BUT, something which is a little concerning is there is a little bit of play in the front sprocket now , like the original was a little bit thicker than the aftermarket one. should this be a concern?

I dont think so, I think the way its designed is that the chain "auto centers" the sprocket. So as you ride the sprocket kind of automatically finds its center.

Mine was the same way.

I could be wrong though, hopefully its all good!

we have changed two hawks. neither had any play in front countershaft sprockets, either before or after...sure they sold you the right sprocket?

Mine have the same play too, I was concerned at first but it's been good no problems.

I had read someplace that the original sprocket is 20mm wide and the jt sprocket is 18mm wide. There is some side to side play but watching some vids about sprocket replacing on honda 250's this seems to be pretty standard.. Just checking with you all.

I recently changed the sprocket on my Kawasaki KLR650 to a 17t that normally went on the KLX600 (I think)... but during my research I found dozens of people reporting 'Leaks from the Shaft' showing up after several thousand miles of use (3 or 4k), and it was only on the motorcycle that DID NOT 'measure and shim' the sprocket(s).

Come to find out the 17t sprocket is 3mm or so smaller (width), those who put a few shims on with the sprocket had NO leaks from the same area, one guy reported having over 40k miles with a shimmed 17t and no leaks.

Good news, if you get a leak from that shaft, the gasket/o-ring is cheap to replace (even on a Kawasaki)

Hey y'all I'm new here. I just bought a rps hawk enduro from killer motor sports I read on here about sprocket changes so I figured hell I'll go will a 35 tooth gained 5 to 8 mph took my tip off the exhaust and gained 4mph changed my spark plug to a NGK and gained 4mph when I got the bike it was rapped out at 45mph after my changes it goes 62mph on the flat guna change the carb and air filter. See if I can get up to 75mph

So why is the part # for the rear sprocket JTR269 and the front JTF259? I did find a JTF269...which is the right front sprocket?

JTF259 (the F is for front) is the correct countershaft sprocket, assuming you wish to retain the 428 chain pitch. I would.

JTR269 (the R is for rear) is the correct rear sprocket, assuming the bike has the standard Honda XL185 bolt pattern 428 sprocket.

There is no such sprocket as JTF269, according to http://www.jtsprockets.com/

Ok, thanks Weld. I thought I found a 269 front on Google but you just confirmed I ordered the right one.

[Weldangrind]

Happy to help.

anyone tried a 17/47 combo?


the TT comes with 17/50 stock and I've only really seen people with either 17/50 or 17/45 combinations.


its only 20$ so might have to try it.

I leave the garage at 3300 and can be 4700 with a whole lot of room to climb in 10 minutes.
