What's up guys, first actual mini-bike. My bike is about a week old and of course I'm increasing speed one small easy step at a time. Currently set up as 5" sawtooth tires fr/r. 12t front, 60t rear. Completely stock engine, zip tie on gov to get a few more rpms. So far I have GPS'd the bike...

Just bought a Z4M flat top to go in my gx160 but trying to decide which billet rod to use. .010 over or .020 over or stock on the rod length ? Haven't put piston in yet with stock rod to see how deep in hole it is but was wondering if anyone else has already tried this and can add some light as...

Hey guys, I am needing some help on exhaust pipes. I have been working on my DB 30 trike build for my wife and need an exhaust. My wife wanted the stock muffler because it is quiet. I made a custom TC mounting plate to house my 7" driven and I don't have a lot of clearance from exhaust to...

Here are some pics of my Stock Track 2 :

On some the later 3.5hp style engines they have a flange convertor that screws into the 1/2 pipe thead on the exhaust and sticks out just a touch with a standard 2 bolt flange for bolting on the bigger muffs that cant unscrew with the tank on. Anyone have a part number for that or a stock...

I picked this up at a swap meet for $100 minus chain a few weeks ago. I have looked it up online and found this site. (I am 16 and live in Washington state.) It was green stock. Someone put a 6.5 honda clone on it, and it looks like it had a 2.8hp on it stock. I am looking for a brake upgrade...

Anybody know how much rider weight a stock Manco Thunderbird will hold. I'm rebuilding it for my son but I would like to "test drive" it once in a while. I weigh 260lbs though. Thanks.

Starts right up, runs good, swapped on newer tires and wheels. Was going to do the Predator engine swap thing with it but my son has others. It's all stock the way it came with the 97cc engine. One other complete stock 97cc engine & Clutch goes with it or will separate. Things wrong: front...

I have the 212cc predator clone and recently installed the OldMiniBikes stage 4 hemi on my DB30, the kit doesn't come with upgraded valve springs. It has the mod 2 cam and I can't find any 22 lb springs to turn 7,000 rpms. It is floating the stock valves. Can someone point me in the right direction on...

hello everyone, I was wondering if anybody had any flow charts for a Honda gx160 cylinder head? either home ported or stock. I couldn't find anything, I need this for a cam grind reference

I recently installed OldMiniBikes's 8 inch header and angled air filter on my GX160, I already have a 140 emulsion tube and a .36 jet installed and the motor runs fine but the spark plug is really black and I am assuming it is running rich, this was both tested on a NGK BRP6ES and an Autolite AR3910X...

Hey all, I am restoring a 1974 5hp engine. The engine has not had very much use in its life, as there are faint remains of hone lines on the bore :laugh: I am doing this motor in its original white colours. I also plan to be using the stock flywheel. Which brings me to my point. I was...

Anyone seem the NGK hot racing coil selling on eBay for gx200 / clones ? Anybody bought one yet and is it a performance coil and if so how well does perform compared to a stock coil. Anyway to increase spark output of a stock coil ?

I have lurked for awhile and joined last night. I have an old bike that was my dads when he was a kid, has served as a pit bike at the drag and boat races. Currently had a briggs 3 hp , polished block, milled head and down draft carb. It has seen many changes over the years. I want to build a...

I have the ability to flow heads and carbs now, with actual CFM numbers. What are some of the highest numbers you guys have seen with modified heads? I am flowing at 28inches, by the way. I found some stock flow numbers on here the other day, and my stock numbers were right with them.
