CRF Susupension

After months of waiting for SMR magazine to be sent to me in Australia from my sister in was all worth it. I now have lots of questions........

My question is....has anyone done the suspension mods to their bike similar to Bostrom's CRF? By that I mean revalve/heavier springs, but not lowered the suspension stroke, only lowering the bike slightly with an '02 link arm and by lowering the forks in the triple clamps?
It seemed simple - I just wondered if anyone else had tried it.
Also - it seems like a lot of people are using the CRF in the states - has anyone tried putting a 5-speed tranny on their bike? I know a guy who has a YZ with a fifth gear fitted.......I was just wondering if the TLD team etc still use a four speed gearbox?
Is the jury still out on a 5.5" rear rim over the 5" rim?

our 2 sit 35mm lower front and rear , heaver springs , different valving , and heaver oil , they are lowered internaly , we tested them back to back ,as we done one and tested against the other wich had been done to the same spec apart from the lowing part. by the end of the day the lowered one was only about 2-3 tenths faster but so much more stable and smooth which made it easer to ride consistant fast laps.So now they are both mini me's .

Are there many differences in setting up and 04 to an 05?

Are you using the stiffest springs available? 0.49kg fork springs? What about the rear shock?

And is there a general spec for valving - because there aren't too many suspension gurus in Australia on the west coast who know supermoto.
why dont you contact mark willis and ask where he got his done ,he is very fast and smooth ...
and we have 0.49 fork springs that are cut so makes them heaver ,heard yesterday some of the guys oer east running 0.52
rear spring was the heavest one that honda made
as for shock valving we used ones from nsr250 shock a lot more to choose from
