I am going to order a couple jets for my bike, I ordered ones for motorised bikes but they are m4 not m5 thread, and I can't find any m5 ones specifically for motorised bikes, so I was wondering if m5 jets for a dellorto or mikuni will fit? The engine is just a cheap chinese 80cc with the stock...

Howdy, 1st post and happy to finally join! Wasn't sure where to post this, as I'm new, but here we go. I've been interested in making a fresh hill climber for hiking/mountain bike/dirt bike trails. I am chill as a cucumber if I can't go faster than 25mph max speed, as I know with these...

So I planned on whacking a 2 stroke engine kit from eBay onto a push bike and couldnt find any decent hybrid bikes in my area. I walked into a well known local bike shop and fell in love with one recommended by the owner - A Python Quantom 8000 Men's hybrid bike. I fell in love and purchased on...

So I have set the engine onto the mountain bike have checked the spark plug for spark and I do get spark when tested on the outside case. I can get the engine started when I peddle to 20km/h but it wont idle and The throttle needs to be full throttle. If I start at a lower speed I get...

Lots of work into this build for shiny side up 2017 and is a late post but I finally got some time to put it up here. As for the build : I custom made the fat tire bike frame from customizing a mongoose fat tire bike. I customized a girvin linkage fork by widening it out to fit 4" rim and had to...

Took me a while to be happy with it but here it is the bike I built from the things I learned off this forum. It's the cheapest build but the best ride I've got. I was upset that I was done and all I could do is maintenance so I ordered the triple 40 zeda to work on through the fall.

I add front shocks on my bike that didn't have them to begin with...I had to jump through a few hoops to get them on proper but nevertheless they were installed shop quality. just to look at the bike I new the whole geometry was out of wack...the center line from front axle to bottom bracket...

I have an 80cc engine on my bike. Well about a week ago I was on a beautiful ride. I came up to a park that only had one path and got behind a maintenance golf cart. He was putting along pretty slow. So I cut through the grass and beat him around the corner. I rode out of the park and made it to...

I am pretty set on getting a motorized bicycle and would like to know y'all's opinion on bikes and kits. I was considering the 26" Roadmaster Granite Peak and the IGlobalBuy 80CC kit. My budget is a preferred $200 but I could do $250 if I should because $200 will get me crap. This is my first...

Although I'm not the greatest with repairing engines yet, I do know how to build a normal bike from the frame up and diagnose and fix pretty much anything that might be wrong with any part of your bicycle which was there before you put the motor on it. So I thought I'd let people pick my brain...

I saw this post where a guy just briefly mentioned about how a guy made panels to go on the side of his bike frame to cover the engine and everything to make it look neater... I am not going to quote it or give you a link because he just said what it typed above. But, how do I do this? I haven't...

I am thinking about getting a larger fuel tank, which will help me not worry as much when going long distances, and I won't have to fill up as often, but I am currently getting about 25 miles per fuel tank (I believe I have a 1.5 liter fuel tank on my bike). So, I was wondering, are there any...
