Sick Suzi

[Disco Dan]

Oky-dokey...

Caps seem fine - tested them. Leads are borderline ok.. so bought new ones.
One lead... checked inside and one of the contact needles has begun to rust...

So now, clean out the coil contacts. Fit new leads and fit the old caps back on.

...back to the shop for more cable methinks... what a kurfufle..

anyone got any tips for getting the new leads onto the caps? they screw on.. but are hard to get started.

UPDATE:

Well, all new leads installed. Apparently, I wasnt meant to pull the leads out the coils.. woops. They are a sealed unit and are bought as one item according to Suzuki. Well if it aint broke dont fix it yeah! Oh and they wanted $49 for EACH CAP. Told em their dreamin.

Everything shiny and new... back from a quick test ride. Same thing. damit.

Not quite as bad, but still very sluggish and hesitates over 8000rpm.

What next? prob coils, will have to look up how to test them. If coils test out ok, then the carbs are coming off...

If they have a screw on cap they're capable of being disassembled i.e. the leads aren't moulded into the coil, so they're either talking crap or they're only able to be purchased complete.

Considering how little you actually did to it (oil & filter, clean & re-oil the air filter, spark plugs and a bit of carb cleaner down the carbs - presumably running?) there's not that much it can be. I'm still going with suppressor caps - probably poor contact with the HT leads or perhaps at the coil end.

Does it do it only under load at 8000rpm or can you get past that 'barrier' on light throttle? What about high load low rpm (like 3/4 throttle @ 2500rpm)?

You mention water a bit throughout the thread.
Are you sure you have none in your tank?

It may sound silly but I have had similar issues on my old 1100 after getting a small amount of water in the tank refuelling in the rain.

If you rev it up and back off suddenly in neutral what does it do?
And the same thing in a gear (not first or second)?

Any decent auto electric shop will be able to buy NGK caps from Darbi's or wherever. Don't over oil your filter. If oil drips off of it or pools, you've way over oiled it.

Dude - you SURE it's not the K&N filter? Remove it from the bike... take it for a test ride. If no difference you can rule it out.

If the problem disappears I'd say you've over oiled it - it's and choking the bike. The could come up at >8,000rpm because that's when you give it a handful and everything opens up - except the airflow which you could have choked off a bit (alting the fuel mix etc).

That's be my first port of call. 2nd would be leads etc which you're obviously working on.

If you do pull the K&N filters best to make sure you pull all of them off.

I dont think its water in the tank... I filled up just after it started happening. Should I put a capful of meths in the tank just in case?

I have re-oiled the filter, and im pretty sure I did not put too much on. I will take it off and try it that way to check thought... ( I dont remember it being red when I took it out the first time to clean it though... just a pale white with black speckles...so maybe it did not have oil on it?)

The leads have a weird double clip on each coil, one of the contacts was rusty which i cleaned as best as I could.

I went to repco to enquire about new caps - they could not find them in their parts list. Henderson Mcycles, quoted me $48 each cap.

The trouble is even if only one of the caps is faulty, there is now way for me to test each one and find out. I have to replace the lot?

Thanks for your advice folks!!

you were right MDU, twas the air filter! Removed it and went up the road... ...cleaned all the oil off and put it back in.... ...then removed the restrictor baffle... far out... goes like the clappers...

Ok so shes all better now. After taking the oil off the air filter and running it dry, it seems she was starved of air at high rpm. Tried out the redline in each gear this morning and she still wants more air than can be delivered. Fine under high load upto 10500rpm (redlines at 12) then there is a slight hesitation again although not as bad as before. She still wants more air!

[Disco Dan]

Well it seems my suzi is no longer sick... still dont know what was causing all the problems though.... really weird...

She was still gasping at high RPM, the air filter fiasco just moved the symptoms further up the rev range...

..however, on wednesday I gave her twist, hit 8000rpm and peow... she took off... "WTF? the power band is back?" ...took her to red line in second and third... shes not gasping? TIS FIXED ! ! ! No idea what was wrong... it just did not work... now it does... !! joy! off to play with my powerband again!!! yahoo!

If the original problem was your air cleaner your carbs would have been full of impurities such as filter oil.
Not necessarily the evil but probable.

I think it was too much *bike love*
