Question Nirve Cannibal Chopper Build

So, Hey Guys.

I'm new to this forum, and I've recently started on my first motor bike build on a Nirve Cannibal Chopper/2 stroke 80cc motor. I'm not the most knowledgeable mechanic (or a mechanic at all, professionally) but I've already learned a lot from reading in multiple threads in the Stretch Cruiser & chopper section of this site.

So no that the bio is over. I started my build last weekend and I've already gotten a snag that I didn't foresee. The sprocket is too small for my rim base cylinder (not exact name I believe). but I've went ahead an ordered the Sprocket from manic mechanic that can fix that problem.

I foresee that Ill have to build a way to clear the chain of the tire. Thanks to this forum I saw a custom part that someone had produced for the motor mount. It sets the motor 3/8s of an inch offset so there is enough chain clearance. If anyone knows how I can obtain that piece or who I could contact to get such piece? as I do not have any tools to masterly cut any of the piece or mold or bend any steel.

finally, does anyone know of any extra alterations that I will eventually have to combat?

I'm excited to get my bike up and running. Its a beauty!

"Axle" is the word I was looking for!

Welcome to the forum. You've found the right place to get started. I'll have to warn you however that you have chosen a bike that will present you with a couple of challenges for your first effort. The 'Cannibal' and the now defunct 'Switchblade' are the same bike.

To get an idea of what you might encounter during your build you might find some help by reading through this thread > http://motorbicycling.com/showthread.php?t=35675
The front engine mount and engine offset to clear the wide rear tire are two of the issues you'll have.

There is also another one on a Switchblade build I did after this one. I'll post a link to that one later.

Good luck and keep us informed on your progress and don't hesitate to ask if we can offer any help along the way.

Tom

EDIT: Here's that other chopper build for you to look at > http://motorbicycling.com/showthread.php?t=44276

Thanks 2Door for the reply.

I have been following your build of course not live but did get a chance to ponder on those challenges before I even got to them. Kind of living vicariously through your previous builds.

I do have a question for you though. I don't have any way to cut metal or fabricate any of custom pieces off hand but I did buy a motor mount that I think may work for the purposes of offsetting the motor to the left. Found it on Ebay
( https://www.bing.com/images/search?q...6o0&ajaxhist=0 )

It was originally made for the scwinn chopper series that came out. Do you think this would work?

The mount you linked to might indeed work but will still require some fabrication to the front end to fit the Nirve frame. I found that a 9/16" offset to the left was what is needed to get chain clearance at the rear tire. The 3/8" you mentioned in the first post might not be enough to allow good chain alignment to the rear sprocket and clear the tire.

Let me know if I can offer any help or advice. Good luck. That frame makes a great riding and comfortable motorized bicycle. That is as long as the engine is running. If you have to pedal very far, it can be......interesting

www.ghettobike.com makes custom mounts for that frame.

Be careful about buying parts recommended by people who don't build or ride motorized bicycles but only sell and push products from people who sponsor their events.

James at Ghetto Bike makes the only custom mounting brackets
for that Nirve and they are really well made.

He even has a pic of the mounts on the website.

Ghetto Bike is not a sponsor of Socal Motor Bicycle Racing and has never
given me or the race anything so I have nothing to gain from sdevers buying
or not buying them. James is not a member here.

CulverCityClassic and have Ghetto Bike make
their in frame gas tanks for them and highly recommend the company.

It's a high quality product for a decent price that nobody else makes.

2Door, could you make and ship these for $125?

Everyone should know by now that james- ghettobike is a master builder not some backyard hack - if he will do it for you it could never be better.
