Just bough MoBill's wr250r. The bike is awesome...but the rear shock blows. Coming from a mx background I want a little bit better suspension. I bought this bike for fuel economy and reliability. For comparison my other bike is a 950se. I dont think having it well sprung is too much to ask? Ive read good things about GoFast doing work but at the end of the day it's still a cheap shock. My first idea is to put the F shock. If the overall length is correct I can make it work. I am a custom metal fabricator by trade and have access to everything I need to make this work. I just need a little wisdom from the forum before I start. If, with your help, we can get this to work I would consider manufacturing. My questions thus far: 1. Will it fit or is it too tall/ short.(i know the mounting types are different but I will be making new ones)? 2. Has anyone done this or a similar setup? 3. Is there a better base shock to start with. The F ones are about $150.00 on ebay.
