Thanks for the information.. I just got my 40 toothed sprocket and hub adapter today and I can't wait to install and test it out..

+pdizzy310 You're more than welcome! Feel free to post some pictures of your build along with a little description on the SCC Facebook page at Facebook.com/sccmn. Happy holidays!

Thanks for all your knowledge on motorized bikes! I just built my first one. Getting itchy to do another one soon. 😀👍🏼🚴

What about going from the 10t a multi speed sprocket mounted on the left side. The I have a big 51t on my rear. I i was thinking of mounting a 3 speed multi gear for on my left side. I'm doing it for a better chain alignment. The one I have that I am looking at using has 42, 34, and a 24. So my question is what would be the best way to set the chains up. I'm not sure looking for very low end torque but a speed of around 40 - 45mph so I can keep up with the flow of traffic. I BTW let me add that the motor is I'm going to be using is a Subaru Hurst Ex17. it has a specific OEM for Hurst Jaws if life is and it was never used before specs say it puts out 7 hp @4000rpm I'm also going to be using the juggernaut tav clutch system. So I was thing coming off the tab 10t to the 24t. I then chain from either the 34t or 42t to the 51t on my tire which is a 26 x 3. I but when fully aired up its actually a good 27" from pavement to top crest. I till I add my 165lbs then I think that brings it back down to about 26.5.

Thanks for the advice and the video. I'm 360lb 6'2 I have a Phatmoto that I'm switching the motor out. I live in an area that's hilly. should I jump up to a 52T or??

Hey sinister, I am just a few miles south of you. I’m in owatonna Minnesota and I’m trying to start a motor bike club in my town. I’m also looking into getting the 2020 phatmoto rover, what do you suggest for hearing options? I’d like to get the bike to go about 40 mph at minimum

I want all low end torque for hills and some off road! I've just got a 10 tooth max torque tooth centrifical clutch for a 415 chain not installed it yet. I want all torque and bottom end power around 10 through 12 miles per hour is great. Don"t care about top speed. I have the 2019 phat moto bike what gear tooth on the jackshaft do I need and is available? (8 tooth or less)? Possibly could get another jack shaft sprocket cut centers out balance and reweld them. I have a 50 rear sprocket with a 415 chain. On the technical side I don't see the distance between the bolts with online to install the rear sprocket. If I have to I could take two sprockets cut the centers out check runout, balance then weld them to make one sprocket work. since their seems not much availability for the phat motobike. Course if I go this route I'll have a machine shop to cut them. I like to be able to pedal the bike with engine off also to get a good workout. I know one of the 212 engine swamps would do the job. I'm not sure if you can still pedal the bike without hitting the sides of engine with the 212. Thanks

I have an older mountain nice mountain bike with front for with shocks, wheels, and and gear changers. I have been thinking of buying one of the frames with the gas tank built in and installing a 4 stroke kit. Am I missing anything with the setup described with shift kit, non coaster brake hub?

[@Wynne3000]

Do you think you could make a video on rebuilding and cleaning the Huasheng 4 stroke carburetor?

[@sinistercustomcycles110]

Thank you for the suggestion Edward! I'll definitely keep that in mind. To be honest though if I do that video it won't be for awhile but I will definitely put it on the list. Thank you again and happy holidays!

[@raymondborkowski4290]

Wish someone made a small torque converter for this setup.

Where you at on Facebook?

[@sinistercustomcycles110]

A lot of the bike frames I have seen with the built in gas tanks are single speeds which means the opening in the frame for the crank set is going to be 2". Bikes with gears on them have a much smaller opening for a completely different crank set set-up. I'm not 100% sure this combination would work. If anyone other viewers can voice their thoughts that would be greatly appreciated.
