Thanks, mostly what I had gathered minus the part about the lobes, my new tensioner should be in tomorrow so I can slap this thing back together.

Nice bike Fish.. if only I was still working.. I gotta finish up this 650.. sell it.. then fix up a 500 I just picked up as a "part out" maybe I'll keep the 500 and sell my 450.

So I searched the Service Manual and the Rincon forums to no great success. I'm wondering if anyone here knows how to set the timing chain on a Rincon 650. I dont understand getting TDC on a compression stroke when the valves have to be off to put the new chain on the cam. Most I could gather was the "T" mark needs to be in the sight hole, and the long hash mark on the cam gear lined up with top of cylinder, the 2 short hash marks lined up parallel with casing. If that's even right on setting the cam. Once I get that in I can check timing when it goes back together.

Gotta love honda frames. Weld got a bit messy, apparently my wire started rusting and was sticking in the gun.. made the weld spotty, but will hold way better now

Yeah Jeep, only one of the guys I ride with has liquid cooled, efi, auto.. we spend more time pulling him out. We finally told him go buy a honda, if you bring that thing again we aren't going. We all ride 300s, 400s and then me with my 450. I love my 450, I go right thru stuff they get stuck in.

I'm sure it's great on the trail, with the IRS but I mud.. aside from the fact its automatic. I'm not a fan of water cooled engines in the mud, I've seen way more radiators get plugged up with mud than I've seen motors so encased with mud they overheat. But aside from that, I think it'll be a fun bike for the wife. Plus she gets to feel good that my 450 with a GR can't keep up.

Yes, it's an automatic.. yes my 450 will outlast it.. but the 650 is for the wife and I picked it up cheap.. I just want to see the power difference. The 650 will not be getting put on 29.5 outlaws. Maybe I'll put 26s on it but its mostly staying stock unlike my 450

It's completely off.. need a new one.. plus I'll do the timing chain since I'm in there. And it's a little loose.. and the oil seal on the front cover was leaking.. sigh.. so much to do.. but i really want to compare the 650 to my 450

So I put the 450 on back burner.. decided to get on the 650.. I think I'm looking at getting a new frame.. all it needed was a new oil pump chain.. and I go and disassemble it and find rot

I didn't spend a dime except the new winch cable. I used the head and piston and rings from the parts bike. Steel cable because I can't use synthetic in my real unless I get a barrel from warn. I prefer SS cable over synthetic for s couple reasons. But I snapped it cause he was stuck stuck, in reverse I was winching myself in.. so I tried yanking.. bad idea

Well good news bad news and some funny news.. good news is not smoking anymore and runs strong.. took her out to sabine atv park this past weekend.. bad news I avoided mud cause I snapped my brand new winch cable pulling my buddies Polaris out of a hole, and my timing chain needs to be replaced.. its slapping.. and need to clean the carberator again.. but she made it the whole weekend with minor hiccups.. then I rolled it going down a steep incline when I caught a rut from a sxs.. flipped her over.. fired back up.. rode rest of the day

Yeah, the job was coming to an end, so we laid ppl off and upped hours and days worked, barely had any time till I finally got laid off

Hey all, I know I've been dark for awhile now, work was killing me. I hadn't touched my 4 wheeler since my last post, well I got busy this week with it. Had to get it running right for a ride next weekend. It was a mosquito spray bike before, so not having a job now and no extra cash to spend, i pulled the piston and head from the parts bike.. barely smoking now, fixed my fan to a toggle switch so I can kill it before getting into some water. I missed riding

Well, work seems to be determined to not let me have time to work on my bike. I really haven't made much progress.. but definitely gotta take the spare jug to get bored.. has some very fine pitting that's too much to hone out

Wait.... ATVs have brakes?! .. guess none of us around here have working brakes cause the mud gonna stop ya. Lol FF, I would love to ride out there, just not my bike, it'd kill me or someone else

We do have an abundance of slop and mud down here.. maybe if I lived somewhere dry, I'd be more into trail riding.. but than I'd have probably tried going with a Trx450R

You are exactly right.. it'll never be 100% but with the right steps and precautions you can limit your chances. Although... what we were to build one of them sealing tanks they use underwater for welding around our engines?! But no seriously, I work on a big construction site, we constantly tear down small honda engines for being submerged in the mud out here.. generators, trash pumps, SXS.. all fairly simple, quick.. but then again I do this fairly regularly

Also, since this started as just a question and is bleeding into a rebuild any way we can get this moved into or since the threads are ongoing would it be problematic?

Waterproofing is fairly easy, aside from going to deep with an unhooked snorkel. (Which is something I have to fix and realign) however I will NOT do what it looks someone previously tried to do and epoxy the case halves. Proper gaskets, proper torque and torquing patterns work miracles on waterproofing. So you are saying Namura is high dollar? Or that they work wonderfully in place of high dollar kits? I spent many years as an aircraft mechanic, I'm not one for using silicone or rtv to seal things up. Gaskets are designed for that. I'll probably keep this thread going as I rebuild/build this bike up just for ideas/suggestions/possible help to others with pictures and ways to do things

I'm actually going to attempt to bore an hone the cylinder myself (cringes). If that doesn't work I will send the other cylinder out to shop and was looking at either weisco piston or the namura piston kits. If anyone knows anyone that can do the machining work to make the 26T primary gear fit. I'd love to know, I dont have a lathe so I won't be able to bore out the gear properly. 3 motors for 2 450s, I have a little room for error. I know the 26T primary has to be machined out and the stock primary needs to be broken to get those really soft brass bushings out to fit into the 26T that's been freshly machined. I just don't have the tools to do that.

Update *** bottom end seems good so far on parts motor aside from the goopy oil water mix oozing out, stripping it and rebuilding it

Thanks shade. So far its been a nice experience

! those came out looking great. I might look into that

Thanks. The rims were already on this bike when I bought it. It had 28" itp tires, but they were bad. So I found these 29.5 outlaws. At 1st I got them to try and trade for some 28 vamps, but I really liked how the outlaws fit and performed in the mud. Let me see if I have a pic of the bike prior to me starting my OCD trip on it

Considering I have 2 steering shafts this may be very doable. Time will tell.. this may become a 3 year project like my last race car was lol
