So currenty I'm fitting the b1h tail on my g2.
I've modded the frame following scoobs guide, however just wanted to throw this out there. I love high tails so seeing as I've got to redo the seat and rear anyhow if I extend the lower sections of the subrame surely this could raise the rear. Here's what I've got so far:
I know they're way too long but it's a mock up and if I can get it right I'll get I welded.
I figured this would change it visually without messing around this how the bike points - dog bones-
Any opinions?

I've modded the frame, got the b1h fairing on it no problem. I'm going to make a custom seat to fit the tank and tail nicely.
All Im thinking is about raising the tail up by extending the lower sections with the bits I made in the picture.
Here's the b1h on the g/j subframe though:

Also I'm yet to fit the rear seat/cowl clips, but I am aware I shouldn't have cut them off!

Also I love how high and pointy your tail is. That's what I'm going for

i did use the j frame originally ,but im a fussy fucker i found my angle to low and my seat unit the line didnt match the seat line it sloped down to the rear ,i also didnt like the battery box hanging out the bottom either so thats why i changed it,but still wasnt high enough...but i found when i lifted the seat the mounting holes of rear of tank move out of place and also the gap goes out of shape were the tank lies along the main frame ,and also im a short ass so im now on tiptoes lol,it will work but i personally keep the tank in place to see were the tank lies when you move the frame up higher as the pivot point will make the angles change if that makes sense

also another way possible to change the angle and will keep the weld away from the oustide of bike,, if you cut the weld right at the rear of frame thats what i done with the b frame, so when it gets re welded its under the undertray area so it wont look rough and out of sight not sure if it will work with the j but worked a treat with my b frame

I picked up the b frame for like £80 off eBay from someone who was breaking, sure it was some kind of chop shop as he told me it was because he went into a car but I saw the front fairings and forks there all fine.

Yeah its making sense. ill be sure to keep the b frame then so future possible change. Hoping to get this all sorted before June. Just got to go for it I suppse. I'll make sure i leave the tank in place to see how much I can get away with.

Including what's on at the moment I've got my modified j frame, standard j on bike and slightly butchered b frame. Did you switch to the b battery box when you swapped over with welds. And did you extend the lower on your b then?

Scoot is your man on this, But here are a couple simple things you can do right away.
First loosen the 4 sub-frame bolts & pull up on the sub, There is room for some adjustment there.
Pull up & have a friend crank down on the four bolts, your rear seat will now be 6-7mm higher.
Now have some linkage links (dog bones) made, about 3mm shorter from center hole to hole.
That will really raise it up.
Here's my bike.....

Before the tail swap But the rear is much higher than stock...

See that tail makes it SO much nicer! And for me the higher the better.. Within reason not into the whole German tail streetfighter thing.lol
I'll give that a go this weekend. I think also a stubby can may be in order at some point.
Big problem is time. Wish I could get my bike in my flat.
Thanks guys for the input


Now we've just booked a track day at brandshatch.. So won't be doing anything fairing-wise until after. Just Incase! Beginning of May it is.

Yh I see what you mean bout the taper. I'm going to do the dogbones and try lifting it before the tail change. And will make sure I get before and after a for each bit.
The stubby cans are a great look aswel.
Also I note the 58 on the side!
