saw some 19mm chinese mikuni clones for sale has anyone tried one of these on a 5hp flathead?

Ok guys so posted a bit back asking questions on my mild build that has now turned a bit more wild. So basically ive got a doodlebug frame with a 212 hemi. Ported head with all the valvetrain upgraded, decked, wiseco piston, arc rod and flywheel, mod2 cam, and all the carb goodies including a...

I'm finally starting work on my JC Penny ElTigre. I wanted one when I was a kid and never got one, so I picked one up last summer only 48 years later.:thumbsup: I remember that they had a Tecumseh engine so I installed a Tec HS50. No that the engine is installed, once I sat on the bike and...

:hammer: So, i just got a rolling frame from Gigantic Bad Dog as a Christmas present from my younger brother. Now, both of us are in our late 20's and 30's and haven't built a mini bike in 15-ish years, so we are a bit rusty. We have been told by BD that it is recommended that we use the...

Hey everyone, Just wanted some input or info on a better tire selection. The tire will be for rear wheel doodlebug . I am going to order a rib tire, because I have those in the past and had good experience with those. I will 90% of the time be riding on the road . I want to...

Building what I think is an MTS-50, it has 22-11-8 knobbys on the rear, my question is what works best on the front? a turf tire or a matching knobby only smaller? will a knobby on the front be too aggressive or bouncy? comments and ideas appreciated. Randi

hello, i have a motovox mbx 10 and im looking to get street tires for it. the knobby ones i have dont seem to do so well when leaning into a turn on the pavement. my current tire size is 145-70-6. ive looked online for some street tread ones but so far im not finding anything that i think...

Hi guys, I am building a bad dog gigantic tire mini bike with 22 tall x 11 wide tires. I see one member (Webdr) built the same bike & noticed he used a NR racing Honda GX 200 & it sounds like it ran great, so it got me thinking. You can search for webdrs post (since i can't post links...

I will be building a 5hp Flat head for my minibike. I just want a better than stock motor, not a race motor. I have done port/polish, and eyebrows. I see in the "Awesome guide to modding Briggs 5 hp flatheads" thread a 94ss cam is recommended, but i dont see them on ebay. Are there other cams...

Hi guys, I'm a new member and working on my first minibike. It's a 71-73 Black Widow from what you guys have told me. I have to replace the jackshaft assembly and there was nothing left of the stuff that was on the old jackshaft. As far as the internals go is it just 2 bearings and 4...

I took apart my Sears/Manco and found the neck bearings to be garden variety 1/2" X 1 3/8" flanged ball bearings. I want to put the right bearings with the right load ratings in there. Mcmaster doesn't specify thrust load on their flanged bearings. Can someone point me to the right...

MDB was nice enough to recommend the Dyno 107ss cam as a very good all around solution and I am leaning towards this in my current build. I just wanted to update what I am doing to the engine and see if he or anyone else thinks I should go higher lift.. Also, I picked up a head and would like...

which round slide carb size would fit a 5hp B&S flatty the best? 19, 20, or 22mm? I know that the 22mm fits a 6.5HP clone very well, so my guess would be the 19 or 20mm, but does anyone know for sure which of the three would work the best?

Starting a new thread here rather than hijack one.... I have been dumpster diving and brought home about 12 carbs. Of these I selected these particular carbs to keep ( and stripped the rest for jets and floats and shite )...

Now here's a topic that could keep you learning for the rest of your life. What do we, as a group. Know about the various camshafts on the market, that are best suited to the engines & type of usage that we commonly enjoy? We have our: 5HP B&S Flathead 5HP Tecumseh Flathead 6.5...
