Honda timing chain check


Tahj

Recommended Posts

I just added a 1999 Honda 300 Trx FW to my problems.

Indicator lights work, has spark, carb been cleaned, valves set. Cranks - no start. Is there any way to check the timing chain without pulling the valve cover and looking at the marks on the timing gear.

The timing chain is behind EVERYTHING in the right case.

Thank you Mark

I bought it not running, did set the valves and cleaned the carb - still not running.

I have a Yamaha 660 project that I did have to change the chain and cam timing gear along with a bunch of other stuff - it was no fun so I was wondering about the 300. The 300 timing chain looks worse to do.

Seems like I'm not the great mechanic I thought I was.
Rephilracing suggested that I do a compression check. It has no front deck and the gas tank was off, so I took the carb off the engine intake for the compression check

Compression was 150. I had cleaned the spark plug previously and neither time I took the plug out was it wet, couldn't smell fuel in the exhaust either.

I poured a little raw gas into the intake and it started right up. I ordered an Amazon carb to check my theory, then I'll go back and rebuild the original carb properly.

It's nice to know these run with old timing chains, they have a good reputation for toughness.

Once you get it running listen to the timing chain. If it's worn enough to chatter it needs replacing. One thing the 300 doesn't do for long is run with a toasted chain. It'll smack a valve into a piston like it owes it money. Replacing is extremely easy with the top end and side case off. Sounds like you about have it licked though.

So much for chinese carburetors. I swapped the carburetors - same stuff different day. I poked the cold weather primer and got fuel back into the airbox when I cranked it.

After long cranking it idled a bit,then quit. I stuffed a rag in the airbox carb inlet and it blew it back out.

I guess tomorrow I'll take the lid off and see. Not looking forward to going into the clutch case tho. Been busy looking at how to videos on YouTube.

D-Ray Smith has some good videos that don't give you motion sickness. Four Wheeler Doctor is good too. Hand held cell phones are the worst.

Just for fun the starter reduction gear that turns the motor over for timing check - the one that the allen socket is on - goes into the main case so I would have to split the cases to change the shaft to time the engine. Anyone want to buy a parts machine? 
It does have the WARN 242 front shaft on it.

How's your day going?

Original Warn 424 will bring about double original retail. If it's functional it'll bring $500 on the Honda 300 Facebook page. Wide open bought the patent and ceased production a few years ago. Rumor has it wide open will make another run but as of today, they're scarce and worth a fortune.

      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.

      Hey all!
      I'm on a mission to buy my first UTV soundbar as a gift for my dad(a newbie on ATV). I'm aiming for something that offers great sound quality without breaking the bank – my budget is around $250. Right now, I'm considering options like ecoxgear, kemimoto, and boss.
      Does anyone have experience with these brands or specific models that you'd recommend? Any advice or suggestions would be super appreciated!

      Hello, would this be a good Master Link tool for pressing master link plate back on? I've seen others made of aluminum but thought this one might hold up better. Thanks! 🙂

      Hello,
      I was able to repair most of the little problems on my 2006 BRUIN. I still have little things to do...
      I changed the Hazard light Switch because it was not locking when pushed and now it is not working at all. When I connect it (not sure of the wiring -4 wires but a lot of connection possible on this HELLA 3916-01 switch-) the flashing lights button (on the handlebar) is acting like the Hazard light switch.

      Hey all back again with my 1989 moto 4 250.
      After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!
