Morning Foccers
Just in the middle of another carb pull & strip/clean for shit running.
Done the usual Ivanising process yrs ago, Pipercross filter was recommended, personally I'm on the fence about its filtering ability.
This is the 3rd time in as many yrs that the old girl has developed pilot jet like symptoms & running like a bag a spanners in the low rpm range.
Went out for a blast the other day, bike felt to not be running as smooth as normal, come to think of it, it's felt a bit shitty low down in the low rpm range on the last couple of rides.
This last ride, proved to be showing a very shitty running motor low down, I even pulled into an Adsa car park half thinking I was due for a break down of sorts, a bit of the usual swearing ensued, checked the obvious, all plugs leads seated & tight.
So ride got cut short & a detour back home, low rpm running was by this time much worse.
I had all the classic symptoms of blocked pilot jets.
So yesdi I pulled the carbs, I was a bit shocked with the the state of em internally, loads of crap gummed up around brass throttle butterflies & around the pilot holes, pilot jets weren't blocked, which I found odd, I expected to find em choked solid with crap, but no, fairly clean, I could see thru em, poked em thru with my usual method (guitar string) left em soaking in EGR cleaner over night along with all the other jets.
Float valve seats are still good, just needed a bit of a wash in brake cleaner & washed out filter basket, O-rings still supple.
Only way I could shift the accumulated crap within the carb body was copious amounts of scrubbing with old toothbrushes & Holts EGR cleaner, it's awesome stuff but very potent, it likes to eat most rubber products so be careful if you use it.
So wondering if anyone else is having poor filtering from Pipercross filters?
I'm gunna throw my OEM paper filter back in, it's still as new, not impressed one bit with these Pipercrap filters.
I've even bought the Pipercross cleaning kit & re-oil spray, but I've lost all confidence in these foam filters, first time I've used em & it'll be the last.
I've used mainly K&N filters (oiled) on most bikes in recent yrs, running a Sprint race filter in my VFR, virtually same deal as a K&N but seems a better made filter.
Thoughts?
