I think I had a 13 tooth on the engine (way too big, but smallest I could find that fit at the time) and I was just using the biggest gear on the bike, which was like 36 tooth? I think

Must run in a 4 year cycle! http://www.spudfiles.com/forums/help-with-my-chainsaw-bike-t11395.html Ever wonder why these projects never seem to get finished or even some pictures posted with success? I actually did finish it, and it worked. Problem was I didn't really think about the proper gear ra...

Yeah that would probably work too.

Try saran wrap that might work.

Yeah seriously whenever I say that I could do way worse things and atleast I'm being creative and using my head my mom is always like ok I guess you're right. Tell us what they say once you try it.

my dad has one so im lucky enough not to need one. though if youre just using brass cant you just use a soldering iron. You can only use soldering irons for like connecting wires. You can use a blow torch and soldering for copper, but I don't know about brass. If he wants a MIG welder I assume he p...

I was also trying to get one for christmas. Same deal parents didn't want me to get one, although I kinda just gave up. I really wish I could weld there's so much more I could make. Just tell them that you could be doing way worse things, ask them if they would rather you ask for a bong.

That is almost the whole point. Building something is like a huge puzzle you have to overcome things to get there. I have plenty of projects sitting around that I haven't finished and I started them a year ago. I have a propane injected gun with 120 bucks into it that I haven't felt like working on....

Yeah you are right that was the calculation I did with a 13 drive sprocket and a 22 tooth sprocket on the jackshaft. I will be able to tension them and they are all out of the way from anything since they are above the rear tire. But the drive sprocket will have a chain gaurd and I'm sure I'll fabri...

I'm using two jackshafts with gears in order starting with drive and ending with the rear of: 13, 20, 8, 20, 8, 36 for a total gear ratio of 19:1 :P . Now I have 2.76:1 so huge difference. With that set up I won't burn out my clutch I will have lots of torque and go around 40mph! I'll post the resul...

Yeah I know that's what I'm going to do. Try and get like a jackshaft with like a 10 tooth sprocket and a 30tooth or the biggest difference I can find.

The engine is 42ccs and I'm gonna use a jackshaft to hopefully get a gear ratio of atleast 14:1 right now I have 2.75:1 lol.

Well that's what is happening now because I had to ram the clutch drum into there so hard that the bearing won't allow the drum to not spin. But still without the clutch I don't have the correct gearing. So I am just going to bite the bullet and buy a jackshaft and some new sprockets if anyone can h...

Ok I'm just gonna suck it up and change the gear ratio. I'll buy a jackshaft on ebay and mount it under the engine and I'll have to move the wheel so the sprockets are on the other side. If I'm using a jackshaft what are two size sprockets I want to use to get my gear ratio to 14:1 is that even poss...

I want to not have to pedal at all. And go fast Update: Well I tried out riding it today and it worked but I only went about 10mph (just on idling speed) and nothing really happened when I gave it some gas but I didn't want to rev it too much. And then after about 10 minutes of riding the clutch sta...
