Better yet...you are running a risk of not having a safe bike when you are done, I mean the jet fuel you use may leak out get over the engine, and cause a massive fire, burning you beyond all recognition. Now, since NONE OF US WANTS THAT, just give me a call when you put her back together, I will come down and try it out for you. That way, when someone posts that Neal died happily on a motorcycle as it went up in flames, it won't be the Neal that has to keep Subsim running but it won't be a lie either.

I have had a VFR400 sitting in the garage for 3 years with it's carbs in bits.

One day I will fix it....one day.

Sorry for going OT...
This is redicolous!
The price of a new visor for my helmet is more than the price of a new helmet (inc. new visor).
I furious!

We already survived one SS fire for the year. There are no more scheduled.

I suppose that's typical nowdays! I had a TV tube that had a burnt out heater for the red gun, the store had one instock that they were going to throw out because the TV model is too old to repair, however they would sell it forthe listed $480, I said that's rediculous I could buy a new TV for that, I offered $200 but they refused, so they tossed it! (wish I knew where) talk about stupid!, that was panasonic, won't buy one of them again out of principal!

a nice tip for carb cleaning is to use iso alcohol 90% as your carberator cleaner for soaking parts.

its a very very good cleaner, is safe for hands and the fumes dont hurt your lungs.

its also safe for rubber and plastic so unlike carb cleaner you can soak everything overnight and brush it clean with a parts brush then blow it out with air to finish.


getting enough carb cleaner to submerge your entire carberator is expensive and very toxic so next time you need a cleaning try it out.

the one draw back of it is that it needs an hour or so soak time because it works like a varnish stripper and wont clean on contact like carb cleaner in a can does.

*edit* If you are really, really lucky a local mechanic might have a jet-testing box.

balanced airflow into the carbs can have a big effect of carb sync as well so make sure both filters are clean and in good condition (im sure you did but i say it anyway just in case it was overlooked)


i was told by a very good bike machanic that i trust, that needles wear down very easy and before its enough to be easy to see, it will have already been effecting how the bike has been running for a long time.

his advice to me was for the price it costs it makes sense to replace the needles and jets whenever you are having carb issues you cant seem to resolve. he said bad fuel air mixtures are more damaging to a bike engine than dogging it.

From experience...needles dont wear...they just slide up and down

...what you should make sure of is that the seals ( which look like rubber seats ) are properly sealed...after rebuilding the carbs I would start at closed and open 2 turns then adjust from there...I used to do mine by starting at 2 turns open from close and go 1/4 turns from there....never did the vacuum hose thingy...just by ear
like I said earlier..also if the exhaust is modified...I would bump the jets say from 35 to 37 or 38....

Believe me, they do.
