What a great uncle you are. You are sharing your knowledge and building confidence in your nephew. I can see a lot of youths, like your nephew, watching your video and being encourage to try this themselves; "It is easy, and you can do it." is all they need to hear. You are very direct and clear in your explanations, which is critical; and you never talk down to your audience, even when talking about the most simple of mechanical concepts. A commendable job.

[@rafm5333]

Great video, clear and informative, thank you so much I’m looking forward to installing these parts

[@vaporistic4203]

It's crazy how there is an air filter, but it needs spray to filter dirt. Ironic but makes sense because the spray is sticky and will sure catch those little particles. By the way awesome video I just traded my 250 dirt bike for a Murray full suspension dune buggy type go kart and it already had the stage 1 upgrades! I think it has a different piston too. Have a good one😁

[@DonKeyhole1]

It sounds and moves like it should be black with lots of red accents. What a great sound that mod makes.

I am 54 now, when i was 44 I got the urge to go kart race, did so for 4 years, A 6.5 predator engine can put out 15 -19 hp and turn 7500 rpm alot easier than you think, If you break in the engine and do it right, those engines will last a long time and be very reliable

[@KartFab]

yesir. Ive got one that im working on that will do just that!

I'm 14 and have been kart racing since I was 7 and those Motors are trash

[@715101]

Cliff P if your sure the tap and bolt are correct you could use it, I would prefer (if possible) to just clean it by running a bolt in and out with some penetrating lube to avoid the chance of crosscuting the treads with an aggressive tap As for mods you can buy a stage one kit or make your own what you need to do is remove the governer gear and arm make 1" diameter exhaust about 350mm long expanding to 1.25-1.5" 100mm-150mm long at the tip, drill the carb main jet to 0.8mm and add a high flow air filter and adapter (these are reasonably priced) this will give you a decent power increase I would also add additional crankcase ventilation and filtration system

[@montypython8978]

Hi, love what you do and full respect! I have been building high-performance motorcycles since the 80s. I happened upon a free Subaru 170- 6 hp setting for trash pickup on a stump grinder..Wow, you have got to do a build on one of these! Overhead cam, giant intake and exhaust ports, high-lift cam and a big-bore short-stroke with a hefty con-rod! It is built like a Honda XR engine! If you want, I can share some pics! I plan to get 15+ HP out of this reliably! Also, Super-lightweight.

[@alexcandrilli3373]

I have one on my mini bike and your right man that subaru is a beast...i would like to mod it out..let me know if you have any advice on that.. thanx

Typically that comes with the kit. I buy mine from ombwarehouse.com and it's always in a baggy tucked inside the filter with the filter adapter nuts and the hex screw to hold the bracket in place.

Where can I get 5 or 6 inch rims for a minibike? I've been looking everywhere for them but can't find it & how do I know witch ones will fit with the rear sprocket that I need? I think I read on your site to get a 10t clutch and 420 chain with a 50t rear sprocket to go with the stage one set up. That's what I want to go with but can't find rims for it. The ones on the mini bike I'm restoring are rusted out where it had holes in it.
