i have all the plastics and stuff just dont have them on, here is the problem, it runs and cranks easy i stuck a 350x carb on it today to crank it cranked first kick!, but has an god awful tap, any known problems with this motor to cause this? should i check vavle clearence first then timing chain? just hope its not carnk or anything, it revs good and no smoke, just loud tapping ticking noise here is a vid to mabey help

most of the bolts on the vavle cover look like they came from home depot there not the stock bolts, looks kinda rigged?

get them valves adjusted before you cause damage to something else!

[leevarnado]

i wouldnt run it until i found out what the noise is,take a head off and give everything a good inspection.also what part of louisiana you from,baton rouge here.

[350xmerk]

I'm not running the bike, today was the first day I cranked it just to see what it would do, I know better than to run it lol, just wondering the most likely cause lol, I'm leaning toward valves not set right, but could be chain,

Also I'm like between baton rouge and Hammond

[QUOTE=leevarnado;1032915]i wouldnt run it until i found out what the noise is,take a head off and give everything a good inspection.also what part of louisiana you from,baton rouge here.[/Q probably dont need to take the head off . if it runs good after adjusting the valves just run it.

[Xpress]

Try adjusting the valves before you do anything else.

Any idea on what thousandths? It looks like a 80ish model motor 80 to 81, thanks advice

[Dirtcrasher]

That is 100% not a 350X frame, may be an XL or XR or other frame modded...........

[leviblue]

it's a xl 500 ft section and a 350x rear.though that rear sec looks a little tweeked and can't really see the welds . I'd put a few gussets on it. it's cut the same as mine and the ft sec is spot on with mine.....the forks look to be 3rd gen R. pretty cool though

[350xmerk]

Ok so what back end is used is this a trike rear end? Here is my 350x http://i1127.photobucket.com/albums/l628/Asd59878/2646d873.jpg I thought I was the sane rear as my 350

[350xmerk]

Lol thanks leviblue, may I ask what's a gusset??, I have all the plastics and tank and stuff I'm itching to ride it lol, I do not like the way the frame is done at the bottom, he'll there is no frame they used the block as part of the frame, I will fab up the rest of the frame when it's running right,

What year xl500 is this any idea? going to buy repair manual tomorrow

[leviblue]

82-85 and the book covers both the xl, xr 500 and 600xl. looks to be a 350x rearsub. i looked at your pbucket photos and that is a scary weld. gussets are steel cut to strengthen the frame in weak places. mine was done back in 86 and have pics of it in my photo album on my profile page. does that exh exit in the mid of the rear fender?? cuz that pipe is all sorts of twisty.

[350xmerk]

Thanks for the info! And yes it exits in the middle, I'm guessing it's pretty nice little project then to get it for free lol, they guy gave it to me' ebb I bought my 350x,

Is this a fast motor, does it make a fast trike?

[350xmerk]

Also is the xl motor the same as the xr? Any differences?

[taz]

the motors are basically the same my 500x is the xl frame with no bottom im going to make a steel skid plate that bolts the front and back of the frame together

[250rRoostmaster]

That is 100% not a 350X frame, may be an XL or XR or other frame modded...........

It still has the XR footpegs!!

[czlou]

10 to 1 The front Half of the Frame is a 1979/80 C&J XR/XL Frame. Sure Looks like the C&J XR500 I have

[taz]

what is a c&j frame aftermarket?

[czlou]

Yes it is was a aftermarket Frame Co. Started back in the 70's in Santa ana CA. Known for their Flat track Frames and for their Off road Frames. XL 250/350 XR500 and TT500. Google C&J XR 500. I have a C&J XR500 and a HHP C&J XR500 Very Cool Old School MX Bikes.
