SOHC

Just have it as an empty chamber and it should sound like some kind of super car

I sold this to pay for the v8 rebuild but I had a go on a few of the later TS250s but I reckon the 185 ER is way better, if anyone has one of them they want to part with I would be keen. 

your not tempted to get an aliexpress bigbore kit?

I have tried sliding doors and butterfly valves in home made mufflers with much disappointment, you may get a slight change but the baffle chamber of the bit of the muffler that has been bypassed still will still do its job if any part of it is open to the exhaust flow.       

Ring a ding ding 

The 200 top end fits the 185

Pricing is model dependent...

'Good' condition ML7 with some tools ~$1k

Older ML4 or poor condition is few 100

ML7 with gearbox, or super7  2.5k + (though there have been a few sub 2k, bargains)

Mine had some tooling, I put it on Facebook and it was gone with in 16 mins. I dont like the bushes in the spindles, they are a pain in the arse

The price for myford lathes is crazy, I put mine here for $500 and no one took it

There are some B&S Facebook pages witch are good

Yeah. There were only ever 2 or 3 SC's came to NZ. The guy in ChCh who owned one moved to West Australia and took his with him.

So is the WR based on the last of the air cooled YZ's ?

My friend got givenan SC500, its just sitting in the shed he hasn't even touched it, I would say the WR is basically an early YZ engine, it wouldn't need much improvement with its power, only 1000 were ever made but they seem to all be in NZ

Is that the enduro version of the SC500 ?  The SC's make ridiculous amounts of torque - if you can master starting one.

The SC is the old 70s thing? I know where one of them is,the WR make over 60 HP

My friend has this Yamaha WR500 for sale, I want

Knew I had the pics somewhere. 250 Aermacchi motor with Honda alternator in place of the piss useless 6v generator.  I could also have triggered a GN250 ignition off the lump on the rotor - but left it with points as easier to repair in rural Italy.

Did you ùse the gn250 rotor and attach the hub from the aermacchi?

Can you get my bike changing? 

Your complete charging system is missing and there is half a chainsaw plug spanner in its place

I got a stainless steel one, they say you can crank them straight in but it might pay to run a 12mm tap as far as i can

Has anyone used these? Looks perfect for the striped oversize 8mm home thats now 10mm

Like this one?

Has a third position and a table on the opposite side to the jointer but all the mechanicals were gone by the time I got it, good saw, did our kitchen with it, just comically small and had to build it into a bench to make it useable.

Yes I think so, i didn't get a good look at it, just put it on the trailer, the o e I got had legs but not sure if they were factory?

They must be rarer?  Didnt know they did a 3 in 1.  Those saw/planer combos turn up pretty regularly.

 

Pics?

I don't have any pictures, I was getting some tools from an old guy and he sed I could have it as it was going to the scrap and I sed I would find a home for it, it had the Tanner embossed spanner and the thing for doing the angels and stuff, he had got it new.

I got given a Tanner saw bench that has like a spindle molder on one end of it to, it came with all the attachments.

I had a sl 360 scrambler for a bit that did good wheel stands it had a sportster petrol tank and the exhaust had been made to look like a shotgun, but it broke a cam chain tensioner and i dumped it

And 10mm lift on the exhaust.....What timing does that give you ?

Lots of power, 

Also the reed block I will chop out the divider and make a carbon fiber single petal   

I have been studying the TF ports, the transfer ports can't be improved on at all but the intake can be opened out and the exhaust port can be raised 10mm, when I finish this cylinder I will let you know my findings. I am trying to find a 32mm Mikuni VM spiggot mount carb to.
