rake angle alteration

Im pushing my forks up through the yokes a bit tomorrow and and not sure how far to go to get the right reaction. Has anyone else had a go and if so how far did you dare go? Im considering 20mm.

Generally consensus is that on the curvy the most you can safely go(not measuring the fork caps) before bits you'd rather not, become intimate with one another on fully compression is 12mm-15mm. Without have checked it myself I'll say maximum of 12mm.

Easy to check yourself. by lifting front end up, undo the fork caps and slowly lower bike down till fork bottoms out. The distance between the dust seal and the bottom yoke is what you have available to play with assumming other parts that shouldn't be are not touching one another.

Cheers Ben that is an awesome reply, Ill do what you recommend and will post my final dimension on this thread once is it tried and tested.

Thanks again,
Rich

As an aside why do feel the need to push the forks through the yokes? Having problems with way the bike turns etc?

Remember as standard the Curvy 'S' model should have the forks flush with the yokes(not measuring the fork caps). 20mm(which in anycase as said in other post is possibly dangerous) IMO is a lot especially if you are planning on doing it in one go.


I'll say, start with 5mm nad see how that feels.

Im overhauling my handling at present, ive just fitted a set of diablo corsa pros and some hagon progressive fork springs.

In answer to your question im trying to increase the rake angle by recommendation of his royal highness Ron Haslam!

Try shorter dog bones they will raise the back up by 25mm and give you a steeper steering angle!!!

10mm at the front is good drop and with shorter dog bones as Billy says will lift the rear up giving a much more **** up head down position.

Might be an idea to fit a steering damper if you are trying to add as much rake as that.Small changes to the geometry can make quite a bit of difference.

10mm down on an SV shouldn't need that, generally, unless you're already marginal.

As above, we dropped a K5 SV650S down by 20mm to try and get the bike lowered with the dog bones as well and this was too much, the dust seals were toutching the bottom yoke. If you're not sure how much you've got left put a cable tie around the fork stanction and pull it down to the level of a dust seal, go out for a ride and when you come in the gap between the lower edge of the cable tie and the bottom of the bottom yoke is the clearance. This assumes you have bottomed the forks out at some point.

21Quest's suggestion bypasses such guesswork though
