Afternoon all.
Thought I might just mention that I have eventually got around to removing the PAIRS on my 2003 60,000 miler, that i have had from new.
I was getting a slightly jerky motion at about 30 mph which according to the forum could be attributed to the PAIRS.
So I obtained a kit which include the two alloy plates, new bolts and the two blanking bungs needed. The longest part of the job is popping the tank off! I thought that the new plates had a quite a thin mating surface, so elected to re-fit the reed valve holders after removing the reed valves themselves.
I have been very pleased with the result. The engine is much smoother especially at the low to mid range (ie: 30 mph in 2 or 3rd gear). So I'm well pleased.
Of course this won't come as a surprise to those orgsters who have already done the mod. :grin:
Keep safe
Chip.
The symptoms sound just like mine. Feels like a very subtle misfire and makes riding slowly around town a bit tiring.
Could you provide a link for the kit?

@numbskull If you read the PAIRS removal thread, there are 3-4 links for kits throughout the thread itself, choose which one you prefer (thanks
@Notty I've added the link above to the end of the thread)

A very interesting read, thanks for the links on previous threads. I have an aftermarket 4/2 and can say in all honesty, the only time I have noticed backfiring and popping was while fanging it at very high altitude, higher than anything we have in Australia :mwink:
I wouldn't mind making the mod anyway.

Hi Numbskull. Apologies for a late reply. I've been away for a few days. I found this on e-bay. Very quick response and good comms with updates on the delivery. Arrived as promised.

Hope this helps, if you haven't sorted it already.

Reading today, GSXR people use PAIRS as a pump to create negative vacuum in crank case. Worth 2 bhp they say. Never heard of b4 today, have a google. Not something i want but a good read/can of worms.

Run a GSXR without any crankcase vacuum, and oil pisses out from cam cover, and anywhere that has a poor seal ............ ask me how I know. OK don't ask, you've already worked it out.
Block off crank breather instead of PAIRS hose, see how much smoke a 14 can make. No idea how i know that. :laugh:
