Rear Wheel distance

I swapped out the 49 tooth sprocket on my 02 KX125 for a 51 tooth. Now the wheel is much farther forward than it was. There are no contact issues, but I am wondering what ill effects having the rear wheel forward will have, and if I should get a new longer chain. Input appreciated, thanks

i think that haveing the wheel further forward reduces straight line stability,but increases cornering?

I have heard that also but i was wondering how far forward is too far.

It does, but not dramatically so within the confines of the chain adjusters. It will also make the bike slightly more wheelie-prone, but again, not by a significant degree. The bike will feel slightly different, but it won't feel like a different bike.

OK well I am going to take it to the track and see how it feels and if it dosent feel right Ill change the chain and move the wheel back some.

mine was further forward. the rear seemed a little stiff , even though i have the clickers almost all the way out. so when i got a new chain last week, i made it longer so i could move the wheel all the way back. there is a noticable difference in the rear, doesnt kick as much. but it still corners well. i need to get it revalved

      So i know my way around a crab pretty well and i'm very familiar with them i just can't seem to get the kawi dialed in it seems to have this unging/erratic rev thing going on when i pull in the clutch and i slow down so i'm looking for the correct carb adjustment for the bike it didn't seem to do it when it was warm out but now that it's in the 30's forties it's doing it my elevation here in upstate ny is 295' it's been around upper 30's lower 40's but i'd like to tune it so it's ready for summer because i don't ride it much in the cold so i'd like to tune it so it would be best in 70-90 degree weather since that's pretty common around here So could someone please help me out I need to know what the fuel to air mixture is needle position and proper jetting thank you

      so im rebuilding my bike again as you can see in the before and now pics, im a creature of habit and when i ride i mostly use the front brake because of years on a street bike, im thinking i want to tie the front and rear brake both to the front brake handle and still have the  separate rear pedal just like on my 2014 artic cat 4x4 atv, and if it is possible to do by stacking the banjo fittings or would i need a brake bias to make it work rite, if so any ideas on this ridiculous idea?
