The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

That sure is nice, indeedy-do

I will need to get a lug welded onto each of the ZZR fork legs to fit the Harrison calipers - I don't know what they were made for, but at least the lower lug is in the right place.

In my stash of parts I have a rear caliper off a Kawasaki ER6N - commuter bike which I'll adapt to fit. I have to wait for a call from Mike at TALON Engineering
( http://www.talon-eng.co.uk/ ) and drop the JMC s/arm off for him to machine and make a sleeve to match the spindle & bearings (20mm & 25mm respectively). I could get the work done for about half the price, but I want this bike to be "spot-on" so an estimate of 250 for a days work is what it'll be Most of the time is setting up the machinery. Luckily a mate is making the new stem for the yokes (triple trees)

I managed to strip the Harrison calipers down and give them a thorough seeing to with brake cleaner, at least that didn't cost me anything!!!!

Got a phone call Sat morning - from Mike at Talon and he's part way thru' doing the JMC modifications - so should be able to pick it up next week sometime

To match the Harrison Billet-6 calipers I now have...



.... I've found a loverly Harrison rear c/w hanger made for a JMC slotted swingarm !!!!



I've also been a busy boy this morning (skipped church ) and got the engine onto me workbench (OK - so its an old kitchen unit) and took the sump off for a quick looky-see......











So far, so good - all looks OK inside, gears look nice & clean and no visual signs of wear, even on the gear selector forks

What's all the crap in the screen? Is that normal for those motors?

Yeah, fairly typical for a 33yr old motor Most of its clutch friction plate and gasket goo. Its one of the only things that gets missed and can lead to oil starvation - but its only a mornings work dropping the sump insitu.

Here's a photo's of the sump from my Mk.II Sprint bike when I first got it...





..and it was running OK before I stripped it down... and did this to it using the same gearbox & crank :

Got all me REAR END stuff back from TALON - I had a s/arm pivot sleeve made, a wheel spindle & sleeve and the JMC trimmed down to fit snuggly in the frame :!:

I spent this afternoon getting the wheel lined up spaced centrally.





I had to make some bits myself - the wheel adjusters that fit in the s/arm recess & has the chain tensioner - I used s/s 8mm threaded rod for that.



The Harrison rear brake has a lug that fits under the s/arm and an adjustable cam on top to hold it secure.

The chain run will clear the frame by about 5mm but I haven't checked it in relation to the drive sprox yet



Just awaiting the new stem so I can fit the front end and align the calipers on the forks. I'll need to get an extra lug on each leg to hold the Harrison Billet-6's - this may be a problem as the fork leg alloy can shrink after welding - but my chap will take a look when its time If this is going to be a no-no, I'll make a couple of adaptor plates from 10mm alloy plate.

Bit more fiddling in the garage ....... Trying to get a rough idea of the set-up with the rear shox




Its a Showa off a Ducati 916...







Gonna turn my attention to the motor now - cleaning the sump gasket off - like "sh*te to a blanket"

Also stripped the clutch as the plates where stuck - the motor's been standing for a few years
