On TDC of Compression Stroke, using a feeler guage, tighting to .003" on both valves. And they are 18lb springs.

I thought I tried tightening lash but no effect, Will try again. And it is the old style predator- NON hemi. Valve springs are 26lbs If I remember right. That's gotta be what it is cuz those are the only things I took off.

And yes I am getting great spark. Can someone explain to me this compression relief on the cam? It sounds like thats stuck.

Hey guys bought a fresh predator motor and first thing I pulled the govenor and guts out, put an ARC Flywheel on, Higher tension Valve springs, and an air filter and jet kit. But I did not touch anything else. Now I went to break it in the other night and oiled it, and as soon as it hits...

Both actually. The one i have now is the actual Tiny tach, but still laggy. Its mostly the night riding

Hey guys wanted to know if snyone had any experience putting a tach meant for a 4 cyl on a small engine. I've tried tiny tachs but they lag and the no backlight makes it hard to ride at night. I was thinking of finding what rpm on the tack equates to its 1 cyl rpm, and putting a new guage face...

Sorry if this is in the wrong area I couldn't find how to post in a catagory. I was off school a long time ago, and im on my phone in between periods and on my bus ride to tech school.

I think its the bronze bushing. It looks alot smaller then I remember. I think it slid under something.

Or it sheared off more than half of it in 10 mins...

Nope I found it. The brass bushing somehow got shoved into the flat pully on the crank close to the block

At school now when i get home I will.

Found this so something is wrong.

Its like brand new though which is weird. Its s custom build too, and my chain is pretty tight, could that be a cause for failure?

Is the driver clutch supposed to slide though?

Its not the bolt, and it doesn't rotate free, but I have a feeling that something is missing. You know the little extension peice? I think that may have broken.

Hey everyone I recently bought a knockoff comet TAV. After riding it the first time I noticed the driver clutch is very loose. It moves in and out relitive to the crankcase. When I installed it it never slid. What happened? Its not spinning free or anything but i belive the sliding is causing...

Ok so I am building a HF predator 212cc motor with no govenor, and mostly billet parts. I broke the first cast connecting rod due to over revving. I saw online a Digital hour meter/tach with a "Max RPM Recall"... What is that? Is it a rev limiter killswitch? Or does it tell me im over and is it...

Ok everyone I am making another custom minibike. Welding a frame, fabricating parts, you know. Anyways I am planning on putting on lights and a horn, and want to get it registered. However, I can't just keep changing out batterys and I want to be able to drive without fear of dying. So my...

This isn't a homemade bike, I actually MAKE my minibikes, everything from Welding the frame to creating a sprocket adapter. I'm sorry but I work hard so I may call my bikes "HomeMade" and when someone buys a bike, adds somthing, and calls it "HomeMade" It really annoys me. I'm 15, and been...
