Bike lacks power

@Ryan-F well you have your issue then it’s the powervalve yeah an engine porter should be able to do it no problem, the powervalve should whine as you turn the key if it doesn’t then there’s an issue the valve should be aligned through the exhaust port so that it’s a smooth transition as you look through the exhaust port there should be no step or ridge

It's like a 3RM model CDI. But to be honest, just get a Zeeltronic for it. It'll be better in the long run since it will be new, rather than buying something old and potentially faulty.

@Calum Ok thank you, do they come with like a base map at least?
was looking at getting another top end and getting it ported also.
@Ryan-F Zeeltronic provide an array of maps that you can base yours on. They are more aggressive than the OEM maps. I've just left it as the one they provided. I altered the powervalve timings but that's about it IIRC. Best get the handheld programmer too. I found mine came with some crazy map that was totally inappropriate.

@Calum Ah ok thank you for the help, I was looking at the older CDI's but like you said alot of them look crusty and I know what you mean about the zeeltronic that is going to be my next buy 100% I don't want to make the bike crazy or nothing and i don't want mega horsepower I just like the torque and acceleration.

Depends where you pin it.
So it's not a clear cut answer.
On an unrestricted CDI a pinned powervalve would be detrimental to performance.
On a DTRE/X Ignition, a pinned valve will allow you to rev past 9K.
On a CDI where the ignition is severely retarded past 8K then it will be a loss of power all round.If the CDI allows power up the higher revs, but, like the RE/X ignition, retards the powervalve, pinning it open will allow you to get that upper power, sacrificing low end.
It's not clear cut. For optimum performance, set it up properly and leave it alone.
