Would this work?

Would I need to SVA the bike if I cut the rear of the frame off and moved the mounting points?

More importantly is there any specific grade of steel I would need for the new shock mounts?

Is this your First Build Jevi ?

Any modification to the frame that require cutting it puts it into MSVA territory. To a large extent this has been ignored in the past but things are changing with regards to modified bikes.
As to your grade of steel question... no, but stay away from air hardening steels or exotics. Normal low carbon mild steel will be fine.
As long as the mount is suitably designed, of sufficient strength and can be securely mounted to the frame, then it's OK.

I've hardtailed my bike frame & haven't put it in for testing, but I know I'll have to at some point.

Yup.
 MSVA isn't difficult, especially for a bike if you build to the manual. Just a pain in the ass getting it done.

Not something I'd admit to on a public forum? ::)

I know, but if it gets flagged up I don't lose the bike, it just has it's registration rescinded, so I can't ride it. Then it goes back in the garage & gets modified until it passes. Not my only vehicle, not the end of the World.

Just to let you know the bike pictured is from a Russian website. 

This will be my first build because I've given up on the trike idea- 8 years since I first signeMore d up to the  world of the monkey and I'm sick of being stuck with no bike especially now my oldest son has recently got himself a 125 and keeps taking the p##s about me not finishing anything.

Anyways  there's nothing stopping me from making a  couple of alterations  - changing the tank and altering the shock mounts.

The main engine cradle will stay, the swinging arm will stay in it's original position and the front forks will go back on to the  keep the same rake.

This time next year?

Good luck with this. We expect progress reports and pics (especially the pics). :D

Just a quick update.  I've started the rebuild!

First job clear the garage, rearrange everything and build a new workbench - check

Next breakout the new toy - cut-off saw and build a jig to hold everything straight (I'll post some pics when I get it finished - promise)

A frame jig ! :o
What, no bit's of string and a length of angle iron ?
Are you sure you're on the right site ?  ;) ;D

;D

Angle iron,string ? ::)

 ::) D'uh. Elastic stretches too much and round bar keeps rolling away.  ;)

;D ;D ;D

All sounds very posh and professional to me ? ::)

Not being posh or professional just practical, new bench is too high for me to work on if I stand the fame on it plus my vice gets in the way and not owning a proper uppy/downy bike lift/workbench (I know our illustrious leader has one for sale but its a bit far away and outside my pocket money limit) I will have to manage with what I have - its the type of lift that fits under the frame rails and acts like a big jack.

My intention is to make a jig that will bolt across the supporting arms and carry the frame, holding it in place so I can fit various bits back on and cut off the bits I don't want.  I've managed to acquire an old hospital bed frame from work that is providing the raw materials for the jig (box and rectangular tubing of varying wall thickness - avg 3mm).

I have however hit a snag - my new cutoff grinder takes 180mm cutting discs (7" in old money) which appear to be only available on line.  The thing only came with 1 disc and I've worn away approx ¼ of that in 10 cuts - I have contacted the supplier (Lidl) who stated we do not keep spares/consumables for this product and proceeded to redirect me to a German website which was fine until I realized that they don't stock the discs either.

Moral - Stop buying stuff that appears a bargain (cheap) cos it will cost you more in the long run.

Anyway onwards and upwards - pics to follow

Lot's of cutting discs on Ebay and so on, just do a search for 180mm discs.

Packet of hacksaw blades? and think of the beneficial exercise effect....................I'll get me coat.............

You can buy a small angle grinder for about £20? And cutting discs are cheap enough from machinemart
