Upgrading the internals on stock SV forks?
 

I have been wondering around on this forum for some time, but haven't found what I was looking for. You all know the most urgent modification on the SV, which is mounting better springs and thicker oil. However, on the website of the Minitwin Championship (especially this part http://www.minitwins.co.uk/suppliers/mhpexhausts.html) I found these two options:

Product Fork Springs & Preparation (Maxton)
Machine Suzuki SV650S
Price £ 300
Comments Includes modified internals, springs and all preparation

Product Fork Springs & Preparation (Maxton)
Machine Suzuki SV650S
Price £ 479
Comments Includes complete revalve, springs and all preparation

Is there someone out there who can tell what they mean with modified internals or a revalve on the stock SV fork? GSX-R forks aren't allowed in the Minitwin Championship, so this is definitely for a stock fork. But that's damping rod fork and not a cartridge fork... :?:

Any help would be appreciated. I'm still looking for something better than the stiffer springs I already have in my fork right now. :thumbsup:

I'd drop Maxton a line, see what they have in mind. I think they're a Race Tech dealer, from memory. As you picked up, you can't revalve a stock fork since it has no valves ;)

Will try that. Hopefully I get an answer, although I don´t live in the UK.

I thought that perhaps some members of the forum who race in the Minitwin championship would have some experience with this sort of modifications.

:shock: :shock: £300!!!! Christ!!!

it took my dad and I about 2 1/2 hours on saturday to fit hagon progressive springs and 15w oil to Daisy. And we had neither clue nor experience, just a haynes manual and a torque wrench.

The springs and oil only cost £62.50 (full retail, inc vat), so how many cups of tea were they planning to make whilst they knock out your springs and charge you £237.50 for the privilage?

I'll upgrade mine on Saturday with ohlins.

Just having trouble getting 15WT oil. None of the local dealers have it in Stock - not even Hein Gericke.

I wonder why as 15WT seems the most popular choice.

Well, it's not about the springs alone. As you can see they also offer modified internals and/or a complete revalve. The thing I would like to know is what that means on stock SV forks.

I imagine a revalve would be adding emulators.

I've just gone from using 15w oil back down to 10w and now wish I'd never gone with 15. With decent springs, the right amount of fresh oil, and the correct air gaps, I've found that 10w makes the front end far more pliant and rides over irregular and corrugated surfaces far better.

Compression and rebound seem markedly improved. Okay it dives slightly more than 15w but once you're aware of that then you adjust your riding accordingly. I'm now convinced that a thicker fork oil just masks the SV's basic suspension traits and actually detracts from it's efficiency.

No need. My husband does the Ohlins setup for half the minitwin paddock for alot less than that!. Involves, Ohlins springs, Racetec emmulators and oil and spacers and works superbly well!.

BTW MHP send the majority of work on suspension to us now - Mike update your site!!!

Not sure what they mean by modded internals though but simply fitting springs and emmulators is good enough for most people road or race. If you can outride that front end setup that way then you should be on the grid and not sat at the traffic lights :lol: :lol:

LOL wondered when you'd see this thread.

I'd just like to say i would recommend Steve Jordan Motorcycles to anyone regarding Suspension setup/service. Steve set my forks up for me last year and now has them back again after i decided i prefered them bannana shaped and will also be supplying and setting up my ohlins shock aswell.

Also he's a nice bloke aswell and would probably quite happily give you any advice you need when requested(although not atm as he's besy with my forks LOL!!!).
