Looking for more low end power

[DieselOutlaw]

I'm looking for more low end power the bike currently runs 80+ no problems but I don't ride more then 60 most days and was wanting to get some acceleration I was thinking bigger rear sprocket or smaller front sprocket is this correct? Will I need a new chain and to somehow adjust my spedo? Also when looking up how to adjust my chain tension some say to loosen the axle nut and some don't is it necessary?

So are you looking for more power or just a gear ratio change? What sprockets are you running now? If they are relatively new a chain may not be necessary. Also, if looking for more power, what mods have you already done to the bike?

[DieselOutlaw]

A gear change I know these bikes aren't known for big hp lol. Stock sm sprockets and 300 miles on the whole bike. I've got a 3x3 and muffler right now but my jet kit is on the table at home and my head pipe is in the mail.

Personally I wouldn't run the bike at all right now. You opened your intake and exhaust but didn't rejet, so you're running lean.
That aside, those mods, a well tuned carby, and a quick throttle will definitely feel stronger than stock. If you need more, a big bore and intake cam will help but sprockets are much cheaper

If you only have 300 miles on the bike then a sprocket change will not require a chain. Yeah, a tooth or 3 will make the bike feel a lot punchier.

The speedo is not adjustable. It is mechanically driven off the front tire, sprockets won't affect it.

The jets will pump up you're bottom end power

[DieselOutlaw]

Thanks which would you recommend down some teeth in the front or up some in the rear? The bike is running lean but I'm not riding it until the head pipe gets here and the jets get installed

[ohiodrz400sm]

Ride it with the jet kit 1st and see that you think. 1 tooth on the front is equal to 3 on the rear . If 60 is your max, a 14 front would not be that bad.

One down in the front is approximately 3 in the rear.  Front sprocket < $15 , rear sprocket $50 or more, if you want to save money change the front one and do the loctite fix at the same time.

Thanks y'all I'm def gonna ride it with the new parts first to see but I'm a torque junkie lol so I'm sure I'll end up with a tooth down in the front sooner or later

Smaller Counter shaft sprocket is Definitely advisable if that's what your after . Cons are more rub on the Chain guide .keep an eye out for that . If you go the route for a bigger rear sprocket your best bet is to get a chain sprocket combo . Reason being that with a bigger rear sprocket you may have very little if any clearance between the chain and chain guard in the rear .Having a longer chain will increase stability and any clearance issues .

One tooth down in the front is roughly equivalent to two teeth up in the back.  Down in front = lower gearing = more torque = quicker acceleration = less top speed.  Up in back = the same as down in front.  The size of the front sprocket is ultimately limited by the bend radius of the chain to 12 teeth or so.  Any lower gearing than that will require increasing the rear sprocket.

So the fix would be up two or 3 in the back and remove the chain slash gaurd?

You will have to keep an eye on chain guards and chain rub pads.  Going down in teeth on the front sprocket will not require a longer chain, in fact you will have to move the rear wheel back to tighten the chain back up to spec.  Going up in the back is almost certainly going to require a longer chain.

14/47 is very doable...............

LOL.. No!
 Do not remove the chain guard . If  you go the route of adding a tooth or two or three in the rear then you will need and want to replace the chain so you have more links in the chain moving the rear wheel further back and will have more then enough clearance with the chain guard.

Which is + what front and rear?

Gotcha for now I'll most likely just drop one tooth in the front and see what I think

For SM, stock is 15/41, so that would be -1/+6. Or a ratio change from 2.73 to 3.357.

For S, stock is 15/44, so that would be -1/+3. Or a ratio change from 2.93 to 3.357.

Thanks for explaining that. But that seems like a little much for me lol I think I'll just stick with the -1 up front when I do it

It is stock DRZE gearing.
