Who sells NSR PGMIIIs?

**sharp2183** · 27th May 2011, 15:41

Does anyone in New Zealand sell or repair these things? Have a likely blown transistor caused by sticky power valves and need it either replaced or repaired. Does anyone specialise in this kind of thing?

Anybody with a soldering iron could replace it. If you're in Christchurch I would recommend somebody like Elite Auto Electrics who've got a reputation for doing this sort of work (replacing components on sealed ECUs etc).

Seriously though, it's a FET rated at 5 amps, and the part numbers are available on NSR World, anybody could do it for you. Hell, maybe even you!

/edit: BTW, the PGM is typical Honda Nazi rubbish, replace it with an Ignitech if worst comes to worse.

It's funny thats EXACTLY where the bike is at the moment. I'm getting them to make sure that it is the PGM causing the issues. So you reckon that they should just be able to open up and solder on new transistors? Probably something I could do but I'm not sure I'd trust myself not to mess it up.

If it is the PGM, then I assume I should have the power valve/servo freed up before I get the PGM fixed? Otherwise I could just happen again right?

At Honda?

Don't be too hard on the poor Honda mechanics... they're a JDM bike so they don't even have English workshop manuals to use... the Nazi bit is just in relation to the Honda mindset.

I would give it to an auto electrician like the one I mentioned in your other thread. If the bike is in Christchurch I might be able to help more.

Yes definitely find out what killed it... the power valves aren't hard to fix, easiest to take the barrels off, and whilst you're there do a top end. Cheap insurance, peak power, win win.

Nope I meant Elite Auto. Took it there this arvo to get them to locate the source of the problem. But sounds like I should get them to fix the PGM if they can.

The bike is indeed in Christchurch, so if theres any knowledge you feel like offering then I would gladly accept it. I did buy this bike as a learning experience after all!

Ok, if you can get the PGM3 for me, I can find an MC21 to test it in.

The guy who owns it (the NSR) has a pretty good understanding of what's inside the motor, might be worth spending an hour with him having a natter.

Elite Auto I would trust to be able to replace those FETs for you.

Oh and if you come back and find this thread is missing, have a look in the electrical section where you started your first thread... you might find that a moderator merges them, which not be initially apparent if you're not familiar with the layout of KB.

Sure mate I can do that. What do you reckon then, is it worth me paying Elite to find out what the problem is, or just put the PGM3 into the other NSR and see if that finds the problem? Then go back to Elite to fix it?

Yep I'll make sure I keep an eye on the merge if it happens. Thanks heaps for the info too, its amazing that a few posts on here give me as much info (or more) than a mechanic looking at the bike for an hour!

If Elite have the bike, I would talk to them first as that's good manners.

PM me to remind me; I will see if the service manual has procedures for diagnosing the servo, which will let them eliminate that. It might have a procedure for testing the PGM too. If not, we can try your PGM in a bike that has power valves that function correctly. If so, then I can email you the relevant pages which you can take to Elite.

As far as the power valves go, the first thing you need to check is that the cables are free and working correctly. They can rust out the inner, which makes it unwind, and then bind in the outer. If the cables are knackered, I can fix those for you.

If the cables are find, then you need to ensure that the valves themselves aren't sticking. If they are, it will probably be due to carbon build up on the valves themselves, but I assume that the activation shaft also has bushes in it, and I assume they can also seize and wear etc. If that is the case, I don't have an NSR250 barrel, but I do have an NSR150 barrel which is very similar (can be fitted to NSR250s when big boring them) that you could have a look at so you can see what's involved in repairing it.

Should the power valves need disassembly to clean, I would recommend at the very least checking the wear on the pistons and rings, and replacing them if they're worn... it's always easier to do it when you're in there with the barrels off anyway. I expect there is some detail in the manual for those also (I have an RGV, so I haven't studied the whole NSR manual in depth).

Ok well Elite will soon let me know if the lack of servo action is due to the PGM, so that will give a pretty good indication of where to go from there. If that is the case, it would be good to try it in the working NSR you speak of. Then Elite can have a go at fixing it.

I suspect that it is one of the two options in regards to the power valves that caused the problem in the first place. Common sense would dictate that I need to get those things sorted before I go anywhere. I'm quite new to 2strokes but at the very least I will get stuck in and clean out the power valves. NSR-World also has a rebuild section that discusses the strip and inspection of the top end so I can use that info to check the pistons etc and go about replacing if necessary.

Once I hear back from Elite then I'll send you a PM and see about checking the PGM in the other bike.

All good, let me know if you get stuck.

Print this and take it with you.

Just heard back from Elite, definately a bung PGM. So.. checking powervalve movement and the condition of the cables next. Then getting Elite to fix the PGM and we should be closer to being back in business...
