We don't see any AG's around these parts...
BTW- After reading up about your 'namesake', I ran across an article written by someone who had a thing for Stand slop.

Some fine writing by someone... wink

Thanks for sharing!

Your test mule looks like a job well done I like that colour a lot.Those AG look a good solid workhorse for your countrys terrain. Did the bsa bushman have some connection to these one of the last bsa to be built in the uk for export im not sure but i have a feeling it used the yamaha engine when bsa was under control of nvt and was producing the bsa tracker/ rambler125/175 im sure you would be familiar with these models having an intrest in the AG's. Looks like you will be busy for a while biggrin thanks for sharing always nice to see models that we never got in the UK.

Thanks for the comments everyone. I seem to have an affinity for Yamahas with long, stable model runs! :)

texasT - yes the AG200central blog is me. Just a bit of silly fun really. It was mainly in response to the crazy following of the Honda CT series of Postie bikes here. The AG is way more capable and fun so why not support it? CTs are now out of control price-wise here in Australia, even for a junker. You can get a stuffed AG200 for nothing and clean it up. It would be nice to get a following like the Postie bikes I guess...we will see. People seem to appreciate the technical articles and service info so I will keep it going for a while.

hanzo - Haven't heard of the BSA bushman - interesting old beastie, will have to look a bit more into that one. Actually I have seen early, yellow AG200 models for sale in the UK, I think you may of got them very early on in their model run. Maybe you got some import ones? The AG200 (first seen here in 1983) was based on the XT200 and I think it was in response to two things - the worlds changing view on emissions (they had the 2 stroke AG100 since 1973) and the excellent Honda CT125 and later CT200 ag bikes. They have a great little engine, very similar to the TW200, TTR230 & the older XT225 Serow. Plenty of bits around to keep them going!

Cheers

The bushman name was resurrected as it had been used before on earlier bsa models based around the bantam in the 1950,s this bike was some of the last to be produced bearing the bsa name . looks very similar to the Ag and I think actually used a yamaha engine not built in great numbers about 700 I think all made for export .

Interesting reading there hanzo. Certainly a rip-off of the AG100 in the photos. It's interesting to read that they may of made a 200cc 4 stroke AG for the NGOs too. I have seen films of AGs used in Africa and there are soma anomalies in them...maybe that's why? They were not from Japan?

Yes very much a copy of the AG.The tracker was pretty much a copy of the early dt125/175 the only difference was the frame and cylinder head shape but the intresting part was the bsa was useing a monoshock it was not seen on the yamaha till about 2 years later.

now beleive it or not most people quote yamaha with the idea but the principle was seen as early as 1949 on the HRD vincent black shadow with a single shocker under the seat so maybe it was british idea !! but improved upon but it might have been stolen from germans because german manufacturer NSU was using it pre this date on there two strokes . so who knows

Agman does the AGS have the clutch lock feature. Like when you pull up to go through a gate you pull in the clutch and can keep it in gear with the motor running wile your off the bike. Chain maintence must be halfed with that full chain cover. Happy agging.

back in my farm days on my AG 100 the chain guards main advantage was in long grass stopping it fouling things up and with it keeping the mud Ext off chain life was pretty good .

We have the Honda CTX200, Suzuki DR200 Trojan, and the Kawasaki 250 Stockman. All of which outclass the AG200 in tech by at least 10~15 years. They don't tend to stay together as well as the AG200 under extreme abuse which seems to be everyday farming over here! Disk brakes wear out fast, as do single shock linkages, chains and sprockets suffer even though they are o'ring, and the Stockman's DOHC may not mix well with farmer service intervals!
Markvan - Yes they have the clutch lock on the clutch perch. Don't see much point in it when your gearbox is 5 up and neutral is at the bottom. Just a bit of a gimmick to try and sell against the old CT200 with the auto clutch I think.
If the chain enclosure was maintained properly it was great. The early AG200 had an O'ring chain and they soon found it was a bit of overkill. It's amazing how many get ripped off and discarded though, most can't work out how it all goes back together. :)

Nice collection and lovely results from the restoration.

AGman · Veteran Member

I probably should be more specific on the AG200s "Restoration". :)

Over here in Australia we have dry country farms and irrigated farms. I looked for a long time for a good dry country bike. Irrigated farms destroy Ag bikes irrespective of brand, two wheel, ATV, side by side. It is not uncommon to find neglected ATVs totally destroyed in 2~3 years on irrigated dairy farms here. My AG is an '08 model and it was from a dry, non-irrigated cropping property. It had a blown cylinder base gasket so the farmer traded it in. I bought it and stripped it back to the frame and freshened up the top end while I had the cylinder off.

I'm not sure if it was a restoration as such, no paint or polishing or anything like that, just a good strip-down and wash up really.

A bit like the TTR250; looked for a long time for one that had been looked after and/or not used. It has 2500km on it and only had it for a few weeks but have been lurking here for quite a while.

I wondered how you got it so original looking. Still, you can have your deserved kudos....

..but I'm still trying to find the kudos option though. wink

Thanks Jarrah

And for you blokes that DO actually restore bikes...if you want to see what your CT looked like when new I posted up the sales brochure on my latest post over on my blog.

No problems Agman.

I do know what it looked like when new, a far cry from what it looks like now (thank Christ). Although it would be good to check out your blog, but where is it?

Cheers,

Thanks Greg, my brother from another mother. wink

Nice write-up Jim, I had a good laugh and was well worth reading.

Just a note on the CT125's Jim- not sure exactly when they started but they finished in 1977, see HERE.

Funnily enough, the CT125 uses the same frame as the CT200 Auto-Ag and most components are the same also (wheels and brake panels, seat, tank, carb, racks, swingarm, chain case, fenders and mudguards, exhaust etc.).

The Auto-Ag also shared the same crankcase with the big ''H'' word ATC185 ATV's from 1980~1983 and uses basically the same engine from the ATV200 from 1981~1987 (including the Big Red). The crankcase was also used in the 1986 TR200 (along with others). The crankcase then went on to CTX200 for god knows how long. Note that these models used different left-hand side covers with the transfer shaft, some using a normal manual clutch. The ATC200M from 1984~1986 are they closest, they even share the starter motor and left side cases (unlike the rest that are not electric start apart from the TRX200 which came later on).

The CT200 Auto-Ag is basically just throw together of the parts that were already available from other models, bar a few components like foot brake lever, rear twin-shocks etc. (which probably came from something else anyway lol). It even uses XR200 fork gaiters with XL125/XL100 fork pipes and XL175/125/100 cable guides LOL. smile

Sorry I didn't put a link in but I don't like linking to my stuff in new forums until I've done my bit for them and posted a bit of useful content, and then ask permission from the mods. Having said that, I did everything but link to it in this thread huh? :) And someone else did it anyway...thanks Texas and mods can remove the link if they like.

The mods on here are very relaxed and, like most of the members, enjoy reading about dirtbikes - wherever that material sits wink

AG200 progress...

As she sits...luv those double stands. smile

Front end is complete...

...just need to install new tyre and these - $120 Each from Yamaha! I'm glad I found some second hand ones.

Got the donor motor cleaned up and installed.

Just have to change over the stator housings, wiring & connectors are a bit different from the earlier model donor.

Final drive, rear brake and axle assembly all cleaned up and ready to install...

Tomorrows job...clean-up rear swing-arm, install new bushes and get all the rear end back together.
