Does anyone know what to do with the port on the stock air filter assembly on the predator 212? I replaced the gas tank with one that doesn’t have the breather hose the old one had so now there’s an open port on the air filter box. should i just plug it or leave it be?

This started happening randomly, initially it would kickback 2-4 times before it would eventually turn over and start running, but it ran rough and hot, and started dieseling when shut down However, after giving it a shim head gasket to bump up compression (because I planned on running it on...

Just got this cool minibike. It was hard to find much info and impossible to find parts. It looks like it’s called scooter_nuke, minimizer, mini bike x-power, or xcooter. I am hoping someone has a lead on the missing jack shaft. It’s kind of a weird one but I am an amateur. I could just modify...

Ok so I picked this up and prolly way over paid. But I have been wanting one for ever and I’m debating on a full restoration. Or just spray paint it and restomod it. The number on the back drop out is hard to make out they put the paint on thick on this one, as in the last owner but I think it...

I have a predator 212 hemi and just got the mikuni GPS clone from go power sports with a 16 pilot jet and a 130 main I've swapped the 130 main to a 115 now when I start the bike it idles fine doesn't creep forward at all even when I'm not sitting on it but when I pick up the back tire off the...

Hello Everyone. I bought this old bike a few months ago, I haven't been able to ride it a whole lot. The problem I am having is that the chain keeps coming off the rear sprocket. Nothing I do seems to rectify this issue. I started with replacing the chain, since the other one broke. This did not...

Hello, I’m building a predator 212 non hemi and need advice on achieving a 10.5 to 1 compression ratio, how much should I shave the head? I haven’t measured how deep the piston is in the hole yet because I already took the whole engine apart and I’m waiting on my ring compressor and other parts...

Good afternoon, Just reaching out for some help for some probably self-inflicted problems. I have a stock predator 212 bike and stupidly leaned it against something unstable. It fell completely over on the air filter side and was there for probably 30 minutes and a ton of oil ran out the carb...

Hello everyone. I just got this 6.5hp vanguard for a good deal on fb marketplace. I cannot get it to run without spraying starter fluid into the intake. Once I do that, it fires right up, and stays running.

Hello everyone. I have this vintage Briggs and Stratton 3hp engine that I am restoring. I replaced the old breaker points ignition coil, to the modern electronic magneto coil. After I did that, it started right up and ran perfectly. From there, I removed the carb and gas tank, so I could repaint...

Hey everyone, I have been restoring this old Briggs engine for a mini bike project. Before I took it apart to paint it, I replaced the magneto coil, and it fire right up. Once I finished the paint and reassembled it, I tried to start it, and it would not go. I sprayed starter fluid into the...

Hey guys, I recently rebuilt my Hisun 196cc motor and when I run the engine it idles roughly. Here's some specs 18 LB valve springs PVL Aluminum flywheel with 31 degrees BTDC Billet con rod governor removal BSP-2 cam Everything else stock The engine seems to run fine at higher RPM but at idle...

Hey guys, so this is my first time posting on here. I'm currently rebuilding my Hisun motor from my Coleman CT200 and I was wondering if I should get rid of the plastic camshaft gear soon. It just seems very sketchy to me to have a plastic camshaft on the motor. Here's a list of mods I have...

I've read a few post and searched threads and need to install a pulse line for my fuel pump. Wondering where y'all would drill and tap? Tecumseh uses vacume fuel pump I believe, I also have no experience in this and am learning as I go. Whoo hoo! The tube coming out of the cover below the...

There's a listing on craigslist listing for a 5hp briggs and stratton and it looks decent the guy said $60 and its mine it starts on starter fluid he said but then dies so its probably a carb issue. Is this a good price and will it be a cheap fix?

So i’ve thrown together a pretty strange setup for my chain tensioner on my minibike. The issue i’m running into however is that the chain is completely destroying the roller wheel. I’ve had on wheel get completely eaten all the way to the bearing and now caused a chain to break. My question is...
