Thanks for the video 😃👍

[@buckboula1304]

Yeah I had the same problem with that sprocket also but I did grind down that sprocket like you said you started to do but it works great now

[@engineunknown2]

Right on

[@buckboula1304]

I noticed that your post is showing how you ran the chains on your crank an the only place where I need a tensioner was on the chain going from the motor to the crank. My question for you is; how do you start it now because when you engage the clutch by pulling in handle you now can pedal like a regular bike, but if you popped the clutch like normal, I noticed that the only change is now when you pedal it's now attempting to kick start the motor instead of just engaging the clutch.

[@engineunknown2]

I just use the pedals like a kick start

[@michaelbrinks8089]

Does your air filter stick out too far on your carb/build?..... would you have got an adjustable 45° air filter instead? Dunno if I should just get straight filter on vm22/G2 reed kit or keep looking for a 45° for 29in frame. I'd love a 29in full suspension frame with shock mounted in rear, jackshaft kit & some 2.750 wide tires to soak up bumps.

[@engineunknown2]

No I haven't any trouble with the filter it still pedals just fine. I just like to use what I already have but if did i have one i probably use 45' air filter

[@michaelbrinks8089]

@@engineunknown2 thanks for reply.... Now I know the straight filter will be OK if I can't find a kit with 45°

[@engineunknown2]

@michaelbrinks8089 ya they are hard to find

[@michaelbrinks8089]

@@engineunknown2 I bought 2 Blackburn 29in tires from Walmart. I just tried to change my front tire & realized the Chinese tire factory literally make the tires too big. It's like 30 inch in diameter instead of 29in and falls off the rim lol....At 1st I thought my rim wasn't wide enough but even if I had a wider rim. They're too big in diameter.....Unreal that the factory could screw up that bad.

[@engineunknown2]

I'm not sure what bike you have but maybe Walmart 29ers have slightly bigger rims on their bikes and walmart makes the tires that size just for them I'm guessing. I have always gotten mine from amazon or ebay.

Is the Phantom 85 bike still running? I got one of those and I'm really dissapointed with it's speed. Only 39 mph on a 36t sprocket stock. How did you get yours to 50? I want to do the same

[@engineunknown2]

Ya when I got mine it did 39 mph and right after it snap a ring on 3 ride so I cleaned all the ports new piston rings and put a pz19 carb with a g2 reed and jog pipe and it did 50mph and it was good till I decided to go faster it hit 58mph but then melted the piston so I'm thinking about trying the v3 cylinder out

[@viliuspra0314]

how did you center the sprocket you put on instead of the beach cruiser one?

[@engineunknown2]

All I did was measure the diameter and find center. Then I measured where the bolt holes go

[@johnrutledge3892]

Thanks

[@engineunknown2]

No problem

[@brandonwaughtal6391]

Where's the follow-up video? Did it work out and shift okay? Thanks.

[@engineunknown2]

I never had a chance to do a follow-up video, but that kit I had at that time to me it wasn't worth it

[@brandonwaughtal6391]

@@engineunknown2 ok thanks for replying. I'm new to this and I'm trying to figure out if it's worth building one? I need it Reliable. Lots of videos about jackshaft kits put never a follow up if it works out or worth it. Thanks for the help.

[@engineunknown2]

@brandonwaughtal6391 ya if you won't to have a reliable setup I wouldn't run one there's to much moving parts and the stock bike chain and rear wheel don't like it

[@mudriping]

Where did you get the kit?

[@engineunknown2]

I got it of ebay

[@garygrey8573]

Just a heads up... You can use the tensioner out of a clothes dryer.

[@engineunknown2]

Ya I have done that before

[@leonardarola]

Bro, you, sell me your jackshaft kit or trade me for a newer version. I need YOURS.
