Long story short, I blew my motor and now there’s a hole right where the balancer is supposed to be on the right crankcase. So, I would basically need to buy a new right side crankcase and transfer or replace everything to it and I wanna know if it's doable to do myself even though I don’t have much knowledge as to how I would do that. I have the service manual but want to know your guys’ opinion if it’s something that’s possible. Thank in advance.
Haha, yea M_quick that's what's left of the Piston. Pretty destroyed.
That's very good to hear cataway. I've read that they need to weld on weight to the balancer to make up for the added weight of the stroker and big bore, or something like that. But since you say it worked just fine without doing that then that makes me feel a lot better. I was feeling kinda discouraged haha.
That's what happened to my original trx700xx, but not that bad! And my damage was only to the top end. I did add the stroker crank, even though I had no crank damage. Your looking at some expensive parts. I can't view your photos on my desk top, but I'd say your valves are probably bent, and maybe a cracked valve guide or all four. I know I put over $1500 in my motor when the piston went, and cracked the jug. So you may want to reconsider that engine on eBay from Wooster, Ohio. I messaged the seller, and he does have other parts for quad, just not listed.
Edit: Never mind, I just looked and the one for $1750 plus shipping sold on the 16th.
:frown:

Not sure why the pics aren't showing up... But it does suck that it got sold already. My only hope now is to continue with rebuilding it my self or get the rebuilt one on eBay for 2800$, but if I'm gonna do that, I'd rather see if I can do it my self.
I'm guessing the costs are gonna be near 3k$ right? Since I'm gonna buy an exhaust and the PCV as well.
And the valves look pretty bad too. It's in one if those pictures, don't know why only 1 of them shows up. I'll reupload it
Okay, I'll try that. I'm also gonna send pics of the shift forks and drum. Not sure what I should be looking for. But I did have a problem going in to neutral at times. The gears themselves don't look too bad though
Yea, that sounds a lot easier, especially since I don’t have a hydraulic press haha. And yes I am. I’m gonna be getting the whole bottom end rebuild kit which comes with bearings. Or I’m I wrong?
Got the crank out with some heat.
You think it's necessary to get new bearings though? The ones that are there look normal.
Also, just checked one of my valve guides and it seems kinda cracked. What's a good and easy way of taking them out without any special tools? Thanks.
9-16 in the service manual. If married do this when your wife isn't home, or if you live with parents do it when there gone, lol.
turn oven to 275 and place head inside for around 10 mins or so. Says to use a valve guide driver, but you can use anything from a piece of steel, allen wrench, or socket and extension that you don't mind beating on. If you have the new guides put them in the freezer while doing this. before messing with this, check your head to make sure it's not warped. This info is 9-14 in service manual.
I have a heat gun that gets pretty hot, that's what I used to get the crank out.
When installing new guides, how far deep am I supposed to go? I really hope the head isn't warped, that's like another 500$...
And as for the bearings, I'll clean them with brake cleaner, that thing works wonders. Then I'll let it sit in new engine oil. What do you think?
I'd steer clear of the use of a heat gun on the head. Read over the manual, and you'll see how easy it is the check the head for warping. Also you will also see not to heat the head over 300f. A oven is a controlled heat source, and will bring the entire head to the same temp. A heat gun is directional and not controlled.
How would I go about getting head work? Take it to a shop right? And if I don't do head work, it doesn't make sense to go +1 I'm guessing? And I'll look into RHC, haven't heard of them but the kibblewhites are so much more expensive than OEM.
Also, I got the valves out and see that all my guides are broken and all the valves are bent... Gonna stick it in the oven, I really hope I can get them out.
i had RACERS EDGE do a +1 on the valves and a i had RHC do a +1 on two different head . soooo..... i got to compare the work .
RHC does a much better job
it does help tp clean-up the intake port " For every 1 CFM of increase in intake flow, you'll gain .43 horsepower. "
but,... hard to know how much you have really done/helped with out a flow bench.... mixxer was a great one for dong a big bit more than should of been done .
Man, seems like there’s a lot to think about when it comes to the head.
How would I go about hardening the rocker arms anyway?
I live in the east side at Miami, Florida. I have a friend that knows a guy that can help us with porting it since he’s thinking of porting his head as well.
What if I just port it and not do the Valve job, would it make any sense to go with the +1 mm? And if I don’t do +1 mm should I go with kibblewhite or OEM?
I’m thinking they’ll replace my valve guides too right? All 4 of mine are cracked. Managed to get 1 out by drilling it through but haven’t tried putting it in the oven yet, don’t wanna drill the other ones through if the oven truck works and it’s a pain to drill them out. I know it’s a lot of questions guys, I really appreciate all the knowledge.
I'll take the 1st. question. You have to have them hard welded. Lot's of places do this, they require a core charge or old usable rockers & cost anywhere from $200 and up for all 3. This is a good idea, but only required for use with aggressive cams or any web cam.
I believe I know someone that will have a stage 3 hotcam for sale some time soon
