I want to put -1 on the front sprocket. Hopefully this means i won't have to adjust the chain. Also will it affect the speedo? bike is a ZX6R J2 (2001) Also what will the difference in acceleration be like. Bike is 33bhp restricted. Thanks. Thumbs Up

If you don't want to adjust the chain I'd go up 1 at the back too.

It will affect acceleration, but I'm not sure you'd really notice on a 33bhp bike.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

speedo will be out by 1/16th of a mph but there will be the regular 10% out on top at speeds over about 80mph fitting +1 at the back will keep the chain at the correct lenght but the speedo will then be about 1/24th out on top of the corrected readout plus the regular 10% out on top of that Thinking

I think this is how it works but don't quote me Wink

acceleration wise it is the best option for a 33 HP bike other than an atkins diet Laughing

after all you can't exactly have more power yet hey?

dropping a tooth on the front will make a clear difference to the accelleration on your bike especially due to it being strangled down to 33hp

I thought -1 on the front i would be able to just move the back wheel abit to tighten the chain. I am getting the impression that some people think it is a good idea and some not, being 33bhp. So confused.

When's your restriction up mate? I'd say it'd deffinately increase acceleration, and I'd recon you'd notice it. I changed from 15t front to 14t and I really do notice it.

Got another year after the 12th May. Confused

I don't want to take the restrictors out because my dad will kill me and it would be just my luck to fuck up if i did.

So you think it's a good idea then. The sprockets are only like £20 so won't loose much if everything goes bad.
