Kimjon Just for a laugh I put this monster tacho on my trike that I'll be racing.

I made a 12v battery using 8x AA batteries in series hidden under the seat.

Re: Turning reeds around...is this a good idea?

I figured around 46cc. Everyone rounds off the cc numbers. Honda 750, 736cc, my CB1100F was 1050cc. I ordered a new 50cc cyld & head. Some how it was bored at the China factory to 40mm, they gave me the parts, I modified a 40mm Banshee Sho piston to fit. It was .028" above the top of the cyld so I had to mod the piston top to clear the cap. It has more compression than stock.

The C1 Bigbore with 39,5mm bore has 45cc.

Kimjon Thanks EPR, he said they were 39cc. Theres a couple motors in a box taken apart, I'll measure those up out of interest.

I did a bit of research last night on water cooled pocket bike motors transplanted onto gopeds. I found thus bad boy!

Attachment 148473
Attachment 148475

So that's going to be my inspiration going forward. A version of this, but with my own parts made to adapt it, as it will be done on a budget...unlike this one where he used top end parts purchased from stores.

Next (or more likely simultaneously) I'll start the water cooled drift trike build.

Kimjon Yes, replica. 2 are blata steel chassis replicas and the other is aluminum framed replica.

I got so much stuff off this guy. He was so generous. I haven't had a chance to unpack every box yet, but there are 3x complete bikes that shouldn't take much to get going again.

And enough parts to make a 4th...plus a brand new motor as well. Boxes of carburetors, manifolds, air filters etc...etc...

Got it all back home now. In the weekend I'll unpack it all and figure out what I've actually brought. Keen to learn more about it all and get stuck in.

Chrisi It is a C2, a Blata Replika with Aluframe, was only built a short time.

Re: Turning reeds around...is this a good idea?

#17 looks like a GRC GP, all alum frame, like my avatar bike, or 50cc Banshee Sho. Does it have a Blata W/C engine?

Kimjon No rest for the....

Here's the pocket bikes I just scored. Haven't had time to really go through it all, having just picked them up tonight. However I'm stoked!

They all work, and the guy really knows his stuff. He drained all the fluids out prior to storing them. He gave me some o-rings for the water pumps, saying these normally need replacement. And heaps more stuff.

Here's some photos off the auction site:

The bikes that go will be kept that way. The spare motors in the parts bin will go on my latest drift trike and a goped bigfoot that I'm currently working on.

Re: Turning reeds around...is this a good idea?

Well, looks like some ones been busy, the water cooled deal sound real good. I am still looking for a coil bracket and water pump pulley, hard to find now.

Kimjon Hi guys, been a while since I've checked in here. I've got a bit of reading to do in order to catch up...

I've made a few more things lately:

Attachment 148401

Attachment 148399

https://youtu.be/f3PRb3UgQtQ

And here it is on first start up with pipe on. Since this video I've upgraded the carburetor to a larger walbro.

Attachment 148397

https://youtu.be/YI55D4TAM8E

I finished Mitch's trike. Using industrial chain now, as opposed to the junk Chinese chain I'd been previously buying. So much better!

Attachment 148395

And just started this one. It's going to get a water cooled pocket bike motor on it. Should be a bit of fun once completed.

And the reason why I'm putting a pocket bike motor in it? Well I got lucky and brought 4 water cooled bikes for $100usd. Plus an extra motors, frames, forks, wheels etc etc...so much stuff. The guy raced 10 years ago...but gave up, and I got lucky.

Thanks, it's my second/third attempt at it.

V1.0 wasn't a bad idea...it just didn't work as well as I was hoping for. This one V1.1 is possibly still a little light on the spring tension, however it's working fantastic...So I'm going to not do my usual and "try fix something that's not broke". If it ever does let me down I'll just increase spring tension then.

Kimjon Today's efforts. I was never happy with the hairpin style spring on my chain tensioner. It was ok, but never great.

Attachment 147119

Attachment 147121

So I added an extension to it and converted it to use a couple coil springs to add the desired tension.

I've just put an entire tank of gas through it and haven't had any issues...I'll call that a success!

Kimjon Haven't been on here for a while.

I finished that goped. The combination of bigger carb, porting and pipe work well. I'm very happy with the results considering it really didn't cost anything to do.

Attachment 147093

This is my favourite view. Once you've put it together they all look the same😀

Then I made myself a drift trike. Started with a lifan 6.5hp and made a manifold, port matched everything (think you guys call that blueprinting?). Added a much bigger VM26 carburetor and did all the usual stuff like remove governor and oil cut out switches etc... anyway here it is all done:

Attachment 147095

And a quick video:

https://youtu.be/IuNrZGgkXVI

And then I've started a new one for a mate MITCH as the license plate says.

Attachment 147097

Waiting on delivery of a few small parts to finish this trike. That's 12 trikes now and a good enough excuse for another drift trike race. The smack talk has already begun and hopefully it's as much fun as the first time...

https://youtu.be/FRoEchndnRI

Now just gotta read all of your posts to catch up on what's been happening on here....

Nice work, looks like you got everything covered, go, go, go.

Kimjon Sorry I've been a bit distracted lately. I sold a heap of my stuff for a couple reasons:

1) free up some cash, in order to buy other cool things with. Hey it's my version of recycling...though I doubt the planet really benefits<img src="https://www.pocketbikeplanet.com/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

2) clear out my shed, so I can move on with completing it the way I've always envisaged. This has been stalled for about 5 years...now I can move forwards.

Oh, and I seriously had a crush on this LS1 ute...so I brought it<img src="https://www.pocketbikeplanet.com/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

Attachment 145773

It's a Holden Ute, which I don't think you guys in the USA get to enjoy. But pretty much like an El Camino...But in Australia they never stopped making them. It's got a 5.7L ls1 motor in it, and as you'd imagine, it weighs next to nothing...especially in the rear end! Think burnouts...Yes!!!!

-- ------ -- -----

Anyways, my goped project is also taking shape. I'll let the pictures do the talking:

Attachment 145779

Attachment 145775

Motor ported using techniques I learnt doing the cag motor. Plus using a few assumptions

Attachment 145777

That's it back from powder costing. I like the black, gold, green metallic mix they used. It really comes to life in the sun.

Attachment 145783

Attachment 145785

Attachment 145787

Exhaust mocked up. And overall I think it's coming together nicely for something that doesn't owe me much money.

Thanks EPR. I looked an OMB website last night. They make anything and everything you could ever dream of for these motors...but very expensive.

Then I thought about all the KT100 kart motors that owners are ditching for the rotax125 instead. These KT's are going cheap (about $150US) here in NZ. So I'm going to look into these. I may be able to make/adapt a rotax 125 centrifugal clutch and starter onto the KT? Something to look into anyway.
