Lost power over 3,500 RPM...but only when hot. That's weird.

[SA14]

Yeah, nah might give the $50 million dollar Suzuki fuel pump a bit of a miss and paying $90 for a small piece of plastic would probably make me pass out from mugness.

Do me a favour and buy the $700 one but please give me first option to buy the one you're replacing. When the new one blocks up can we do the same deal or will you have realised that a simple 4mm hole and $40 filter was a good idea. BTW, I can do you as many tea bag filters as you like for a bargain $40 each.

Let me see if I speak Snapey...do the external filter mod and clean the tea bag. How did I do?

Plus, it might be something else. I haven't started spinning spanners yet. I want to have a look at the plugs and see if any have come loose. Not sure how I can check the leads without a running oscilloscope or the coil packs but I'll do a visual inspection and then go for another ride until I can get it to repeat the problem then I'll switch off the ATRE and see if that helps and if not I'll head home and do a pump volume test and go from there. It still seems odd that the problem only arises when the big got hot.

Fit whatever pump you choose, its not the problem. Most, all high pressure pumps can supply enough at 43 psi. Its the stupid filter design that ruins it. Not sure i understand why you blokes dont get it. At least Snapey, Rick C. Northern from memory, understand how much better with external. Simple, easy and cheap mod. GSX 1400 loves it. GSXR guys talk of gaining 2k revs. Even V Strom blokes are happy. Just my opinion.

I don't know about you Grog but I'm done bashing my head against the wall.

No, I'm hearing ya bro. It's not that I don't "get it". I'm just asking questions and gathering thoughts. Obviously a bit hesitant to be drilling holes into the pump given it has to be an exactly correct angle and all but I've read the thread about it and will read it again. I like mods, got no problem and I was only mentioning the price of the Suzuki fuel pump for laughs. I'll try cleaning and make sure it's nothing else before I start drilling into my fuel pump though. Extra 2,000 rpm sounds nice but doubt I'll need it although I know that's not the real reason to do this. For all I know the bike's never had full power. When I rode @Throttle 's bike it felt far more powerful than mine - instantly and I only just rode it a few hundred meters around the block. He said it was the exhaust system but what if mine's been suffering low power from a failing pump? It'd be great to get full power though I've been pretty happy with it until now. Seemed to pull very hard and want to take off without me.

I'm not sure I understand all the sudden anger here. I have an obvious problem with the bike and was just asking questions. I'm sorry (not sorry) I've upset everyone.  JFC don't worry about it. I'll figure it out myself or take it to a mechanic. Thank you everyone for your input and I'm sorry for wasting everyone's time.

I never rev mine over 6.

Don't worry about it Baz, they are all old a cranky.

Snapey, think the wall fell down. Its so documented every Suzuki forum. Why waste your time testing, cure is written. Maybe a few other random things but you need good fuel. Drives me insane, blame everything else but filter is clogged. Seen sim on cars, my work truck, it just pig rooted, wouldnt rev, fuel filter the cause. Heat makes it worse, hot days. low fuel supply gets worse in heat. Rang the Proflow blokes today, O ring a bit dodgy, advice was just find one that fits, agree? Since external, my bike revs to whatever, i actually think the reports of power dropping at 7k revs, now 8k revs. Not sure im correct but sure seems so.

@SA14  please don't get me wrong but I think there is no anger, it's just that you ask question for every detail and it's hard to explain it in text messages. It only takes 30mins to take apart your fuelt tank, pump and HP filter and then you will see every detail people are talking about and you will be able to understand at least 80% questions that are bothering you (for example where to drill for external filter mod at what angle...). Try it, you can do it!! And thankfully there are many pics and articles on internet and here we are to help you!

And don't forget to take photos and post them, photo say more than 1000 words! 
No hard feelings!

Glad you're getting it sorted @SA14 don't take any offence. 

Well said @mlivkovich

Highly recommend these. I just fitted one to my 750 SRAD a few weeks ago and it's perfect. Fast delivery from the USA to U.K. as well. Did get stung for £10 import duty though but still cheaper than anything I could get in the U.K. and great quality.

Just looking at the forum and has been the case for a little while now it's so quiet. I realised that even Baz (SA14) has totally disappeared which is strange as he was prolific on here and a lot of his posts were pretty interesting. So I looked up his last post and it seems he took offence to some of the replies which reading back aren't aimed at him personally. You can always read something into a post that's not here. Come back Baz I miss your posts!

[grog]

Phil, thats happened a few times over the years. Ask questions, we try to help, they take it wrong way. Just how it is. So many prolific, genuinely incredible with answers, posters just disappear. They just move on i guess.
