What Did You Do to Your Bike Today ?

[AndyAndyAndy]

At Monday I punctured rear inner tube. Bought new one and fixed it. Yesterday I punctured front inner tube! Again I bought new one. And while struggling to put tire back on I ripped a hole in inner tube. So I just went back and bought third inner tube.

 

They are starting to give me a funny look in a local moto shop. 3 days/3 inner tubes. ???? If I rip a hole in this one or puncture it again today, I'm just driving to some other village to buy it.

Did you use the duct tape trick ?

Insert tube in tire. At 4 equidistant spots around the tire wrap duct tape tightly, so the beads touch together.

12 - 3 - 6 - 9 o'clock

Tire falls right on rim. Rotate until tube filler lines up with hole, insert and tighten nuts.

Cut duct tape, remove, Inflate tire.

Done

Me too. Colortune is worth the money. 

Hope so the plugs I have are genuine but not copper core so judging on exhaust behavior and sound is not that precise.

I had one of those back in the day before the introduction of the periscope thingy.  You just looked down the centre.

Yeah I think I will need a periscope my plugs are very low within the cam head cover.

9000 rpm is that a small cc bike all are you a wanna be nutter. ????????

What's important is to check the carbs first and fix any possible damage. If a diaphragm has a little hole you can check it this way:

 

( Only for CV carbs)

 

Take the airbox/filter off that you can see the slides. Then blow some air from your lungs into the breathers and see if they open. 

 

All diaphragms should open as easily as the best one does. If they don't sit in the grunge, it's similar to one with a hole in it.

 

  There's an interesting video of a guy who figured that out, something that is not in any textbooks for mechanics.

 

 Once you know that your slides fully open at the same time, you're good to go for synchronisation of them.

 

But you also need to know when your floats stop letting fuel in. If they close too early, or too late, you'll never have a good running engine. 

 

There's the "clear tube method" where you can easily see when your float closes. 

 

Here's the easiest explanation on how to do that.

 

 

    Once that's done, you still have to check your air/fuel mixture, or sometimes also called pilot screw.

 

       Turning it in makes it leaner, turning it out makes it richer.

At some carbs, one fourth of a turn makes a big difference. 

 

Mark your tool you're using to be able to see how many turns you did.

 

If you use the right type of spark plugs you should be good to go.

 

But be aware that you do not need any fancy Iridium plugs that could be copied by China. 

 

Ordinary plugs are much better to read and the color should be light brown to caramel.

 

Here are my spark plugs after a few thousand km's.

 

The color of the plugs tell you all what's going on in your combustion chamber.  

 

( I've overhauled the carbs twice and was lucky to see the faulty parts)

I never let my bike get into the red zone, You don't have to be a mechanic to understand why not.

 

  If the bike isn't riding, 9,000 RPM's are doing more damage to it than anything else.

 

But I also know that Thai mechanics do that until the piston comes out of the exhaust.

Read all about it before you do it. The periscope is there for a reason.

I just found out that they even have a machine to change tires in Sisaket.

 

  Not too long ago, I took my tire to Ubon R. to get them balanced. Technical Thai sucks. Especially when they don't know shi_e about it. 

 

    Let them do the job and get the tire(s) balanced properly.

Get back to you that all can say at this moment is there isn't anything I don't know about CBR900RR bikes. ????

Nor do I that's why there's a rev limiter on most bikes, when I raced the bike I have now in uk I was always hitting the limit the trick was to change at the right speed for the gear you were in which was something you learnt.

9000 rpm is nowt for most bikes that's why I asked OP what bike it was, it would be s crazy thing to do on my bike in Top Gear in Bkk.

Yeah thanks  and very helpful for guy doing there own DIY stuff on their older type bikes but myself answer your long post as altered.

 

1. I have already posted on this thread, the carbs have been totally dismantle and clean and checked.

2. They are CV carbs and I like em.

3. The diaphragms are all in good order no holes.

4. Yeah know about that technic for years thanks.

5. Mine are factory synchronized set.

6. I have genuine NGK Iridium plugs.

7. Not these plugs it don't.

8. As 1.

made sure the tank was full.

It was before, and after 30 km below 50%. Maybe I need to re-check the carb as that was about 7 liters gone. More then my old Benz.

It is now full again without pain with the current price.

Only 18b/liter , big difference with years ago back at home petrol 91 nearing the 2 euro/liter. (75thb/l)

Sounds like a load of rubbish to me, or maybe you have a serious fuel leak, so come on what's the bike.?

It sounds rubbish to me too. I think it is a combination of; bad carb adjustment, non-lineair fuel gauge meter, not horizontal position when filling with gas and perhaps a leak but then I would have smelled it.

 

The bike? Not the one at the right side in the picture.

Good thread this started by lets not forget by "canthai55" I was disappointed to see to see Guzzi leave.

I'm here in Sukhothai with 14 days of isolation, OK, so whaddya I am ganna do strip bike down to do the "colortune" check.

Involves taking the tank off and rigging up a fuel line for my bike.

Needed to do that anyway because my proper fuel line has arrived and I wanted to replace it, the clear plastic type fuel tubing has been OK but I have my doubts.

I shall tidy wiring too and hard wire where I can to get rid of old joint connections.

Front brakes still need bleeding more, got them reasonable after fitting new braided lines but need help really to get them solid like the back brake.

Made my homemade tool to clean suspension seals but will replace them if it don't work.

When I'm done will be red-lining on the highway near me.

[katana]

Changed the engine oil and oil filter.

Mucky job, but luckily only required once a year.

[Damrongsak]

I parked my bike and went jogging instead.

Re-post #798 before ganna do that stuff wanted to empty fuel tank  more, so off to highway, I know a high speed nice and smooth bit, but what happened when one of those long arm tractor thingys pulls out,  he wants 2 lanes ???? he has no idea of someone coming towards him at 255 kph towards him, it's just a single light a motorbike light.

No problem but parking bike up now and do my improvements.

Happy days. ????

[Isaanbiker]

I've changed my oil. Checked on my spark plugs, adjusted the gap to 0.75, they're lovely and have a healthy caramel color on both pots.

 

I'll now adjust my headlight an additional high beamer and hope for some more rain. 

 

  

[Isaanbiker]

I've pulled my rear baffles and it was a pain in the butt.

 

I had ordered a hole saw with a 38 diameter. Unfortunately, did the other two ordered ones not arrive yet so I started with one.

 

   The freaking Chinese part the lost some teeth when it came on a welding. ( They are welded in) But then I saw another baffle deep inside. 

 

    The joke is that it's not louder as it was before with the holes drilled in the outer mufflers. 

 

Please excuse my foul language in the video. I've wasted two days for almost nothing!

Mate, ride safe,. i can't believe that you're doing such speeds in a Land full of idiots. 

[papa al]

Yup those idiot farmers on their tractors should keep better eye out for farang doing 255 on bike.

Stupid monkeys.

No worries sportsbike riders do this, an wide open straight highway and  deserted except for farmers and could pick him up a long way ahead, hit 270 kph after passing him hoping for more when the carbs are color-tuned then I will be just happy with the acceleration, top speed not important tuning is but I do luv speed, that why I got the bike.

[Kwasaki]

Stabilize tachometer needle and as I thought bad earth, when for test ride and found as I knew but just wanted to check 75 - 80 mph 5000 rpm. So to Colour-tuning now.

 Hang on getting back 25 year old radio leaking,  fixed it once but these old metal rusting rads of the day no good,  ordering a new Aluminum one. ????

[Kwasaki]

Can't go far so well another thing sorted, sportsbikes can really be a pain to get to something simple. ????
