Mikuni TM40

Hows it going?
I am thinking of buying a Mikuni TM40 Pumper Carb, I am hopeing it will help when trying to start the thing after dropping it. At the moment the bike starts really easy, until it has spent a few seconds on its side, then it is a nightmare.
Any ideas?

I have a Mikuni fitted to my bike and I love the difference the pumper has made.

However it is not much different or easier to start when it has been on its side.

The procedures are the same as for the standard carb.

I try first , find tdc, hold the throttle fully open and kick - sometimes it will start.( often referred to as the racing start)

If not :Turn the fuel off , pull the decomp in and kick through approx 10 times, find tdc and kick with decomp out. It should start very rarely I have had to repeat the procedure but have never had to do it three times.

I should add I do not turn the kill switch off and often hear it fire through the air box when I am clearing it out( kicking it through with the decomp in). This may be a bit foolish as I have heard of one pig going on fire doing this but as long as it starts it is a chance that I am willing to take

Hope that helps.
One of the best bits about the mikuni is that on tight snotty trails it can be at the point of stalling but wack the throttle open and it literary jumps forward and away.

Yea, thanks for that. I was hopeing to fix the flooding problem, but I think I will get one anyway. They sound good.
I am thinking of doing some adventure touring and Im sure this carb will be benificial for that.

I see on youtube an edelbrock carb, the guy lay the bike sideways left and right and didn't floaded it, the bike was running on its side so I think that's what we need. if I find the link for the video I will posted if not you can find it on youtube.

Edelbrock discontinued, spares too.

Had anyone managed to install the FCR 41 on a pig with the big acerbis fuel tank ? I have spent days reading about carbs and feel even more confused than before , it seems that the FCR is the best carb you can buy but does not fit , and i dont really want to modify the tanks and other bits , need something that fits straight in . Does the mikuny TM 40 realy have a problem with the slide sticking ?

Yes, in the same way that the Pig's starter button often breaks.
Now wheeeeere do you get that nonsense?
Oh, nevermind, no!

I have ruled out the FCR41 it is too much hassle to fit and set up properly , shame as it is a very good carb .
It seems that the stocker and the TM40 are the only options since the edelbrock is gone forever

"Apparently.." yeah, but a shoddy explanation that. Nutting rong with a TM40, especially so when bought new. And, as long as you don't compete in the top-class SM it performs as well as an FCR, only the setup is easier. Fitment too, plug & play, and jetting info aplenty.

What carbie are you running Burpie ?

Guess?
Yip!

Anyone have any updates on the Mikuni 40TM-6 pumper carb. Do they hold up well?  I have resisted pulling the trigger for one. Are parts still easy to find?

I only bought mine a few months ago in the UK (brp'ies aren't that common here) so I would say yes.

Also don't they use the TM40 on other bikes to (harleys?) so i would say you shouldn't struggle for parts

do you like the way the Mikuni performs?

Yes, no, wait, YES !!!

Hogakaharold, are you the Hodaka-man of the tank braces fame?

wouldn't that be http://www.xr650rforum.com/u2

There is a Hodaka Guy on this forum and probably other forums that may sell some neat items but it isn't me.
I had a Hodaka 100B+ as my first bike back in 1972 and was called hodakaharold in high school. I still ride a trail bike and do the adventure bike thing except my XR650R is a hoot to ride as a dual purpose plated bike.

Of course, good ol' Hodakaguy!
Was just wondering, Hodaka is a name not very well knows outside the States, so rare
