I already know i'm going to get 2 new sprockets both the front and the back ones to increase overall speed, but still try to keep my power down low.

This will be hard to achieve, as one will cancel out the other. :eek:hno: I'd personally stay away from the 13t front sprocket. I have a 14 one my original and a 15 on the other. With the added mods they both pull really well down low.

I think mine now has a 14t up front and it has a lot of power down low but only get up to about 65 before topping out and feeling like i'm pushing it too hard. I'll probably keep that one but my back is eaten up from wear and tear so i'll need a new one of those before too long.

Sounds like you had a issue before. I'm like 225 lbs on a good day without gear on, and I've had both of mine over 80mph.

Yeah, I weighed around 150 at the time it was running so definitely something wrong, I'm just not sure what it could be.

Hey M_Quick, did you have to shave the chain guard to get the 15t in or was it not necessary?
I did grind on the case saver, for extra clearance. It did go on without grinding, but was really close to touching, so I opened it up a quarter inch or so. I'm not sure if it was necessary or not, but I sure felt better about doing it, than I would of had I not.

Glad to see a fresh thread and im not the only guy with one left. Ive been having upper end issues and the guy at Duncan basically told go for the gusto or dont bother and stay stock I loved this thing for the 10yrs ive owned it but this builder has really just worn me out with problems. Most scary thing about the lower or anything cool is they never post again after they start the build so you never know if it worked out or wasted money. Good luck and let us know how it goes

I know, I tried to do what I like in posts but don't see very much. Be very specific with my problems, post too many pictures, and explain the end goal so if anyone with similar problems or ideas then they can learn a little bit from my experience before they start on theirs. I am waiting until at least tomorrow to buy any parts to kind of finalize my research and see if a big bore kit is worth the extra money. I probably will end up getting it, just want to be sure before a big purchase happens. But i'll be sure to keep everyone posted!

*** UPDATE ***

Finally back out there and got the valves out and to what M_Quick was probably trying to get me to check, 3 of the 4 valve guides were cracked and 2 of my valves were barely bent. I'm not sure how bent they need to be to be unusable but i'm sure that any bend will cause problems. So I'll probably need to be looking at getting all new valves and new guides? I'm not sure what's it's called but the section of the motor where the valves are located. I tried my best to show the valves and guides in the pictures attached to this. As far as cracking the motor open, it has came to be impossible for me to do it by myself with given I don't have air tools yet to help me. I seemed to get everything I need to off except the nut holding the clutch on? It's behind the 6 spring loaded bolts and spins whenever the motor doesn't. I've tried putting it into gear and I don't know. I'm sure i'll figure something else out or one or the people reading this will have a better idea than me, but as of right now, the motor is still together and I have no idea how to get it apart. I just look for something that may be holding it and try to take it off. Doesn't seem to be working so far sadly.. Haha Any ideas would be very very much appreciated!

That part with the valves is called the cylinder head, I suggest you take it to a shop to get the new valves installed. It's kinda hard to do on your own. And as for that part spinning is because you need to get a tool called the clutch holder to keep it from spinning as you unbolt it. Do a quick Google search for trx700 clutch holder and you'll see what you need.

Okay, I plan to take the cylinder head to Southern Honda Powersports whenever I go back to my hometown so they could see what one will cost and see about the valves and stuff, as for the part, I ordered it and it should be here tomorrow. Once I get that, I shall attempt to split the motor yet again and hopefully have more luck!

Finally got the motor split using that clutch holder. Thank you Kubi! figured out that i'm really glad i split the motor because during the slow process of splitting them apart, sooooo much metal came out of where all of the gears are and lodged into places that i'd never get out had i not split the motor. My garage is the messiest it will probably ever be with everything thrown around and parts everywhere. Looking at everything on the floor, it's so intimidating thinking about putting it back together. I hope that when i get to certain parts, my memory will spark but first i have to buy parts and get them, then clean the motor. Once it's clean, I'll begin piecing it back together one baby step at a time. Until then enjoy these pictures which include my disaster of a garage and the trash that came from inside my motor.

Yeah it will be tough, but i should be able to get it done. I just can't get past the whole buying a whole $460 cylinder case just for those little cracks and spending 140 on valves because they are just barely bent. Aside from that, I could have it up and running very soon. Haha

Well you will for sure want to replace those valves. The cylinder head is probably okay, you just need to replace the valve guides. Now from what I remember your cylinder it's self needs replaced but, it's alot cheaper than the head!

Okay so I apologize for not replying or anything of that sort. Classes started back and i took a minor needed vacation to the beach with some family. But I haven't made any progress, I have attempted to remove the valve guides but have been quite unsuccessful using methods i've found on the web via youtube. I don't feel comfortable enough using brute force because if I screw up and break something, i'm out 450 more dollars. I'm basically to the point of taking it to some sort of shop and seeing if they can remove the guides, put mine in, and give it back to me. But i'm not sure the kind of shop to do that. I've never had to put anything in a shop because i've been able to do it myself but this one has stumped me. If anyone has any ideas of how i may be able to remove them or just reference me to the type of shop i need to be looking for, (machine shop, motor repair, four wheeler shop, honda), I would greatly appreciate any guidance at this point!

IDK what method you tried from youtube. Did you try heating it up in the oven? I'm pretty sure the manual will tell you the proper temp. And while waiting for it to heat up, place new guides in the freezer. As far as shops go, Idk your area, but any machine shop should be able to do this. If you want it port and polished then, I'd look at a shop like EHS racing or similar.

First I tried drilling them out and it may have done more damage than good. So then I tried using the old valve and a socket and a rubber mallet and couldn't get them to move. The oven is currently heating up with new guides in the freezer. I'm assuming I try putting the valve with a rubber mallet and see if that will work with the heat. Another thing i noticed was the new valves didn't slide into the new guides. I'm assuming the guides need to be heated with the valves cooled but not sure. I hope that's the case anyways.. Haha I bought all of the parts at the same time on partzilla so they should be right but idk.

You are correct when you say the valves won't slide into the new guides. You have the correct parts, its just that the valve guides will need to be reamed out to the correct size for your valves.

Well that's good to know. I will just end up taking it to a local machine shop and having them do it. I hope that they don't charge me an arm and a leg.. Haha
