Hawk Header Help Please!

[blackhawkdown]

Hey men I really need your help on this one. So i bought my hawk last summer but due to my mother being diagnosed with breast cancer and me having arthritis I havnt had any time to ride my hawk. I only started her once last summer and once this summer and let her run for 5 mins. Started with the good ol kickstart and stock fluids/plug so I Im really happy my blackhawk is still alive on life support shes just running lean and needs some more power. Im changing all the fluids specially oil and basics but im also going with an aftermarket header and carb/filter(my airbox was terrible and the seal was non existent). For the header ive read in other hawk exhaust forums that there are two types flange mount & slip on. Im having a hard time telling between the two but ive removed the carb and header and taken a picture so you flock members can help a brother out with deciphering what I have. I think its a slip on but im not entirely sure. Soon ill have this baby airborne thanks to this forum and cant wait to share pics when she is!



Also is this yoshi a slip on?

and lastly would this bad boy possibly fit? I found it outperforms a yoshi and has a megabombish expansion chamber which i love! First two are pics of the belparts exhaust system second link is youtube video yoshi vs. belparts...Thanks for your time gentlemen any help is appreciated!!!

That is one that most people are using. A couple of guys are using the other one that doesn't a have spark arrestor/screen and that is why I went to ebay to find the one listed above.

thanks for your input hertz I actually know about that exhaust i was mostly wondering if my setup is compatible with a slip ons like that and if the other two that i attached pictures of are slip on

Your pictures look like stainless steel. It won't bend like aluminum to fit your bike.

Which exhaust are the pictures from? It looks like an FMF exhaust.

not likely an expansion chamber, more likely a catalytic converter.

seems like it would interfere with the clutch cable, maybey not but definetly close.

Im almost 100% sure its an expansion chamber and not a cat. Your right the clutch cable and header mount are my two biggest worries but the expansion chamber and exhaust kit at 300-400$ is almost too hard to say no too. Heres another youtube video of the Belparts outperforming a yoshimura in a dyno or sound test possibly. This and the other video i posted have me convinced its an expansion chamber and the brap is undeniable. Sounds just like my best friends 06' WR250X with a megabomb header. Just my two cents and thanks for yours jimbo slice!

Also does anyone know if this yoshi exhaust fits?! I dont know why itd be on a hawk250 site under the upgrades section if it didnt but ive read every exhaust forum here about hawks and china bikes and they say nothing about yoshimuras. It seems like the pipe here is one full piece i feel like it might be an issue getting it to fit on the hawk would love anyone's opinion

just my opinion...not sure if you would find too much on the subject of name brand parts anywhere on this forum. I don't think many members would be too receptive of putting an $400 exhaust system on a hawk with so little to gain. (but then, i don't get out much)

Good luck to ya, looks h.q.

It is similar to the Pro circuit t-4 I've installed on my Hawk,the t-4 was listed for the crf230l too so the yoshi should fit with some modifications.

I dont intend on bending my exhaust ive removed the stock airbox & carb and freed up a lot of space seems like the only choke point is by the clutch cable. The exhaust in the pictures is a Belparts CRF230F exhaust and it outperforms the yoshi from my understanding. It is a brazillian company and they have some great headers on the market with the fmf style which i love. I wish I could just bolt on a fmf megabomb but i know thats almost impossible on a 230 as there are no years compatible only powerbomb :'( Belparts makes a megabombish like header with a FAT expansion chamber heres another youtube link with it on a crf230!

wish I could find out what if anything is inside the
power bomb / mega bomb....
quite easy to build with a couple of Stainless cones..

Nothing was inside the "FMF PowerBomb" header on my Kawasaki KLR 650... just an open pipe with an "expansion chamber"...

PowerBomb Header is designed for extra HP/Torque at higher RPMs

MegaBomb Header is designed for more HP/Torque at lower RPMs

Thanks
good info...
now just find a good piture of a Mega bomb on a 250cc bike so
I can take a scale of a known size part of the bike then
measure the mega bomb useing that scale...

I can't imagine how I would build a stainless cone in my shop. A slip roller would be one way, but I don't have one (yet).

[pete]

You can buy them... for joining tubes of diffrent dia's
i havn't got a set of rollers for cones that small either..
