350x rebuild questions

[smvorndran]

I'm rebuilding my 350X thanks to an exploded case from the previous owner not maintaining the chain. My cylinder is worn, and I was wondering if anyone has experience with rebuild kits from GHDiscountATV on ebay? I looked through old posts, and the last note was from 2008. Anyone used them recently? $220 for a bored & honed cylinder plus matching Wiseco piston kit and gasket set. Not that bad of a deal.

Also, replace all bearings in the engine while it's apart, or just the crankshaft bearings?

Can I have my valves ground? They have recessed edges. .005"-.010" would clean them up. Do they have a coating on the faces, or are they just through-hard?

I haven't read the manual yet. I'm saving that for the assembly.:lol:

Don't worry Dirtcrasher, it will end up better than HoosierDaddy's 350x rebuild. Just kidding Rob.:p

I have used G&H before I must say, they did one heck of a great job. They bead blasted the cylinder, bore and honed the jug with a new wiseco piston, and even included a top end gasket set for 220 bucks. Not bad at all. Plus their turn-a-round time isn't bad either. Once I sent them my cylinder, it was about 3 weeks before I got it back. I also reccommend that you have your valves done to ensure the most possible compression.

I had a valve job on my 200x done by them.Im happy with results so far but im just an hr past break in on it.

Glad to hear :lol: Did that thing actually ever run??

If you had an internal explosion, you may wanna scrap the tranny bearings. Whats it add? another 100-150$, cheaper at a Ind. bearing house......

Just check them out, I re use them often as long as there smooth. But, when we have them all torn down for a complete overhaul/powdercoat I chuck them.

Depending on how long your keeping this, you may want to replace the timing chain and guides and get a take off oil pump in there or a 300EX modified.

Hows the clutch?

I would send the head out to be professionally done, I don't touch mine and the valves do get hammered after years of abuse. Good time for stainless steel studs in the head too.

Just my thoughts; I know it's allot of extra stuff but I only like tearing things down and buttoning them up one time, then enjoy 10 years out of them :)

I think Rob sold it non-running. I would have bought it off him and got it going.

I sold my old 350X a few years ago, and have missed it since. I'll probably keep this around for a while unless I stumble on a minty one. I'll check the oil pump specs, and see how she looks. I think it's on original bore, so the pump should be low hour. I never actually rode it. It was running when I bought it, but I brought it home and tore it down right away to fix the chain damage. When I got the engine out, I noticed there was fiberglass on the back seam. I popped that off to reveal a heliarc job. The heat from the weld warped the mating surfaces, so they tried to fix it that way. I have some ebay cases coming my way this week. I'll send the top end out after I get the lower end split and redone. I want to make sure I don't fubar my lower end before I spend the money on the top.

I have a local Carquest machine shop that can redo my valves. I know there are some machines that say don't grind your valves, but I've done it anyways, and they always run fine afterward.

Where do you get stainless studs at? I have to drill out 3 studs, but I work at a machine shop, so it will be pretty easy.

I only paid $200, and figured I stole it. After I get done all I want to do to make it reliable rider, I'll be near $1000-$1400 probably.
