Hi there thought some one may find this vaguely interesting. its my YZR 4/7

Its a 1990 FZR400RR with a YZF750R engine in it.

it has a GSXR 400 RRSP rear shock (fullt adjustable) with home made linkages, FZR400RRSP head stock with forks (fully adjustable), Home made rear sets- made with help of original setup.

R1 rear standard can for MOT, it Has Stage 3 Dyno Jet, K&N filters and a mild Gas flow.

The original engine placement was done by a bike shop called Streetfighter (now closed down thanks fully), basicaly they made a complete balls up of it!! After the frame cracking for about the 3rd time, the Engine was taken out, re-aligned and any week points on the frame were welded up and heavily braced from behind the frame rails (see photos).

The electrics are essentaily a dogs dinner mix of 400 to 750 joining, most things are similar, but a few things took a LONG while to finaly sort out. it all fits now though and is a PLEASURE to ride!! i raced it for a while in the 1300 open race series, won few cups and came second in the championship twice in a row.... not too bad against R1's and GSXR1000's !!

she's finaly been put back out to pasture on the open road as of today!! woooot

(if anyone has any questions or owt, i would be more than happy to reply!)

Cheers, Dave.

That's awesome

Get some pics up with the fairing on.

Cool Project Dave!

Outside of the currently missing bodywork, 'bout the only thing that gives this Beast away is the Bazooka-sized end can.

BadAss Sleeper Dude!

Though i best add proof of racing.
