Just thought I'd let the other 250L owners know

Recommended Posts

I changed my rear sprocket from a stock 40 to a 48 tooth, it made an amazing difference. :confused:

I primarily use the bike for off road, but it didn't really hurt my on road speed much. It's possible to start off in 2nd gear with very little slipping of the clutch. Front tire comes off the ground very easy now. :excuseme:

I'm still working on modifying the rear chain guide, but it looks very simple.

I wish I would've done this a long time ago.

What size are you at in the front, stock 13? I'm running a 12/44 for offroad which would be very similar to the 13/48 you may have. Even with the 44 I still had to modify (file a groove) my chain guide. But yes the bike is much easier to ride on trials. Just point and twist, no worry about stalling out.

Still running the 13 in front. I figured if I wasn't happy with the 48 rear, I could switch to a 12 front later.

My 44 T is a Sprocket Specialists purchased through gnarly parts (I think they are gone).

They are priced around 50 bucks for an aluminum one.

I had to file a slot in the plastic spacer that goes between the two halves of the chain guide on the under side of the swing arm.

I ordered my 48t directly from Sprocket Specialists. Shipping was very fast, I think I got it 4 or 5 days after I ordered it. Right around $60 total.

If you have a 12/44 whats the top end speed?. Will 60mph make it rev to much?.I'm thinking of going with this combo. I wonder if a chain guide off an XR R will bolt up and give you the clearence needed?

I dunno about the Chain Gude Swap. The 250L Swingarm is more similar to the 650R/650L in respect to width and mounts/ etc.

At 60mph my bike is turning about 6500rpm with 12/44. (stock would be about 5500). It doesn't sound like much of a difference but its huge on the trails. Overall the top speed at redline goes from 96.6mph to 81.1mph (like the stock L could ever get there)

I picked up a spare sprocket carrier for my cush hub and I found out that I can switch between 12/44 and 13/40 without a new chain. BUT, on 13/40 my chain adjusters are two notches from the end. :confused: I just want it for DS around town though. For trails I go to 13/44 or 12/44.

FYI

13/48 combo is a 3.69 reduction

12/44 combo is a 3.67 reduction

Stock R = 3.69 reduction

Stock L = 3.08 reduction
