Has anyone done the fork mod for the XVS650??

Discussion in 'Cruisers' started by JakeG, Nov 6, 2011.

  1. Hi all,

    I'm interested to find out if anyone has done the fork mod listed on the V-Star 650 How to page http://www.650ccnd.com/mods/forks/fork.htm .

    My v-star was lowered (Julio Slam also detailed in the link above) by the previous owner and i seem to be coming close to scraping the pegs an awful lot when leaning into a corner. Like a lot of mods, it looks awesome but seems to interfere with the functionality of the bike. I'd love to raise the front a bit to prevent this from happening. The forward controls may have also contributed to the sc**** factor?

    I'd really appreciate any feedback on doing this.

    Thanks in advance for any assistance.=D>
  2. put a slightly bigger rake front end.. will lift the bike up a bit aswell.. give it an even more awesome look..
  3. haha that mod is laughable.

    running no front sag, thats great if you want the front end to ride harsh everywhere and lose front grip. will also slow the steering and put more weight to the rear of the bike.

    but you dont buy a bike like that to go around corners so you might be fine with it.
  4. Hmm that does not sound positive. :) would he result be the same with the billski fork extensions? (http://www.billski182.com/ForkExtensions.htm) really need some extra clearance.
  5. Funny, was just looking through those mods last week and saw that fork mod. Didn't seem like the thing I'd be rushing off to do with my 650 though. JimmyD's comments have nailed it, really. Might be ok if you're mainly looking at cruising freeways, but I'd worry about response even in average corners.
  6. We were doing that mod as a cheap way to get more life from faded fork springs 30 years ago. As long as you dont go stupid on it, it works OK. the Bike obviously wont handle like stock, but if you want to go around corners fast you dont buy a cruiser in the first place.
    If you ride to the conditions and within the limitations of the bike you should be fine.
    No guarantee's or warranties offered or implied, all modifications from standard done at your own risk, and this is all speculation cos no-one modifies their bike so it no longer complies with adr's anyway, right..
  7. Cheers for the responses all. Has anyone here done put fork extensions on their vstar? I'm looking at the Billski 3" to give a bit more clearance. They seem to get pretty good reviews online. Would love to hear feedback from anyone who has put on fork extensions.
  8. Years ago. A 750 honda came into the shop with extensions screwed into the end of the forks. I refused to ride the bike, the join where the plug screwed in seemed too much like a weak point for me. I've always gone for longer fork tubes.
  9. I see what you mean mate. Any idea how much longer fork tubes would cost? I'll have to do a bit more research I think. Was hoping I could go the cheaper alternative but I guess there is always downsides when cutting corners.
  10. I did the J Slam and installed 3inch Bilski extensions, made the bike difficult to handle at low speeds and cornering so I took them straight off, would not recomend them but love the j slam
  11. Thanks for the feedback mate. I've been doing a bit of research and there seems to be some valid concerns for the strength and integrity at the thread joint. Not really worth it I guess. If new longer forks were a viable option an not so expensive I'd go for that. I'm well over the scraping when cornering even semi hard.

    What about just reversing the J slam? Won't be lowered but will improve your clearance. It's easy enough to put back to normal.

  13. You still have a couple of options. Measure the fork tube diameter and see if there is something from a similar model that might be longer..
    Or build a 21 inch front wheel for it. Both will affect the handling.

    I think I'll give that a crack and see if the handling and practicality outweighs the low look. On another note, how did you get tapatalk to work for this forum on your iPhone. Mine says that the server does not allow it at this time. Strange.
  15. Thanks for the options. I had not considered a 21" wheel but I'll check out whether it's a viable alternative. I think it would look really good too.

  17. Cool, will join soon as its a pain going through full site on the iPhone.

    You mention that its easy to undo the jslam, just wondering if it's just a matter of:
    - taking seat off
    - taking weight off rear tyre
    -remove bolt from modded hole
    - replace in stock hole

    I know it sounds logical but often things are not as easy as they sound and I'd hate to start an then realise I couldnt finish only to have a bolt out.

    Do I need a any special tools? Is there much pressure required to lift the tyre or will someone lifting the back suffice?

    Cheers again.
  18. I haven't done (or reversed) the J-Slam so don't have any tips or tricks, but reversing is as you say - moving the bolt from the mod hole to the stock hole. To know what you're looking at, you may want to look at the instructions for the slam found here.

    I agree, the issue will be having the pressure off the shocks to remove the bolt and then slowly releasing to ease the head of the shock up to the stock position.

  19. I'm not a cruiser rider, (ZX14 owner), but I'll offer a few observations.

    Anything you do that alters the geometry of the bike will have some effect on the way it handles. Depending on what you change, that may be a good thing or a bad thing.

    Very respectfully - cruisers are called 'cruisers' because that's what they're for. If you want to go corner carving, the best option (both the safest and the best value for money option) is to buy a bike that was built with that in mind.

    If you want to alter the bike you have to improve its cornering, that's easy enough to do. The question is how much are you prepared to spend and what lengths are you prepared to go to? Simply adding a much longer preload spacer to the front springs is a very cheap and nasty fix. It does raise the front of the bike, and that will increase the lean angle which is possible before things start to drag on the road, but it doesn't address any of the many other issues that have a bearing on cornering performance. It will interfere with the normal operation of the front suspension, for instance. If you're only prepared to throw $10 at the problem, this is about the best fix possible, but if you have (say) a grand to spend, then a trip to a specialist suspension tuning house who specialise in sports and track and race bikes, will definitely result in a far better thought out and far better executed solution.

    The best blokes I know are Terry Hay at Shock Treatment, who's in Sydney, and Radar Dave Cullen, who's in Brisbane. I'm sure the Melbourne blokes could point you at somebody. Phil Tainton of PTR is in Melbourne somewhere and he's pretty good.

    You could probably dig a ditch with a guitar, but why would you want to?
  20. To provide a little more detail on the issue causing the problem, the J-Slam (named after its creator, Julio Hernandez) is a DIY mod to an XVS650 that moves spot that the rear shock connects by drilling a new hole and moving the bolt, thereby lowering the rear fender. It's done for the look.

    If it didn't cause problems (like the OP is finding), Yamaha would probably deliver them with the holes already drilled.
