iv to do my fork seals as the bike has been sitting a while in a cold damp garage and theyv started to weep,i was wondering what fork oil people use(and how much) also i was wondering is there anything you guys do to your forks to make them perform better? i have a hagon adjustable in the rear so it handles very well and would like the front to match it

After riding mine for a bit they're way too soft. I've not had good results in the past with harder fork springs but have heard wonderful things about fork valve emulators www.xrv.org.uk/forums/product-reviews/39172-ricor-intiminator-front-fork-inserts.htmlThey do a 41mm which I assume would fit a NTV. Or racetech in the US:
but this stuff will come in at $300 plus for me, so I ask if anyone has had reasonable results preloading our forks with spacers and if so how much? Thanks chaps. |

this stuff will come in at $300 plus for me If you're interested in emulators, I would get in touch with Hord Power. The Hawk front forks are very similar to the NTV and Hord is a widely acknowledged expert on Hawk suspension. Another option is trying to find a set of CBR600 F3 forks (although they often still fetch good money). You can swap the existing bottoms onto the CBR forks, so you get the existing front wheel/brake/speedo take-off with the CBR cartridge fork internals. The only downside is that I think the CBR stanchions are longer than the NTV ones, so you would need to swap to clip-on handlebars. I think the VFR ones would work out a similar height to standard NTV bars. If you want to play around with pre-load, I have heard of people using PVC waste pipe. I'm not sure how good it would be long term, but if you want to try different amounts it's cheap and easy to cut to whatever length you want. Just a final thought: I have an NTV600J, which came with much harder springs than later models. These were much too hard for me and I soon swapped to progressive ones. You can have my original ones (they are about 2/3 non-progressive spring, 1/3 spacer) for the cost of postage, if you're interested. Drop me a PM if you are and get a photo and I will work out postage for you. |

Funny that as the J had a much bigger air space in the forks 182 as opposed to 123 that would make it softer.
For the plumbing pipe in my BMW K75 that has spacers from the factory that look exactly like plumbing pipe and they work, funny as I was thinking of very little preload like 15mm max.
A nice offer but to New Caledonia I'm worried it would still be expensive.

I was wrong about them not being progressively wound, but they are quite short with looong (20ish cm) spacers, see pic below. PM me if interested.  |

Well just changed my fork seals, but of course the guides need changing as my seals were welded to the lowers.
I am intrigued by the slightly longer springs in the J model but with much less oil and a bigger air gap that must cancel out the longer springs, bit of a dark art this suspension stuff.
I'll give mine a good run as is and see how they feel, but they've gotta come apart again for new guides.

Went out for as good run today about 100 miles with lots of bends, with standard K springs and Haynes specified quantity of 15w I liked it, perhaps too hard for some as I'M 100kilos.
My first proper run on it very pleasant.
