my cr125 is still too damn tall.....should I throw in the towel?(short guy problems)

sounds very wise to me noobee

Hay k just 4 shits n giggles why dont u try lowering your 165 might rekindle the love

my friend lowered his 86 wr400 1.5" just for woods handling, him being 5'10 -5'11 it wasnt really a needed thing but it handled awesome. i would have to agree. that bike just loved to grass track

Hey guys got an issue with my bike. It has a lectron 38mm
Ran fine last time I rode it. Went to give it a rip around the dead end street...warmed it up, did one half throttle pull up and down the street. Then I gave it one rap of wide open 1-3rd felt great.

Then immediately when I went back to idle if I gave it ANY throttle it would bog like it was out of fuel. I got it to go back by giving tiny amounts of throttle and lots of revs and blipping the clutch to get the bike to coast back. I had it on reserve already.

Putted back to the shop, added 1 gallon of 40 to 1 premix. Same problem it would rip down the street one time then bog like it was running out of fuel.

I took the tank off checked the plug, it is fairly recent and was a bit wet around the edge with fuel but the electrode was dry, was getting great bright blue spark out of the plug. Did a compression test and got 160psi which is down from 180psi from a few rides ago but i used a different tester.

Pulled the carb out and adjusted the needle in 1/2 turn (richer) it does the same thing if not a tad bit worse. I can get 1 1-3rd wide oopen pull then it is bog city.

Fuel in the bowl seems slightly high but not that much and was like that from day 1.

So I pulled the exhaust off and checked operation of the power valves they moved freely, I then adjusted the power valve linkage as some have suggested on this site, checked everything sprayed wd on the linkage and centrifugal bits just in case. Shined a light into the exhaust port and the piston/walls have up down wear but do not seem to be seized or anything.

It starts with a bit of throttle and blows lots of smoke at idle an on rev. Even when warmed up.

On part throttle cruising it seems fine if you give it more throttle it kind of goes bwaaaaaaahhhhh then clears up a bit. When you go wide open the top end feels quite weak now but revs out okay, then you come back to idle and it bogs like its got no fuel!!!?

I am thinking the bike is/was running rich?

But I do not understand why this is a sudden problem? Maybe the spark plug took a crap? Clogged something in the new carb?

This bike is driving me off a fuggin cliff man.

I will try a new plug tomorrow but am at my wits end was supposed to go ride but now I have given up.

lots of smoke? blown crank seal??

How do I check for a blown crank seal?

Also all the vent lines blow free/clear.

well u gotta plug the exhaust and intake ports pull the carb n pipe then get a regulated 6 psi air no more in the spark plug hole it should hold that 6 pounds for 20 minutes kinda like a leak down test on a 4t lotsa smoke meens your suckin tranny lube the weird bog is air from the ignition side you all so might find an oily mess under the mag cover

posted a reply in your other thread asking same question

Getting a bike lowered is no big deal. Getting it to work right is, so call the shortest guy I know and get it done the right way the first time.
Now you adjusted the power valve,go back and check that. I move mine the wrong way one time and it ran like yours.

Hey guys.... Ignition cover was dry pulled it. a bit dirty back there but seems cool?

I have not found a easy way to put regulated air in the cylinder just yet :\

At this point I am ordering a new spark plug and then going back on the needle adjustment.

What would symptoms of a bad reed valve be? Only thing I have not checked it seems.

Grabbed the ingition flywheel and can move it up and down/side to side noticeably. Way too much slop imo.

I will probably start parting it out soon.

just put crank bearing n seals in it not that big of a deal its not ready for the parts bin

Actually wrecked my truck on friday so I will not be doing any offroad/track riding for a very long time. Insurance is fighting me on the value of it.

No truck in california means nowhere legal to ride.

if you can do some of the work it wouldn't be to dear to lower it
it works ok too - still plenty of ground clearance - as that isn't affected as much
my wr125 was lowered 50mm when I got it - I had to get it raised back up for me
I still have the cut down springs for KYBs . It needs spacers in front
needs a small plastic spacer in rear shock

Get some bark busters to fix your lever problem

I've got a question: if you lower the suspension, do you need to adjust the amount of sag accordingly? Like; shorten the amount of sag an equal percentage to how much you lower the bike?
