Onyx Mongoose ZX10 engined build
Discussion
Right starting a build diary for this little monster. The chassis is an Onyx Mongoose item which i bought from www.Onyxsportscars.f9.co.uk near Grimsby about two weeks ago. There own car is powered by a rover 1.4 K series lump producing 100bhp and weighed in at a little over 400kg and was quite impressive on the road and track but like most people i wanted more power and less weight. After contacting David at Onyx i was offered there last currently built chassis. (only 5-6 chassis have been made so far but the company has currently put it on hold to concentrate on other projects)
My first plan was to fit the Mongoose chassis with a Yamaha XJR1300 engine but due to issues i would have had with cooling a mid-mounted air/oil cooled engine would have been more trouble than it was worth. So after a couple of days searching i found a 1988 Kawasaki ZX10 at MP Motor cycles just at the side of the M606 Bradford and got it for £600 with T&T.
The Chassis
The bike
It actually rode quite well and it was sad to break it.
The bike after about 3 hours
All the parts now all over the place
XJR engine now straped to pallet awaiting collect. Its going to Ireland.
The ZX10 lump stripped of its casings and cleaned up. Had 19 years of shit to remove
A few parts removed cleaned and painted up.
Stripping and cleaning the carbs
3 already done just need to polish them up now
The exhaust will be reused. Had a nice stainless system on it with a Micron can
My 3yo nephew liked the bike. He was in tears when i stripped it
The finished product will weigh around 350kg and have around 140-150bhp. should be fun.

Thought id put up a few pics of the chain diff im making.
heres the diff from a 1.8 sierra
one side welded
side mounting plates cut from 5mm 316 s/s
I made the bearing housing from 3 rings of 6mm mild steel with a 2mm end plate.
The bearings im using
All together
Ive made this diff from s/s and mild to start with but i plan to make it from ali once ive tested it to make sure it will be strong enough. Once its all ali it will drop a kilo or two.

Engine is in but not fully fitted yet, its only in so i can mount the chain diff and other components.
The diff built up
Sat in place in the chassis, will be making the mounts this week.
Will be fitting the steering column and rack this week, just need to nip to the scrappers to get a Metro column.

Floor and side panels are fitted and the engine is now in and im sorting the loom out. rack and column are also fitted. I have all the suspension in a box out the way for now.
Sorry some of the pics arnt too good, done a 12 hour night shift had 4 hours sleep then been in the gym for 2 hours so im a bit f**ked and cant hold the cam still lol.
And a very locost pedal box (cost nothing to make)
