how do you start your 150?

[Veteran]

I did the 45 pilot jet mod and the bogging is pretty much gone.

However I struggle to start it cold . I tried the choke , pumping the gas and keeping a bit of throttle in when I kick. What trick do you use ??

Hot start seems easy enough.

The bike is not used yet so is not run in yet.

[haf2race]

gas on, choke it and twist throttle 4 times, let off throttle and kick.

[k2rider]

I turn on the gas, pull the choke and it starts 1st kick...

Keep in mind that we have an aftermarket MRD header/pipe combo.

Since when is changing a jet considered a "mod?"

With my mods it has a bunch of power and performance but it's a pain in the butt to start when it's cold. I just make sure I got my gas on, choke on, and then I crack the throttle the moment I kick it(takes a few kicks, only starts in one kick once it's warm). Then I usually let it sit and idle for a few minutes and burp the throttle a few times and then it's nice and warm and ready to ride.

A mod is a change from standard.[dictionarty- an act of altering something from its original state] But I guess most people know that.

I think a jet is an improvement. Whenever I think of mods it's something bigger. I like mods better ?

[crf150f guy]

with the bigger pilot the bike should start easier.

Just a guess but im assuming it's hot in South Africa? Maybe the jetting is a little rich for that climate. If you try starting it with the hot start and it starts easy then you are too rich! Good luck on the (MODS). LOL

What exactly does the hot start do? does it lean the bike out ? Not too hot here. Probably about 70-80F at miday and 60F in the mornings. Winter is a little cooler ,about 20F less.

I kinda got it to start easier but still not as good as my 450R. Will try the hot start .

The Hot Start leans out the mix the opposite of the choke. If you need to use the Hot Start when the bike is cold your pilot is too big. 70 to 80 midday is fairly warm you may be too rich. Read this link it will help you understand jetting better.

Tonight I tried something:

Fuel on,

choke on,

3 quick twists of the throttle,

Set at 1/4 throttle

One kick..............

Started pefectly and stayed idling. It has NEVER started on one kick.

So it may be a tad rich, but bog is gone and starts perfectly the way above.

Should i stick with the 45 pilot ?

That is how we start ours and the same result. Stick with it for awhile if it gets too hot temp wise, you may want to kick that pilot down to a 42.

It IS a "modification" of sorts isn't it?

Mine is a bitch to start cold, PERIOD. After that, it's a breeze. It's an '08, what to do? Deal with it? I can live with that.

Hello, with 2007 with valve shims right stock jetting starts fine. Bought it used reshimed valves starts perfect sometimes without choke!

[jaulmer]

Hello, forgot to mention intake valves way to tight, and this bike i bought was never raced. It rides in the woods now.

The bike is not used yet so is not run in yet.

i tried to ride when it was 25 deg. out and it took 10-15 min to fire up, the next day it was 40 out and it fired up 1st kick...

If it's really hard to start. Shut the gas valve and tip the bike over so most of the gas from the carb comes out.

You should be able to start it now.

Why dont you just drain the carb then.
