I didn't think my opinion meant that much! Wink

I just find it amusing that every now and again someone wants to try and find something to fix on an NSR! There are plenty of 2-stroke failures common to all the 250's, and without doubt this is the highest concentration of NSR owners in one place outside of Japan so it can appear there's a lot of piston/ring/barrel issues at times, but they usually stem from previous uninformed and incompetent ownership (often in Japan!) or from piss-poor "race" setup -- the NSR is unquestionably extremely reliable, probably the most reliable, as far as 2-stroke race-reps go!

The electrical and electronic components are superb, as they are on ALL the modern 90's 250's, and in reality ALL makes and models since the early 90's! Even the MC16 stuff is good, and I personally put the majority of their failures down now to vibration, humidity, and the fact the newest '16 is now 21 years old! How many 21 year old TV's and VCR's are there out there still working that hard under those sorts of conditions?!

PGM's predominantly die when the RC Valves cannot rotate freely due to poor maintenance... I will put 50p on it! Smile

There's nothing to stop you guys discussing it still, but what will the outcome be? Is someone going to manufacture a tiny M-max sized box which will plug in-line between the harness and RC servo that will "pop" before the PGM if it detects a current draw out of range? Are the black boxes going to be mass produced and marketed specifically for each model, and sold at a price that makes it appealing to everyone to go to the trouble of buying and fitting it? The opening post hints at the fact that a solution could be worked on that will benefit the WHOLE NSR community.

Personally I just can't see the point!

I bet if you could magically "see" all the dead PGM's and the reason for their failures, the number that died because of a "feedback signal/resistance" issue is virtually non existent! Confused
