Wanted / Stock Cylinder

« on: September 08, 2016, 05:50:14 AM »

Hello,

I am looking to get an idea of what i could buy a stock cylinder for. I do not want any porting or anything.

Thank you

So i got a pair of used KFX 450 shocks and had to do some grinding to get them on, but they are immensely better!

The KFX 450's front shocks do work. As with the other 450's shocks there is some grinding involved, but for around $120-$150 you can get modern suspension on a 250 R. And the KFX 450 has the exact same length shocks eye-to-eye as the stock 250 R front shocks.

Yfz 450 shocks work but you have to grind down the meat a bit on top of the shock. Just a little grinding and they drop right in.

Thank you for the idea. Do you know about the yfz shocks first hand, or have you heard this? I ask not to be a jerk, but because I am interested. Originally I removed the yfz from the list because i saw that it has shorter stocks and didn't want to lower my front end. What do you know about the effect on the geometry of a 250r with yfz shocks?

Thanks for helping me out;

Howdy,

I recently blew the seals on my stock shocks (1987 250R) and am looking to replace them. I am not looking to spent over $200 and luckily i can find stock front shocks off of 450's in my price range. I have looked at the front shock lengths off of the TRX 450, YFZ 450, Predator, DS 450, and KFX 450, and at this point am only considering the KFX and TRX.

The KFX 450's front shocks can be found for $50-75 cheaper than the TRX 450 shocks and there are more KFX 450 shocks on Ebay than TRX 450 Shocks. However, I know that with some light conversion work the TRX 450 Shocks will fit my 1987 250R. What i am hoping to figure out is if the KFX 450 Front shocks will fit a stock 1987 250 R ?

As always thanks for your time.

Carburetor, Intake, and Exhaust / Reeds

« on: February 29, 2016, 08:03:47 PM »

Short answer to "Havinnoj": Yes.

Long Answer to "Havinnoj": I have the upgraded exhaust, but with the current setup of my bike the stock exhaust fits my riding better. I am not a duner or a racer. I do more trail riding. With the upgraded exhaust I can go faster, but i have to stay higher in the RPM's and if i get slightly bogged down during an hill climb the bikes stalls and leaves me stopped halfway up the hill.

I am interested in the Carb/Reeds because I rode a bike (1988 TRX 250R) with these upgraded parts (Carb/Reeds) and noticed that it had better acceleration and top end power. I am trying to figure out the effect on performance from someone who has upgraded these parts.

Carburetor, Intake, and Exhaust / Reeds

Howdy,

My 1987 TRX250R has:
-Stock Air Intake (Box, Intake)
-K&N Air Filter
-Stock Carb
-Engine is Ported for MID-range.
-Stock Exhaust (I have a mid-range Paul turner pipe, but this reduces my low end power more than i am willing to accept)

I am interested is upgrading my carb, or reeds, but I am "New-To-This".

My questions for you are:

-Have you upgraded your Reeds? Cost? Effect?
-Have you upgraded your Carb? Cost? Effect?

Thank you for your input!

So...I tried draining the gas out of the tank into a gas can and noticed that when i had the petcock on "on" NO gas came out, but when it was on "res" gas DID come out...I think that this was my problem all along. I was low on gas! Yup...

Howdy,

I was out riding over the weekend and:

-after about 30 minutes of moderate to aggressive riding my bike stalled.
-I thought it was the plug, but after pulling the spark plug there was no visual problem. To double check that it wasn't the plug i installed a new one, but this didn't fix the problem.
-I could get the quad to run with the choke on, but it would die 15-20 seconds after turning the choke off. It acted as if it would run forever with the choke on.

During that same trip and about 15 minutes later i got sick of being towed back to the truck by my brother. I started my bike and unhooked the tow strap; everything worked fine (i was riding moderate to aggressively). I rode for about 10-15 minutes until i got back to camp with out any abnormal behavior from the quad.

Thinking that everything might be better and after i had gotten home i tried riding it around the neighborhood and it was having the same problems as before (stalling).

I am coming to you guys to help me figure out what might be causing the stalling.

I have switched out my paul turner "TRX Race" pipe for the stock exhaust and my bike is much better.

I have the stock exhaust for the bike and am working on re-installing it. I want to see if the stock exhaust will give me a more linear power band.

 I had about 1/16 of an inch of carbon build up in the paul turner pipe and plan on roasting the pipe over a fire to try and burn it out.

I think it's the stock carb. I have seen it on 4/5 250r's that i have seen is why i think that it is the stock one. And thank you think she's pretty aswell.
