Also first test ride was a ooge success, runs really well now, and all the little changes have made it much nicer to ride. I just need to grease and adjust the head set bearings and that's about it.

It's quite talkey, but does indeed max out around 90/95 on the flat, seems like it's running out of revs, so might try one of the smaller cogs and see if it has enough grunt to pull 100+.

Pretty happy with it tbh. Excellent.

Jialing one will work/it's the same thing. 

Otherwise look at Xl185 ones

This place doesn't seem to exist anymore. The internet told me Agtorque was an agent for Jialing, but they aren't, so not sure if there is an agent in NZ anymore? Had a hoon on Ali & ebay but no luck so far.

Have done a few very short rides on this bad boy, and its running pretty damn good. Its quite nice to ride also, which is a bonus. At nats I did a 75km trip from nats HQ to a museum in Cambridge, and just to be safe, I decided to re-fill it before departing for nats HQ on the return trip. It went onto reserve in the middle of the road in front of the service station, which was a bit of a surprise, as I was told it would do 200km on a tank (6L) but had only managed 75ish. That's around 8L/100km, which isn't great. J5's bike which is very similar, and was pulling the same speeds, and is only 15cc smaller in capacity, used just over half as much from memory, so somethings not quite right. Its defiantly running rich, and often smells a bit gasey, but I cant find gas leaking out anywhere. Will dropping the needle make a noticeable difference? Cant really think of anything else to check/change?

I did manage to hit the metric ton in a two lane flat express way race with J5 though, so that's a new PB.

Also also, a person on TM who confirmed they had both racks I need, then ghosted me super hard when I tried to buy them. BUT I mentioned to a customer that I yarn to about shit old bikes, what I was after, said his best mate apparently has at least 6x CT200's laying around, so he is actively trying to source the racks for me, excite.

Here's a thought, is the petrol tank crossover pipe blocked? Would only give you half the usable tank capacity which would appear similar as using shitloads of fuel...

Checked the state of the air filter?

Yeh the filter is mint, looks to be new. It doesn't need any choke to start, so I'm fairly sure its running rich. Smells a bit rich too. I'll start by dropping the needle down a bit and see what happens.

Gave up trying to get factory racks for the CT, so slapped together a home made abomination from a random rack J5 gave me, with donor parts from one of the free Jialing farm bike racks I got from old mate in the hills. Welding poorly prepared (i.e. still had shitty powder coat on it) Chineseium steel was quite splatty. I also recycled rack off cuts and hung the lovely indicators J5 donated to me. (from an ER suzuki I guess?) Looks low at the back in pics, but is level IRL.

Then made a mount from more rack off cuts to hang a china rotapax off. I got two of them, but exhaust made it too hard to hang one either side.

I also modified the OG indicator brackets at the front to take the new units,

The barry spec mounting and wiring for the old indicators.

Then I investigated the muffler, the last baffle was shot to shit, it had lots of rust holes that had been filled with some putty, and the outlet was quite haggard. So I cut off the last section, fished out the remains of the baffle, then found a bit of tube exactly the right size and welded that on. Filled all the rust holes with weld. And then put on a silly looking little outlet pipe. Much better.

So just need to paint the rack and muffler, wire in the indicators, and then I can try remedy the nasty fuel consumption.

Definitely ER indicators. Local Suzuki dealer had them for $10/pair for years after keeping them from all the farm bikes. I guess supplies must be drying up by now.
