gearing

Ready to order sprockets for the jimmy gote. 13 hp, with jackshaft and torque converter. Be used for trail riding mostly, not really interested in high speed. If it does 35mph I'll be happy. Needs to be able to carry myself and a couple hundred pounds of elk. I was think of a starting gearing...

Just finishing up my db30 build and wondering what size rear sprocket I should run. I'm running a 6.5 predator with a stage one kit, 15x6x6 tires and a 12t clutch. Thanks

What is a good gear ratio to run for mini bike Now is 14.5 tire 35chain 70th rear and 12th clutch. I topped it out today at about 39mph 5280rpm when valves floated, im running a 212 predator hemi with header rejeted and pod filter, have billet rod and flywheel on the way mod2 came and heavier...

Hi OldMiniBikes. I just purchased a tav 30 Chinese copy with a 10 tooth sprocket. For my off road go kart. So at the moment my gear ratio is 4.8:1(10 drive sprocket and a 48 wheel sprocket) with a 13" tire. Driver and kart weighs roughly 370ish lb. At the moment on hard ground it hits the 4500 max...

On the mini bike I'm running a TC with 19" tires and a ration of 7:2 and it rides good, take off is ok but takes awhile before I hit 40mph. From what Iv read the TC needs to be able to go into overdrive so a 72t worked for that in the rear. It's a cruiser so I'm happy with that. This trike...

Hello all, First post so apologies for the elementary question. Stationed in Italy, bought a Stock Motovox for my 12 yr old son. He liked it but quickly grew bored with it. Got a Predator motor and livened it up so much, he's scared of it now which is counter productive. I have 11t, 12t...

I may have found an issue with why my trike isn't revving like it should. My jackshaft is bent after going off a jump and bottoming out on the jump with the driven. I thought it just bent the driven so I replaced it. But after jacking it up and running it. I could see the whole jackshaft was...

need help with 1/8th or 1/4 mile gearing. i dont have the cash to buy 20 different sprocket combinations. i have a taco minibike with the jack shaft. i do not want to eliminate the jack shaft. any help will be greatly appreciated

I'm building a T Bob frame with 50 in. wheelbase, 25hp clone, I weigh 215lbs....will be running 1/8 mile or possibly 300ft. I need a starting point for a final drive ratio or sprocket sizes. Haven't made the purchase yet, buy will prolly run a Bully 2 Plate clutch and shoot for a 4000-4500 rpm...

Hello! I'm really new to mini bikes and everything. I got this one as a project for school. The guy said it was a vintage 1970s trailhorse. This one has the springs in the forks but no springs in the back. Talk about a stiff ride when your offroading. I have a few questions for some people who...

now that its done I guess, might as well show it off. I introduce "Makin' babies cry"...and the purists as well :-) Its built for the Lone Star Roundup races in Austin and lived up to its name. I have since changed the pipe to one for more torque and dropped the gearing down from 11.8:1 to...

need some gearing help for 100 ft drag :thumbsup: have a 13 tooth 2 disc reaper clutch with stall set at about 3500 rpm and a 66 tooth split rear sprocket with jackshaft in between trying to figure out how to set it up to jump out of the hole and pull the whole way hitting max at the line . any...

Ok, this may not be possible due to too many opinions but maybe we can all come to an agreement for the most part. My goal is to stay under $600 in aftermarket parts. What I'm starting with is a predator 212 with exhaust and air filter. The plan: high revving hp. I don't have the drag...

I was wondering the gearing on the jack shaft and the clutch. It is a mid peg with the original kidney bean wheels and rear sprocket.

I need lower gearing...! I recently installed a Preditor 212 on an mmb80 which has a 70-72 rear sprocket with 13.5"(+/-) wheels... I was going to try a 10 or 11 tooth front sprocket/clutch but all I could find in 3/4" bore with a 35 pitch sprocket is a 12 tooth... My issue is (in a...

As the title states looking to putter along down the trails and bush roads so that is the main focus of my build. What I'm in need of is some assistance in determining final drive gearing to suit the need. What I have so far is a 5 hp Briggs, wheels 4.10/3.50-6 and would prefer to use #41...

I have the common problem of a stock baja that its not that fast. I only live in a half-acre(ish) property. And for that reason I don't care about take-off speed at all. Seeing how it takes me about 4 seconds to cross my yard... I wanted to get at least 40-50mph on the roads rather than the...

Hi I have built a minibike with a Honda 5.5hp degoverned and uprated to about 9hp. It has 16" wheels including tyres .It also has a jackshaft and I am a bit puzzled on what gearing to use. I am not looking for top speed or torque just something in the middle.

Ok here's the deal I'm 300 lbs got a box stock project engine a 10.5 tall tire I'm looking for something to drag with but to do a lil riding too what kind of clutch should I go with and what size gearing should I use thanks for the help
