You've been mostly-dead all day.
DTT BOTM WINNER
Not yet. I got it running about 10pm last night. The last time I test rode a dirt bike that late the cops drove by. I was doing laps in the back yard, drunk and raising hell, so no surprise there. Haha. I plan to ride it today- just need to clean the tank.SONIC. said:You ride it yet?

JAGspeed said:Great bike, like what you did with the head. I've got a 99 DR350 Dirt model but made it street legal. I did tons of mods to mine, DRZ400 piston big bore (453cc). Keintech airbox, 37mm FCR carb. porting. DR350SE stator and CDI. My bike rips now.
The reason I built my motor was my original motor had a catastrophic failure. These bikes are notorious for the pin in the counterbalance gear to come loose and push trough the hole in the crankshaft that lines it up. This causes the crankshaft and counterbalance to hit and blows it through the cases. Jesse at Keintech Engineering has a fix for it but you need to send him the counterbalance gear and crankshaft. There are plenty of DR's that never have this issue but it SUCKS when they do. If you ever tear it down you should definitely get it done.
Good luck with your build.
My cylinder was an LA sleeve modification. The DRZ piston is 90mm and did require me to machine the head some to keep the compression down so I could run pump gas.irk miller said:I haven't read about the counterbalance issue, yet. Thanks for the warning. The plan is to street this one too. On that DRZ swap: Was it a DRZ sleeve or one from LA Sleeve? I have an 89mm piston to do a 441, but no sleeve. I hoped the Eiger 400 would give me enough meat, but they don't. I found a DR350 jug at a salvage that happened to be re-sleeved and bored to 86mm. I have no idea what piston they used for 86mm. Unfortunately, they turned the base of the sleeve down to 89mm, so now I search for another. It's been suggested that an XR400 big bore sleeve, which utilizes an 89mm piston might work.
