Cheap front fork fix!

[08hyper]

OK I had to do something with my front end, just too soft & mushy for me, but before investing for a high dollar fork cartridge kit, I decided to see what I could do with the stock fork first.

I did find out that the stock springs for the 08's & std 09's are 0.65 too soft for my weight, 225lbs+

So I contacted Lindemann Engineering, new (owner Ed Sorbal) at 408-371-6151 and commissioned him to make me a set of custom springs to my spec, basically the springs I had made are perfect "drop-ins" with stock dimensions but with a spring rate of 0.85 cost of the springs are $175.

I used Golden Spectrol 7.5w fork oil (stock) and set the air gap level at 120mm with the forks collapsed.

Now with 2 track-days on the newly sprung front end, guess what? their not bad at all, really good in fact, with the help of the track suspension specialist (at the track) I got the suspension front & back dialed in, and can now say that its never felt better.

I did trade bikes with Ben (mental999) for a track session at Laguna Seca, his Hyper has the Ohlins cartridge fork kit, and while his forks worked good, but for me, not necessarily better than mine, so at this time I will not be rushing out and getting a fork kit any time soon. Thank goodness.

Moral of this story? try making the stock stuff work for you first, you might be surprised & save some some money! Aloha Alex

and what did you do?? was a pic forgotten?

you can add a 10mm piece of pvc to each spring to make your springs harder

Hello Alex,

thanks for sharing your findings. You didn´t say what model you had, is it an S with Marzocchi forks or base model with Kayabas?

What sag numbers have you been using for static and race sag?

We usually use 5mm static in the back and around 25-30mm race sag in the rear.

The forks are being dialed in at 1/3 of the travel race sag, forgot about the static sag. But that is coming from the Superbikes.

I'll answer for him. He has a 2008 "S" with the Marzocchi forks. However, even the 2008 standard had Marzocchis. It wasn't until 2009 that they used the Kayabas and even then they switched back to Marzocchis for 2010.

What is the stock air gap for the KYB's.I have a 09 S model.

[freezer16801]

I weigh a bit less than you and racetech recommended .90kgs. I set my air gap to 110mm and it is definately too little.

Totally agree! I did the same thing with new springs from Traxxion Dynamics and I weigh quite a bit more than you, and it made a world of difference. $120 for the fork springs + $110 for the shock spring + $225 in labor for the install = totally non-mushy Hyper!
