Hey all..

Im starting a rebuild on my 01 KLR 250 that I just picked up as a project.

Im looking at some motor mods and im curious if anyone has ever done a 300cc size big bore mod.
I have all the shop tools and such to do a one off build. I was thinking of boring out a 250 cylinder to the needed size.

Has anyone tried this before or heard of it being done.

Try a google search

 

I did..
Most of the kits in that link are standard bore size or just slightly over.

I was mostly hoping to talk to someone who has done it already.

 

Join the ADVrider forum then go to Thumpers, find the KLR250 thread and ask there. I do not know if klr.net includes 250s or is 650 exclusive.
