So, after changing chain and sprockets, I didn't get on with the bike and think that I may have messed up the ride height. I was pretty sure that I put it back to where it was, but want to check it before my next outing. I recall some time ago setting it to 225mm with the proper tool and am going to check its still there or there abouts. So the question is; with the proper tool do I set it with the rear wheel just off the ground (as recommended by Kyle racing pdf; and a pain in the arse to balance the bike that way) or can I set it ti an alternative datum with the rear wheel on the ground?? many thanks, Bob
Don't know if you can or not. But if you need a ride height tool, let me know and I can get you one sorted. The local laser company cuts them for about £35 ish and that's 4mm stainless.
I've set it it 225mm. Front forks are about 10mm raised from the yokes It was sat at about 235 which i suppose was why it felt a bit skitty at the back end. (taking the front fork height into the equation too) I suppose i should now take a measurement with the bike's rear wheel taking the weight and get a new datum. Right pain having to lift the rear end off the ground when setting the height... Cheers, Bob
Just checked mine. Bang on 235mm. Still waiting for the spindle cone to be turned but at most maybe 1 to 2 mm out.
@bettes I set mine to 235 but found it really skitty at the back end. Probably 'cause I also dropped the front forks through by about 10mm, put it to 225 and it was night and day different. But with forks not dropped would agree that 235 would be about right. My original question (in a quest for knowledge) is why is the datum ststed with the rear wheel unweighted; why not set it (less height) with the bike sat on the rear tyre; or even loaded with the rider? Weird, but must be for a reason... Cheers, Bob
Thanks for that, bob. After setting it I went out for a ride. When I got back I did the same as you and reduced it to 225. I went out again and must admit that made the world of difference and for the better. My forks were also raised so that could be why. Anyhow the bike feels miles better now. I'm trying to get it booked in this weekend for a suspension setup. I've got about 25mm of sag in normal clothes so should get to 30 mm suited and booted. All good to go. Cheers, Ian
Ian, Best guy I've ever used for suspension is Pete Clifford. Well worth a look. depending on where you are... Actiforce Racing He set up my 748 for £40 (might cost £50 now) it was like it was on rails when he finished. Met him the following year at a track day and he re-checked it and said there was no charge... I owe him beer...
@Cupid Stunt yeah, buts that's what I don't understand. The bike goes round the track with a rider on it! I don't understand how big the universe is either...
