@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

Hello @matt0084 and welcome to the forum. Amazing, what a choice for a bike at 17. Thanks for taking the time to say hello. Yes, you always have to start somewhere and the DTRE is a great bike to start with. That's where I started out learning about bikes/mechanics all those years ago and then the passion for bikes just spiked!

I have an ‘89 DTRE engine which I bought an ‘89 wiring harness and electrics for to install in a Derbi GPR frame. Anyway, it turns over but doesn’t have spark. I believe it could be because I am using a F4FU-00 Flywheel and a 3MB-00 stator. Could this affect it? I don’t know much about the numbers but the flywheel was the only thing that I didn’t buy with the rest of the electrics. I’ve bridged the kickstand switch, I’ve bridged the oil sensor switch. I’m really stumped… all of the electrics came off a running bike. It must be the pickup being incompatible with the flywheel? Could anyone point me towards the right flywheel for my 3MB-00 Stator please?

@ChuckSR86 Do you have a DTR or a DTX? [image: yamaha%20dtx%202006.jpg] or [image: yamaha%20DT%20125%20R%201991.jpg] I must admit, if it's light greenlaning, then you can get away with it on supermoto in the summer? Anything more hardcore then some knobbley's would be ideal. For simplicity, I'd be lacing a set of hubs with ally rims for knobbleys. That way you only need to swap the wheels and not the brakes.

@matt0084 Yeah, I only say that as it is a known issue where the cables get mis-installed and the servo doesn't operate as intended. I find that the alignment hole in the cylinder doesn't allow the valve to sit flush in the port. I always align the valve with the exhaust off to guarantee alignment.

@Calum That site is known even more year's!!!!!
