Sick Suzi

**Disco Dan** · 31st March 2007, 13:31

Did a service on Suzi yesterday, and she has not been behaving since. Changed the oil and filter, replaced the spark plugs (correct gaps) as well as pulling the K&N filter out and cleaning it and re-oiling it. While I had the filter out I sprayed a bit of carb cleaner into each port, and gave everything a little rev before putting things back.

Now when I nail the throttle, it seems to hesitate and jerk a little. It feels starved of petrol or air at high revs. Around town it's fine, its only when I jump on the mway and start using the higher revs it starts choking.

Any suggestions?

Should I reset the computer?

Thanks in advance folks.

Over- oiled the air filter?

Blocked main jets. Simple to fix but you'll need a screw. Driver?

That is a posibility? I have never had a K&N filter before, and just sort of 'guessed' gave it a good spray until the whole thing was red like it said on the bottle. I may pull it out (which means taking the tank off, the battery out and removing a large metal bracket that has about 6 bolts on it) cover the hole with a bit of cheese cloth and take her for a quick blat.

Everything looked hunky-dorey before and clean as a wistle after the clean up? I guess I may have 'dislodged' a bit of muck and caused a blockage??

Im not familiar with these carbs, they are a little more complicated than the SU Carbs im used to working on in minis!

Not really. Disconnect the throttle cable, pull the carbs off as a bank, turn em upside down, remove the float bowls, pull the slides out, grab an airgun and blow the fuck outta the jets. Reassemble and rev tune

I am concerned however that the battery water was about 2-3cm below the "low" mark, after only 3 weeks from being topped up before.

I smeared vaseline on all connectors and gave everything a good coating of CRC as part of the service. I did notice a little water in each spark plug chamber, again a skirt of light oil and a rag sorted that.

At the moment, everything seems to point to the air cleaner. The only other thing would be the spark plug cap on piston 4 popped off the wire (had been repaired before) and there was some green corossion inside. Cleaned up and re-attached and seemed to work fine.

Just clean using air? i gather rev tune to mean, idle?

Before you shag around with the carbs, put the old plugs back in and eliminate that first.

they are a pain to get out... have to remove part of the frame and need a weird size socket to get the smeggers out...

The repaired HT cap may be the culprit, as I just pushed it back onto the wire and did not re seal it with silcone... goint to pull tank off (again) and tape it up and see if that makes a difference.

Tape on the outside is unlikey to make any difference if that is the culprit.

Just pulled the tank off, cut the HT lead off and re-attached to the cap.

Noticed the timing chain needs adjustment "can hear it out just a tad".

....going for a quick blat up the Mway now

Personally, I would check them while you are half the way there.....
or
you could put it all back together and it not be fixed, then you should definitely eliminate the plugs !
which will require you to remove all the parts you just R & R'd.

And who do you think you are Paturoa, thinking that duct tape won't fix everything????

LOL
