Ok, first things first, thank you all ya'll for just being here!!
I have been going round with this one, so here's the long version:
I am in the middle of a complete build- my first- something probably in the middle of a brat and a tracker, but kinda Euro too. Narrow Avon MK series tires, etc.. It will have a remote master cylinder under the tank so I don't have to have a reservoir on the bars. Simple aesthetic, not a racer. I am running an 18" rear wheel (mag) from an SR500 and then the 19" mag up front.
The motor is out. I have cut off the rear end and fab'd up a new hoop. I just finished new upper shock mounts and have those in. I have been talking with Jeff in the custom shock department at Racetech, who is awesome by the way. He's got me lined out on all the particulars for clearances, sag, and all that meow meow. What I need is some advice on how to mock it up so it sits and handles right in the end. Am I supposed to make the top horizontal tube on the sub-frame actually sit dead level? That line would then mirror the bottom of the gas tank and also in theory the bottom of the seat (just saying, pretty parallel anyway, maybe not exact). Or do I go by the lower frame members under the engine? OR I could look up the stock head tube angle and set up the whole frame so that mics out right, in it's lowered stance? The new look will be a little lower than stock, but not a ton (and really maybe not at all with the 18" rear wheel, just looks like it). I have the forks sticking out of the top triple clamp 5/8" or so (like that aesthetic) and now have the top tube of the sub-frame at level. IF this is the desired outcome, do I jack it up in the rear 25% so when the bike is under sag it sits back down to where it is now? I will need these measurements when I order up the custom G3 shocks from Racetech. For now, I'll fab up some rigid stays that will keep the bike at the desired height until I can get all the stuff back on the bike and weight it.
Thanks for any advice!!
