High Performance Wally World Cruiser?

You master of suspense! You know we do! Say, whats the diameter of the seatpost hole on that cruiser? and is it a steel frame?

Wow! You are going in depth, aren't you?

I can't make any reasonable comments on the engine work, in fact. Because I've never gone into them that deeply.

But I have had a motorized Cranbrook. And it was a good frame for the job. But I'll bet you already know that since it looks like you've already got a few miles on it. And, yes, it's steel and the seatpost is 1 inch, or 25.4 mm.

Nice looking stack of stuff there YILDS,

If your results are the same as mine the only thing I see in the stack of stuff that wont add any performance gains is the CDI kit, my personal testing on two different bikes and two different engine set ups showed no improvements over what the stock kit CDI delivered, but I do like that it has a good coil and I like the key switch, it does a good job and allows the engine to rev just as good as the stock unit unlike the Rocket CDI I bought or the older style jaguar CDI which decreased my top speed by a few MPH when I used either of those units compared to the stock unit or the Lightening CDI.

The Lightening is a well made unit and it does work good, and who knows maybe your results will be different than mine, I just didn't see any performance gains with top speed testing or testing on hills to see if my mph would be better or worse when pulling hills and such.

As far as the bike your using, I like the Huffy Bikes myself, I have one that I put together back in 2010, it probably has about 1000 miles on it now and hasn't given me any trouble, the coaster hub they use on these bikes isn't as good as a good Shimano hub but mine has held up just fine so far.

I think you're gonna have a real nice build when you get done, if you do the right things to the engine you should have a 40+mph bike that should cruise nicely in the upper 30's-40's mph.

Best wishes with the new build, hope it does just what you want it to do and proves to be as reliable as a china girl engine can be.

I like the snake pipe... Where did you get it? do you have a link?

Thanks guys and Map I mostly bought the Lightning to see if it would give any gains. I'm going to have a testing between the stock CDI and the Lightning and film the differences with my go pro and use my phone as a speedometer. Need to figure out a set-up first. NEED to get everything put together first!

Items that might be considered further down the build is a bigger carb and reed valves, but we will see where we get with this first as there is something as TOO fast and this already over that I believe. My junker PK80 hits 40-45 easy and that's too much, but why not try for 50!?

I understand completely, that is the same reason i got my lightening CDi, just wanted to see if it lived up to the hype and if I could actually see any performance gains on any of my bikes compared to the stock unit, I have stated my results but I wont say someone else wont see something different.

My fastest bike would run 50.3 mph according to my GPS with the Lightening unit and the same bike actually registered 52.0 mph with my stock unit on the same day and on the exact stretch of road.

Your results may be different than mine and if so that is great.

I have found that some things claimed to help performance actually do help and some things that are claimed to help performance didn't do a thing for my engines and in some cases actually decreased performance.

Some of the stuff is just trial and error until we find what we think works best for us and then we stick with that, part of the fun of all of it is trying new things and experimenting to see what we like best and what we can tailor to our likes and needs for the type riding we do, since I ride open road a lot for longer distances rather than just hopping around in town from block to block, like my bikes to have better performance at faster cruise speeds and since I live in an area that doesnt have huge long hills I can gear my bikes for the way I like to ride without many issues.

I dont really need expansion pipe exhaust for low to mid range power boost, I just need something that will flow good so I can reach the rpm's I need for the best cruise speeds on the long stretches of road I like to ride.

If I were just zipping around inside town a lot with a lot of stop and go riding id have my bikes set up different and probably run abot a 40T on the rear and try to get my exhaust tuned for good low to mid power and I'd shoot for a top speed of about 35 mph that I could get to as quickly as possible, my bikes aren't ideal for a lot of in town riding since they have small rear sprocket and are better suited for long stretches of 40+ mph cruising.

you'll have a good set up when you get done sounds like, I do think you will nee to modify the "snake pipe" exit diameter to get the flow for ever seeing a 50 mph top speed, but I could be wrong and you may get it done without needing to increase flow capability, my 45mph bike would not do more than 37mph on the flat with that chamber and a 3/4" ID header pipe, I think the header pipe on mine being only 3/4" was my biggest problem and that will get changed eventually and I'll try it again.

Also for a lot of these items I will be making youtube videos for benefits and performance differences between stock and the chosen item etc etc.

You show that you are gonna be using a good Japanese mad upper bearing, just curious about where you got the bearing and is it 15mm in width?

whats next? lots of little jobs....

for the exhaust layout? did you have something in mind? i was thinking or picturing rather- along the frame down tube / outlet under the crank. and a knee guard of course.
but any way/ anything will be great im sure. i have a cranbrook needing a pipe so i will stay posted.

Pretty sure I talked to you about the bearing in the past before this recent build. It's KT101415 Needle Roller Bearing ID 10 x OD 14 x L 15mm IKO from bearings direct. Been running it in my current engine with no problems.

Yes that's where I have got some of mine also, never had any issues with them.

I've also ordered these form the UK, they are IKO Bearings and are cheaper than getting them here in the states which is just crazy in my opinion.

http://simplybearings.co.uk/shop/p9...e+Roller+Bearing+10x14x15mm/product_info.html

Bearings Direct is $8.50 each plus shipping, in the UK is just E3.35 = $5.06 US shipped from there to the US, I just ordered three more a few minutes ago for $25.29 total cost and shipping is E6.23 = $9.42

Makes no since to me that they will ship cheaper from there to here then what it cost to have things shipped a few hundred miles from here...LOL!

Anyway just thought I would share this here if you don't mind YILDS for another source for the good quality bearings.
