Suzuki DR200SE Head Swap and Carb Upgrade | Fixing Low Compression

[@Rocketman0407]

Great build. Glad you did a carb swap. Dr200 has a really oversized cv carb originally. Switching to vm26-606 or 24-32mm PWK transforms this bike completly in terms of performance.

Sounds like I made the right choice! Thanks

[@Rocketman0407]

@@ozarkgarage definitly. You could put on a cheap exhaust as well. There is some restrictions in the original one. From there remove the airbox lid or put on a podfilter with some water resistant bag over it and the Bike is completly free of any restrictions. Going down to a 14 or 13t front sprocket will make it more fun as well.

@@Rocketman0407 I do worry about water if I get rid of the stock airbox. The muffler on the bike has already been gutted by a previous owner, not sure how much I would gain with a DG exhaust, other than probably better sound.

[@Rocketman0407]

@@ozarkgarage ok, then there is no point going to a DG exhaust. If you drive in very heavy rain the pod could be a problem. You could get like a 45 degree intake tube. Cut it to the correct lenght then install it so the pod ends up under your seat. Then put on a filterwears prefilter for added protection.

That looks like some good fun…..as always very thorough explinations

[@ozarkgarage]

It's always interesting to find out what lies down in the rabbit hole!

[@drumwhacker]

Is there a gasket for the rocker cover or does it just use permatex?

[@ozarkgarage]

The manual specified Suzuki brand sealant but I used ultra gray permatex

What is your jaltitude and jetting on the vm26?

[@ozarkgarage]

I think I ended up with a 17.5 pilot jet and a 185 main, tuned with a wideband o2 sensor setup. Same hill test as in this video: kzbin.info/www/bejne/e5a7pKBjhstpaKc Altitude is 800ft MSL or so, and never changed the jetting when I took the bike to Colorado. It started and ran just fine at over 12,000 ft (Cumberland Pass).

You me Yamaha Blaster 200. Not a Banshee 350.

[@evannelson4479]

Should have used the a 1986-88 TM-28 side slide carb! Way better than the mediocre BST-31 diaphragm carb on the later Dr-200.

[@Rocketman0407]

That BST-31 is a piece of junk. He did get in a VM 26-606 wich is a pretty good alternative though. The TM28 pumper is of course the best for this bike, but its like 300 $ new and rarely sold used. They sell it on some scooter website. I think going for a PWK carburator is a good middleground. Original OKO is good and costs 100 usd or so. The VM26 he used is a close second. There is also the Nibbi 32mm that works good if you want maximum top end power.

How many miles on this bike to get that bad?

[@ozarkgarage]

About 10k miles
