If you care about performance read this

Luke Stroehlein /

Hey guys, this book taught me so much about how our engines work and how to make them faster. It's available for free. It's super technical but reading it will make you a wizard. Enjoy! Two Stroke Tuner's Handbook

Re: If you care about performance read this

I offered the same when I joined a few years ago , as did others well before me . ;)

It is a bible , of sorts , no doubt .

Re: If you care about performance read this

seriously, someone should boil this down to 10 moped pages with pictures. one page per chapter.

Pretty much means nothing to making to air cooled Moped go 2x stock speeds only larger cc racing bikes, if you build a air cooled moped with more cc than stock cylinder but retaining the same stock size cylinder and head fins size anything like they say would seize a moped if using stock non retarding points ignition,

When I worked on 70s dirt and Enduro bikes Yep that was my Bible but making Moped‘s fast with stock ignition has been trial and error for the last 40 years for me for there was no publications to make 60mph mopeds reliable for every day use.

I agree that the cooling surface area can be a limiting factor, but it all depends on how far you want to go. The book has excellent information on porting and even a lot of information on expansion pipe design which could definitely help everyone from a weekend tuner to a hardcore modder.

Just blueprint everything naci bearings

Port maps are port maps domed stuff squish band pipe calculations carb with boost area airbox..

Its mopeds burn up 4 Or 5 you'll get it.

I like Graham Bell's book better. It's more detailed, and more relevant to 70's technology. You can adapt his teachings to a 50cc pretty easy. It helped me a lot with making expansion chambers.

Google it for a free download

blue printing means getting like 5 of every engine part and measuring them all to the exact right tolerance to one another. I highly doubt literally anyone has every done that with a moped motor.

Thanks for the links . :)

I have the Jennings 'version' .

I want the Bell book , too .

In case one of them has something the other doesn't . ;)

Re: If you care about performance read this

Here's a free download link for Bell's book :

I also added the link to the WIKI . ;)

I use factory specs and then use better than military spec +-.004 on all parts remachined but the major is balance and counterbalance . the crank full circle or overthrow or is it square or oversquare you just might want your clutch to be slightly out of balance to counter the oversquared overthrow cranks vibration.

My fastest bikes all were on the edge of destruction when I got top speeds of 45 50 on 26 26 gearing 1515 sha 8p homonet.

Best copy I know is on my end table. Hehehe

Re: If you care about performance read this

Glad you found the link. I tried to copy it a few times but it just kept downloading it.

It's better than Jennings 'cause he goes, "I heard this might work..." While Bell writes "this works and here's why, and how to do it..."

I almost forgot about bell's book. I knew there was another good tuning book but forgot the name. Just downloaded a copy. Thanks!
