YPVS unit

[maser01]

Hi all,
looking at sending my faulty YPVS unit to Nick in Greece for repair & adjusting mod. Anyone have some feedback on his work pls?




TIA,

T

I had 2 500 and 2 350 units modded by him And all 4 work great. Curves are easily changed using the dip switches.

Had a Honda PGM 2 RC circuit repair and de-restriction mod done. He's an asset to the community. I will be sending one of my YPVS units for adjustment mod also.

Ok thanks guys...........on it's way to Greece tomorrow. Will be interesting to see how long it takes in these times!

Just got a used one but need to swap it onto the bike

i sent a unit to be modified by him, it lasted about 15 minutes then stopped working, he told me to return it at my expense which i did, when i got it back still wasn't working, i told him but he insisted he had tested it and it was okay, i put a standard unit on and all was well, i would never use him again thats for sure, think your better off using a Zeeltronic set up which i now use which has made a big difference, i am running a Rd 500 bottom end and 350 ypvs heads and barrels using the standard stroke 50mm making 654cc, wondered if any other members have a similar set up

That setup would be interesting to see.

Sounds like an obvious mod but I've not heard of it before. Does it run well?

Yeah, soldering on the backside of a 20+ yo PCB can have it's culprits.
I also managed to destroy PV controllers. My suspect is that the main IC didn't like punctual extended heat.
(for those interested: Here's what they modify

My advice regarding this issue is anyway a complete ignition/PV controller because it removees 3 of the most common sources of trouble (stator, PV controller, CDI) AND adds performance in the same region than some decent pipes but at a fraction of the costs for all mentioned parts.

No problem with his guy,I send you a YPVS unit out of order,he have repair and modified .
From one year he work fine.

+1 for Nick.
I use a modded one repaired by him some 10 years ago and very happy with it.
He also makes some nice leak test kits very useful ( not to say mandatory ).

Blimey - that's awesome!

Trouble is nowadays finding YPVS parts (x4)!!

"Making 654cc, wondering "
I'm wondering if its character remains essentially the same, just more .... attitude.
Or if its become more of a torquer.
125 done to 144 dirt bikes seem to be the former, but even my beta 200, bore and stroke altered, is still fairly zippy.
Custom pipes or ?
