Hi all,
I pulled my old steed out from under the covers and brought'er back to life. I Bought in 1990 from the original owner. I stripped it down quite a bit and sold off most of the parts. It is a great trial bike and has never let me down. I hope to get out and explore Anza Borego this winter. I am in Southern California. Stay safe and Happy Holidays.

Its was Suzuki's 1st 4 stroke dirt bike. Trying to compete with Honda and Yamaha in that space. The SP's (dual sport) and the DR enduro were not super popular but parts are still pretty easy to find. I have put a DR skid plate and swing arm with the spring tensioner on it. The Clarke gas tank fits pretty well and is almost 4 gallons, go for days on one tank. Its is very friendly, has plenty of low end grunt, and I am lower to the ground. I like it and have grown very attached to it over the years. I have put many fun miles on'er from forest fire roads to desert trails. The engine has never been a part, original top end. Just change the oil regularly and ride within her limits which are very close to mine!

I am having some issues with hard starting and rough running. I cleaned the carb very well. Took everything out. I am thinking that the condenser is getting old and gets wonky when it gets hot. The points sit right on the cylinder head it gets hotter than heck right there.
Many years ago I had a problem like this on this bike. I had to take the point cover off to let it cool off enough to run. That helped. I replaced it since then but have not been riding it for 10 years or so. I used NOS condensers and my theory is that the electrolytic stuff inside is just old and does not work as well as it did when it was young... that makes 2 of us...I found what I think is a newer aftermarket unit on eBay..only could find it in the UK..parts are getting kinda scarce for this beast.. Any one else have condenser problems? Thanks
