and will allow you to figure out the right main jet, low speed jet, needle and needle setting for the entire track, not just the longest straight aways...admittedly, at this point, I have NO idea what that means but will do some digging and pull together a video on the subject. Thanks again for watching!

[@eduardoramos2734]

I have a question which one is better rok or iame I use iame and a champion in it just want to know which one is better.

[@beginagain8101]

Hello Eduardo, thank you for watching! I have not driven the IAME, so I am probably not the right guy to answer that question. I will be posting my video on actually driving the Rok in hopefully two week's time, so please keep an eye out for it. The second part of installing this engine will be released the middle of next week.
