it's always recommended to change the pair at the same time... that's the conventional wisdom. that said, if the front sprocket is in good shape and showing no sign of wear you could just do the rear. considerations are things like, how much is the new front sprocket... if it's $15 and you're not sure if it's in fine shape then it might be a good investment to go along with your $100 chain and $80 rear (i'm making up prices to illustrate the point) or if your rear is showing slight wear but it's aluminum and your front sprocket is steel, then again, you might just get the rear. unless the front is reeeeeally pooched the only real issue is how much faster you'll wear out the other components. you pay now or you pay later! you can only defer maintenance, you can never avoid it!
that's a massive jump in tooth count. What the heck would you large for? If you don't raise the tooth count up front you'll end up with a quick blast 0-30mph or so then nothing......
Again...why such a massive difference?
Guessing that the (honda) gearbox sprocket is around 16 teeth, the 36T rear sprocket gives a 2.25:1 ratio. The 45T rear gives a 2.81:1 ratio, or about 20% different. That means that your rear wheel will go around 20% slower with the 45T rear sprocket. So, first gear will become irrelevant, and top gear will be winding out 20% sooner (at somewhere around 70 mph). Good scrambles set up.
I'm guessing that the KZ400 comes with a much larger gearbox sprocket.
Hey all, new here. Just got myself a 72’ Honda CB100 with a CL100 engine swap. Im replacing the lighting and fenders, but I’m running into an issue with finding compatible lights. Everything that I’ve found that is low profile runs on 12v, but the bikes battery is only 6v. Haven’t done a TON of...
Hello all............recently put a new battery in my 69 cb175. Battery died after a week or so. I only rode it for a total of an hour within that time. It usually takes 6 cranks with starter to get her going so i imagine that's draining the battery significantly. I also have an H4 type bulb...
Is anyone running an older DR650 as a stripped down trail bike or desert sled?
I am currently working on one, and trying to find a good exhaust, tire and seat setup. Open to input and suggestions.
In general, will mounting tires sized (110/90 -18F) and (120/90 – 18R) make a difference one way or another if a bike has tire/rim sizes to accept (100/90 -18 F) and (110/90 – 18 R) stock by the manufacturer? No clearance issues being a prerequisite.
Working on a bike that has a sorted history. Don't know any more about the motor other than it is a '83 or '84 CB or CM 450. Trying to figure out if we need a CDI when rewiring with a Motogadget M Unit?
Would appreciate help as we try to determine a wiring diagram.
