How far off can sprockets be

[insanecreations]

Putting a yz450 in a triz and I've got the sprockets within 1/2 in center to center is that enough cause the chain to jump off? Thank in advance.

How far out of alignment they can be, all depends on how far apart the sprockets are from one another. For the least amount of chain derailment issues though, they should be directly in line with one another.

I would not run a machine unless they are directly inline.

Aside from the sprocket issue, got any pics of this machine? I'd like to see it.

Thanx red rider guess ill jus have notch this frame out a Lil bit so the front of the motor can slide to the left.

1/2" is no good. With as short swingarm an 1/8" might be ok

I have one on my phone lemme see if I can upload it

says message is to short have to add this lol

Is the problem frame clearance or just sprocket alignment? If the issue is just alignment there are inexpensive options to move either sprocket in or out from the centerline of the chassis. As far as allowable offset 1/8” as mentioned is very unlikely to cause a problem. I’ve seen factory alignment out by more than 1/16” on some bikes (my dirt bike for one) and many bike riders have mixed up their rear wheel spacers and unintentionally misaligned their sprockets by 1/8” or more when they put the wheels back on.

The distance between the inside of the plates on your chain is at least 1/16”wider than your sprocket, so if you multiply that by 2 you get 1/8” to use without risking any side wear on the sprockets (imagine the chain is tight to the outside of the counter sprocket and tight to the inside of the rear sprocket, but the chain rollers are still squarely seated on the gears).

Once you go past that to say 3/16” or more you’ll see wear on one side of the counter sprocket and your chain will wear out a lot faster than normal. Considering how well a trike hooks up compared to a bike I’d guess it would wear out very quickly if you are out more than the 3/16".

I got it dead in line jus needed someone to tell me to go ahead an do it lol. I also have the front motor mounts nearly finished jus need to drill to more holes and then weld the bottom motor mount tabs on and she is in there.

A lot of the time, that's all a person needs. I learned a long time ago to try and do it right the first time around. It'll save you a lot of headaches later on down the road. Good luck with the rest of the project, and keep the progress pics coming.

Does anyone know what the difference in 85 and 86 tripples

[Dirtcrasher]

Those motors are chicken.

I just hand tighten the cam bearing upper caps. I can move the crank etc etc, without it being a huge problem. Then I'll time them and set the valve clearances.

I don't even put the chain on. If you understand why/what and when/where it should happen and how to set the valves your golden.

Once set, only then chain has to be at TDC "COMPRESSION STROKE".

Uhh dirt I think this is the wrong thread...

It happens

lmao DC you crack me up


and im interested in seeing this bike finished, i hope your taking lots of pictures along the way!
