    Issue with hemi predator 212 after new parts

    Yep, literally quad checked valve lash since that kept coming up as the obvious solution to my problem, I've got it set to a tight .003 gap now on both exhaust and intake. If only I'd seen that sticker on the side of the gas tank about oil level earlier I'd have avoided all this headache

    Issue with hemi predator 212 after new parts

    Well, for future reference, after knocking out the most probable suspects (valve lash, coil gap) I ended up draining a bit of the oil to help with compression since I had it filled to the max line, I'm guessing it wasn't so much a problem with the stock springs (even though now that I think...

    Issue with hemi predator 212 after new parts

    I haven't messed with the governor, the spring right under The gas tank is moved into one of the holes which lets it rev higher and it was already in that hole right out of the box. I'll be taking it apart and double check valve lash, coil gap, etc today, what should I look for in terms of...

    Issue with hemi predator 212 after new parts

    I'm thinking I might have figured out my backfire issue, a week or two ago when I was mocking up the engine to the frame before painting the engine tipped and fuel poured out of what I'm now thinking was the carb, which might explain the fuel vapor hellion mentioned and would make sense, I'll...

    Issue with hemi predator 212 after new parts

    This is basically how it was put together when I started it, it looked like smoke puffed out of the filter, I did turn the idle control screw a bit to the right because I had it idling as low as possible before

    Issue with hemi predator 212 after new parts

    The governor is still in, I've got the governor springs set for the 4.9k rpm I've seen people get it up to, I'll most likely do the con rod when spring comes around. Would the valves be the issue? Do I have to set the valve lash to something even though the hemis should already be set...

    Wanna hit 40-45 mph on predator 212

    The valves seem easy enough to replace, is the billet connecting rod an absolute must if I get 18 lb valve springs?

    Wanna hit 40-45 mph on predator 212

    I'm not too worried about climbing ability since it'll only be for putting around the neighborhood/ whenever I go camping, also figured the clutch would help with increasing low end torque. I'm not so mechanically inclined that i wanna get into pulling the motor apart to change things like...

    Wanna hit 40-45 mph on predator 212

    What would be the smallest sprocket I could go? I'm trying to not remove the governor altogether, but I am planning on relocating the spring to max it out art 5000-5200 rpms

    Wanna hit 40-45 mph on predator 212

    Like the title states these are my hopes Parts list - 6" wheels - ARC billet flywheel with key with 8° advanced timing - max torque ss clutch 12 tooth - 72 tooth sprocket (should I find smaller and less teeth sprocket considering I have the max torque, or does the billet flywheel compensate...

    New mini bike builder, have questions/ concerns

    Thanks for the response Can't seem to find any aftermarket tanks that holds as much as the factory tank, I'm thinking of relocating the predator tank up top on the frame, any problems with this idea? What else would I need to buy to make it work?

    New mini bike builder, have questions/ concerns

    Also, my predator 212 motor does not fit in the frame, even if i lower the motor mount plates to being flush to the frame I still don't think it would fit. I have an aftermarket exhaust and intake coming in so those won't be a problem for clearance, the only problem is the gas tank. Before I...

    New mini bike builder, have questions/ concerns

    1) the holes I have in the frame where the ales should go do not match each other, the holes in the fork are a good size for a 5/8" bolt, but the back ones are bigger than even a 3/4", there would be about 2mm play. What should I do? I ordered wheels with 5/8 ID bearings and was thinking of...
