@DTR-NSR thanks! checking for a spark will be next on the cards! If theres no spark does anyone know the most likely causes? Or is that a stupid question? Guess theres plenty of reasons for not getting a spark?

@Calum I'll look into it once this bloody bike runs! Cheers mate

@Calum So a 97 dtr can be fitted with a servo? Bit confused mate haha

@DTR-NSR ok, definitely possible and sounds like it could be the case! I'll have a look

@NINJA Thanks fir the tip mate, yeah think the seal is now damaged, but think the damage was caused as a result of the sudden high pressure build up, as apposed to me damaging it on assembly. Cheers for the pointers

@Calum my dtr doesnt have a servo style powervalve, it has the old style where you set it how you want it. Therefore dont think the ignition would move it. I agree the switch shouldnt have any effect on the dump noise but it deffo did. Bit weird, hence why i think i might have wired it up wrong somehow

The main concern is that it wont turn over, and that pressure (pressure that i dont think should be there?) is dumped when the on/off switch is turned to off.

@finnerz89 yeah, but it shouldnt stop the engine starting should it? So confused now haha.

No! Which i then realised, so when i tried it again i did have it off. Although that might have caused the leak initially i still dont think it explain the dumping noise and lack of ignition? Any ideas? Thanks for your help.

Hi, looking for some advice...

I rebuilt my bottom end and have put it back in the frame, connected electrics and put coolant in the radiator. I just tried kicking it over (about 10 kicks) and nothing happened. I then turned the on/off switch from on to off, and all of a sudden the bike released a load of pressure, it sounded like a dump valve. Did it once more (only a couple of kicks) to see if it was a fluke, and it happened again. To add insult to injury my coolant is now drip leaking from the crank sealant. Has anyone got any idea what might cause thise to happen or how to rectify it? Could wiring it up wrong have caused this?

Thanks
James
