Houser crf hybrid issue

[mxracer39]

Hey guys, bought a Houser hybrid frame a year ago. Was told its an 05 for the 05-07 crf. Finally got around to getting an 07 crf450 dirtbike for the motor, pulled the motor and found that the lower motor mounts on the frame are about 1/2" too narrow and the front motor mounts on the frame are about 1" too narrow. Is this not actually a crf frame?? Did I get taken.

Thanks

Wouldn,t that frame been built for quad motor in 05 than dirtbike motor? cause i thought dirtbike motor,s trans case is different than the quad?

No the cases changed on the Crf 450 motors, I'm trying to get a handle on this as well. So if anyone doesn know the exact years they changed please chime in. I think its just one change, like 02-03 were the same then 04 and up are the "others" but thats a guess at this point.

I think I found the disconnect. This houser frame was listed as an '04 in late '08 and purchased by g9901920 http://www.exriders.com/vbb/showthread.php?s=&threadid=366677&highlight=houser and then the same member relisted it as an '05 in early '09 in this thread http://www.exriders.com/vbb/showthread.php?s=&threadid=383349&highlight=houser . I think this is the frame i ended up with. I purchased in late '09, same color with sparks swingarm and pipe. From what i was told the crf motor similarities go up to 04, then 05-07, then 08 on. Does anyone have a measurement on the front and lower motor mount width on an 04 or 03 crf motor?

Im almost positive all houser crf frames were built for the 02-03 style engines.

02-03 lower mount is about 3 1/4 in. to 3 1/2 in. , 04 is 4 in. my chassis fits 02-04 my 03 motor has a spacer on oneside (taken off the dirtbike) not sure about the front mount though i could check tomorrow, if u want just pm me for more info.

let me know if you want new mounts to weld on. might be tough trying to save the old ones.

[mxracer39]

Ya, my lower mount is 3 1/2" and the front mount is 2 1/2". Looks like it is set up for the 02-03 motor. Not sure if i want to hack it up, deep down I'd like to get a walsh or leager anyways, maybe this will be my reason.

Thanks guys

I wouldn't, there are a bunch of 03' motors out there.

[atvmxer79]

if u get someone who knows what they are doing then it wont be a hack job.

or sell it to me :D

[mxracer39]

Ya, I'm thinking I might sell it. I could fabricate mounts no problem, I just dont want to cut up a perfectly good houser frame.
