Front spring upgrade

I want to uprate the front fork springs on my FJR1300A (2008 plate).  The brand names I've heard of don't do replacement uprated springs for my year of bike.  Can anyone recommend a brand to go for?

Ohlins should help for Yamaha,what`s the problem with yours?

FJR front springs uprate

Thanks for taking the time to reply.

I contacted Demon Tweaks having browsed their free catalogue in MCN but they said that Ohlins don't do anything for my year of bike.  Neither do Hyperpro.  My bike is a 2008.  I had the suspension set up last year and the report said that the forks had been set up at number one and that any future adjusted would require having the springs uprated.  As the bikes handling feels like it needs tuning again I was trying to find some quality springs for the replacement.

Your forks should have up to 5 settings on preload (spring compression),umpteen on compression and rebound damping. Also the oil can be too thin.

Fork oil.

I'm not sure whether new fork oil will solve your unspecified problem but I was interested to read the comments of a suspension expert in the May issue of Performance Bikes (page 88). He reckoned that,

"Manufacturers use 'initial fill' oil in the forks, which is utter shit. It lubricates and that's about it. Expensive oil has friction reducers and as soon as you swap it you'll feel the difference."

Checking the service schedule of my two bikes reveals that Yamaha don't specify an interval for fork oil and Kawasaki specified every 16,000 miles or 2 years.

It might be worth considering a fork oil change first

Thanks jaffa990. The 5 rings at the top of the forks are screwed in to number 1 so I assume that there's no more adjustment which is why the suspension specialist says that further adjustment would require new springs.  Your suggestion for the oil change is also mentioned by James600zx.  The oil change is a thought but if I can get some springs I would obviously be well to change these whilst changing the oil.

fjr1300

I had the model before yours,it was a fuel injection with a high tickover which i complained about because of crunching into 1st gear,eventually there was a recall which lowered the tickover.

Also keep them monoshock linkages lubed (no simple grease nipples) because they wear out and fail m.o.t.`s
