That filter does not look like it was changed last year.
....
New OEM filter is white and you can see light through it :lol

Wow. I have a note here from February this year saying the mechanic changed air filter. That's just crazy. Is he duping me? I thought he's a nice honest lad. I will have to pull out the receipt and double check. I really hope it was a mistake from my part.

Seeing bike has already done 70k+ miles, would a K&N air filter be kinda aspirational? Def not getting hiflow air filter based on the experiences here Big Grin

#

The said note I had somewhere (it's not much, but may be you guys get a laugh out of it, figures are in EURO not Sterling)

4 new spark plugs.
new oil and filter.
new air filter
new front brake lever
new rear break pads
new rear piston seals etc, piston & calipers serviced and reconditioned
33 bhp RESTRICTOR WASHERS taken out from the carb intake - FULL POWER NOW.
3 hours of labour x 50.
+ VAT brought it to 340.

Where in the Emerald Isle? I live near Cork City.

Would say that.
We had a great dry summer last year, three dry days in a row in July :lol

:'( Possibly! In my defense, I get it fully serviced every year and when the mechanic charged me for an air filter I assumed he had changed it. Last FULL (read expensive, €340 euro = £270) service was in February, just 5 months ago! Coming to that stage that I am spending more on the bike per year than the bike is worth... :lol

Re: Will not rev past 8k. - darrsi - 08-07-14

Had a similar scenario years ago when i was having work done on my bike and asked for the front calipers to be cleaned up while he had the bike.
I had them apart a few months later and they were in a right state, they couldn't have been touched at all.

And 70,000 miles out of a paper air filter :lol

In 1977 I was fleeced by a Motorcycle dealer in Dublin because I did not have Vacuum Gauges or the tool for adjusting the tappats on a GS550 Suzuki. I swore after that I would never darken the door of a dealer again other than to buy a bike or maybe spares. :finger

Two weeks later I bought both items in the USA and a friend who was on holidays in the USA brought them to Ireland when he was returning home. (I still have them).. A month later I bought a torque spanner and now own 3 of them. Smile

I have never left any of my bikes near a shop since, I even change and balance my own tyres.
I o help a friend who is a bike mechanic with electrics and electronics and recently he had a bike which the owner took out of the dealers because there were charging so much to sort out the lack of charging (no pun intended) on his bike. When he took the bike out and gave it to my friend, we discovered they had melted the ignition switch after fitting the wrong regulator to it and chopped the wiring loom to fit the wrong regulator. :wall

Invest is a few good quality tools and especially a good torque spanner in the range of 5 to 50 Nm 3/8 drive. (The 3 torque spanners I have range from 0 to 20Nm, 3/8 drive, 8 to 50Nm 3/8 drive and 20 to 150Nm 1/2 drive). At least as a beginner you will know bolts are tightened properly. There are many small bolts on bikes which are easily overtightened and stripped.

Re: Will not rev past 8k. - positron - 09-07-14

Absolutely. The best part of doing own maintenance is memories like that one right there.

I would really love to try and fix and learn in the process. Lack of time and initial investment stands in the way, but when if I add up how much I am paying to mechanic for simplest of things, it's a no-brainer. So far I've managed to change the downpipes, fix some minor cosmetic stuff and tighten the chain, but that's about it. I just don't have the right tools for the job as is, and you are right about sheering nuts and bolts, I've already butchered a few. Sad

Problem is many fold I guess - I have attention span of a gold fish. Secondly, I have no warm place to work on the bike when it turns cold, which is a problem as I commute year round (even when it snows). Frozen fingers against sharp cold edges = excruciating pain to my wussy Indian hands that's designed excel in 30+ degree C! I may have to fix up or upgrade my garden shed to accommodate a bike or two in near future. And My "tool set" so far is pitiful - just an Halfords ratchet set, couple of spanners, bunch of screw drivers and others odd bits and pieces. Oh and an Aldi (or was it lidl) torque wrench (28-210 nm) which I am yet to use... I have been looking for a torque wrench (spanner?) at the lower range like you suggested, but they are all €70+ range... but perhaps I do need to spend that much for quality stuff. Any particular recommendations?

PS: Order placed for K&N air filter with wemoto yesterday.

Hmm, somehow I thought these were more expensive.. This looks affordable..

Re: Will not rev past 8k. - Buzz - 09-07-14

I, and a few others on here, own this one, £25 reduced from £65. 10-80 Nm and it's pretty accurate, at the lower end you need to slightly adjust it according to this scale (reading=real), useful if you're doing the exhaust studs up to 10 Nm and don't want to snap anything! -

[color=rgb(51, 51, 51)]3Nm=5Nm, 8Nm=10Nm, 9Nm=10.9Nm, 11Nm=12.5Nm, 13Nm=13.5Nm, 15Nm=14.9Nm, 20Nm=19.9Nm.[/color]

Re: Will not rev past 8k. - unfazed - 09-07-14

I prefer to go for a smaller range which is why I have 3. Much easier to set 10 on a scale of 0 to 20 than set it on a scale of 5 to 100.
Generally the shorter scales are more accurate. I have Norbars which have an accuracy of + or -3/%.

Most important rules of torque wrenches is

1.Trust them when they click, it is tight enough, do not go the extra bit to be sure
2. Wind them back to the stop when finished using them.
3. Do not use them for undoing bolts or nuts
4. Do not drop them of throw them around.

Thank you, I like that one. So based on the scale, you can't get to any of the sub 10.9Nm settings with that Draper? Is that okay with motorbikes in general and perhaps pedal bikes in future?

And I wonder how does this Teng 5-25 nm 1/4 compare (especially since I already have a 28-200 Aldi one):

Re: Will not rev past 8k. - unfazed - 10-07-14

Ideal if you have 1/4 drive sockets.
Most used 1/4 drive sockets are 8 10 and 12mm and a 150mm 1/4 drive plus extension bar

Re: Will not rev past 8k. - positron - 12-07-14

Thanks my this is my current socket set: http://www.halfords.ie/motoring/garage-equipment/socket-sets/phaze-50-piece-socket-set

* 9 x 1/4" Drive 6pt sockets: 4, 5, 6, 7, 8, 9, 10, 11, 12mm

The mix of fractions wrecks my head - I much prefer decimals, in fact back in school I didn't really get into fractions until I was 12 and I was tasked to help a bunch of juniors to learn fractions. Strong mental block! Smile

While I am still waiting for wemoto to deliver K&N air fliter, I dug out my last full service receipt dated 7th Feb 2014, and it says:

Spark plug - 4 x 10.13 - €40.52
Oil - 2.60 x 8.37 - €21.76
Oil filter - €9.69
Air filter - €16.70
Rear break pads - €25.11
Rear caliper seal kit - €14.40
Brake fluid - €3.96
Front brake lever - 17.62 (it was broken when a junkie kicked my bike over outside my office)

And you guys reckon that filter is older than 6 months? Jesus christ, may be I should check my spark plugs, brake pads etc too now Sad

That air filter is probably older than 6 years more like.

Get rid of the fraction as you call them, correct name is imperial and are no use, unless you are fixing old English motorbikes. All nuts and bolts on the fazer are metric.
Definitely much older then six months unless you were riding around in a working coal mine :lol

Re: Will not rev past 8k. - positron - 16-07-14

Okay that's a lot of confirmation for the age of air filter. So my mechanic either made an honest mistake, or he was shafting me. I need to establish which because otherwise I should look to replace spark plugs, brake pads etc too asap. Not looking forward to speaking to the mechanic again to be honest.

On the plus side, K&N filter arrived yesterday and I installed it last night. Obligatory Old vs New photo.

[Image: IMG_20140715_200944.jpg]

This morning on my usual route to work (68 kms, plenty of time to assess everything), bike didn't feel any different at first, but within about 4-5 kms and it was obviously revving free'r and felt better around 4-6k rpm range. There wasn't any significant increase in power that I could feel at that range to be honest, it just felt better. Further up 6-8 felt great, and bike was happy to sing along to 8-11k as well which is as far as I could take it on the motorway today. The The free'ness in 5-8k range is brilliant because that's where I am most at.

Thank you again to everyone for helping me sort this particular issue, but even more importantly, for getting me back into DIY mode.

I am not out of the woods yet though. Bike now cuts out when warm - for instance at the end of my commute to work today, if I pull the clutch in coasting down a hill, it would just die. Coming to traffic light, pull cluch in, it would die. I have to constantly keep a tiny bit of acceleration to keep the engine running. When cold, the idle is ridiculously low - it's like 500 rpm or less even. I can't seem adjust it as the idle adjusting thingee on the right side under the tank isn't turning. Well it's turning, but I think it's the entire cable thing behind it that is turning. Perhaps I should try dousing it on WD40 etc for a day or two and it might free up? Is there anything else that could cause it to die so easily when engine is really warm?

Re: Will not rev past 8k. - andybesy - 16-07-14

From memory I'm pretty sure the idle idle adjuster is on the left side?

EDIT: actually maybe you're right I forgot now. I do my choke manually on left side so I may be confusing with that.

Does the idle speed adjust when you adjust the control?

Certainly a bit of WD40 or similar on the carb mechanisms once in a while can help them remain free. I snapped my choke cable due to a seized mechanism on the carb but WD40 released it no problem.

Just to give you an indication what you're looking for, my bike is set to idle at 1200 - 1300 when fully warmed up, with translates in to an idle of about 1,000 when the engine is cold (normal weather). If it's a very cold day then it might be lower and need a bit of choke.

Re: Will not rev past 8k. - Buzz - 16-07-14

Hey fella,

I remembered that another user (Macca4786) had a similar problem with their Idle Adjuster doing nothing, turned out it had completely unscrewed from the carbs. He managed to screw it back in without taking the carbs off, much to everyone's surprise!
