Ok, I will check it out. over the weekend, I pulled the carb off to check the float, I swapped the float out for one out of the other Chappy. I also noticed that there was what seemed like two jets in one part? there is a main jet (the bigger one right?) and then another right by it. It is smaller, I was able to remove it to clean it but on the other carb from the non running chappy, there was a jet that screwed way down in there, then another that stuck out about 1/8 of an inch .... I wish I would have taken a picture! what is this jet?

the carb needle.. where is that in the carb? are you talking like the jet? I removed the oil tank and plugged the inlet tube from the pump so that there is still oil in the pump, but nowhere for it to go. (so it doesn't burn out or something) I am now mixing my gas at a ratio of 40:1 I am at practically sea-level, what size jets should I go with?

legit my friend! thank you

how do I know what level my float should be at? you are a crazy bastard! too bad it didn't make that trip!

I installed a 25T rear sprocket and I can go 40MPH no problem now! its perfect, however when nearing the top RPM, it cuts out like it has lost all fuel. Then will recover if put choke on. Its odd. When I stopped the other day, I noticed it was leaking gas, everywhere.. I took apart the carburetor and everything was working fine (so I could see) but I think the float is not shutting off the fuel some times, and possibly shutting it off when it needs to be on, (at high RPMs) I sprayed carb cleaner in there to clean it really well but no luck.. what do I do? as for the non-runner, the cap on the side has been off for a few years and the stator is all rusty, *see pic* I would assume that once its cleaned off it should spark, I bought new points for her just in case. here is how the bike sits currently

7 mph would be great! 35 just limits my street use (: I ordered a 25T one online, they also sell larger front sprockets, but I will try this one out first! On another note, I have another Chappy with that 4 speed manual.. I cant get her to start though, any way to swap trans?? or better just have it rebuilt... cheers!

it revvs out quickly! has tons of power, that's why I am stuck at the 35 mph thing also. I understand the more powerful engine portion and I appreciate the patience you all have with me haha! I wish I could put a Tachometer on her to see what the RPM's are at full throttle. Its the automatic 2 speed (2 speeds in Drive, 2 in Low Range) if this helps at all. I found a rear sprocket that is a 25T compared to what I have now, a 30T rear sprocket.

lol I wont take it as that, but I don't care about the MPG, I want to go faster. So I was thinking of changing the gearing to go faster. and it sounds like I should only change the rear sprocket, not the front I don't want to dremel anything I don't have too!!

Got my LB80 going, has a small petcock leak at the moment, going to remove it and get a simple on and off one. anyways, my max speed is 35mph, I plan to change the gearing (sprockets) but need to know if anyone has done this route before, I want to get a bigger sprocket in front and smaller one in the rear. What size can I fit in the case without using the dremel? cheers! also, what is the stock gearing of the LB80? I read somewhere it was 14 front 32 rear..

alright, ill get one of those, replace the points and try to find the wire that connects to the coil.

I am totally new to this, what does "BTDC" I assume its something to do with top dead center? I have new points for it, I don't know where they are or how to install them. I took out the ignition coil and got a new one but forgot to mark what wire feeds the coil..

Hey everyone, I finally found a forum for the Chappy! I have two 1975 Chappys. One was my first motorcycle that my pop got me when I was 10. (the yellow one) I am restoring it to give to him for his birthday this year without him knowing. The engine is good but the other components are not so good.. (the red one) I purchased another 1975 LB80 locally and it has a bad engine, but good other components. So I say my yellow one has a good engine, as in it started and ran a year ago around December. I have it now in my garage and it is not getting any spark.. Where do I start?
