RZ/RD 350 & Misc. 2-Stroke Tech BBS

Thumper,
Was yours spewing coolant out of the cap area or out of the overflow tank like mine? Regardless I'll take a look to see if that piece is damaged. I'm thankful for any suggestions!

I put a different 1.1 radiator cap on just to give it a try. Unfortunately I'm never lucky enough for it to be something simple like that. I'm going to do a compression test and a coolant system test if the compression test yields no results indicative of an issue. The bike only spits fluid once it ...

I rebuilt my RZ350 from the frame up 2 years ago with just under 3000 miles on the odometer. The bike ran great, and still does, but at the end of last year it started blowing coolant when revved up after getting hot in traffic one day. I put the bike away and figured it was a blown head gasket. I p...

Hey slinger do you still do the oring and squish setting?

Many thanks again to everyone here for the suggestions!

I ran through a series of tests this evening, from everyone's suggestions, and after completing several and still scratching my head I found the culprit. I went from regulator to rectifier to stator and back and it was a simple broken connector in the old fuse box. The lost voltage was somehow coinc...

I had about 2 minutes worth of energy yesterday and I checked voltage at the main fuse, with the bike off, and had only 9.5 volts on either side and as soon as the key is switched on the voltage goes to zero. The battery is a steady 12.75 with nothing running. I'm hopeful to feel well enough to real...

KPKE, What automotive fuse box are you using there? I've looked ar some but they're all seemingly to high to fit under the seat especially with the cover on. MK thanks for more suggestions. This cold is pissing me off because I can't get put to the garage to check the suggestions provided by everyon...

I checked all of the fuses before I started any of this. I've shook the bike and turned the bars to the stops in each direction to no avail. Unfortunately I just seem to have come down with some nasty cold so the bike will sit for a few days until I feel well enough to do some of the test suggested ...

Thank you to everyone for the suggestions. As I've said I didn't see any failed connections or loose grounds but it does present like a grounding issue. Before I go pulling the harness I'll look over the grounds again and then check the components kjellz suggested. I come from a motocross background...

I went for a ride the other night and the fuse for my headlight blew. I replaced it and was good to go or so it seemed. I took the bike out today for quick ride and the bike sputtered and acted funny. It would clean up and run normal then start sputtering again. I It became apparent that it's an ele...
