The "Today I did something to my bike" thread

Pedro K

Friend of mine and club members GT550. Engine was put of another GT he had which was stolen and recovered in a bad way.

Engine has essentially been rebuilt and he got it started the other night. Great. But it's only firing on two. On Sunday we took the carbs apart and cleaned them all. Still only two.

Any ideas?

Is it sparking on all four cylinders?

Yep. All four plugs are sparking.

Is there compression in all four cylinders?

Not sure about that. Will have to check...

Plug leads on the correct cylinders ?

If the coils were connected (1,2) (3,4) instead of (1,4) (2,3) you'd get that

Most inline fours have two coils and a wasted spark system*, so it doesn't matter which specific lead goes to which cylinder, as the coils spark plugs fire in pairs. One coil should go to the two end cylinders and the other to the middle cylinders, so the only variable is which coil is the 'middle' coil and which coil is the 'end' coil, get that wrong and the bike won't fire at all.

Often the original HT leads will be cut to the exact length and only fit one way around anyway. If they've been replaced (and at that age it's likely) then they're probably all the same length, so it'll be possible to get it wrong

* the spark plug in each cylinder fires at the top of the compression stroke and the top of the exhaust stroke, the second spark doesn't do anything and is 'wasted' but it means two coils can feed 4 cylinders with no need for a distributor like cars used to have.
Most cars now have individual coils at the top of each spark plug, my bike does too but as it's a 120° triple it has to have three coils anyway.

New front calipers fitted and old lines rerouted. Well happy with the result! Took frickin ages to bleed em though, lot of head scratching... couldn't get a good vacuum on the master cylinder bleed nipple, so i eventually resorted to a little bit of pfte tape (don't have or know what sealing grease is).
And then had to reverse bleed the master cylinder (as in force fluid into the nipple) before I could get any movement of the reservoir level- ugh, sorted now though, just took an hour or two longer then it should!

oblig before pic- calipers are in a very sorry state and let the bike down big time. More annodising missing then present! They look even worse in person:



After pic- lines rerouted and secured a bit neater. Cbr monoblocs fitted with 5mm spacers:

Finally got around to replacing the speedo drive. I now have a working speedometer.

Are you talking about rsv mille? If so i believe the stock tail is not as big, or at least mine wasnt, it was like a triandle light weight black metal thing. Actualy really pretty. Btw well done there. A pic of full bike would make me recover some great memories if u could tho...

Here you go, matey

Here's what I've been at:rolleyes:

News flash: Milles don't have a kill switch on their side stand

both front and rears where in a bad way on mine unfort. Under recommendation I tried Hammerite on the rear, but it didnt last more then a few months sadly - looked well initially mind! Kinda knew it mightnt, so rear was just a tester. Brake fluid just too much for it and started some bubbling around the bleed nipple was ordering bits from ebay, so just got a replacement thrown in for next to nout (only little bit more then what I initially paid for the paint iirc!)





doesnt look so good now however! dont know of anyone annodising in ireland unfort, but powdercoat supposed to be very good idea

Found a company in UK that will do a full reburb, seals clean etc and powdercoat for well below the price of second hand calipers, so just need to save up now:D

They do have the kill switch but its one of the common fualts, stand switch, reach brake sticking, clutch slave cylinder amd many more.

Well its a beast but not for daily driving.

Oil and filter changed. Made a half ass attempt at cleaning the exhaust headers, need steel wool to do it properly so I will finish it off tomorrow. Checked the front sprocket, its fine but I do need a new chain so might as well get the sprockets changed as well while I'm at it.

I will send you a link for the ones I got Blue excellant and very good price from ebay. BTW, get some AUTOSOL on the headers and they come up like new.

If they're not too far gone autosol all the way alright- otherwise you just get nice shiny smooth rust :P had to use some 160 (I think) grit sandpaper to take the worst off a set I did last year

I was using autosol alright, great stuff. They are not rusted, just havent been properly cleaned in a while. I should be able to get them spotless once I get the wire wool.

Wonda - going for OEM chain, seems to last allot longer than anything thats out there.

Embarrassing accident today at, er, 0kph. Stopped on a quiet road, for a rest and to check phone. Sitting on the bike, on the sidestand, with my helmet on one of the mirrors. Somehow managed to keel over to the right. Broken brake lever, broken vizor, helmet which really shouldn't be used again, couple of layers of skin off one finger, some bruising on another, slightly sore shoulder. Not sure if happy or sad that it wasn't caught on video ( though at the time, I was glad no one was looking).

Been a while since I had to lift a bike off the ground. Thankfully that bit went fine.

Official started operation "get rid of annoying front brake noise". Phase 1 was cleaning the ridiculously stuck bobbins' . And once my back heals it'll be brake calipers tomorrow. After the GAA matches of course

Today I stuck a new chrome Simonini Sports exhaust onto my LML Star 125cc. It went on easily enough and then I up-jetted the Delorto carb to run a 100 main jet (was 94 as standard). The scooter now pulls great and further through all the gears and I hit 55mph on a short test run (and there's lots more in her). Only thing is now its a lot noisier than the original exhaust, still Loud Pipes Save Lives!!

I also investigated the high revving at tick over on my Vespa PX200. I've had this problem now since I bought the bike in 2010 and have decided to tackle it for good. I changed the oil pump cap for a new one (thanks to Ebay Israel, a cheap original Piaggio part) The carb slide ain't returning fully so the bike is reving higher at tick over and using a lot more petrol. The new cap didn't solve the problem!! I reckon that the slide arm is slightly bent. I will be popping over to Carl Perkins (the 2T wizard) in Inchicore, during the week to get a new slide arm and try fix it for good...
