Carrying on from my post and information receivedHERE and with the benefit of the WP spring chart found on this site:
... it appears I need the 97-250 spring (part number 9121.0008) for my 97kgs of mass. I presume that the weight's they're suggesting are net of gear because at a rough guess my gear (full leathers, lid, boots etc) must be another 15kgs? That would put me into a whole nother spring rate again -and one that's apparently not listed. Being a cheap/poor bastard I only want to do this once, so want to be sure I'm getting it right.
Checking with my local 'berg dealer it looks like the spring is going to cost about $240CAD ($215USD, or 116GBP), and I'm waiting still to find out how long it'll take to get here. This seems like a lot of money to me for something as simple as a spring. Can anyone else suggest whom else I might look to as a supplier - preferably in Canada or the NW US?
In the meantime, with regards to making-do with my stock spring (88-250) - should I try to acheive correct rider sag at the expense of eliminating static sag? Or should I only wind it up as far as I still have some static sag? Riding is shorted paved circuit and our local motard track which is paved with an MX section - large-ish (to me anyhow) jumps, table, whoops and berms with a <1m ramp on the straight. As mentioned I'm about 97Kg (215lbs) nekkid, and about 1.93M (6'4") - and, no that's not a personal ad before anyone asks Bike is an '05 FS650E.
Right now I bottom pretty hard - I'm sure some of that has to do with "technique" (if the word at all applies to what I do), but my back tire is also all over ther muffler just riding around sweepers (highway cloverleafs, or the turn at the end of the speedway) at a relatively moderate pace. The bike wants to run wide (I presume a result of it squatting so much at the back end) and I have to crank it over fairly far to track anywhere close to a decent line -to the point where the front-end will tuck slightly.
As suggested by Brian in the other thread - I'm actually sitting fairly far forward - definitely over the tank, but with a few inches of seat still to go before I'm actually riding the gas cap.
For fun I tried taking the sweeper at the speedway sportbike-style - hanging off with the knee on the deck. Without the benefit of the stopwatch or being able to see my speedo I can't say I was definitely faster, but it felt faster and the bike was more composed (likely more vertical as well). I think I was able to hold the line a bit better as well -but this may just be a case of me just being more accustomed to the position and willing to push the bike a bit harder - it's a much shorter trip to the pavement when you already have a knee on the ground
