WOT runs

I Need The Same Help

I have those same mods, and once my bike is broken in, I will put them on. Except mine is a PC pipe, with the FMF silencer, removed snorkel with some holes int he airbox cover, Boyesen Pro series reeds, what is a good starting point for jetting? (someone told me to buy a 150, 152, and a 155 main, and a 42, and 45 pilot, with a stock needle.) Think I can get it jetted with these jets, and some help as to show me how to do it? :think: hmmmm

:eek: mines a 200, not a 220!

sorry bout that :think:

Im likin these new smiles feture! :yeehaw:

I had those same mod's before I added the RB Design's carb. I never could find enough real estate to keep the throttle pinned in 4th gear for 20 seconds. I would find the longest straight-away and run it through the gears, staying on the pipe hard. Then spin around quickly and do this four or five times then chop it. It worked. It told me I was still too rich. I ended up with a 40 pilot and 142 main but each bike is different.

Yes WOT means Wide Open Throttle!

Here read this from TECH TIPS: Checking the Main Jet– Warm up the engine and go for a short ride letting the engine comes up to its normal operating temperature. Install a brand new plug that's been properly gapped. With the new plug installed aggressively accelerate through the gears until you reach 4th or 5th gear. For best results you should accelerate up a slight up hill section to place additional load on the engine. Continue to run the engine at WOT for 20 to 30 seconds longer if there is not fear the engine is running lean. If you suspect the engine is running lean 15 to 20 seconds to give you an indication. At the end of your full throttle run simultaneously push the kill button, chop the throttle and pull in the clutch. This procedure is often refereed to as a " plug chop". It is important to perform a plug chop exactly as described. If you allow the engine to run or leave the throttle open for even a few seconds after the plug chop the plug reading will be invalid. Now remove the spark plug and carefully look at its color.


BTW, I've never been able to do a 20-30 sec plug chop, but I've done plenty in the 6-10 second range. I can still get a decent read, it's just not as dark a ring.

Ride it on the beach! (in the sand) You can run WOT in 6th for-about-ever. (then you can get a tow back to the rig when you port your piston...)


Anyway...
There is not a limiter on the US model. The kinda flat 'top' on the 220 is caused by intake restriction, port timing and such. No bike revs forever anyway. You may regard the slightly less than stellar upper band of the 220 to be a 'limiter', but it's not.

You can drag the brake a bit to create some drag if you have no riding terrain that will provide it. Probably the back brake (not the front), 'eh?

re: 'I have the same mods but they're not on but they're different'

Really?

I posted to this thread hoping only to once again be reckoned along with such effluvium and considered helpful.

YeeHAw!

There used to be a thread that had excellent pics of a properly jetted bike plug. Unfortunately, the 'upgrade' to the new look rendered them lost.

Most unfortunate.

Here's a tip, though...the color of the plug isn't the issue. You know that, right? What you're after is a ring similar to the one shown (hey! Where'd this come from? ;) )

Your looking for a such a ring to be approx 1mm thick. The thicker, the richer. The darkness of the ring will change with the time run.
