Hi guys, got a question (s) about my GT200 oil pump.....the interweb is telling me to delete it and run oil/fuel mix. I'm not entirely convinced about this.

It's clearly an issue, I think? But, why remove the factory pump?

I understand they can fail catastrophically, but by the same token, I see that if they're not set up correctly the same can happen and it would not be the pump's fault as such.

There are some precise throttle cable settings and adjustments that have to coincide with similar alignments on the pump cable......adjust one and then the other, failure to do so could result in poor performance of the pump and engine failure....I get that much. If the throttle cable was adjusted but not the oil pump cable, the imbalance could contribute to the problem I reckon?

So, I don't feel like running 2T mix to be honest, it's a messy PITA....I will for the initial start up....a belt n braces approach and to give the pump time to prime. I have what appears to be a nearly new pump ......could I test it by attaching a drive to a drill and spinning it up with oil feeds and outputs?

I've heard some change the oil lines to clear so the oil flow can be visually checked, I like that and will do the same.

What lines do I have to find? The oil isn't hot (warm maybe) so rather than use the hardened lines the engine came with, what grade and size of lines do you use?



So....what do you guys reckon? Cheers - Colin

Hello, I have a question if I may?

Thinking it's time to source appropriate air filters for the Suzuki GT200 build. I have in mind the foam style, or maybe the K&N gauze type...but finding them in 34mm neck size is tricky tbh. Some do look like they're really poor quality, even the K&Ns look similarly poor....and the prices aren't cheap either

Seen these RamAir foam filters....anyone had direct working experience of these, of similar? I'm open to suggestions, but cannot use the stock intake system so pods is it.



Thank you.

Owned over 25 years......stock to not 4-5 years ago.







That's enough of that nonsense.....back to the Suzonda :)

Hi all, thought I'd introduce myself. My name is Colin and I live nr Oxford UK. I've been dicking with cars n bikes for a good few years now, 45 to be exact.

I'd owned a '82 CBX550 for nearly 20 years before hacking it about a bit.



That's not why I'm here though. I had acquired a bare Honda 400/4 frame which I got a V5 in my name so I could play with it.
I fancied a bit of ringadingding in my life so thought to build myself a two stroke flat tracker style run around.

I love a rummage around a swapmeet, and found a pair of Paoili forks and Honda NSR125 6xspoke alloy wheels....which was a start.
A facebook deal landed a Suzuki SB200 engine inc carbs, needing a crank rebuild.

A quick fit up looked promising, engine mounts weren't too far out, infact the rear upper was the same and the front just needed mounting plates cutting out. The underside mounts will need some work but nothing too involved...so it was good to go on the concept.



Needing a tank I fancied the look and style of a Honda CB200, loving the chrome strips and padded centre section....which would run into the seat I had in mind nicely.

Microns turned up next, they're for a 350LC but I think I can make them work?



Now this is where it get tricky....the NSR wheels are staying, but trying to make them work with the Paioli forks - disc/caliper alignment mounts all conflicted and meant engineering beyond my simple garage/shed means....so, NSR125 forks were drafted in to KISS....and a few attmepts at taper bearings sees them fitting a treat. The entire front end is NSR and should work well.



So, I now have the basic layout, including the seat unit. Did I mention the Suzuki GS1100E alloy swingarm? This is lovely piece of kit and it was defo going on whatever it took. It took a custom spindle turned out of stainless and slimmer needle rollers as well as a small cut across the spindle width to fit the 400/4 frame.

I now need rear spindle (Yamaha Diversion 600) tophat spacers making up to complete the rear end. A brake torque bar to secure the rear caliper and a brake pedal too.



Bars, levers and switches are sourced and should work, tank is close to being mounted along with the seat unit which will have a removeable padded seat (in mid blue suede) to acces oil tank and battery.

Due to the footrest placement being out of line with the kickstart swing, I thought to find a starter motor kit.....I actually found a GT200 engine, complete except for the barrel (which I have) along with 22mm GT carbs and 5x speed box of course. So full GT spec lump which worked out well.

Here's a few random images to bring you up to date, thanks for reading so far.











I plan on updating this thread as I go....I'm pushing this build to have a finished, running MOTable bike by Spring 2020. Lots to do as each part really needs to be thought through....one off builds are very very work intensive as I have found to my cost haha!

That's all folks.
